(involved in the material universe). In discussing God's relationship to His creation, Eastern Orthodox theology distinguishes between God's eternal essence, which is totally transcendent, and His ''uncreated energies'', which is how He reaches humanity. The God who is transcendent and the God who touches mankind are one and the same. That is, these energies are not something that proceed from God or that God produces, but rather they are God himself: distinct, yet inseparable from God's inner being. This view is often called Palamism. In understanding the Trinity as "one God in three persons", "three persons" is not to be emphasised more than "one God", and vice versa. While the three persons are distinct, they are united in one divine essence, and Their oneness is expressed in community and action so completely that They cannot be considered separately. For example, Their salvation of mankind is an activity engaged in common: "Christ became man by the good will of the Father and by the cooperation of the Holy Spirit. Christ sends the Holy Spirit who proceeds from the Father, and the Holy Spirit forms Christ in our hearts, and thus God the Father is glorified." Their "communion of essence" is "indivisible". Trinitarian terminology—essence, hypostasis, etc.—are used "philosophically", "to answer the ideas of the heretics", and "to place the terms where they separate error and truth".


Sin, salvation, and the incarnation

When Eastern Orthodox Christians refer to "fallen nature", they do not mean that human nature has become evil in itself. Human nature is still formed in the image of God; humans are still God's creation, and God has never created anything evil, but fallen nature remains open to evil intents and actions. It is sometimes said among the Eastern Orthodox that humans are "inclined to sin"; that is, people find some sinful things attractive. It is the nature of temptation to make sinful things seem the more attractive, and it is the fallen nature of humans that seeks or succumbs to the attraction. Eastern Orthodox Christians reject the Augustinian position that the descendants of Adam and Eve are actually guilty of the
original sin Original sin () in Christian theology refers to the condition of sinfulness that all humans share, which is inherited from Adam and Eve due to the Fall of man, Fall, involving the loss of original righteousness and the distortion of the Image ...

Christian life

Monastery of Rousanou in Greece. Church teaching is that Eastern Orthodox Christians, through baptism, enter a new life of salvation through repentance whose purpose is to share in the life of God through the work of the Holy Spirit. The Eastern Orthodox Christian life is a spiritual pilgrimage in which each person, through the imitation of Christ and ''

'', cultivates the practice of unceasing prayer. Each life occurs within the life of the church as a member of the
body of Christ In Christian theology, the term Body of Christ () has two main but separate meanings: it may refer to Jesus Christ's words over the bread at the celebration of the Jewish feast of Passover that "This is my body" in (see Last Supper), or it ...
. It is then through the fire of God's love in the action of the Holy Spirit that each member becomes more holy, more wholly unified with Christ, starting in this life and continuing in the next. The church teaches that everyone, being born in God's image, is called to theosis, fulfillment of the image in likeness to God. God the creator, having divinity by nature, offers each person participation in divinity by cooperatively accepting His gift of grace. This is not to be mistaken as participating in the essence of God but rather participating in His energies. This would mean that we do not become "divine", we still remain human but become "gods" by grace, or in other words "icons of the living God" as many call it. The Eastern Orthodox Church, in understanding itself to be the
Body of Christ In Christian theology, the term Body of Christ () has two main but separate meanings: it may refer to Jesus Christ's words over the bread at the celebration of the Jewish feast of Passover that "This is my body" in (see Last Supper), or it ...
, and similarly in understanding the Christian life to lead to the unification in Christ of all members of his body, views the church as embracing all Christ's members, those now living on earth, and also all those through the ages who have passed on to the heavenly life. The church includes the Christian saints from all times, and also judges, prophets and righteous Jews of the first covenant, Adam and Eve, even the angels and heavenly hosts. In Eastern Orthodox services, the earthly members together with the heavenly members worship God as one community in Christ, in a union that transcends time and space and joins heaven to earth. This unity of the Church is sometimes called the '' communion of the saints''.


Virgin Mary and other saints

Pre-eminent among the saints is the
Virgin Mary Mary was a first-century Jewish woman of Nazareth, the wife of Saint Joseph, Joseph and the mother of Jesus. She is an important figure of Christianity, venerated under titles of Mary, mother of Jesus, various titles such as Perpetual virginity ...

(symbolising the Mother of God's carrying of God without being consumed). The Eastern Orthodox believe that Christ, from the moment of his conception, was both fully God and fully human. Mary is thus called the ''Theotokos'' or ''Bogorodica'' as an affirmation of the divinity of the one to whom she gave birth. It is also believed that her virginity was not compromised in conceiving God-incarnate, that she was not harmed and that she remained forever a virgin. Scriptural references to "brothers" of Christ are interpreted as kin. Due to her unique place in salvation history according to Eastern Orthodox teaching, Mary is honoured above all other saints in this religion and especially venerated for the great work that God accomplished through her. The Eastern Orthodox Church regards the bodies of all saints as holy because of their participation in prescribed rituals called holy mysteries. Physical items connected with saints are also regarded as holy, through their participation in the earthly works of those saints. According to Eastern Orthodox church teaching and tradition, God himself bears witness to this holiness of saints'

Eschatology

Eastern Orthodox Christians believe that when a person dies the soul is temporarily separated from the body. Though it may linger for a short period on Earth, it is ultimately escorted either to paradise ( Abraham's bosom) or the darkness of

The soul's experience of either of these states is only a "foretaste"—being experienced only by the soul—until the Final Judgment, when the soul and body will be reunited.Rose, Father Seraphim, ''The Soul After Death'', St. Herman Press, Platina, CA, c. 1980 The Eastern Orthodox believe that the state of the soul in Hades can be affected by the love and prayers of the righteous up until the Last Judgment.

to its divinely inspired human authors. Holy scripture forms the primary and authoritative written witness of holy tradition and is essential as the basis for all Orthodox teaching and belief. Once established as holy scripture, there has never been any question that the Eastern Orthodox Church holds the full list of books to be venerable and beneficial for reading and study, even though it informally holds some books in higher esteem than others, the four gospels highest of all. Of the subgroups significant enough to be named, the "

" (ἀναγιγνωσκόμενα, "things that are read") comprises ten of the Old Testament books rejected in the Protestant canon, but deemed by the Eastern Orthodox worthy to be read in worship services, even though they carry a lesser esteem than the 39 books of the Hebrew canon. The lowest tier contains the remaining books not accepted by either Protestants or Catholics, among them, Psalm 151. Though it is a psalm, and is in the book of psalms, it is not classified as being within the Psalter (the first 150 psalms). Eastern Orthodoxy does not subscribe to the doctrine of '' sola scriptura''. Rather, Eastern Orthodoxy teaches that its church has defined what Scripture is, and therefore, its church also interprets the meanings of Scripture. Scriptures are understood by Eastern Orthodox interpretation to contain historical fact, poetry, idiom, metaphor, simile, moral fable, parable, prophecy and

, and each bears its own consideration in its interpretation. While divinely inspired, the text still consists of words in human languages, arranged in humanly recognisable forms. The Eastern Orthodox Church does not oppose honest critical and historical study of the Bible.


Holy tradition and patristic consensus

In Eastern Orthodoxy, " that faith which has been believed everywhere, always, and by all", the faith taught by Jesus to the apostles, given life by the

, and passed down to future generations without additions and without subtractions, is known as holy tradition. Holy tradition does not change in the Eastern Orthodox Church because it encompasses those things that do not change: the nature of the one God in Trinity, Father, Son, and Holy Spirit, the history of God's interactions with his peoples, the Law as given to the Israelites, all Christ's teaching as given to the disciples and Jews and recorded in scripture, including the parables, the prophecies, the miracles, and his own example to humanity in his extreme humility. It encompasses also the worship of the church, which grew out of the worship of the synagogue and temple and was extended by Christ at the last supper, and the relationship between God and his people which that worship expresses, which is also evidenced between Christ and his disciples. It includes the authority that Christ bestowed on his disciples when he made them apostles. Holy tradition is firm, even unyielding, but not rigid or legalistic; instead, it lives and breathes within the church. For example, the New Testament was entirely written by the early church (mostly the apostles). The whole Bible was accepted as scripture by means of holy tradition practised within the early church. The writing and acceptance took five centuries, by which time the holy scriptures themselves had become in their entirety a part of holy tradition. But holy tradition did not change, because "that faith which has been believed everywhere, always, and by all" remained consistent, without additions, and without subtractions. The historical development of the Divine Liturgy and other worship services and devotional practices of the church provide a similar example of extension and growth "without change". Besides these, holy tradition includes the doctrinal definitions and statements of faith of the seven ecumenical councils, including the
Nicene-Constantinopolitan Creed The Nicene Creed, also called the Creed of Constantinople, is the defining creed, statement of belief of Nicene Christianity and in those Christian denominations that adhere to it. The original Nicene Creed was first adopted at the First Counci ...

canon law Canon law (from , , a 'straight measuring rod, ruler') is a set of ordinances and regulations made by ecclesiastical jurisdiction, ecclesiastical authority (church leadership) for the government of a Christian organization or church and its membe ...
, and icons. Not all portions of holy tradition are held to be equally strong. Some—the holy scriptures foremost, certain aspects of worship, especially in the Divine Liturgy, the doctrines of the ecumenical councils, the Nicene-Constantinopolitan Creed—possess a verified authority that endures forever, irrevocably. However, with local councils and patristic writings, the church applies a selective judgement. Some councils and writers have occasionally fallen into error, and some contradict each other. In other cases, opinions differ, no consensus is forthcoming, and all are free to choose. With agreement among the Church Fathers, though, the authority of interpretation grows, and full patristic consensus is very strong. With canon law (which tends to be highly rigorous and very strict, especially with clergy) an unalterable validity also does not apply, since canons deal with living on earth, where conditions are always changing and each case is subject to almost infinite variation from the next. By tradition, the Eastern Orthodox Church, when faced with issues that are larger than a single bishop can resolve, holds a local council. The bishops convene (as St. Paul called the Corinthians to do) to seek the ''mind of the church''. A council's declarations or edicts then reflect its consensus (if one can be found). An ecumenical council is only called for issues of such importance, difficulty or pervasiveness that smaller councils are insufficient to address them. Ecumenical councils' declarations and canons carry binding weight by virtue of their representation across the whole church, by which the mind of the church can be readily seen. However, not all issues are so difficult as to require an ecumenical council to resolve. Some doctrines or decisions, not defined in a formal statement or proclaimed officially, nevertheless are held by the church unshakably and unanimously without internal disturbance, and these, also reflecting the mind of the church, are just as firmly irrevocable as a formal declaration of an ecumenical council. Lack of formality does not imply lack of authority within holy tradition.


Territorial expansion and doctrinal integrity

As the church increased in size through the centuries, the logistic dynamics of operating such large entities shifted: patriarchs, metropolitans, archimandrites, abbots and abbesses, all rose up to cover certain points of administration.

Lesser cycles also run in tandem with the annual ones. A weekly cycle of days prescribes a specific focus for each day in addition to others that may be observed:

; prayer services in the morning and evening, respectively. The celebration of the feasts are distinguished according to their various degrees of solemnity. The great feasts are celebrated with an All Night Vigil. Lesser feasts will have a vigil according to the feast's custom. Church service books are used in divine services, like the Gospel, the Epistle, and the Psalter. These books, often called ''divine service books'' were composed in accordance with the scriptures and traditions of the Church Fathers and teachers of the Orthodox Church. During fasting, in the middle of the week Holy Communion is given at all church services, without removing the characteristics of Orthodox Lent.


Chanting

Chanting is not considered "music" by Orthodox Christians, but rather sacred melody and prayer, in Orthodox Theology. An Orthodox Divine Service is chanted in its entirety by the clergy, the choir, and the congregation from the start of the service to the end. Early Christian forms of chanting began with ancient Judaic traditions of chanting the Psalms, which priests have now declared with the hymns in the Book of Psalms. As the Church grew, so did persecution, and many new forms of hymns began to appear. Liturgies contain the reading and chanting of prayers, headed by a bishop or priest. Forms of chanting services vary across liturgies (for example, the Liturgy of St. Basil the Great has chanting of longer duration and the priest privately reads his prayers at the altar). For the composition of religious chant, the Octoechos, an eight- tone (mode) system, analogous to the

. Byzantine chants are associated with the Eastern Roman Empire's period (AD 330 to 1453) and developed from Jewish and Syrian traditions in the early-Christian Church. This continued to evolve throughout the 16th century. However, many mistake it for Greek Christianity in the east, but is unrelated to the ancient Greek period. Northern Slavs, however, have used simpler tonal systems evolved through the sundry local types of Znamenny chant; today Western music, often with

. Henry Chadwick wrote, "In this instinct there was a measure of truth. The representations of Christ as the Almighty Lord on his judgment throne owed something to pictures of Zeus. Portraits of the Mother of God were not wholly independent of a pagan past of venerated mother-goddesses. In the popular mind the saints had come to fill a role that had been played by heroes and deities." Icons can be found adorning the walls of churches and often cover the inside structure completely. Most Eastern Orthodox homes have an area set aside for family prayer, usually an eastern facing wall, where are hung many icons. Icons have been part of Orthodox Christianity since the beginning of the church.

Holy Communion (Eucharist)

Communion is given only to baptised and chrismated Eastern Orthodox Christians who have prepared by fasting, prayer and confession. The priest administers the gifts, believed to be the Body and Blood of Christ, with a spoon, called a "cochlear", directly into the recipient's mouth from the chalice. From baptism young infants and children are carried to the chalice to receive holy communion.


Repentance (Confession)

There are many different practices regarding how often Eastern Orthodox Christians should go to confession. Some Patriarchates advise confession before each reception of Holy Communion, others advise confessing during each of the four fasting periods (
Great Lent Great Lent, or the Great Fast (Greek language, Greek: Μεγάλη Τεσσαρακοστή, ''Megali Tessarakosti'' or Μεγάλη Νηστεία, ''Megali Nisteia'', meaning "Great 40 Days", and "Great Fast", respectively), is the most impor ...
, Nativity Fast, Apostles' Fast and Dormition Fast), and there are many additional variants.


Marriage

From the Orthodox perspective, marriage is one of the holy mysteries or sacraments. As well as in many other Christian traditions, for example in Catholicism, it serves to unite a woman and a man in eternal union and love before God, with the purpose of following Christ and his Gospel and raising up a faithful, holy family through their holy union. The church understands marriage to be the union of one man and one woman, and certain Orthodox leaders have spoken out strongly in opposition to the civil institution of same-sex marriage. Jesus said that "when they rise from the dead, they neither marry nor are given in marriage, but are like angels in heaven" (Mk 12:25). For the Orthodox Christian this passage should not be understood to imply that Christian marriage will not remain a reality in the Kingdom, but points to the fact that relations will not be "fleshy", but "spiritual". Love between wife and husband, as an icon of relationship between Christ and Church, is eternal. The church does recognise that there are rare occasions when it is better that couples do separate, but there is no official recognition of civil divorces. For the Eastern Orthodox, to say that marriage is indissoluble means that it should not be broken, the violation of such a union, perceived as holy, being an offense resulting from either adultery or the prolonged absence of one of the partners. Thus, permitting remarriage is an act of compassion of the church towards sinful man.


Holy orders

Widowed priests and deacons may not remarry and it is common for such members of the clergy to retire to a monastery (see clerical celibacy). This is also true of widowed wives of clergy, who do not remarry and become nuns when their children are grown. Only men are allowed to receive holy orders, although deaconesses historically had both liturgical and pastoral functions within the church. In 2016, the Patriarchate of Alexandria decided to reintroduce the order of deaconess. In February 2017, Patriarch Theodore II of Alexandria, Patriarch Theodore II consecrated five women to be deacons within the Greek Orthodox Church of Alexandria, Patriarchate of Alexandria.

Local customs

Locality is also expressed in regional terms of churchly jurisdiction, which is often also drawn along national lines. Many Orthodox churches adopt a national title (e.g. Orthodox Autocephalous Church of Albania, Albanian Orthodox, Bulgarian Orthodox Church, Bulgarian Orthodox, Georgian Orthodox Church, Georgian Orthodox, Greek Orthodox Church, Greek Orthodox, Romanian Orthodox Church, Romanian Orthodox, Russian Orthodox Church, Russian Orthodox, Serbian Orthodox Church, Serbian Orthodox, Orthodox Church of Ukraine, Ukrainian Orthodox, etc.) and this title can identify which language is used in services, which bishops preside, and which of the ''typica'' is followed by specific wikt:congregation, congregations. In the Middle East, Orthodox Christians are usually referred to as ''Rum (endonym), Rum'' ("Roman") Orthodox, because of their historical connection with the Byzantine Empire, Eastern Roman (Byzantine) Empire.
