Salvation

Lucas Cranach (I) - The Law and the Gospel

Paul the Apostle, like Jews and Roman pagans of his time, believed that sacrifice can bring about new kinship ties, purity, and eternal life. For Paul, the necessary sacrifice was the death of Jesus: Gentiles who are "Christ's" are, like Israel, descendants of Abraham and "heirs according to the promise" The God who raised Jesus from the dead would also give new life to the "mortal bodies" of Gentile Christians, who had become with Israel, the "children of God", and were therefore no longer "in the flesh". Modern Christian churches tend to be much more concerned with how humanity can be saved from a universal condition of sin and death than the question of how both Jews and Gentiles can be in God's family. According to

theology, based upon their understanding of the atonement as put forward by Irenaeus'

recapitulation theory The theory of recapitulation, also called the biogenetic law or embryological parallelism—often expressed using Ernst Haeckel's phrase "ontogeny recapitulates phylogeny"—is a historical hypothesis that the development of the embryo of an a ...

, Jesus' death is a ransom. This restores the relation with God, who is loving and reaches out to humanity, and offers the possibility of '' theosis'' c.q. divinization, becoming the kind of humans God wants humanity to be. According to Catholic doctrine, Jesus' death satisfies the wrath of God, aroused by the offense to God's honor caused by human's sinfulness. The Catholic Church teaches that salvation does not occur without faithfulness on the part of Christians; converts must live in accordance with principles of love and ordinarily must be baptized. In Protestant theology, Jesus' death is regarded as a substitutionary penalty carried by Jesus, for the debt that has to be paid by humankind when it broke God's moral law. Christians differ in their views on the extent to which individuals' salvation is pre-ordained by God. Reformed theology places distinctive emphasis on grace by teaching that individuals are completely incapable of self-redemption, but that sanctifying grace is irresistible. In contrast Catholics, Orthodox Christians, and Arminian Protestants believe that the exercise of

who lead regular communal worship services. Rite (Christianity), Christian rites, rituals, and ceremonies are not celebrated in one single sacred language. Many ritualistic Christian churches make a distinction between sacred language, liturgical language and vernacular language. The three important languages in the Early Christianity, early Christian era were: Latin language, Latin, Greek language, Greek and Syriac language, Syriac.

Communal worship

Church service, Services of worship typically follow a pattern or form known as Christian liturgy, liturgy. Justin Martyr described 2nd-century Christian liturgy in his ''First Apology'' () to Emperor Antoninus Pius, and his description remains relevant to the basic structure of Christian liturgical worship: Thus, as Justin described, Christians assemble for communal worship typically on Sunday, the day of the resurrection, though other liturgical practices often occur outside this setting. Scripture readings are drawn from the Old and New Testaments, but especially the gospels. Instruction is given based on these readings, in the form of a sermon or homily. There are a variety of Church (congregation), congregational prayers, including thanksgiving, confession, and intercession, which occur throughout the service and take a variety of forms including recited, responsive, silent, or sung. Psalms, hymns, worship songs, and other church music may be sung. Services can be varied for special events like significant Calendar of saints, feast days. Nearly all forms of worship incorporate the Eucharist, which consists of a meal. It is reenacted in accordance with Jesus' instruction at the Last Supper that his followers do in remembrance of him as when he gave his disciples Sacramental bread, bread, saying, "This is my body", and gave them sacramental wine, wine saying, "This is my blood". In the Early Christianity, early church, Christians and those yet to complete initiation would separate for the Eucharistic part of the service. Some denominations such as Confessional Lutheran churches continue to practice 'closed communion'. They offer communion to those who are already united in that denomination or sometimes individual church. Catholics further restrict participation to their members who are not in a state of mortal sin. Many other churches, such as Anglican Communion and United Methodist Church, practice 'open communion' since they view communion as a means to unity, rather than an end, and invite all believing Christians to participate.

Sacraments or ordinances

In Christian belief and practice, a ''sacrament'' is a Ritual, rite, instituted by Christ, that confers divine grace, grace, constituting a Sacred Mysteries, sacred mystery. The term is derived from the Latin word ''sacramentum'', which was used to translate the Greek word for ''mystery''. Views concerning both which rites are sacramental, and what it means for an act to be a sacrament, vary among Christian denominations and traditions.Cross/Livingstone. ''The Oxford Dictionary of the Christian Church''. pp. 1435ff. The most conventional functional definition of a sacrament is that it is an outward sign, instituted by Christ, that conveys an inward, spiritual grace through Christ. The two most widely accepted sacraments are Baptism and the Eucharist; however, the majority of Christians also recognize five additional sacraments: Confirmation (Christian sacrament), Confirmation (Chrismation in the Eastern tradition), Holy Orders (or

), Penance (or Confession (religion), Confession), Anointing of the Sick, and Matrimony (see Christian views on marriage). Taken together, these are the Sacraments of the Catholic Church, Seven Sacraments as recognized by churches in the High Church tradition—notably Sacraments of the Catholic Church, Catholic,

, Oriental Orthodox, Independent Catholic Churches, Independent Catholic, Old Catholic, many Anglican sacraments, Anglicans, and some Lutherans. Most other denominations and traditions typically affirm only Baptism and Eucharist as sacraments, while some Protestant groups, such as the Quakers, reject sacramental theology. Certain denominations of Christianity, such as Anabaptists, use the term "ordinance (Christianity), ordinances" to refer to rites instituted by Jesus for Christians to observe. Seven ordinances have been taught in many Conservative Mennonite, Conservative Mennonite Anabaptist churches, which include "baptism, communion, footwashing, marriage, anointing with oil, the holy kiss, and the prayer covering". In addition to this, the Church of the East has two additional sacraments in place of the traditional sacraments of Matrimony and the Anointing of the Sick. These include Holy Leaven (Melka) and the sign of the cross.''Holy Apostolic Catholic Assyrian Church of the East, Archdiocese of Australia, New Zealand and Lebanon.''

Liturgical calendar

Catholics, Eastern Christians, Lutherans, Anglicans and other traditional Protestant communities frame worship around the liturgical year. The liturgical cycle divides the year into a series of seasons, each with their theological emphases, and modes of prayer, which can be signified by different ways of decorating churches, colors of paraments and vestments for clergy, scriptural readings, themes for preaching and even different traditions and practices often observed personally or in the home. Western Christian liturgical calendars are based on the cycle of the Roman Rite of the Catholic Church, and Eastern Christians use analogous calendars based on the cycle of their respective Christian rite, rites. Calendars set aside holy days, such as Solemnity, solemnities which commemorate an event in the life of Jesus, Mary, or the saints, and periods of fasting, such as Lent and other pious events such as memoria, or lesser festivals commemorating saints. Christian groups that do not follow a liturgical tradition often retain certain celebrations, such as Christmas, Easter, and Pentecost: these are the celebrations of Christ's birth, resurrection, and the descent of the Holy Spirit upon the Church, respectively. A few denominations such as Quakers, Quaker Christians make no use of a liturgical calendar.

Symbols

Christianity has not generally practiced Aniconism in Christianity, aniconism, the avoidance or prohibition of devotional images, even if early

s and some modern Christian denomination, denominations, invoking the Ten Commandments, Decalogue's prohibition of idolatry, avoided figures in their symbols. The Christian cross, cross, today one of the most widely recognized symbols, was used by Christians from the earliest times. Tertullian, in his book ''De Corona'', tells how it was already a tradition for Christians to trace the sign of the cross on their foreheads. Although the cross was known to the early Christians, the crucifix did not appear in use until the 5th century.Dilasser. ''The Symbols of the Church''. Among the earliest Christian symbols, that of the fish or Ichthys seems to have ranked first in importance, as seen on monumental sources such as tombs from the first decades of the 2nd century. Its popularity seemingly arose from the Greek word ''ichthys'' (fish) forming an acrostic for the Greek phrase ''Iesous Christos Theou Yios Soter'' (Ἰησοῦς Χριστός, Θεοῦ Υἱός, Σωτήρ), (Jesus Christ, Son of God, Savior), a concise summary of Christian faith. Other major Christian symbols include the Chi-Rho, chi-rho monogram, the Dove of peace, dove and olive branch (symbolic of the Holy Spirit), the sacrificial lamb (representing Christ's sacrifice), the vine (symbolizing the connection of the Christian with Christ) and many others. These all derive from passages of the New Testament.

Baptism

Baptism is the ritual act, with the use of water, by which a person is admitted to membership of the

. Beliefs on baptism vary among denominations. Differences occur firstly on whether the act has any spiritual significance. Some, such as the Catholic and Eastern Orthodox churches, as well as Lutherans and Anglicans, hold to the doctrine of baptismal regeneration, which affirms that baptism creates or strengthens a person's faith, and is intimately linked to salvation. Baptists and Plymouth Brethren view baptism as a purely symbolic act, an external public declaration of the inward change which has taken place in the person, but not as spiritually efficacious. Secondly, there are differences of opinion on the methodology (or mode) of the act. These modes are: by Immersion baptism, ''immersion''; if immersion is total, by ''submersion''; by affusion (pouring); and by aspersion (sprinkling). Those who hold the first view may also adhere to the tradition of infant baptism; the Orthodox Churches all practice infant baptism and always baptize by total immersion repeated three times in the name of the Father, the Son, and the Holy Spirit. The Lutheran Church and the Catholic Church also practice infant baptism, usually by affusion, and utilizing the Trinitarian formula. Anabaptist Christians practice believer's baptism, in which an adult chooses to receive the ordinance after making a decision to follow Jesus. Anabaptist denominations such as the Mennonites, Amish and Hutterites use affusion, pouring as the mode to administer believer's baptism, whereas Anabaptists of the Schwarzenau Brethren and River Brethren traditions baptize by immersion baptism, immersion.

Prayer

In the Gospel of Saint Matthew, Jesus taught the

, which has been seen as a model for Christian prayer. The injunction for Christians to pray the Lord's prayer thrice daily was given in the ''Didache'' and came to be recited by Christians at 9 am, 12 pm, and 3 pm. In the second century ''Apostolic Tradition'', Hippolytus of Rome, Hippolytus instructed Christians to pray at fixed prayer times, seven fixed prayer times: "on rising, at the lighting of the evening lamp, at bedtime, at midnight" and "the third, sixth and ninth hours of the day, being hours associated with Christ's Passion". Prayer positions, including kneeling, standing, and prostrations have been used for these seven fixed prayer times since the days of the early Church. Breviary, Breviaries such as the Shehimo and Agpeya are used by Oriental Orthodox Christians to pray these canonical hours while facing in the direction of prayer, eastward direction of prayer. The ''Apostolic Tradition'' directed that the sign of the cross be used by Christians during the Minor exorcism in Christianity, minor exorcism of

, during ablution in Christianity, ablutions before praying at fixed prayer times, and in times of temptation. ''Intercessory prayer'' is prayer offered for the benefit of other people. There are many intercessory prayers recorded in the Bible, including prayers of the Apostle Peter on behalf of sick persons and by prophets of the Old Testament in favor of other people. In the Epistle of James, no distinction is made between the intercessory prayer offered by ordinary believers and the prominent Old Testament prophet Elijah. The effectiveness of prayer in Christianity derives from the power of God rather than the status of the one praying. The ancient church, in both Eastern Christianity, Eastern and Western Christianity, developed a tradition of asking for the intercession of saints, intercession of (deceased) saints, and this remains the practice of most

, Oriental Orthodox,

, and some Lutheran and Anglican churches. Apart from certain sectors within the latter two denominations, other Churches of the Protestant Reformation, however, rejected prayer to the saints, largely on the basis of the sole mediatorship of Christ. The reformer Huldrych Zwingli admitted that he had offered prayers to the saints until his reading of the Bible convinced him that this was idolatry in Christianity, idolatrous. According to the ''Catechism of the Catholic Church'': "Prayer is the raising of one's mind and heart to God or the requesting of good things from God". The ''Book of Common Prayer'' in the Anglican tradition is a guide which provides a set order for services, containing set prayers, scripture readings, and hymns or sung Psalms. Frequently in Western Christianity, when praying, the hands are placed palms together and forward as in the feudal commendation ceremony. At other times the older orans posture may be used, with palms up and elbows in.

Scriptures

Christianity, like other religions, has adherents whose beliefs and biblical interpretations vary. Christianity regards the biblical canon, the Old Testament and the

, as the Biblical inspiration, inspired word of God. The traditional view of inspiration is that God worked through human authors so that what they produced was what God wished to communicate. The Greek word referring to inspiration in is ''theopneustos'', which literally means "God-breathed". Some believe that divine inspiration makes present Bibles Biblical inerrancy, inerrant. Others claim inerrancy for the Bible in its original manuscripts, although none of those are extant. Still others maintain that only a particular translation is inerrant, such as the King James Version. Another closely related view is biblical infallibility or limited inerrancy, which affirms that the Bible is free of error as a guide to salvation, but may include errors on matters such as history, geography, or science. The canon of the Old Testament accepted by Protestant churches, which is only the Tanakh (the canon of the

Hebrew Bible The Hebrew Bible or Tanakh (;"Tanach"
'' In antiquity, two schools of exegesis developed in School of Alexandria, Alexandria and School of Antioch, Antioch. The Alexandrian interpretation, exemplified by

, tended to read Scripture allegory, allegorically, while the Antiochene interpretation adhered to the literal sense, holding that other meanings (called ''theoria'') could only be accepted if based on the literal meaning. Catholic theology distinguishes two senses of scripture: the literal and the spiritual. The ''literal'' sense of understanding scripture is the meaning conveyed by the words of Scripture. The ''spiritual'' sense is further subdivided into: * The ''allegorical'' sense, which includes Typology (theology), typology. An example would be the Passage of the Red Sea, parting of the Red Sea being understood as a "type" (sign) of baptism. * The ''moral'' sense, which understands the scripture to contain some ethical teaching. * The ''anagoge, anagogical'' sense, which applies to eschatology, eternity and the Apocalypse, consummation of the world. Regarding exegesis, following the rules of sound interpretation, Catholic theology holds: * The injunction that all other senses of sacred scripture are based on the ''literal'' * That the historicity of the Gospels must be absolutely and constantly held * That scripture must be read within the "living Tradition of the whole Church" and * That "the task of interpretation has been entrusted to the bishops in communion with the successor of Peter, the Bishop of diocese of Rome, Rome".

Protestant interpretation

Qualities of Scripture

Many Protestant Christians, such as Lutherans and the Reformed, believe in the doctrine of ''sola scriptura''—that the Bible is a self-sufficient revelation, the final authority on all Christian doctrine, and Revelation, revealed all truth necessary for salvation; other Protestant Christians, such as Methodists and Anglicans, affirm the doctrine of ''prima scriptura'' which teaches that Scripture is the primary source for Christian doctrine, but that "tradition, experience, and reason" can nurture the Christian religion as long as they are in harmony with the Bible. Protestants characteristically believe that ordinary believers may reach an adequate understanding of Scripture because Scripture itself is clear in its meaning (or "perspicuous"). Martin Luther believed that without God's help, Scripture would be "enveloped in darkness". He advocated for "one definite and simple understanding of Scripture". John Calvin wrote, "all who refuse not to follow the Holy Spirit as their guide, find in the Scripture a clear light". Related to this is "efficacy", that Scripture is able to lead people to faith; and "sufficiency", that the Scriptures contain everything that one needs to know in order to obtain salvation and to live a Christian life.

Original intended meaning of Scripture

Protestants stress the meaning conveyed by the words of Scripture, the historical-grammatical method. The historical-grammatical method or grammatico-historical method is an effort in Biblical hermeneutics to find the intended original meaning in the text. This original intended meaning of the text is drawn out through examination of the passage in light of the grammatical and syntactical aspects, the historical background, the literary genre, as well as theological (canonical) considerations. The historical-grammatical method distinguishes between the one original meaning and the significance of the text. The significance of the text includes the ensuing use of the text or application. The original passage is seen as having only a single meaning or sense. As Milton S. Terry said: "A fundamental principle in grammatico-historical exposition is that the words and sentences can have but one significance in one and the same connection. The moment we neglect this principle we drift out upon a sea of uncertainty and conjecture". Technically speaking, the grammatical-historical method of interpretation is distinct from the determination of the passage's significance in light of that interpretation. Taken together, both define the term (Biblical) hermeneutics. Some Protestant interpreters make use of Typology (theology), typology.

History

Early Christianity

Apostolic Age

PikiWiki Israel 73792 mount zion jerusalem

Christianity developed during the 1st century AD as a

sect with Hellenistic religion, Hellenistic influence of Second Temple Judaism. An early Jewish Christian community was founded in Jerusalem under the leadership of the Pillars of the Church, namely James the Just, the brother of Jesus, Saint Peter, Peter, and John. Jewish Christianity soon attracted Gentile God-fearers, posing a problem for its Jewish principles of faith, Jewish religious outlook, which insisted on close observance of the Jewish commandments. Paul the Apostle solved this by insisting that salvation by Pistis Christou, faith in Christ, and Participation in Christ, participation in his death and resurrection by their baptism, sufficed. At first he persecuted the early Christians, but after a conversion experience he preached to the gentiles, and is regarded as having had a formative effect on the emerging Christians, Christian identity as separate from Judaism. Eventually, his departure from Jewish customs would result in the establishment of Christianity as an independent religion.

Ante-Nicene period

This formative period was followed by the early bishops, whom Christians consider the apostolic succession, successors of Christ's apostles. From the year 150, Christian teachers began to produce theological and apologetic works aimed at defending the faith. These authors are known as the Church Fathers, and the study of them is called patristics. Notable early Fathers include

, Polycarp, Justin Martyr, Irenaeus,

, Clement of Alexandria and

. Persecution of Christians occurred intermittently and on a small scale by both Jewish and Persecution of early Christians by the Romans, Roman authorities, with Roman action starting at the time of the Great Fire of Rome in 64 AD. Examples of early executions under Jewish authority reported in the

). Yale University. when the edict of Decius in 250 AD required everyone in the Roman Empire (except Jews) to perform a sacrifice to the Roman gods. The Diocletianic Persecution beginning in 303 AD was also particularly severe. Roman persecution ended in 313 AD with the

. While Proto-orthodox Christianity was becoming dominant, heterodox sects also existed at the same time, which held radically different beliefs. Gnostic Christianity developed a duotheistic doctrine based on illusion and enlightenment rather than forgiveness of sin. With only a few scriptures overlapping with the developing orthodox canon, most Gnostic texts and Gnostic gospels were eventually considered heretical and suppressed by mainstream Christians. A gradual splitting off of Gentile Christianity left Jewish Christians continuing to follow the Law of Moses, including practices such as circumcision. By the fifth century, they and the Jewish–Christian gospels would be largely suppressed by the dominant sects in both Judaism and Christianity.

Spread and acceptance in Roman Empire

Christianity spread to Aramaic-speaking peoples along the Mediterranean coast and also to the inland parts of the

and beyond that into the Parthian Empire and the later Sasanian Empire, including

, which was dominated at different times and to varying extents by these empires. The presence of Christianity in Africa began in the middle of the 1st century in Egypt and by the end of the 2nd century in the region around Carthage. Mark the Evangelist is claimed to have started the Church of Alexandria in about 43 CE; various later churches claim this as their own legacy, including the Coptic Orthodox Church. Important Africans who influenced the early development of Christianity include

, Clement of Alexandria, Origen of Alexandria, Cyprian, Athanasius, and Augustine of Hippo. Kohrvirab

Tiridates III of Armenia, King Tiridates III made Christianity the state religion in Armenia between 301 and 314, thus Armenia became the first officially Christian state. It was not an entirely new religion in Armenia, having penetrated into the country from at least the third century, but it may have been present even earlier. Constantine the Great, Constantine I was exposed to Christianity in his youth, and throughout his life his support for the religion grew, culminating in baptism on his deathbed. During his reign, state-sanctioned persecution of Christians was ended with the Edict of Serdica, Edict of Toleration in 311 and the

in 313. At that point, Christianity was still a minority belief, comprising perhaps only five percent of the Roman population. Influenced by his adviser Mardonius (philosopher), Mardonius, Constantine's nephew Julian (emperor), Julian unsuccessfully tried to suppress Christianity. On 27 February 380, Theodosius I, Gratian, and Valentinian II established Nicene Christianity as the State church of the Roman Empire. As soon as it became connected to the state, Christianity grew wealthy; the Church solicited donations from the rich and could now own land. Constantine was also instrumental in the convocation of the First Council of Nicaea in 325, which sought to address Arianism and formulated the Nicene Creed, which is still used by in Catholicism, Eastern Orthodoxy,

, Anglicanism, and many other

churches. Nicaea was the first of a series of ecumenical councils, which formally defined critical elements of the theology of the Church, notably concerning

.McManners, ''Oxford Illustrated History of Christianity'', pp. 37ff. The Church of the East did not accept the third and following ecumenical councils and is still separate today by its successors (Assyrian Church of the East). In terms of prosperity and cultural life, the Byzantine Empire was one of the peaks in Christian history and Christian civilization,. and Constantinople remained the leading city of the Christian world in size, wealth, and culture. Greek scholars in the Renaissance, There was a renewed interest in classical Greek philosophy, as well as an increase in literary output in vernacular Greek.. Byzantine art and literature held a preeminent place in Europe, and the cultural impact of Byzantine art on the West during this period was enormous and of long-lasting significance.. The later rise of Islam in North Africa reduced the size and numbers of Christian congregations, leaving in large numbers only the Coptic Orthodox Church, Coptic Church in Egypt, the Ethiopian Orthodox Tewahedo Church in the Horn of Africa and the Christianity in Sudan, Nubian Church in the Sudan (Nobatia, Makuria and Alodia).

Middle Ages

Early Middle Ages

With the decline and Fall of the Western Roman Empire, fall of the Roman Empire in the West, the papacy became a political player, first visible in Pope Leo I, Pope Leo's diplomatic dealings with Attila the Hun, Huns and Vandals. The church also entered into a long period of missionary activity and expansion among the various tribes. While Arianism, Arianists instituted the death penalty for practicing pagans (see the Massacre of Verden, for example), what would later become Catholicism also spread among the Hungarians, the Germanic peoples, Germanic, the Celts, Celtic, the Baltic peoples, Baltic and some Slavic peoples. Around 500, St. Benedict set out Rule of Saint Benedict, his Monastic Rule, establishing a system of regulations for the foundation and running of monasteries. Monasticism became a powerful force throughout Europe, and gave rise to many early centers of learning, most famously in Ireland, Scotland, and Gaul, contributing to the Carolingian Renaissance of the 9th century. In the 7th century, Muslim conquest of Syria, Muslims conquered Syria (including Jerusalem), North Africa, and Spain, converting some of the Christian population to Islam, and placing the rest under a separate Dhimmi, legal status. Part of the Muslims' success was due to the exhaustion of the Byzantine Empire in its decades long conflict with Persia. Beginning in the 8th century, with the rise of Carolingian leaders, the Papacy sought greater political support in the Frankish Kingdom. The Middle Ages brought about major changes within the church. Pope Gregory the Great dramatically reformed the Ecclesiastical polity, ecclesiastical structure and administration. In the early 8th century, iconoclasm became a divisive issue, when it was sponsored by the Byzantium, Byzantine emperors. The Second Council of Nicaea, Second Ecumenical Council of Nicaea (787) finally pronounced in favor of icons. In the early 10th century, Western Christian monasticism was further rejuvenated through the leadership of the great Benedictine monastery of Cluny Abbey, Cluny.

High and Late Middle Ages

In the West, from the 11th century onward, some older cathedral schools Medieval university, became universities (see, for example, University of Oxford, University of Paris and University of Bologna). Previously, higher education had been the domain of Christian cathedral schools or monastic schools (''Scholae monasticae''), led by monks and nuns. Evidence of such schools dates back to the 6th century CE. These new universities expanded the curriculum to include academic programs for clerics, lawyers, civil servants, and physicians. The university is generally regarded as an institution that has its origin in the History of Christianity, Medieval Christian setting.Rüegg, Walter: "Foreword. The University as a European Institution", in: ''A History of the University in Europe. Vol. 1: Universities in the Middle Ages'', Cambridge University Press, 1992, , pp. XIX–XX Accompanying the rise of the "new towns" throughout Europe, mendicant orders were founded, bringing the Consecrated life (Catholic Church), consecrated religious life out of the monastery and into the new urban setting. The two principal mendicant movements were the Franciscans and the Dominican Order, Dominicans, founded by Francis of Assisi, St. Francis and St. Dominic, respectively. Both orders made significant contributions to the development of the great universities of Europe. Another new order was the Cistercians, whose large isolated monasteries spearheaded the settlement of former wilderness areas. In this period, church building and ecclesiastical architecture reached new heights, culminating in the orders of Romanesque architecture, Romanesque and Gothic architecture and the building of the great European cathedrals. Christian nationalism emerged during this era in which Christians felt the impulse to recover lands in which Christianity had historically flourished. From 1095 under the pontificate of Urban II, the First Crusade was launched. These were a series of military campaigns in the Holy Land and elsewhere, initiated in response to pleas from the Byzantine Emperor Alexios I for aid against Turkish people, Turkish expansion. The Crusades ultimately failed to stifle Islamic aggression and even contributed to Christian enmity with the sacking of Constantinople during the Fourth Crusade. The Christian Church experienced internal conflict between the 7th and 13th centuries that resulted in a East-West Schism, schism between the so-called Latin or

branch (the Catholic Church), and an Eastern Christianity, Eastern, largely Greek, branch (the

). The two sides disagreed on a number of administrative, liturgical and doctrinal issues, most prominently Eastern Orthodox opposition to papal supremacy.Duffy, ''Saints and Sinners'' (1997), p. 91 The Second Council of Lyon (1274) and the Council of Florence (1439) attempted to reunite the churches, but in both cases, the Eastern Orthodox refused to implement the decisions, and the two principal churches remain in schism to the present day. However, the Catholic Church has achieved union with various Eastern Catholic Churches, smaller eastern churches. In the thirteenth century, a new emphasis on Jesus' suffering, exemplified by the Franciscans' preaching, had the consequence of turning worshippers' attention towards Jews, on whom Jewish deicide, Christians had placed the blame for Jesus' death. Christianity's limited tolerance of Jews was not new—Augustine of Hippo said that Jews should not be allowed to enjoy the citizenship that Christians took for granted—but the growing antipathy towards Jews was a factor that led to Edict of Expulsion, the expulsion of Jews from England in 1290, the first of many such expulsions in Europe. Beginning around 1184, following the crusade against Cathars, Cathar heresy, various institutions, broadly referred to as the Inquisition, were established with the aim of suppressing heresy and securing religious and doctrinal unity within Christianity through religious conversion, conversion and prosecution.

Modern era

Protestant Reformation and Counter-Reformation

The 15th-century Renaissance brought about a renewed interest in ancient and classical learning. During the

, Martin Luther posted the ''Ninety-five Theses'' 1517 against the sale of indulgences.Simon. ''Great Ages of Man: The Reformation''. pp. 39, 55–61. Printed copies soon spread throughout Europe. In 1521 the Edict of Worms condemned and excommunicated Luther and his followers, resulting in the schism of the Western Christianity, Western Christendom into several branches.Simon. ''Great Ages of Man: The Reformation''. p. 7. Other reformers like Huldrych Zwingli, Zwingli, Johannes Oecolampadius, Oecolampadius, John Calvin, Calvin, John Knox, Knox, and Jacobus Arminius, Arminius further criticized Catholic teaching and worship. These challenges developed into the movement called

, which repudiated the papal primacy, primacy of the pope, the role of tradition, the Catholic sacraments, seven sacraments, and other doctrines and practices. The English Reformation, Reformation in England began in 1534, when Henry VIII of England, King Henry VIII had himself Act of Supremacy, declared head of the Church of England. Beginning in 1536, the monasteries throughout England, Wales and Ireland were Dissolution of the monasteries, dissolved.Schama. ''A History of Britain''. pp. 306–310. Thomas Müntzer, Andreas Karlstadt and other theologians perceived both the Catholic Church and the confessions of the Magisterial Reformation as corrupted. Their activity brought about the Radical Reformation, which gave birth to various Anabaptism, Anabaptist denominations. Michelangelo's Pieta 5450 cropncleaned edit

Partly in response to the Protestant Reformation, the Catholic Church engaged in a substantial process of reform and renewal, known as the Counter-Reformation or Catholic Reform. The Council of Trent clarified and reasserted Catholic doctrine. During the following centuries, competition between Catholicism and Protestantism became deeply entangled with political struggles among European states.Simon. ''Great Ages of Man: The Reformation''. pp. 109–120. Meanwhile, the discovery of America by Christopher Columbus in 1492 brought about a new wave of missionary activity. Partly from missionary zeal, but under the impetus of Colonialism, colonial expansion by the European powers, Christianity spread to the Americas, Oceania, East Asia and sub-Saharan Africa. Throughout Europe, the division caused by the Reformation led to outbreaks of religious violence and the establishment of separate state churches in Europe.

spread into the northern, central, and eastern parts of present-day Germany, Livonia, and Scandinavia. Anglicanism was established in England in 1534. Calvinism and its varieties, such as Presbyterianism, were introduced in Scotland, the Netherlands, Hungary, Switzerland, and France. Arminianism gained followers in the Netherlands and Frisia. Ultimately, these differences led to the outbreak of religious war, conflicts in which religion played a key factor. The Thirty Years' War, the English Civil War, and the French Wars of Religion are prominent examples. These events intensified the Christian debate on persecution and toleration. In the revival of neoplatonism Renaissance humanism, Renaissance humanists did not reject Christianity; quite the contrary, many of the greatest works of the Renaissance were devoted to it, and the Catholic Church patronized many works of Renaissance art.Open University,
Looking at the Renaissance: Religious Context in the Renaissance
' (Retrieved 10 May 2007) Much, if not most, of the new art was commissioned by or in dedication to the Church. Some scholars and historians attribute Christianity to having contributed to the rise of the Scientific Revolution. Many well-known historical figures who influenced Western science considered themselves Christian such as Nicolaus Copernicus, Galileo Galilei, Johannes Kepler, Isaac NewtonRichard S. Westfall – Indiana University and Robert Boyle.

Post-Enlightenment

In the era known as the Great Divergence, when in the West, the Age of Enlightenment and the scientific revolution brought about great societal changes, Christianity was confronted with various forms of skepticism and with certain modern Ideology, political ideologies, such as versions of socialism and liberalism. Events ranged from mere anti-clericalism to violent outbursts against Christianity, such as the dechristianisation of France during the French Revolution, dechristianization of France during the French Revolution, the Spanish Civil War, and certain Marxism, Marxist movements, especially Russian Revolution (1917), the Russian Revolution and the persecution of Christians in the Soviet Union under state atheism. Especially pressing in Europe was the formation of nation states after the Napoleonic era. In all European countries, different Christian denominations found themselves in competition to greater or lesser extents with each other and with the state. Variables were the relative sizes of the denominations and the religious, political, and ideological orientation of the states. Urs Altermatt of the University of Fribourg, looking specifically at Catholicism in Europe, identifies four models for the European nations. In traditionally Catholic-majority countries such as Belgium, Spain, and Austria, to some extent, religious and national communities are more or less identical. Cultural symbiosis and separation are found in Poland, the Republic of Ireland, and Switzerland, all countries with competing denominations. Competition is found in Germany, the Netherlands, and again Switzerland, all countries with minority Catholic populations, which to a greater or lesser extent identified with the nation. Finally, separation between religion (again, specifically Catholicism) and the state is found to a great degree in France and Italy, countries where the state actively opposed itself to the authority of the Catholic Church. The combined factors of the formation of nation states and ultramontanism, especially in Germany and the Netherlands, but also in England to a much lesser extent, often forced Catholic churches, organizations, and believers to choose between the national demands of the state and the authority of the Church, specifically the papacy. This conflict came to a head in the First Vatican Council, and in Germany would lead directly to the ''Kulturkampf'', where liberals and Protestants under the leadership of Otto von Bismarck, Bismarck managed to severely restrict Catholic expression and organization. Christian commitment in Europe dropped as modernity and secularism came into their own, particularly in the Czech Republic and Estonia, while religious commitments in America have been generally high in comparison to Europe. Changes in worldwide Christianity over the last century have been significant, since 1900, Christianity has spread rapidly in the Global South and Third World countries. The late 20th century has shown the shift of Christian adherence to the Third World and the Southern Hemisphere in general, with the West no longer the chief standard bearer of Christianity. Approximately 7 to 10% of Arabs are Arab Christians and Arabic-speaking Christians, Christians, most prevalent in Egypt, Syria and Lebanon.

Demographics

With around 2.38 billion adherents according to a 2020 estimation by Pew Research Center,31.4% of ≈7.4 billion world population (under the section 'People') split into three main branches of Catholic, Protestant, and Eastern Orthodox, Christianity is the major religious groups, world's largest religion. High birth rates and Conversion to Christianity, conversions in the global South were cited as the reasons for the Christian population growth. The Christian share of the world's population has stood at around 33% for the last hundred years, which means that one in three persons on Earth are Christians. This masks a major shift in the demographics of Christianity; large increases in the developing world have been accompanied by substantial declines in the developed world, mainly in Western Europe and North America. According to a 2015 Pew Research Center study, within the next four decades, Christianity will remain the largest religion; and by 2050, the Christian population is expected to exceed 3 billion.

According to some scholars, Christianity ranks at first place in net gains through religious conversion. As a percentage of Christians, the

and Orthodoxy (both Eastern Orthodox Church, Eastern and Oriental Orthodoxy, Oriental) are declining in some parts of the world (though Catholicism is growing in Asia, in Africa, vibrant in Eastern Europe, etc.), while Protestants and other Christians are on the rise in the developing world. The so-called ''popular Protestantism''A flexible term, defined as all forms of Protestantism with the notable exception of the historical denominations deriving directly from the Protestant Reformation. is one of the fastest growing religious categories in the world. Nevertheless, Catholicism will also continue to grow to 1.63 billion by 2050, according to Todd Johnson of the Center for the Study of Global Christianity. Africa alone, by 2015, will be home to 230 million African Catholics. And if in 2018, the U.N. projects that Africa's population will reach 4.5 billion by 2100 (not 2 billion as predicted in 2004), Catholicism will indeed grow, as will other religious groups. According to Pew Research Center, Africa is expected to be home to 1.1 billion Christianity in Africa, African Christians by 2050. In 2010, 87% of the world's Christian population lived in countries where Christians are in the majority, while 13% of the world's Christian population lived in countries where Christians are in the minority. Christianity is the predominant religion in Europe, the Americas, Oceania, and Sub-Saharan Africa. There are also large Christian communities in other parts of the world, such as Central Asia, the Middle East and North Africa,

, Southeast Asia, and the Indian subcontinent. In Asia, it is the dominant religion in Armenia, Cyprus, Georgia, East Timor, and the Philippines. However, it is declining in some areas including the northern and western United States, some areas in Oceania (Australia and New ZealandTable 28, 2006 Census Data – QuickStats About Culture and Identity – Tables
), northern Europe (including Great Britain, Scandinavia and other places), France, Germany, and the Canadian provinces of Ontario, British Columbia, and Quebec, and some parts of Asia (especially the Middle East, due to the Christian emigration, and Macau). The Christian population is not decreasing in Brazil, the southern United States, and the province of Alberta, Canada, but the percentage is decreasing. Since the fall of communism, the proportion of Christians has been stable or even increased in the Central Europe, Central and Eastern European countries. Christianity is growing rapidly in both numbers and percentage in China, other Asian countries, Sub-Saharan Africa,The Next Christendom: The Rise of Global Christianity. New York: Oxford University Press. 2002. 270 pp. Latin America, Eastern Europe,

(Maghreb), Gulf Cooperation Council countries, and Oceania. Despite a decline in adherence in the

, Christianity remains the dominant religion in the region, with about 70% of that population identifying as Christian. Christianity remains the largest religion in Western Europe, where 71% of Western Europeans identified themselves as Christian in 2018. A 2011 Pew Research Center survey found that 76% of Europeans, 73% in Oceania and about 86% in the Americas (90% in Latin America and 77% in North America) identified themselves as Christians. By 2010 about 157 countries and territories in the world had Christianity by country, Christian majorities. However, there are many charismatic movements that have become well established over large parts of the world, especially Africa, Latin America, and Asia. Since 1900, primarily due to conversion, Protestantism has spread rapidly in Africa, Asia, Oceania, and Latin America. From 1960 to 2000, the global growth of the number of reported

grew three times the world's population rate, and twice that of Islam. According to the historian Geoffrey Blainey from the University of Melbourne, since the 1960s there has been a substantial increase in the number of conversions from Islam to Christianity, mostly to the Evangelical and Pentecostal forms. A study conducted by St. Mary's University estimated about 10.2 million Muslim convert to Christianity, converts to Christianity in 2015; according to the study significant numbers of Muslim converts to Christianity can be found in Afghanistan, Azerbaijan, Central Asia (including Kazakhstan, Kyrgyzstan, and other countries), Indonesia, Malaysia, the Middle East (including Iran, Saudi Arabia, Turkey, and other countries), North Africa (including Algeria, Morocco, and TunisiaInternational Religious Freedom Report 2007: Tunisia
United States Bureau of Democracy, Human Rights and Labor (14 September 2007). ''This article incorporates text from this source, which is in the public domain.''), Sub-Saharan Africa, and the Western World (including Albania, Belgium, France, Germany, Kosovo, the Netherlands, Russia, Scandinavia, United Kingdom, the United States, and other western countries). It is also reported that Christianity is popular among people of different backgrounds in Africa and Asia; according to a report by the Singapore Management University, more people in Southeast Asia are converting to Christianity, many of them young and having a university degree. According to scholar Juliette Koning and Heidi Dahles of Vrije Universiteit Amsterdam there is a "rapid expansion" of Christianity in Singapore, China, Hong Kong, Taiwan, Christianity in Indonesia, Indonesia, Malaysia, and South Korea. According to scholar Terence Chong from the Institute of Southeast Asian Studies, since the 1980s Christianity is expanding in China, Singapore, Indonesia, Christianity in Japan, Japan, Malaysia, Taiwan, South Korea, and Vietnam. In most countries in the developed world, church attendance among people who continue to identify themselves as Christians has been falling over the last few decades. Some sources view this as part of a drift away from traditional membership institutions, while others link it to signs of a decline in belief in the importance of religion in general. Europe's Christian population, though in decline, still constitutes the largest geographical component of the religion. According to data from the 2012 European Social Survey, around a third of Christianity in Europe, European Christians say they attend services once a month or more. Conversely, according to the World Values Survey, about more than two-thirds of Latin American Christians, and about 90% of Christianity in Africa, African Christians (in Ghana, Nigeria, Rwanda, South Africa and Zimbabwe) said they attended church regularly. According to a 2018 study by the Pew Research Center, Christians in Africa and Latin America and the United States have high levels of commitment to their faith. Christian state, Christianity, in one form or another, is the sole state religion of the following nations: Argentina (Catholic), Costa Rica (Catholic), the Kingdom of Denmark (Lutheran), England (Anglican), Greece (Greek Orthodox), Iceland (Lutheran), Liechtenstein (Catholic), Malta (Catholic), Monaco (Catholic), Norway (Lutheran),Løsere bånd, men fortsatt statskirke
, ABC Nyheter Samoa, Tonga (Methodist), Tuvalu (Reformed), and Vatican City (Catholic). There are numerous other countries, such as Cyprus, which although do not have an established church, still give official recognition and support to a specific Christian denomination.

Churches and denominations

Christianity can be taxonomically divided into six main groups: Catholic Church, Roman Catholicism,

, Oriental Orthodox Churches, Oriental Orthodoxy, Eastern Orthodox Church, Eastern Orthodoxy, the Church of the East, and Restorationism. A broader distinction that is sometimes drawn is between Eastern Christianity and Western Christianity, which has its origins in the East–West Schism (Great Schism) of the 11th century. Recently, neither Western or Eastern World Christianity has also stood out, for example, in African-initiated churches. However, there are other present and historical Christian groups that do not fit neatly into one of these primary categories. There is a diversity of doctrines and Liturgy, liturgical practices among groups calling themselves Christian. These groups may vary ecclesiology, ecclesiologically in their views on a classification of Christian denominations. The Nicene Creed (325), however, is typically accepted as authoritative by most Christians, including the Catholic, Eastern Orthodox, Oriental Orthodox, and major Protestant (such as Lutheran and Anglican) denominations.

Catholic Church

Eastern Orthodox Church

The Eastern Orthodox Church consists of those churches in communion with the patriarchal sees of the East, such as the Ecumenical Patriarch of Constantinople.Cross/Livingstone. ''The Oxford Dictionary of the Christian Church'', p. 1199. Like the Catholic Church, the Eastern Orthodox Church also traces its heritage to the foundation of Christianity through apostolic succession and has an Episcopal polity, episcopal structure, though the autocephaly, autonomy of its component parts is emphasized, and most of them are national churches. Eastern Orthodox theology is based on holy tradition which incorporates the dogmatic decrees of the First seven ecumenical councils, seven Ecumenical Councils, the Scriptures, and the teaching of the Church Fathers. The church teaches that it is the Four Marks of the Church, one, holy, catholic and apostolic One true church, church established by Jesus in Christianity, Jesus Christ in his Great Commission, and that its bishops are the successors of Christ's apostles. It maintains that it practises the original Christian faith, as passed down by holy tradition. Its patriarchates, reminiscent of the pentarchy, and other autocephalous and autonomous churches reflect a variety of hierarchical Eastern Orthodox Church organization, organisation. It recognises seven major sacraments, of which the

is the principal one, celebrated Divine Liturgy, liturgically in synaxis. The church teaches that through Consecration#Eucharist, consecration epiclesis, invoked by a Priesthood (Orthodox Church), priest, the sacrificial bread and wine become the body and blood of Christ. The Mary, mother of Jesus, Virgin Mary is veneration, venerated in the Eastern Orthodox Church as the Theotokos, God-bearer, honoured in Marian devotions, devotions. Eastern Orthodoxy is the second largest single denomination in Christianity, with an estimated 230 million adherents, although Protestantism, Protestants collectively outnumber them, substantially. As one of the oldest surviving religious institutions in the world, the

has played a prominent role in the history and culture of Eastern Europe, Eastern and Southeastern Europe, the Caucasus, and the Near East. The majority of Eastern Orthodox Christians live mainly in Southeast Europe, Southeast and Eastern Europe, Cyprus, Georgia (country), Georgia, and parts of the Caucasus region, Siberia, and the Russian Far East. Over half of Eastern Orthodox Christians follow the Russian Orthodox Church, while the vast majority live within Russia. There are also communities in the former Byzantine Empire, Byzantine regions of Africa, the Eastern Mediterranean, and in the

. Eastern Orthodox communities are also present in many other parts of the world, particularly North America, Western Europe, and Australia, formed through diaspora, Conversion to Christianity, conversions, and missionary activity.

Oriental Orthodoxy

Addis abeba, chiesa della trinità, esterno 02

The Oriental Orthodoxy, Oriental Orthodox Churches (also called "Old Oriental" churches) are those eastern churches that recognize the first three ecumenical councils—

, and First Council of Ephesus, Ephesus—but reject the dogmatic definitions of the

and instead espouse a Miaphysite christology. The Oriental Orthodox communion consists of six groups: Syriac Orthodox, Coptic Orthodox Church, Coptic Orthodox, Ethiopian Orthodox, Eritrean Orthodox, Malankara Orthodox Syrian Church (India), and Armenian Apostolic churches. These six churches, while being in communion with each other, are completely independent hierarchically. These churches are generally not in communion with the

, with whom they are in dialogue for erecting a communion. Together, they have about 62 million members worldwide. As some of the oldest religious institutions in the world, the Oriental Orthodox Churches have played a prominent role in the history and culture of Armenia,

, Turkey, Eritrea,

, Christian Nubia, Sudan and parts of the

and India. An Eastern Christian body of Autocephaly, autocephalous Christian denomination, churches, its bishops are equal by virtue of episcopal ordination, and its doctrines can be summarized in that the churches recognize the validity of only the first three ecumenical councils. Some Oriental Orthodox Churches such as the Coptic Orthodox Church, Coptic Orthodox, Ethiopian Orthodox, Eritrean Orthodox, places a heavier emphasis on Old Testament teachings than one might find in other Christian denominations, and its followers adhere to certain practices: following Christian dietary laws, dietary rules that are similar to Jewish Kashrut, require that their male members undergo circumcision, and observes ritual purification.

Assyrian Church of the East

The Church of the East, which was part of the

, shared communion (Christian), communion with those in the

until the Council of Ephesus Nestorian schism, condemned Nestorius in 431. Continuing as a ''dhimmi'' community under the Rashidun Caliphate, Sunni Caliphate after the Muslim conquest of Persia (633–654), the Church of the East played a major role in the history of Christianity in Asia. Between the 9th and 14th centuries, it represented the world's largest Christian denomination in terms of geographical extent. It established Dioceses of the Church of the East to 1318, dioceses and communities stretching from the Mediterranean Sea and today's Iraq and Iran, to India (East Syriac ecclesiastical province), India (the Saint Thomas Christians, Saint Thomas Syrian Christians of Kerala), the Christianity among the Mongols, Mongol kingdoms in Central Asia, and Church of the East in China, China during the Tang dynasty (7th–9th centuries). In the 13th and 14th centuries, the church experienced a final period of expansion under the Mongol Empire, where influential Church of the East clergy sat in the Mongol court. The Assyrian Church of the East, with an unbroken patriarchate established in the 17th century, is an independent Eastern Christian denomination which claims continuity from the Church of the East—in parallel to the Catholic patriarchate established in the 16th century that evolved into the Chaldean Catholic Church, an Eastern Catholic church in full communion with the Pope. It is an Eastern Christian Christian denomination, church that follows the traditional christology and

of the historical Church of the East. Largely Aniconism in Christianity, aniconic and not in communion (Christianity), communion with any other church, it belongs to the eastern branch of Syriac Christianity, and uses the East Syriac Rite in its liturgy. Its main spoken language is Syriac language, Syriac, a dialect of Eastern Aramaic, and the majority of its adherents are ethnic Assyrian people, Assyrians, mostly living in Iran, Iraq, Syria, Turkey, India (Chaldean Syrian Church), and in the Assyrian diaspora. It is officially headquartered in the city of Erbil in northern Iraqi Kurdistan, and its original area also spreads into south-eastern Turkey and north-western Iran, corresponding to ancient Assyria. Its hierarchy is composed of metropolitan bishops and diocesan bishops, while lower clergy consists of priests and deacons, who serve in dioceses (eparchies) and parishes throughout the Middle East, India, North America, Oceania, and Europe (including the Caucasus and Russia). The Ancient Church of the East distinguished itself from the Assyrian Church of the East in 1964. It is one of the Assyrian people, Assyrian churches that claim continuity with the historical Church of the East, one of the oldest Christian churches in Mesopotamia. It is officially headquartered in the city of Baghdad, Iraq. The majority of its adherents are ethnic Assyrian people, Assyrians.

Protestantism

In 1521, the Edict of Worms condemned Martin Luther and officially banned citizens of the Holy Roman Empire from defending or propagating his ideas.Fahlbusch, Erwin, and Bromiley, Geoffrey William, ''The Encyclopedia of Christianity, Volume 3''. Grand Rapids, Michigan: Eerdmans, 2003. p. 362. This split within the Roman Catholic church is now called the

. Prominent Reformers included Martin Luther, Huldrych Zwingli, and John Calvin. The 1529 Protestation at Speyer against being excommunicated gave this party the name

. Luther's primary theological heirs are known as Lutheranism, Lutherans. Zwingli and Calvin's heirs are far broader denominationally, and are referred to as the Calvinism, Reformed tradition.McManners, ''Oxford Illustrated History of Christianity''. pp. 251–259. Protestants have developed Protestant culture, their own culture, with major contributions in education, the Merton thesis, humanities and sciences, the political and social order, the Protestant work ethic, economy and the arts, and many other fields.Karl Heussi, ''Kompendium der Kirchengeschichte'', 11. Auflage (1956), Tübingen (Germany), pp. 317–319, 325–326 The Anglicanism, Anglican churches descended from the Church of England and organized in the Anglican Communion. Some, but not all Anglicans consider themselves both Protestant and Catholic. Since the Anglican, Lutheran, and the Reformed branches of Protestantism originated for the most part in cooperation with the government, these movements are termed the "Magisterial Reformation". On the other hand, groups such as the Anabaptism, Anabaptists, who often do not consider themselves to be Protestant, originated in the Radical Reformation, which though sometimes protected under ''Acts of Toleration'', do not trace their history back to any state church. They are further distinguished by their rejection of infant baptism; they believe in baptism only of adult believers—credobaptism (Anabaptists include the Amish, Apostolic Christian Church, Apostolic, Mennonites, Hutterites, River Brethren and Schwarzenau Brethren/German Baptist groups.) The term ''Protestant'' also refers to any churches which formed later, with either the Magisterial or Radical traditions. In the 18th century, for example, Methodism grew out of Anglican minister John Wesley's Evangelical Revival, evangelical revival movement. Several Pentecostal and Nondenominational Christianity, non-denominational churches, which emphasize the cleansing power of the Holy Spirit, in turn grew out of Methodism. Because Methodists, Pentecostals and other evangelicals stress "accepting Jesus as your personal Lord and Savior", which comes from Wesley's emphasis of the Born again (Christianity), New Birth, they often refer to themselves as being Born again Christianity, born-again. Protestantism is the second largest major group of Christians after Catholicism by number of followers, although the Eastern Orthodox Church is larger than any single Protestant denomination. Estimates vary, mainly over the question of which denominations to classify as Protestant. Yet, the total number of Protestant Christians is generally estimated between 800 million and 1 billion, corresponding to nearly 40% of the world's Christians. The majority of Protestants are members of just a handful of denominational families, i.e. Adventism, Adventists, Anglicanism, Anglicans, Baptists, Calvinism, Reformed (Calvinists), Lutheranism, Lutherans, Methodists, Moravian Church, Moravians/Hussite Church, Hussites, and Pentecostalism, Pentecostals. Nondenominational Christianity, Nondenominational, Evangelicalism, evangelical, Charismatic Movement, charismatic, Neo-charismatic churches, neo-charismatic, independent, and other churches are on the rise, and constitute a significant part of Protestant Christianity. Some groups of individuals who hold basic Protestant tenets identify themselves as "Christians" or "born-again Christians". They typically distance themselves from the confessionalism (religion), confessionalism and creedalism of other Christian communitiesConfessionalism is a term employed by historians to refer to "the creation of fixed identities and systems of beliefs for separate churches which had previously been more fluid in their self-understanding, and which had not begun by seeking separate identities for themselves—they had wanted to be truly Catholic and reformed." (MacCulloch, ''The Reformation: A History'', p. xxiv.) by calling themselves "Non-denominational Christianity, non-denominational" or "evangelical". Often founded by individual pastors, they have little affiliation with historic denominations.

Restorationism

The

, a period of religious revival that occurred in the United States during the early 1800s, saw the development of a number of unrelated churches. They generally saw themselves as Restorationism, restoring the original church of Jesus Christ rather than reforming one of the existing churches. A common belief held by Restorationists was that the other divisions of Christianity had introduced doctrinal defects into Christianity, which was known as the Great Apostasy. In Asia, Iglesia ni Cristo is a known restorationist religion that was established during the early 1900s. Some of the churches originating during this period are historically connected to early 19th-century camp meetings in the Midwest and upstate New York. One of the largest churches produced from the movement is the Church of Jesus Christ of Latter-day Saints. American Millennialism and Adventism, which arose from Evangelical Protestantism, influenced the Jehovah's Witnesses movement and, as a reaction specifically to William Miller (preacher), William Miller, the Seventh-day Adventist Church, Seventh-day Adventists. Others, including the

, Churches of Christ, and the Christian churches and churches of Christ, have their roots in the contemporaneous Stone-Campbell

, which was centered in Kentucky and Tennessee. Other groups originating in this time period include the Christadelphians and the previously mentioned Latter Day Saints movement. While the churches originating in the Second Great Awakening have some superficial similarities, their doctrine and practices vary significantly.

Other

Within Italy, Poland, Lithuania, Transylvania, Hungary, Romania, and the United Kingdom, Unitarianism, Unitarian Churches emerged from the Reformed tradition, Reformed tradition in the 16th century; the Unitarian Church of Transylvania is an example of such a denomination that arose in this era. They adopted the Anabaptist doctrine of credobaptism. Various smaller Independent Catholic communities, such as the Old Catholic Church, include the word ''Catholic (term), Catholic'' in their title, and arguably have more or less liturgical practices in common with the Catholic Church, but are no longer in full communion with the Holy See. Spiritual Christians, such as the Doukhobors and Molokans, broke from the Russian Orthodox Church and maintain close association with Mennonites and Quakers due to similar religious practices; all of these groups are furthermore collectively considered to be peace churches due to their belief in Christian pacifism, pacifism. Messianic Judaism (or the Messianic Movement) is the name of a Christian movement comprising a number of streams, whose members may consider themselves Jewish. The movement originated in the 1960s and 1970s, and it blends elements of religious Jewish practice with evangelical Christianity. Messianic Judaism affirms Christian creeds such as the messiahship and divinity of "Yeshua" (the Hebrew name of Jesus) and the Triune Nature of God, while also adhering to some Jewish dietary laws and customs. Esoteric Christianity, Esoteric Christians, such as The Christian Community, regard Christianity as a Western esotericism, mystery religion and profess the existence and possession of certain Esotericism, esoteric doctrines or practices, hidden from the public and accessible only to a narrow circle of "enlightened", "initiated", or highly educated people. Nondenominational Christianity or non-denominational Christianity consists of Simple church, churches which typically distance themselves from the confessionalism (religion), confessionalism or creedalism of other Christian communities by not formally aligning with a specific Christian denomination. Nondenominational Christianity first arose in the 18th century through the Stone-Campbell Restoration Movement, with followers organizing themselves as "Christians (Stone Movement), Christians" and "Disciples of Christ (Campbell Movement), Disciples of Christ", but many typically adhere to evangelical Christianity.

Cultural influence

The history of the

spans about 1,700 years and includes a variety of socio-political developments, as well as advances in the Christian art, arts, Architecture of cathedrals and great churches, architecture, Christian literature, literature, Christianity and science, science, Christian philosophy, philosophy, and technology. Since the spread of Christianity from the

and

during the early

, Christendom has been divided in the pre-existing Greek East and Latin West. Consequently, different versions of the Christian cultures arose with their own rites and practices, centred around the cities of Rome (Western Christianity) and Archdiocese of Carthage, Carthage, whose communities were called Western or Latin Christendom, and Constantinople (Eastern Christianity), Antioch (Syriac Christianity), Kerala (Saint Thomas Christians, Indian Christianity) and Alexandria (Coptic Christianity), whose communities were called Eastern or Oriental Christendom. The Byzantine Empire was one of the peaks in Christian history and Eastern Christian civilization. From the 11th to 13th centuries, Latin Christendom rose to the central role of the Western world. The

has had a profound influence on Western civilization and on cultures around the globe; it has contributed to the formation of Western law, Western art, art, Western literature, texts, and education. With a literary tradition spanning two millennia, the Bible is one of the most influential works ever written. From practices of personal hygiene to philosophy and ethics, the Bible has directly and indirectly influenced politics and law, war and peace, sexual morals, marriage and family life, Hygiene in Christianity, toilet etiquette, letters and learning, the arts, economics, social justice, medical care and more. Lists of Christians, Christians have made a myriad of contributions to Progress (history), human progress in a broad and diverse range of fields, including philosophy, List of Christians in science and technology, science and technology, Catholic Church and health care, medicine, List of Catholic Church artists, fine arts and architecture, Christianity and politics, politics, List of Catholic authors, literatures, Christian music, music, and business. According to ''100 Years of Nobel Prizes'' a review of the Nobel Prizes award between 1901 and 2000 reveals that (65.4%) of Nobel Prizes Laureates, List of Christian Nobel laureates, have identified Christianity in its various forms as their religious preference.Baruch A. Shalev, ''100 Years of Nobel Prizes'' (2003), Atlantic Publishers & Distributors, p. 57: between 1901 and 2000 reveals that 654 Laureates belong to 28 different religions. Most (65.4%) have identified Christianity in its various forms as their religious preference. Outside the Western world, Christianity has had an influence on various cultures, such as in Africa, the Near East, Middle East, East Asia, Southeast Asia, and the Indian subcontinent. List of Christian scientists and scholars of the medieval Islamic world, Eastern Christian scientists and scholars of the medieval Islamic world (particularly Syriac Orthodox Church, Jacobite and Nestorianism, Nestorian Christians) contributed to the Arab Islamic Golden Age, Islamic civilization during the reign of the Umayyad and the Abbasids, Abbasid, by translating works of Greek philosophers to Syriac language, Syriac and afterwards, to Arabic language, Arabic. They also excelled in philosophy, science, theology, and medicine. Scholars and intellectuals agree Christians in the Middle East have made significant contributions to Arab and Islamic civilization since the introduction of Islam, and they have had a significant impact contributing the culture of the Mashriq, Turkey, and Iran.

Influence on Western culture

Western culture, throughout most of its history, has been nearly equivalent to Christian culture, and a large portion of the population of the Western Hemisphere can be described as practicing or nominal Christians. The notion of "Europe" and the "Western World" has been intimately connected with the concept of "Christianity and

". Many historians even attribute Christianity for being the link that created a unified European identity. Though Western culture contained several polytheistic religions during its early years under the Ancient Greece, Greek and Roman Empire, Roman empires, as the centralized Roman power waned, the dominance of the Catholic Church was the only consistent force in Western Europe. Until the Age of Enlightenment, Christian culture guided the course of philosophy, literature, art, music and science. Christian disciplines of the respective arts have subsequently developed into Christian philosophy, Christian art, Christian music, Christian literature, and so on. Christianity has had a significant impact on education, as the church created the bases of the Western system of education, and was the sponsor of Medieval university, founding universities in the Western world, as the university is generally regarded as an institution that has its origin in the History of Christianity, Medieval Christian setting. Historically, Christianity has often been a patron of science and medicine; many List of Catholic cleric-scientists, Catholic clergy, List of Jesuit scientists, Jesuits in particular, have been active in the sciences throughout history and have made significant contributions to the Christianity and science, development of science. Some scholars state that Christianity contributed to the rise of the Scientific Revolution. Protestantism also has had an important influence on science. According to the Merton Thesis, there was a positive correlation between the rise of English Puritanism and German Pietism on the one hand, and early experimental science on the other. The civilizing influence of Christianity includes social welfare, contribution to the medical and health care, founding hospitals, economics (as the Protestant work ethic), architecture,Sir Banister Fletcher, ''History of Architecture on the Comparative Method''. politics, literature, Hygiene in Christianity, personal hygiene (Ablution in Christianity, ablution), and family life. Historically, ''Extended family, extended families'' were the basic family unit in the Christian culture and Christian countries, countries. Cultural Christians are secular people with a Christian heritage who may not believe in the religious claims of Christianity, but who retain an affinity for the popular culture, art, Christian music, music, and so on related to the religion. ''Postchristianity'' is the term for the decline of Christianity, particularly in Christianity in Europe, Europe, Religion in Canada, Canada, Christianity in Australia, Australia, and to a minor degree the Southern Cone, in the 20th and 21st centuries, considered in terms of postmodernism. It refers to the loss of Christianity's monopoly on values and world view in historically Christian societies.

Ecumenism

Christian groups and List of Christian denominations, denominations have long expressed ideals of being reconciled, and in the 20th century, Christian ecumenism advanced in two ways.McManners, ''Oxford Illustrated History of Christianity'', pp. 581–584. One way was greater cooperation between groups, such as the World Evangelical Alliance founded in 1846 in London or the Edinburgh Missionary Conference of Protestants in 1910, the Justice, Peace and Creation Commission of the

founded in 1948 by Protestant and Orthodox churches, and similar national councils like the National Council of Churches in Australia, which includes Catholics. The other way was an institutional union with United and uniting churches, united churches, a practice that can be traced back to unions between Lutherans and Calvinists in early 19th-century Germany. Congregationalist, Methodist, and Presbyterian churches united in 1925 to form the United Church of Canada, and in 1977 to form the Uniting Church in Australia. The Church of South India was formed in 1947 by the union of Anglican, Baptist, Methodist, Congregationalist, and Presbyterian churches. The Christian Flag is an ecumenical flag designed in the early 20th century to represent all of Christianity and

. The ecumenical, monasticism, monastic Taizé Community is notable for being composed of more than one hundred monk, brothers from Protestant and Catholic traditions. The community emphasizes the reconciliation of all denominations and its main church, located in Taizé, Saône-et-Loire, France, is named the "Church of Reconciliation". The community is internationally known, attracting over 100,000 young Christian pilgrimage, pilgrims annually. Steps towards reconciliation on a global level were taken in 1965 by the Catholic and Orthodox churches, mutually revoking the excommunications that marked their East-West Schism, Great Schism in 1054; the Anglican Catholic International Commission (ARCIC) working towards full communion between those churches since 1970; and some Lutheran World Federation, Lutheran and Catholic churches signing the Joint Declaration on the Doctrine of Justification in 1999 to address conflicts at the root of the Protestant Reformation. In 2006, the World Methodist Council, representing all Methodist denominations, adopted the declaration.

Criticism, persecution, and apologetics

Criticism

Criticism of Christianity and Christians goes back to the Apostolic Age, with the New Testament recording friction between the followers of Jesus and the Pharisees and scribes (e.g. and ). In the 2nd century, Christianity was criticized by the Jews on various grounds, e.g. that the prophecies of the Hebrew Bible could not have been fulfilled by Jesus, given that he did not have a successful life. Additionally, a sacrifice to remove sins in advance, for everyone or as a human being, did not fit to the Jewish sacrifice ritual; furthermore, God in Judaism is said to judge people on their deeds instead of their beliefs. One of the first comprehensive attacks on Christianity came from the Greek philosopher Celsus, who wrote ''The True Word'', a polemic criticizing Christians as being unprofitable members of society. In response, the church father

published his treatise ''Contra Celsum'', or ''Against Celsus'', a seminal work of Christian apologetics, which systematically addressed Celsus's criticisms and helped bring Christianity a level of academic respectability. By the 3rd century, criticism of Christianity had mounted. Wild rumors about Christians were widely circulated, claiming that they were atheism, atheists and that, as part of their rituals, they devoured human infants and engaged in incestuous orgies. The Neoplatonism, Neoplatonist philosopher Porphyry (philosopher), Porphyry wrote the fifteen-volume ''Adversus Christianos'' as a comprehensive attack on Christianity, in part building on the teachings of Plotinus. By the 12th century, the Mishneh Torah (i.e., Rabbi Moses Maimonides) was criticizing Christianity on the grounds of idol worship, in that Christians attributed divinity to Jesus, who had a physical body. In the 19th century, Nietzsche began to write a series of polemics on the "unnatural" teachings of Christianity (e.g. sexual abstinence), and continued his criticism of Christianity to the end of his life. In the 20th century, the philosopher Bertrand Russell expressed his criticism of Christianity in ''Why I Am Not a Christian'', formulating his rejection of Christianity in the setting of logical arguments. Criticism of Christianity continues to date, e.g. Jewish and Muslim theologians criticize the doctrine of the

held by most Christians, stating that this doctrine in effect assumes that there are three gods, running against the basic tenet of monotheism. New Testament scholar Robert M. Price has outlined the possibility that some Bible stories are based partly on myth in ''The Christ Myth Theory and its problems''.

Persecution

Christians are one of the most Persecution of Christians, persecuted religious group in the world, especially in the Christianity in the Middle East, Middle-East,

and South and East Asia. In 2017, Open Doors estimated approximately 260 million Christians are subjected annually to "high, very high, or extreme persecution"Weber, Jeremy. "'Worst year yet’: the top 50 countries where it's hardest to be a Christian".

Apologetics

Christian apologetics aims to present a reason, rational basis for Christianity. The word "apologetic" (Greek: ἀπολογητικός ''apologētikos'') comes from the Greek verb ἀπολογέομαι ''apologeomai'', meaning "(I) speak in defense of". Christian apologetics has taken many forms over the centuries, starting with Paul the Apostle. The philosopher

presented five arguments for God's existence in the ''Summa Theologica'', while his ''Summa contra Gentiles'' was a major apologetic work. Another famous apologist, G. K. Chesterton, wrote in the early twentieth century about the benefits of religion and, specifically, Christianity. Famous for his use of paradox, Chesterton explained that while Christianity had the most mysteries, it was the most practical religion. He pointed to the Role of the Christian Church in civilization, advance of Christian civilizations as proof of its practicality. The physicist and priest John Polkinghorne, in his ''Questions of Truth'', discusses the subject of religion and science, a topic that other Christian apologists such as Ravi Zacharias, John Lennox, and William Lane Craig have engaged, with the latter two men opining that the Religious interpretations of the Big Bang theory, inflationary Big Bang model is evidence for the existence of God. Creationist apologetics is apologetics that aims to defend creationism.
