The Catholic Church (), also known as the Roman Catholic Church, is the
largest Christian church, with 1.27 to 1.41 billion
baptized Catholics
worldwide as of 2025.
It is among the world's oldest and largest international institutions and has played a prominent role in the history and development of
Western civilization.

''sui iuris'' (autonomous) churches, including the
Latin Church and 23
Eastern Catholic Churches, which comprise almost 3,500

s and
eparchies around the world, each overseen by one or more
bishops. The
pope, who is the bishop of Rome, is the
chief pastor of the church.
The core beliefs of Catholicism are found in the
Nicene Creed. The Catholic Church teaches that it is the
one, holy, catholic and apostolic church founded by
Jesus Christ in his
Great Commission,
that its
bishops are the
successors of Christ's
apostles, and that the pope is the
successor of
Saint Peter, upon whom
primacy was conferred by Jesus Christ. It maintains that it practises the original Christian faith taught by the apostles, preserving the faith
infallibly through
scripture and
sacred tradition as authentically interpreted through the
magisterium or teaching office of the church.
The
Roman Rite and
others of the Latin Church, the
Eastern Catholic liturgies, and communities and societies such as
mendicant orders,
enclosed monastic orders,
third orders and voluntary charitable lay
associations reflect a
variety of
theological and
spiritual emphases in the church.

In a review of an article from the Encyclopedia of Religion, Gunton writes: " e article n Catholicism in the encyclopediarightly suggests caution, suggesting at the outset that Roman Catholicism is marked by several different doctrinal, theological and liturgical emphases."]
Of its
seven sacraments, the
Eucharist is the principal one, celebrated
liturgically in the
Mass. The church teaches that through

Saint Ignatius of Antioch to the
Smyrnaeans, which read: "Wheresoever the bishop shall appear, there let the people be, even as where Jesus may be, there is the universal

In the ''Catechetical Lectures'' () of

At Pentecost, the apostles are believed to have received the Holy Spirit, preparing them for their mission in leading the church. The Catholic Church teaches that the

successors to the Apostles.

, Christ designates Peter as the "rock" upon which Christ's church will be built. The Catholic Church considers the bishop of Rome, the pope, to be the successor to
Saint Peter. Some scholars state Peter was the first bishop of Rome.
Others say that the institution of the papacy is not dependent on the idea that Peter was bishop of Rome or even on his ever having been in Rome.
Many scholars hold that a church structure of plural presbyters/bishops persisted in Rome until the mid-2nd century, when the structure of a single bishop and plural presbyters was adopted,
and that later writers retrospectively applied the term "bishop of Rome" to the most prominent members of the clergy in the earlier period and also to Peter himself.
On this basis
Bart D. Ehrman,as well as protestant scholars
Oscar Cullmann and
Henry Chadwick, question whether there was a formal link between Peter and the modern papacy.
Raymond E. Brown also says that it is anachronistic to speak of Peter in terms of local bishop of Rome, but that Christians of that period would have looked on Peter as having "roles that would contribute in an essential way to the development of the role of the papacy in the subsequent church". These roles, Brown says, "contributed enormously to seeing the bishop of Rome, the bishop of the city where Peter died and where Paul witnessed the truth of Christ, as the successor of Peter in care for the church universal".

facilitated the spread of new ideas. The empire's network of roads and waterways facilitated travel, and the ''

Unlike most religions in the Roman Empire, however, Christianity required its adherents to renounce all other gods, a practice adopted from Judaism (see
Idolatry). The Christians' refusal to join
pagan celebrations meant they were unable to participate in much of public life, which caused non-Christians—including government authorities—to fear that the Christians were angering the gods and thereby threatening the peace and prosperity of the Empire. The
resulting persecutions were a defining feature of Christian self-understanding until Christianity was legalized in the 4th century.

["Rome (early Christian)". Cross, F.L., ed., ''The Oxford Dictionary of the Christian Church''. New York: Oxford University Press. 2005] Emperor
Justinian, who in the areas under his control definitively established a form of
caesaropapism, in which "he had the right and duty of regulating by his laws the minutest details of worship and discipline, and also of dictating the theological opinions to be held in the Church", re-established imperial power over Rome and other parts of the West, initiating the period termed the
Byzantine Papacy (537–752), during which the bishops of Rome, or popes, required approval from the emperor in Constantinople or from his representative in Ravenna for consecration. Most were selected by the emperor from his Greek-speaking subjects, resulting in a "melting pot" of Western and Eastern Christian traditions in art as well as liturgy.
Most of the Germanic tribes who in the following centuries invaded the Roman Empire adopted Christianity in its
Arian form, which the
Council of Nicaea declared
heretical. The resulting religious discord between Germanic rulers and Catholic subjects was avoided when, in 497,
Clovis I, the
Frankish ruler, converted to orthodox Catholicism, allying himself with the papacy and the monasteries. The Visigoths in Spain followed his lead in 589, and the Lombards in Italy in the course of the 7th century.
Western Christianity, particularly through its
monasteries, was a major factor in preserving
classical civilization, with its art (see

Through his

Benedict of Nursia (–543), one of the founders of

The university is generally regarded as an institution that has its origin in the
Medieval Christian setting.

and
Tours halted the Islamic advance in the West and the failed
siege of Constantinople halted it in the East. Two or three decades later, in 751, the Byzantine Empire lost to the Lombards the city of Ravenna from
which it governed the small fragments of Italy, including Rome, that acknowledged its sovereignty. The fall of Ravenna meant that confirmation by a no longer existent exarch was not asked for during the election in 752 of
Pope Stephen II, and that the papacy was forced to look elsewhere for a civil power to protect it.
In 754, at the urgent request of Pope Stephen, the Frankish king
Pepin the Short conquered the Lombards. He then
gifted the lands of the former exarchate to the pope, initiating the
Papal States. In the 860s, Rome and the Byzantine East were in conflict during the
Photian schism, when
Photius criticized the Latin west for adding of the ''
filioque'' clause, after being excommunicated by
Nicholas I. Though the schism was reconciled, unresolved issues would lead to further division.

In the 11th century, the efforts of
Hildebrand of Sovana led to the creation of the
College of Cardinals to elect new popes, starting with
Pope Alexander II in the
papal election of 1061. When Alexander II died, Hildebrand was elected to succeed him, as
Pope Gregory VII. The basic election system of the College of Cardinals which Gregory VII helped establish has continued to function into the 21st century. Pope Gregory VII further initiated the
Gregorian Reforms regarding the independence of the clergy from secular authority. This led to the
Investiture Controversy between the church and the
Holy Roman Emperors, over which had the authority to appoint bishops and popes.
[Vidmar, ''The Catholic Church Through the Ages'' (2005), pp. 107–11][Duffy, ''Saints and Sinners'' (1997), p. 78, quote: "By contrast, Paschal's successor Eugenius II (824–27), elected with imperial influence, gave away most of these papal gains. He acknowledged the Emperor's sovereignty in the papal state, and he accepted a constitution imposed by Lothair which established imperial supervision of the administration of Rome, imposed an oath to the Emperor on all citizens, and required the pope–elect to swear fealty before he could be consecrated. Under Sergius II (844–847) it was even agreed that the pope could not be consecrated without an imperial mandate and that the ceremony must be in the presence of his representative, a revival of some of the more galling restrictions of Byzantine rule."]
In 1095, Byzantine emperor
Alexius I appealed to
Pope Urban II for help against renewed Muslim invasions in the
Byzantine–Seljuk wars,
[Riley-Smith, p. 8] which caused Urban to launch the
First Crusade aimed at aiding the Byzantine Empire and returning the
Holy Land to Christian control. In the
11th century, strained relations between the primarily Greek church and the Latin Church separated them in the East–West Schism, partially due to conflicts over
papal authority. The
Fourth Crusade and the sacking of Constantinople by renegade crusaders proved the final breach.
In the twelfth century,
Inquisitions—Church investigations of individuals under suspicions of heresy—began in the Catholic
Kingdom of France

A growing sense of church-state conflicts marked the 14th century. In 1309, to escape instability in Rome,
Clement V became the first of seven popes to reside in the fortified city of
Avignon in southern France
[Duffy, ''Saints and Sinners'' (1997), p. 122] during a period known as the
Avignon Papacy. The Avignon Papacy ended in 1376 when the pope returned to Rome.
[Morris, p. 232] In 1378, a 38-year-long
Western Schism began, with claimants to the papacy located in Rome, Avignon and after 1409, Pisa.
The matter was largely resolved in 1414–1418 at the
Council of Constance, with the claimants in Rome and Pisa agreeing to resign and the third claimant excommunicated by the cardinals, who held a new election naming
Martin V pope.
[McManners, p. 240]
In 1438, the
Council of Florence convened, which featured a strong dialogue focussed on understanding the theological differences between the East and West, with the hope of reuniting the Catholic and Orthodox churches. Several eastern churches reunited, forming the majority of the
Eastern Catholic Churches.
Age of Discovery and Counter-Reformation
The
Age of Discovery beginning in the 15th century saw the expansion of Western Europe's political and cultural influence worldwide. Because of the rise in power overseas of strongly Catholic nations of Spain and Portugal (as well as France), Catholicism was spread to the Americas, Asia and Oceania by explorers, conquistadors, and missionaries, as well as by the conversion of people who lived in these societies to the Catholic faith.

The
Council of Trent (1545–1563) became the driving force behind the
Counter-Reformation in response to the Protestant movement. Doctrinally, it reaffirmed many central Catholic teachings such as
transubstantiation, the keeping of the
sacraments, and the requirement of

anchored in love and hope to justify one's salvation, as well as faith as a necessary condition to attain such salvation. In subsequent centuries, Catholicism spread widely across the world, in part through missionaries and
imperialism, although its hold on European populations declined due to the growth of
religious scepticism during and after the Enlightenment.
Enlightenment and modern period
From the 17th century onward, the Enlightenment questioned the power and influence of the Catholic Church over Western society.
[Pollard, pp. 7–8] In the 18th century, writers such as
Voltaire and the ''
Encyclopédistes'' wrote biting critiques of both religion and the Catholic Church. One target of their criticism was the 1685
revocation of the Edict of Nantes by King
Louis XIV of France, which ended a century-long policy of religious toleration of Protestant Huguenots. As the papacy resisted pushes for
Gallicanism, the
French Revolution of 1789 shifted power to the state, caused the destruction of churches, the establishment of a
Cult of Reason, and the martyrdom of
nuns during the ''
Reign of Terror''. In 1798,
Napoleon Bonaparte's General
Louis-Alexandre Berthier invaded the
Italian Peninsula, imprisoning
Pope Pius VI, who died in captivity. Napoleon later re-established the Catholic Church in France through the
Concordat of 1801.

In 1854,
Pope Pius IX, with the support of the overwhelming majority of Catholic bishops, whom he had consulted from 1851 to 1853, proclaimed the
Immaculate Conception as a
dogma in the Catholic Church. In 1870, the
First Vatican Council affirmed the doctrine of
papal infallibility

conciliarism. Controversy over this and other issues resulted in a breakaway movement called the
Old Catholic Church.
[Fahlbusch, ''The Encyclopedia of Christianity'' (2001), p. 729]
The
Italian unification of the 1860s incorporated the Papal States, including Rome itself from 1870, into the
Kingdom of Italy, thus ending the papacy's
temporal power. In response, Pope Pius IX excommunicated
King Victor Emmanuel II, refused payment for the land, and rejected the Italian
Law of Guarantees, which granted him special privileges. To avoid placing himself in visible subjection to the Italian authorities, he remained a "
prisoner in the Vatican". This stand-off, which was spoken of as the ''
Roman Question'', was resolved by the 1929
Lateran Treaties, whereby the Holy See acknowledged Italian sovereignty over the former Papal States in return for payment and Italy's recognition of papal sovereignty over Vatican City as a new sovereign and independent state.
Catholic missionaries generally supported, and sought to facilitate, the European imperial powers'
conquest of Africa during the late nineteenth century. According to the historian of religion
Adrian Hastings, Catholic missionaries were generally unwilling to defend African rights or encourage Africans to see themselves as equals to Europeans, in contrast to Protestant missionaries, who were more willing to oppose colonial injustices.
20th century

During the 20th century, the church's global reach continued to grow, despite the rise of
anti-Catholic authoritarian regimes and the collapse of European Empires, accompanied by a general decline in religious observance in the West. Under Popes
Benedict XV, and
Pius XII, the
Holy See sought to maintain public neutrality through the World Wars, acting as peace broker and delivering aid to the victims of the conflicts. In the 1960s,
Pope John XXIII convened the
Second Vatican Council, which ushered in radical change to church ritual and practice, and in the later 20th century, the long reign of
Pope John Paul II
Pope John Paul II (born Karol Józef Wojtyła; 18 May 19202 April 2005) was head of the Catholic Church and sovereign of the Vatican City State from 16 October 1978 until Death and funeral of Pope John Paul II, his death in 2005.

From the late 20th century, the Catholic Church has been
criticized for its doctrines on

ordain women, and its handling of
sexual abuse cases.
Pope
Pius X (1903–1914) renewed the independence of papal office by abolishing the veto of Catholic powers in papal elections, and his successors Benedict XV (1914–1922) and
Pius XI (1922–1939) concluded the modern independence of the Vatican State within Italy. Benedict XV was elected at the outbreak of the
First World War
World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a World war, global conflict between two coalitions: the Allies of World War I, Allies (or Entente) and the Central Powers. Fighting to ...

Pope Pius XI modernized the papacy, appointing 40 indigenous bishops and concluding fifteen concordats, including the
Lateran Treaty with Italy which founded the
Vatican City State.
His successor
Pope Pius XII led the Catholic Church through the
Second World War and early
Cold War. Like his predecessors, Pius XII sought to publicly maintain Vatican neutrality in the War and established aid networks to help victims, but he secretly
assisted the anti-Hitler resistance and shared intelligence with the Allies.
His first
encyclical ''
Summi Pontificatus'' (1939) expressed dismay at the
1939 Invasion of Poland and reiterated Catholic teaching against racism.
[Cook, p. 983] He expressed concern against race killings
on Vatican Radio, and intervened diplomatically to attempt to block Nazi deportations of Jews in various countries from 1942 to 1944. However, the Pope's insistence on public neutrality and diplomatic language has become a source of much criticism and debate. Nevertheless, in every country under German occupation, priests played a major part in rescuing Jews. Israeli historian
Pinchas Lapide estimated that
Catholic rescue of Jews amounted to somewhere between 700,000 and 860,000 people.
The
Nazi persecution of the Catholic Church was at its most intense
in Poland, and
Catholic resistance to Nazism took various forms. Some 2,579 Catholic clergy were sent to the
Priest Barracks of
Dachau Concentration Camp, including 400 Germans. Thousands of priests, nuns and brothers were imprisoned, taken to a concentration camp, tortured and murdered, including Saints
Maximilian Kolbe and
Edith Stein. Catholics fought on both sides in the conflict. Catholic clergy played a leading role in the government of the fascist
Slovak State, which collaborated with the Nazis, copied their anti-Semitic policies, and helped them carry out the Holocaust in Slovakia.
Jozef Tiso, the President of the Slovak State and a Catholic priest, supported his government's deportation of Slovakian Jews to extermination camps. The Vatican protested against these Jewish deportations in Slovakia and in other Nazi puppet regimes including
Vichy France, Croatia,

Around 1943,
Adolf Hitler planned the kidnapping of the Pope and his internment in Germany. He gave SS General Wolff a corresponding order to prepare for the action. While Pope Pius XII has been credited with helping to
save hundreds of thousands of Jews during the
Holocaust,
[Deák, p. 182] the church has also been accused of having encouraged centuries of
antisemitism by its teachings and not doing enough to stop Nazi atrocities. Many Nazi criminals escaped overseas after the Second World War, also because they had powerful supporters from the Vatican. The judgment of Pius XII is made more difficult by the sources, because the church archives for his tenure as nuncio, cardinal secretary of state and pope are in part closed or not yet processed.
The Second Vatican Council (1962–65) introduced the most significant changes to Catholic practices since the Council of Trent, four centuries before. Initiated by Pope John XXIII, this ecumenical council modernized the practices of the Catholic Church, allowing the Mass to be said in the
vernacular (local language) and encouraging "fully conscious, and active participation in liturgical celebrations". It intended to engage the church more closely with the present world (''
aggiornamento''), which was described by its advocates as an "opening of the windows".
[Duffy, pp. 270–76] In addition to changes in the liturgy, it led to changes to the church's approach to
ecumenism, and a call to improved relations with non-Christian religions, especially Judaism, in its document ''
Nostra aetate''.
The council, however, generated significant controversy in implementing its reforms: proponents of the "
Spirit of Vatican II" such as Swiss theologian
Hans Küng said that Vatican II had "not gone far enough" to change church policies.
Traditionalist Catholics, such as
Archbishop Marcel Lefebvre, however, strongly criticized the council, arguing that its liturgical reforms led "to the destruction of the Holy Sacrifice of the Mass and the sacraments", among other issues. The teaching on the morality of
contraception also came under scrutiny; after a series of disagreements, ''
Humanae vitae'' upheld the church's prohibition of all forms of contraception.
[While ruling contraception to be prohibited, Pope Paul VI did, however, consider natural family planning methods to be morally permissible if used with just cause.]
In 1978, Pope
John Paul II, formerly
Archbishop of Kraków in the
Polish People's Republic, became the first non-Italian pope in 455 years. His 26 1/2-year
pontificate was one of the longest in history and was credited with hastening the fall of communism in Europe. John Paul II sought to evangelize an increasingly
secular world. He travelled more than any other pope, visiting 129 countries, and used television and radio as means of spreading the church's teachings. He also emphasized the
dignity of work and natural rights of labourers to have
fair wages and safe conditions in ''
Laborem exercens''. He emphasized several church teachings, including moral exhortations against abortion,
euthanasia, and against widespread use of the death penalty, in ''
Evangelium Vitae''.
21st century
Pope Benedict XVI, elected in 2005, was known for upholding traditional
Christian values against
secularization, and for increasing use of the
Tridentine Mass as found in the
Roman Missal of 1962, which he titled the "Extraordinary Form". Citing the frailties of advanced age, Benedict
resigned in 2013, becoming the first pope to do so in nearly 600 years.
Pope Francis became in 2013 the first pope from the Americas, the first from the
Southern Hemisphere, and the first Pope from outside Europe since the eighth-century
Gregory III. Francis made efforts to further close Catholicism's estrangement with the Eastern churches.

Organization

The Catholic Church follows an
episcopal polity, led by bishops who have received the sacrament of
Holy Orders who are given formal
jurisdictions of governance within the church.
[ "It is usual to distinguish a twofold hierarchy in the Church, that of order and that of jurisdiction, corresponding to the twofold means of sanctification, grace, which comes to us principally through the sacraments, and good works, which are the fruit of grace."] There are three levels of clergy: the episcopate, composed of bishops who hold jurisdiction over a geographic area called a
diocese
In Ecclesiastical polity, church governance, a diocese or bishopric is the ecclesiastical district under the jurisdiction of a bishop.
History
In the later organization of the Roman Empire, the increasingly subdivided Roman province, prov ...
or
eparchy; the presbyterate, composed of priests ordained by bishops and who work in local dioceses or religious orders; and the diaconate, composed of deacons who assist bishops and priests in a variety of ministerial roles. Ultimately leading the entire Catholic Church is the
bishop of Rome, known as the pope (), whose jurisdiction is called the
Holy See ( in Latin).
In parallel to the diocesan structure are a variety of
religious institutes that function autonomously, often subject only to the authority of the pope, though sometimes subject to the local bishop. Most religious institutes only have male or female members but some have both. Additionally,
lay members aid many liturgical functions during worship services. The Catholic Church has been described as the oldest
multinational organization in the world.
Holy See, papacy, Roman Curia, and College of Cardinals
The
hierarchy of the Catholic Church is headed by the pope, currently
Pope Leo XIV, who was elected on the 8th of May 2025 by
a papal conclave. The office of the pope is known as the ''papacy''. The Catholic Church holds that Christ instituted the papacy upon giving the
keys of Heaven to
Saint Peter. His ecclesiastical jurisdiction is called the Holy See, or the
Apostolic See (meaning the see of the apostle Peter). Directly serving the pope is the Roman Curia, the central governing body that administers the day-to-day business of the Catholic Church.
The pope is also
sovereign of Vatican City, a small
city-state entirely enclaved within the city of Rome, which is an entity distinct from the Holy See. It is as head of the Holy See, not as head of Vatican City State, that the pope receives ambassadors of states and sends them his own diplomatic representatives. The Holy See also confers
orders, decorations and medals, such as the
orders of chivalry originating from the
Middle Ages.
While the famous
Saint Peter's Basilica is located in Vatican City, above the traditional site of
Saint Peter's tomb, the papal cathedral for the Diocese of Rome is the
Archbasilica of Saint John Lateran, located within the city of Rome, though enjoying
extraterritorial privileges accredited to the Holy See.
The position of
cardinal is a rank of honour bestowed by popes on certain clerics, such as leaders within the Roman Curia, bishops serving in major cities and distinguished theologians. For advice and assistance in governing, the pope may turn to the
College of Cardinals.
[McDonough (1995), p. 227]
Following the death or resignation of a pope, members of the College of Cardinals who are under age 80 act as an
electoral college, meeting in a
papal conclave to elect a successor.
[Duffy (1997), p. 416] Although the conclave may elect any male Catholic as pope, since 1389 only cardinals have been elected.

Eastern Catholic canon law govern the 23 Eastern Catholic
particular churches ''

The actual subject material of the canons is not just doctrinal or moral in nature, but all-encompassing of the human condition. It has all the ordinary elements of a mature legal system:

In its own field it gives force to civil law only by specific enactment in matters such as the guardianship of minors. Similarly, civil law may give force in its field to canon law, but only by specific enactment, as with regard to canonical marriages.
Currently, the
1983 Code of Canon Law is in effect for the Latin Church. The distinct 1990 ''
Code of Canons of the Eastern Churches'' (''CCEO'', after the Latin initials) applies to the autonomous Eastern Catholic Churches.
Latin and Eastern churches
In the first thousand years of Catholic history, different varieties of Christianity developed in the Western and
Eastern Christian areas of Europe, Asia and Africa. Though most Eastern-tradition churches are no longer in communion with the Catholic Church after the
Great Schism of 1054 (as well as the earlier
Nestorian Schism and
Chalcedonian Schism), 23 autonomous
particular churches of eastern traditions participate in the Catholic communion, also known as "churches ''
sui iuris''" ("). The largest and most well known is the Latin Church, the only Western-tradition church, with more than 1 billion members worldwide. Relatively small in terms of adherents compared to the Latin Church, are the 23 self-governing Eastern Catholic Churches with a combined membership of 17.3 million .
[Colin Gunton. "Christianity among the Religions in the Encyclopedia of Religion", ''Religious Studies'', Vol. 24, no. 1, p. 14. In a review of an article from the ''Encyclopedia of Religion'', Gunton writes "... he article n Catholicism in the encyclopediarightly suggests caution, suggesting at the outset that Roman Catholicism is marked by ''several different doctrinal and theological emphases''."]
The Latin Church is governed by the pope and diocesan bishops directly appointed by him. The pope exercises a direct
patriarchal role over the Latin Church, which is considered to form the original and still major part of
Western Christianity, a heritage of certain beliefs and customs originating in Europe and northwestern Africa, some of which are inherited by many
Christian denominations that trace their origins to the Protestant Reformation.

The Eastern Catholic Churches follow the traditions and spirituality of
Eastern Christianity and are churches that have always remained in full communion with the Catholic Church or who have chosen to re-enter full communion in the centuries following the
East–West Schism or earlier divisions. These churches are communities of Catholic Christians whose forms of worship reflect distinct historical and cultural influences rather than differences in doctrine.
The pope's recognition of Eastern Catholic Churches has caused controversy in
ecumenical relations with the Eastern Orthodox and other eastern churches. Historically, pressure to conform to the norms of the Western Christianity practised by the majority Latin Church led to a degree of encroachment (
Liturgical Latinisation) on some of the Eastern Catholic traditions. The
Second Vatican Council document, ''
Orientalium Ecclesiarum'', built on previous reforms to reaffirm the right of Eastern Catholics to maintain their distinct liturgical practices.
A church ''sui iuris'' is defined in the ''
Code of Canons for the Eastern Churches'' as a "group of Christian faithful united by a hierarchy" that is recognized by the pope in his capacity as the
supreme authority on matters of doctrine within the church. The Eastern Catholic Churches are in
full communion with the pope, but have governance structures and liturgical traditions separate from that of the Latin Church.
While the Latin Church's canons do not explicitly use the term, it is tacitly recognized as equivalent.
Some Eastern Catholic churches are governed by a patriarch who is elected by the
synod of the bishops of that church,

These are not ordained, nor generally considered ministers unless also engaged in one of the lay minister categories above.
Doctrine
Catholic doctrine has developed over the centuries, reflecting direct teachings of early Christians, formal definitions of
heretical and
orthodox beliefs by
ecumenical councils and in
papal bulls, and theological debate by scholars. The church believes that it is continually guided by the Holy Spirit as it discerns new theological issues and is protected
infallibly from falling into doctrinal error when a firm decision on an issue is reached.
It teaches that revelation has one common source,
God, and two distinct modes of transmission: Sacred Scripture and
Sacred Tradition,
and that these are authentically interpreted by the
Magisterium. Sacred Scripture consists of the 73 books of the
Catholic Bible, consisting of 46
Old Testament and 27
New Testament
The New Testament (NT) is the second division of the Christian biblical canon. It discusses the teachings and person of Jesus in Christianity, Jesus, as well as events relating to Christianity in the 1st century, first-century Christianit ...
writings. Sacred Tradition consists of those teachings believed by the church to have been handed down since the time of the Apostles.
[Schreck, pp. 15–19] Sacred Scripture and Sacred Tradition are collectively known as the "deposit of faith" ( in Latin). These are in turn interpreted by the Magisterium (from , Latin for "teacher"), the church's teaching authority, which is exercised by the pope and the
College of Bishops in union with the pope, the Bishop of Rome.
[Schreck, p. 30] Catholic doctrine is authoritatively summarized in the ''
Catechism of the Catholic Church'', published by the Holy See.
[Marthaler, preface]
Nature of God

The Catholic Church holds that there is one
eternal God, who exists as a ''
perichoresis'' ("mutual indwelling") of three ''
hypostases'', or "persons":
God the Father;
God the Son; and
God the Holy Spirit (also called the Holy Ghost), which together are called the "Holy Trinity".
Catholics believe that Jesus Christ is the "Second Person" of the Trinity, God the Son. In an event known as the
Incarnation, through the power of the Holy Spirit, God became united with human nature through the conception of Christ in the womb of the
Blessed Virgin Mary. Christ, therefore, is understood as being both fully divine and fully human, including possessing a human
soul. It is taught that Christ's mission on earth included giving people his teachings and providing his example for them to follow as recorded in the four
Gospel

s.
[McGrath, pp. 4–6.] Jesus is believed to have remained sinless while on earth, and to have allowed himself to be unjustly executed by
crucifixion, as a sacrifice of himself to reconcile humanity to God; this reconciliation is known as the
Paschal Mystery. The Greek term "Christ" and the Hebrew "Messiah" both mean "anointed one", referring to the Christian belief that Jesus' death and resurrection are the fulfilment of the Old Testament's
messianic prophecies.
[Kreeft, pp. 71–72]
The Catholic Church teaches dogmatically that "the Holy Spirit proceeds eternally from the Father and the Son, not as from two principles but as from one single principle". It holds that the Father, as the "principle without principle", is the first origin of the Spirit, but also that he, as Father of the only Son, is with the Son the single principle from which the Spirit proceeds. This belief is expressed in the clause which was added to the Latin version of the Nicene Creed of 381 but not included in the Greek versions of the creed used in Eastern Christianity.
Nature of the church
The Catholic Church teaches that it is the "
one true church",
"the universal sacrament of salvation for the human race",
and "the one true religion". According to the ''Catechism'', the Catholic Church is further described in the Nicene Creed as the "one, holy, catholic, and apostolic Church". These are collectively known as the
Four Marks of the Church. The church teaches that its founder is Jesus Christ.
[Kreeft, p. 98, quote "The fundamental reason for being a Catholic is the historical fact that the Catholic Church was founded by Christ, was God's invention, not man's;... As the Father gave authority to Christ (Jn 5:22; Mt 28:18–20), Christ passed it on to his apostles (Lk 10:16), and they passed it on to the successors they appointed as bishops." (see also Kreeft, p. 980)] The
New Testament
The New Testament (NT) is the second division of the Christian biblical canon. It discusses the teachings and person of Jesus in Christianity, Jesus, as well as events relating to Christianity in the 1st century, first-century Christianit ...
records several events considered integral to the establishment of the Catholic Church, including Jesus' activities and teaching and his appointment of the
apostles as witnesses to his ministry, suffering, and resurrection. The
Great Commission, after his resurrection, instructed the apostles to continue his work. The coming of the Holy Spirit upon the apostles, in an event known as
Pentecost, is seen as the beginning of the public ministry of the Catholic Church.
[Barry, p. 46.] The church teaches that all duly consecrated bishops have a lineal succession from the apostles of Christ, known as
apostolic succession.
[Barry, p. 46] In particular, the Bishop of Rome (the pope) is considered the successor to the apostle
Simon Peter, a position from which he derives his
supremacy over the church.
Catholic belief holds that the church "is the continuing presence of Jesus on earth"
[Schreck, p. 131] and that it alone possesses the full means of
salvation.
Through the
passion (suffering) of Christ leading to his
crucifixion as described in the Gospels, it is said Christ made himself an oblation to God the Father to
reconcile humanity to God;
the
Resurrection of Jesus makes him the firstborn from the dead, the first among many brethren. By reconciling with God and following Christ's words and deeds, an individual can enter the
Kingdom of God.
[Barry, p. 26] The church sees its liturgy and sacraments as perpetuating the graces achieved through Christ's sacrifice to strengthen a person's relationship with Christ and aid in overcoming sin.
Final judgement
The Catholic Church teaches that, immediately after death, the
soul of each person will receive a
particular judgement from God, based on their
sins and their relationship to Christ.
[Schreck, p. 397] This teaching also attests to another day when Christ will sit in universal judgement of all mankind. This
final judgement, according to the church's teaching, will bring an end to human history and mark the beginning of both a new and better heaven and earth ruled by God in righteousness.
Depending on the judgement rendered following death, it is believed that a soul may enter one of three states of the afterlife:
*
Heaven is a state of unending union with the divine nature of God, not ontologically, but by grace. It is an eternal life, in which the soul contemplates God in ceaseless
beatitude.
*
Purgatory is a temporary condition for the purification of souls who, although destined for Heaven, are not fully detached from sin and thus cannot enter Heaven immediately. In Purgatory, the soul suffers, and is purged and perfected. Souls in purgatory may be aided in reaching heaven by the prayers of the faithful on earth and by the
intercession of saints.
*
Final Damnation: Finally, those who persist in living in a state of mortal sin and do not repent before death subject themselves to hell, an everlasting separation from God. The church teaches that no one is condemned to hell without having freely decided to reject God. No one is
predestined to hell and no one can determine with absolute certainty who has been condemned to hell. Catholicism teaches that through God's mercy a person can repent at any point before death, be illuminated with the truth of the Catholic faith, and thus obtain salvation.
[Christian Bible, ] Some Catholic theologians have speculated that the souls of unbaptized infants and non-Christians without mortal sin but who die in
original sin are assigned to
limbo, although this is not an official
dogma of the church.
While the Catholic Church teaches that it alone possesses the full means of salvation,
it also acknowledges that the Holy Spirit can make use of
Christian communities separated from itself to "impel towards Catholic unity"
and "tend and lead toward the Catholic Church",
and thus bring people to salvation, because these separated communities contain some elements of proper doctrine, albeit admixed with
errors. It teaches that anyone who is saved is saved through the Catholic Church but that people can be saved outside of the ordinary means known as
baptism of desire, and by pre-baptismal martyrdom, known as
baptism of blood, as well as when conditions of
invincible ignorance are present, although invincible ignorance in itself is not a means of salvation. The
Vatican II document
Lumen Gentium further clarifies the possibility of salvation of those who "through no fault of their own, do not know the Gospel of Christ or his Church, but who nevertheless seek God with a sincere heart," being "moved by (divine) grace".
Saints and devotions
A saint (also historically known as a hallow) is a person who is recognized as having an exceptional degree of holiness or likeness or closeness to God, while canonization is the act by which a Christian church declares that a person who has died was a saint, upon which declaration the person is included in the "canon", or list, of recognized saints.
The first persons honoured as saints were the
martyrs. Pious legends of their deaths were considered affirmations of the truth of their faith in Christ. By the fourth century, however, "
confessors"—people who had confessed their faith not by dying but by suffering—began to be venerated publicly.
In the Catholic Church, both in Latin and Eastern Catholic churches, the act of canonization is reserved to the
Apostolic See and occurs at the conclusion of a long process requiring extensive proof that the candidate for canonization lived and died in such an exemplary and holy way that he is worthy to be recognized as a saint. The church's official recognition of sanctity implies that the person is now in
Heaven and that he may be publicly invoked and mentioned officially in the
liturgy of the church, including in the
Litany of the Saints.
Canonization allows universal veneration of the saint in the liturgy of the
Roman Rite; for permission to venerate merely locally, only
beatification
Beatification (from Latin , "blessed" and , "to make") is a recognition accorded by the Catholic Church of a deceased person's entrance into Heaven and capacity to intercede on behalf of individuals who pray in their name. ''Beati'' is the p ...
is needed.
Devotions are "external practices of piety" which are not part of the official liturgy of the Catholic Church but are part of the popular spiritual practices of Catholics. These include various practices regarding the veneration of the saints, especially
veneration of the Virgin Mary. Other devotional practices include the
Stations of the Cross, the
Sacred Heart of Jesus, the
Holy Face of Jesus,
the various
scapulars, novenas to various saints,
pilgrimages and devotions to the
Blessed Sacrament,
and the veneration of
saintly images such as the ''
santos''. The bishops at the Second Vatican Council reminded Catholics that "devotions should be so drawn up that they harmonize with the liturgical seasons, accord with the sacred liturgy, are in some fashion derived from it, and lead the people to it, since, in fact, the liturgy by its very nature far surpasses any of them."
Virgin Mary
Catholic Mariology deals with the
dogmas and teachings concerning the life of
Mary, mother of Jesus
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 ...
, as well as the veneration of Mary by the faithful. Mary is held in special regard, declared the
Mother of God (), and believed as dogma to have remained a
virgin throughout her life.
Further teachings include the doctrines of the
Immaculate Conception (her own conception without the stain of original sin) and the
Assumption of Mary (that her body was assumed directly into heaven at the end of her life). Both of these doctrines were defined as infallible dogma, by
Pope Pius IX in 1854 and
Pope Pius XII in 1950 respectively,
[Barry, p. 106] but only after consulting with the Catholic bishops throughout the world to ascertain that this is a Catholic belief. In the Eastern Catholic churches, however, they continue to celebrate the feast of the Assumption under the name of the
Dormition of the Mother of God on the same date. The teaching that Mary died before being assumed significantly precedes the idea that she did not. St John Damascene wrote that "St Juvenal, Bishop of Jerusalem, at the Council of Chalcedon (451), made known to the Emperor Marcian and Pulcheria, who wished to possess the body of the Mother of God, that Mary died in the presence of all the Apostles, but that her tomb, when opened, upon the request of St Thomas, was found empty; wherefrom the Apostles concluded that the body was taken up to Heaven."
Devotions to Mary are part of Catholic piety but are distinct from the worship of God. Practices include prayers and

. Several
liturgical Marian feasts are celebrated throughout the
Church Year and she is honoured with
many titles such as
Queen of Heaven.
Pope Paul VI called her
Mother of the Church because, by giving birth to Christ, she is considered to be the spiritual mother to each member of the
Body of Christ.
Because of her influential role in the life of Jesus, prayers and devotions such as the
Hail Mary, the
Rosary, the
Salve Regina and the
Memorare are common Catholic practices.
Pilgrimage to the sites of several
Marian apparitions affirmed by the church, such as
Lourdes,
Fátima, and
Guadalupe, are also popular Catholic devotions.
Sacraments
The Catholic Church teaches that it was entrusted with seven sacraments that were instituted by Christ. The number and nature of the sacraments were defined by several
ecumenical councils, most recently the Council of Trent.
These are
Baptism,
Confirmation, the
Eucharist,
Penance,
Anointing of the Sick (formerly called Extreme Unction, one of the "
Last Rites"),
Holy Orders and
Holy Matrimony. Sacraments are visible rituals that Catholics see as signs of God's presence and effective channels of God's
grace to all those who receive them with the proper disposition (''
ex opere operato''). The ''
Catechism of the Catholic Church'' categorizes the sacraments into three groups, the "sacraments of Christian initiation", "sacraments of healing" and "sacraments at the service of communion and the mission of the faithful". These groups broadly reflect the stages of people's natural and spiritual lives which each sacrament is intended to serve.
The liturgies of the sacraments are central to the church's mission. According to the ''Catechism'':
According to church doctrine, the sacraments of the church require the proper form, matter, and intent to be validly celebrated. In addition, the
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 ...
s for both the Latin Church and the Eastern Catholic Churches govern who may licitly celebrate certain sacraments, as well as strict rules about who may receive the sacraments.
Notably, because the church teaches that Christ is
present in the Eucharist,
[Kreeft, p. 326] those who are conscious of being in a state of mortal sin are forbidden to receive the sacrament until they have received absolution through the
sacrament of Reconciliation (Penance).
Catholics are normally obliged to abstain from eating for at least an hour before receiving the sacrament.
[Kreeft, p. 331] Non-Catholics are ordinarily prohibited from receiving the Eucharist as well.
Catholics, even if they were in danger of death and unable to approach a Catholic minister, may not ask for the sacraments of the Eucharist, penance or anointing of the sick from someone, such as a Protestant minister, who is not known to be validly ordained in line with Catholic teaching on ordination. Likewise, even in grave and pressing need, Catholic ministers may not administer these sacraments to those who do not manifest Catholic faith in the sacrament. In relation to the churches of Eastern Christianity not in communion with the Holy See, the Catholic Church is less restrictive, declaring that "a certain ''communion in sacris'', and so in the Eucharist, given suitable circumstances and the approval of Church authority, is not merely possible but is encouraged."
Sacraments of initiation
Baptism
As viewed by the Catholic Church, Baptism is the first of three sacraments of initiation as a Christian. It washes away all sins, both
original sin and personal actual sins. It makes a person a member of the church. As a gratuitous gift of God that requires no merit on the part of the person who is baptized, it is
conferred even on children, who, though they have no personal sins, need it on account of original sin.
If a new-born child is in a danger of death, anyone—be it a doctor, a nurse, or a parent—may baptize the child. Baptism marks a person permanently and cannot be repeated. The Catholic Church recognizes as valid baptisms conferred even by people who are not Catholics or Christians, provided that they intend to baptize ("to do what the Church does when she baptizes") and that they use the
Trinitarian baptismal formula.
Confirmation
The Catholic Church sees the sacrament of confirmation as required to complete the grace given in baptism. When adults are baptized, confirmation is normally given immediately afterwards,
a practice followed even with newly baptized infants in the Eastern Catholic Churches.
In the West confirmation of children is delayed until they are old enough to understand or at the bishop's discretion.
In Western Christianity, particularly Catholicism, the sacrament is called ''confirmation'', because it confirms and strengthens the grace of baptism; in the Eastern Churches, it is called ''chrismation'', because the essential rite is the anointing of the person with
chrism,
a mixture of
olive oil
Olive oil is a vegetable oil obtained by pressing whole olives (the fruit of ''Olea europaea'', a traditional Tree fruit, tree crop of the Mediterranean Basin) and extracting the oil.
It is commonly used in cooking for frying foods, as a cond ...
and some perfumed substance, usually
balsam, blessed by a bishop.
Those who receive confirmation must be in a state of grace, which for those who have reached the
age of reason means that they should first be cleansed spiritually by the sacrament of Penance; they should also have the intention of receiving the sacrament, and be prepared to show in their lives that they are Christians.
Eucharist
For Catholics, the Eucharist is the sacrament which completes Christian initiation. It is described as "the source and summit of the Christian life". The ceremony in which a Catholic first receives the Eucharist is known as
First Communion.
The Eucharistic celebration, also called the
Mass or
Divine liturgy, includes prayers and scriptural readings, as well as an offering of bread and wine, which are brought to the
altar and
consecrated by the priest to become the body and the blood of Jesus Christ, a change called
transubstantiation.
[For an outline of the Eucharistic liturgy in the Roman Rite, see the side bar in the "Worship and liturgy".] The
words of consecration reflect the words spoken by Jesus during the
Last Supper, where Christ offered his body and blood to his Apostles the night before his crucifixion. The sacrament re-presents (makes present) the sacrifice of Jesus on the cross, and perpetuates it. Christ's death and resurrection give grace through the sacrament that unites the faithful with Christ and one another, remits venial sin, and aids against committing moral sin (though mortal sin itself is forgiven through the sacrament of penance).
Sacraments of healing
The two sacraments of healing are the
Sacrament of Penance and
Anointing of the Sick.
Penance
The Sacrament of Penance (also called Reconciliation, Forgiveness, Confession, and Conversion) exists for the conversion of those who, after baptism, separate themselves from Christ by sin. Essential to this sacrament are acts both by the sinner (examination of conscience, contrition with a determination not to sin again, confession to a priest, and performance of some act to repair the damage caused by sin) and by the priest (determination of the act of reparation to be performed and
absolution).
Serious sins (
mortal sins) should be confessed at least once a year and always before receiving Holy Communion, while confession of
venial sins also is recommended. The priest is bound under the severest penalties to maintain the "
seal of confession", absolute secrecy about any sins revealed to him in confession.
Anointing of the sick

While chrism is used only for the three sacraments that cannot be repeated, a different oil is used by a priest or bishop to bless a Catholic who, because of illness or old age, has begun to be in danger of death. This sacrament, known as Anointing of the Sick, is believed to give comfort, peace, courage and, if the sick person is unable to make a confession, even forgiveness of sins.
The sacrament is also referred to as ''Unction'', and in the past as ''Extreme Unction'', and it is one of the three sacraments that constitute the
last rites, together with Penance and
Viaticum (Eucharist).
Sacraments at the service of communion
According to the Catechism, there are two sacraments of
communion directed towards the salvation of others: priesthood and marriage. Within the general vocation to be a Christian, these two sacraments "consecrate to specific mission or
vocation among the people of God. Men receive the holy orders to feed the Church by the word and
grace. Spouses marry so that their love may be fortified to fulfil duties of their state".
Holy Orders

The sacrament of Holy Orders consecrates and deputes some Christians to serve the whole body as members of three degrees or orders: episcopate (bishops), presbyterate (priests) and diaconate (deacons).
[ (As modified by the 200]
motu proprio
'' Omnium in mentem'') The church has defined rules on who may be ordained into the
clergy. In the Latin Church, the priesthood is generally restricted to celibate men, and the episcopate is always restricted to celibate men. Men who are already married may be ordained in certain Eastern Catholic churches in most countries, and the personal ordinariates and may become deacons even in the Latin Church
[Canon 1031](_blank)
Catholic Church Canon Law. Retrieved 9 March 2008.[Canon 1037](_blank)
, Catholic Church Canon Law. Retrieved 9 March 2008. (see
Clerical marriage). After becoming a Catholic priest, a man may not marry (see
Clerical celibacy) unless he is formally laicized.
All clergy, whether deacons, priests or bishops, may preach, teach, baptize, witness marriages and conduct funeral liturgies. Only bishops and priests can administer the sacraments of the Eucharist, Reconciliation (Penance) and Anointing of the Sick. Only bishops can administer the sacrament of Holy Orders, which
ordains someone into the clergy.
[Barry, p. 114.]
Matrimony

The Catholic Church teaches that marriage is a social and spiritual bond between a man and a woman, ordered towards the good of the spouses and procreation of children; according to Catholic teachings on sexual morality, it is the only appropriate context for sexual activity. A Catholic marriage, or any marriage between baptized individuals of any Christian denomination, is viewed as a sacrament. A sacramental marriage, once consummated, cannot be dissolved except by death. The church recognizes certain
conditions, such as freedom of consent, as required for any marriage to be valid; In addition, the church sets specific rules and norms, known as
canonical form, that Catholics must follow.
The church does not recognize divorce as ending a valid marriage and allows state-recognized divorce only as a means of protecting the property and well-being of the spouses and any children. However, consideration of particular cases by the competent ecclesiastical tribunal can lead to declaration of the invalidity of a marriage, a declaration usually referred to as an
annulment. Remarriage following a divorce is not permitted unless the prior marriage was declared invalid.
Liturgy

Among the 24 autonomous (''
sui iuris'') churches, numerous liturgical and other traditions exist, called rites, which reflect historical and cultural diversity rather than differences in belief. In the definition of the
Code of Canons of the Eastern Churches, "a rite is the liturgical, theological, spiritual, and disciplinary patrimony, culture and circumstances of history of a distinct people, by which its own manner of living the faith is manifested in each Church ''sui iuris''".
["''CCEO'', Canon 28 § 1"](_blank)
Vatican.va
). Intratext.com (English translation). 1990. Excerpt: "''Ritus est patrimonium liturgicum, theologicum, spirituale et disciplinare cultura ac rerum adiunctis historiae populorum distinctum, quod modo fidei vivendae uniuscuiusque Ecclesiae sui iuris proprio exprimitur''." (A rite is the liturgical, theological, spiritual and disciplinary heritage, differentiated by peoples' culture and historical circumstances, that finds expression in each ''sui iuris'' Church's own way of living the faith).
The liturgy of the sacrament of the
Eucharist, called the
Mass in the West and
Divine Liturgy or other names in the East, is the principal liturgy of the Catholic Church. This is because it is considered the propitiatory sacrifice of Christ himself. Its most widely used form is that of the
Roman Rite as promulgated by
Paul VI in 1969 (see
Missale Romanum) and revised by
Pope John Paul II
Pope John Paul II (born Karol Józef Wojtyła; 18 May 19202 April 2005) was head of the Catholic Church and sovereign of the Vatican City State from 16 October 1978 until Death and funeral of Pope John Paul II, his death in 2005.
In his you ...
in 2002 (see
Liturgiam Authenticam). In certain circumstances, the
1962 form of the Roman Rite remains authorized in the Latin Church. Eastern Catholic Churches have their own rites. The liturgies of the Eucharist and the other sacraments vary from rite to rite, reflecting different theological emphases.
Western rites
The Roman Rite is the most common
rite of worship used by the Catholic Church, with the
Ordinary Form of the Roman Rite form of the Mass. Its use is found worldwide, originating in Rome and spreading throughout Europe, influencing and eventually supplanting local rites. The present ordinary form of Mass in the Roman Rite, found in the post-1969 editions of the
Roman Missal, is usually celebrated in the local
vernacular language, using an officially approved translation from the original text in
Latin
Latin ( or ) is a classical language belonging to the Italic languages, Italic branch of the Indo-European languages. Latin was originally spoken by the Latins (Italic tribe), Latins in Latium (now known as Lazio), the lower Tiber area aroun ...
. An outline of its major liturgical elements can be found in the sidebar.
In 2007, Pope Benedict XVI affirmed the licitness of continued use of the
1962 Roman Missal as an "extraordinary form" (''forma extraordinaria'') of the Roman Rite, speaking of it also as an ''usus antiquior'' ("older use"), and issuing new more permissive norms for its employment. An instruction issued four years later spoke of the two forms or usages of the Roman Rite approved by the pope as the ordinary form and the extraordinary form ("the ''forma ordinaria''" and "the ''forma extraordinaria''").
The 1962 edition of the Roman Missal, published a few months before the
Second Vatican Council opened, was the last that presented the Mass as standardized in 1570 by
Pope Pius V at the request of the
Council of Trent and that is therefore known as the Tridentine Mass.
Pope Pius V's Roman Missal was subjected to minor revisions by
Pope Clement VIII
Pope Clement VIII (; ; 24 February 1536 – 3 March 1605), born Ippolito Aldobrandini, was head of the Catholic Church and ruler of the Papal States from 30 January 1592 to his death in March 1605.

in 1604,
Pope Urban VIII in 1634,
Pope Pius X in 1911,
Pope Pius XII in 1955, and
Pope John XXIII in 1962. Each successive edition was the ordinary form of the Roman Rite Mass until superseded by a later edition.
When the 1962 edition was superseded by that of Paul VI, promulgated in 1969, its continued use at first required permission from bishops.
Pope Benedict XVI's 2007
motu proprio ''
Summorum Pontificum'' allowed free use of it for Mass celebrated without a congregation and authorized parish priests to permit, under certain conditions, its use even at public Masses. Except for the scriptural readings, which Pope Benedict allowed to be proclaimed in the vernacular language, it is celebrated exclusively in
liturgical Latin. These permissions were largely removed by Pope Francis in 2021, who issued the ''motu proprio'' ''
Traditionis custodes'' to emphasize the Ordinary Form as promulgated by Popes Paul VI and John Paul II.
Since 2014, clergy in the small
personal ordinariates set up for groups of former Anglicans under the terms of the 2009 document ''
Anglicanorum Coetibus''
are permitted to use a variation of the Roman Rite called "Divine Worship" or, less formally, "Ordinariate Use", which incorporates elements of the
Anglican liturgy and traditions,
[The Divine Worship variant of the Roman Rite differs from the "Anglican Use" variant, which was introduced in 1980 for the few United States parishes established in accordance with a pastoral provision for former members of the Episcopal Church (the American branch of the Anglican Communion). Both uses adapted Anglican liturgical traditions for use within the Catholic Church.] an accommodation protested by Anglican leaders.
In the
Archdiocese of Milan, with around five million Catholics the largest in Europe, Mass is celebrated according to the
Ambrosian Rite. Other
Latin Church rites include the
Mozarabic and those of some religious institutes. These liturgical rites have an antiquity of at least 200 years before 1570, the date of Pope Pius V's ''
Quo primum'', and were thus allowed to continue.
Eastern rites

The Eastern Catholic Churches share common patrimony and liturgical rites as their counterparts, including
Eastern Orthodox and other
Eastern Christian churches who are no longer in communion with the Holy See. These include churches that historically developed in Russia, Caucasus, the Balkans, North Eastern Africa, India and the Middle East. The Eastern Catholic Churches are groups of faithful who have either never been out of communion with the Holy See or who have restored communion with it at the cost of breaking communion with their associates of the same tradition.
The
liturgical rites of the Eastern Catholic Churches include the
Byzantine Rite (in its Antiochian, Greek and Slavonic
recensions), the
Alexandrian Rite, the
West Syrian Rite, the
Armenian Rite, and the
East Syriac Rite. Eastern Catholic Churches have the autonomy to set the particulars of their liturgical forms and worship, within certain limits to protect the "accurate observance" of their liturgical tradition.
In the past, some of the rites used by the Eastern Catholic Churches were subject to a degree of
liturgical Latinization. In recent years Eastern Catholic Churches have returned to traditional Eastern practices in accord with the 1964
Vatican II decree ''
Orientalium Ecclesiarum''. Each church has its own
liturgical calendar.
Social, moral and cultural issues
Catholic social teaching
Catholic social teaching, reflecting the concern Jesus showed for the impoverished, places a heavy emphasis on the
corporal works of mercy and the
spiritual works of mercy, namely the support and concern for the sick, the poor and the afflicted.
Church teaching calls for a preferential
option for the poor while canon law prescribes that "The Christian faithful are also obliged to promote
social justice and, mindful of the precept of the Lord, to assist the poor."
Its foundations are widely considered to have been laid by Pope Leo XIII's 1891 encyclical letter ''
Rerum novarum'' which upholds the rights and dignity of labour and the right of workers to form unions.
Social services

The Catholic Church is the largest non-government provider of education and medical services in the world.
In 2010, the Catholic Church's Pontifical Council for Pastoral Assistance to Health Care Workers said that the church manages 26% of health care facilities in the world, including hospitals, clinics, orphanages, pharmacies and centres for those with leprosy.
The church has always been involved in education, since the founding of the
first universities of Europe.
It runs and sponsors thousands of primary and secondary schools,
colleges and universities throughout the world
and operates the world's largest non-governmental school system.
Religious institutes for women have played a particularly prominent role in the provision of health and education services,
as with orders such as the
Sisters of Mercy,
Little Sisters of the Poor, the Missionaries of Charity, the
Sisters of St. Joseph of the Sacred Heart, the
Sisters of the Blessed Sacrament and the
Daughters of Charity of Saint Vincent de Paul. The Catholic nun
Mother Teresa of
Calcutta, India, founder of the Missionaries of Charity, was awarded the
Nobel Peace Prize in 1979 for her humanitarian work among India's poor. Bishop
Carlos Filipe Ximenes Belo won the same award in 1996 for "work towards a just and peaceful solution to the conflict in
East Timor".
The church is also actively engaged in international aid and development through organizations such as
Catholic Relief Services,
Caritas Internationalis,
Aid to the Church in Need, refugee advocacy groups such as the
Jesuit Refugee Service and community aid groups such as the
Saint Vincent de Paul Society.
Sexual morality
Chastity and marriage
Catholic teaching regarding sexuality calls for a practice of
chastity according to their state of life, with a focus on maintaining the spiritual and bodily integrity of the human person.
In the church's teaching, sexual activity should be reserved to married couples without artificial birth control; marriage is considered the only appropriate context
whether in a
sacramental marriage among Christians or in a
natural marriage where one or both spouses are unbaptized. Even in romantic relationships, particularly
engagement to marriage, partners are called to practise continence, in order to test mutual respect and fidelity.
Chastity in marriage requires, in particular, conjugal fidelity and protecting the fecundity of marriage. The couple must foster trust and honesty as well as spiritual and physical intimacy. Sexual activity must always be open to the transmission of new life; the church calls this the procreative significance. It must likewise always bring a couple together in love; the church calls this the unitive significance. Artificial
contraception and certain other
sexual practices are not permitted, although
natural family planning
Natural family planning (NFP) comprises the family planning methods approved by the Catholic Church and some Protestant denominations for both achieving and postponing or avoiding pregnancy. In accordance with the church's teachings regarding h ...
methods are permitted to provide healthy spacing between births, or to postpone children for a just reason.
Church teachings about sexuality have become an issue of increasing controversy in the Western world, especially after the close of the Second Vatican Council in the 1960s, due to changing cultural attitudes described as the
sexual revolution. Pope Francis said in 2015 that he is worried that the church has grown "obsessed" with issues such as abortion,
same-sex marriage and
contraception, and for prioritizing moral doctrines over helping the poor and marginalized.
Homosexuality
The Catholic Church also teaches that "homosexual acts" are "contrary to the natural law", "acts of grave depravity" and "under no circumstances can they be approved", but that persons experiencing homosexual tendencies must be accorded respect and dignity.
According to the ''
Catechism of the Catholic Church'',
This part of the ''Catechism'' was quoted by Pope Francis in a 2013 press interview in which he remarked, when asked about an individual:
This remark and others made in the same interview were seen as a change in the tone, but not in the substance of the teaching of the church, which includes opposition to
same-sex marriage.
Certain
dissenting Catholic groups, such as
DignityUSA,
oppose the position of the Catholic Church and seek to change it. The Catholic Church has banned all such groups from church property.
Orthodox Catholic groups, such as Building Catholic Futures, encourage parishes to incorporate celibate gay people into the church communities.
Divorce and declarations of nullity
Canon law makes no provision for divorce between baptized individuals, as a valid, consummated sacramental marriage is considered to be a lifelong bond. However, a declaration of nullity may be granted when the proof is produced that essential conditions for contracting a valid marriage were absent from the beginning—in other words, that the marriage was not valid due to some impediment. A declaration of nullity, commonly called an annulment, is a judgement on the part of an
ecclesiastical tribunal determining that a marriage was invalidly attempted.
Marriages among unbaptized individuals may be dissolved with papal permission under certain situations, such as a desire to marry a Catholic, under
Pauline or
Petrine privilege.
[Rev. Mark J. Gantley]
"Petrine or Pauline Privilege"
EWTN Global Catholic Network. 3 September 2004. Accessed 15 November 2014.
. 1983 Code of Canon Law. Catholicdoors.com. An attempt at remarriage following divorce without a declaration of nullity places "the remarried spouse ... in a situation of public and permanent adultery". An innocent spouse who lives in continence following divorce, or couples who live in continence following a civil divorce for a grave cause, do not sin.
Worldwide, diocesan tribunals completed over 49000 cases for nullity of marriage in 2006. Over the past 30 years about 55 to 70% of annulments have occurred in the United States. The growth in annulments has been substantial; in the United States, 27,000 marriages were annulled in 2006, compared to 338 in 1968. However, approximately 200,000 married Catholics in the United States divorce each year; 10 million total .

Contraception and abortion

should only take place between a man and woman who are married to each other, and should be without the use of
birth control or
contraception. In his encyclical ''
Humanae vitae''
(1968),
Pope Paul VI firmly rejected all artificial contraception, thus contradicting dissenters in the church who saw the
birth control pill as an ethically justifiable method of
contraception, though he permitted the regulation of births by means of natural family planning (NFP.) This teaching was continued especially by
John Paul II in his encyclical ', where he clarified the church's position on artificial contraception,
abortion and
euthanasia by condemning them as part of a "culture of death" and calling instead for a "
culture of life".
Many Western Catholics have voiced significant disagreement with the church's teaching on contraception. Overturning the church's teaching on this point features high on progressive agendas.
Catholics for Choice, a political lobbyist group that is not associated with the Catholic Church, stated in 1998 that 96% of U.S. Catholic women had used contraceptives at some point in their lives and that 72% of Catholics believed that one could be a good Catholic without obeying the church's teaching on birth control.
Use of natural family planning methods among United States Catholics purportedly is low, although the number cannot be known with certainty. As Catholic health providers are among the largest providers of services to patients with

worldwide, there is significant controversy within and outside the church regarding the use of condoms as a means of limiting new infections, as
condom use ordinarily constitutes prohibited contraceptive use.
Similarly, the Catholic Church opposes
artificial insemination regardless of whether it is homologous (from the husband) or heterologous (from a
donor) and
in vitro fertilization (IVF), saying that the artificial process replaces the love and conjugal act between a husband and wife. In addition, it opposes IVF because it might cause disposal of embryos; Catholics believe an embryo is an individual with a
soul who must be treated as such. For this reason, the church also opposes abortion.
The Catholic Church oppose all forms of
abortion procedures whose direct purpose is to destroy a
zygote

. The 1983 Code of Canon Law, 1983 ''Code of Canon Law'' imposes Latae sententiae, automatic (''latae sententiae'') Excommunication (Catholic Church), excommunication on Latin Church, Latin Catholics who actually procure an abortion, if they fulfill the conditions for being subject to such a sanction.
Due to the anti-abortion stance, some Catholics oppose receiving vaccines derived from fetal cells obtained via abortion. On 21 December 2020, and regarding COVID-19 vaccine, COVID-19 vaccination, the Congregation for the Doctrine of the Faith emitted a document stating that "it is morally acceptable to receive Covid-19 vaccines that have used cell lines from aborted fetuses in their research and production process" when no alternative vaccine is available, since "the moral duty to avoid such passive material cooperation is not obligatory if there is a grave danger, such as the otherwise uncontainable spread of a serious pathological agent."
The document states that receiving the vaccine does not constitute endorsement of the practice of abortion, and that "the morality of vaccination depends not only on the duty to protect one's own health, but also on the duty to pursue the common good."
The document cautions further:
Death penalty and euthanasia
The Catholic Church is committed to the worldwide abolition of the death penalty in any circumstance.
The current ''
Catechism of the Catholic Church'' teaches that "in the light of the
Gospel
Gospel originally meant the Christianity, Christian message ("the gospel"), but in the second century Anno domino, AD the term (, from which the English word originated as a calque) came to be used also for the books in which the message w ...
" the death penalty is "inadmissible because it is an attack on the inviolability and Human dignity, dignity of the person" and that the Catholic Church "works with determination for its abolition worldwide."
In his 2020 encyclical ''Fratelli tutti'', Francis repeated that the death penalty is "inadmissible" and that "there can be no stepping back from this position".
On 9 January 2022, Pope Francis stated in his annual speech to Vatican ambassadors: "The death penalty cannot be employed for a purported state justice, since it does not constitute a deterrent nor render justice to victims, but only fuels the thirst for vengeance".
There is controversy about whether the Catholic Church considers the death penalty intrinsically evil.
American Archbishop José Horacio Gómez
and Catholic philosopher Edward Feser argue that this is a matter of prudential judgement and that the church does not teach this as a ''de fide'' statement; others, such as Cardinals Charles Maung Bo and Rino Fisichella, state that it does.
The Catholic Church opposes active euthanasia and Assisted suicide, physician-assisted suicide on the grounds that life is a gift from God and should not be prematurely shortened. However, the church allows dying people to refuse Dysthanasia, extraordinary treatments that would minimally prolong life without hope of recovery.
Holy orders and women
Women and men religious engage in a variety of occupations such as contemplative prayer, teaching, providing health care, and working as missionaries.
Catholic Church and women, Catholic women have played diverse roles in the life of the church, with religious institutes providing a formal space for their participation and convents providing spaces for their self-government, prayer and influence through many centuries. Religious sisters and
nuns have been extensively involved in developing and running the church's worldwide health and education service networks.
Holy Orders are reserved for men. Efforts in support of the Catholic Church doctrine on the ordination of women, ordination of women to the priesthood led to several rulings by the Roman Curia or popes against the proposal, as in ''Inter Insigniores, Declaration on the Question of the Admission of Women to the Ministerial Priesthood'' (1976), ''Mulieris Dignitatem'' (1988) and ''Ordinatio sacerdotalis'' (1994). According to the latest ruling, found in ''Ordinatio sacerdotalis'',
Pope John Paul II
Pope John Paul II (born Karol Józef Wojtyła; 18 May 19202 April 2005) was head of the Catholic Church and sovereign of the Vatican City State from 16 October 1978 until Death and funeral of Pope John Paul II, his death in 2005.

affirmed that the Catholic Church "does not consider herself authorised to admit women to priestly ordination".
In defiance of these rulings, independent opposition groups such as Roman Catholic Womenpriests have performed ceremonies they affirm as sacramental ordinations, with, reputedly, an ordaining male Catholic bishop in the first few instances, which, according to
canon law

["Ordinations: Response Regarding Excommunication Decree"](_blank)
. 2011 Roman Catholic Womenpriests-USA, Inc. Retrieved 5 June 2011 The Congregation for the Doctrine of the Faith responded by issuing a statement clarifying that any Catholic bishops involved in ordination ceremonies for women, as well as the women themselves if they were Catholic, would automatically receive the penalty of excommunication (''latae sententiae'', literally "with the sentence already applied", i.e. automatically), citing canon 1378 of
canon law

and other church laws.
Sexual abuse cases
From the 1990s, the issue of sexual abuse of minors by Catholic clergy and other church members has become the subject of civil litigation, criminal prosecution, media coverage and public debate in Catholic Church sex abuse cases by country, countries around the world. The Catholic Church has been criticized for the way it handled abuse complaints when it became known that many bishops and various officials in the Church hierarchy had protected accused priests, transferring them to other assignments elsewhere, where they continued to commit sex crimes.
In response to the scandals, formal procedures have been established to help prevent abuse, encourage the reporting of any abuse that occurs and to handle such reports promptly, although groups representing victims have disputed their effectiveness. In 2014, Pope Francis instituted the Pontifical Commission for the Protection of Minors for the safeguarding of minors.
Environmental
The church has also addressed stewardship of the natural environment, and its relationship to other social and theological teachings. In the document , dated 24 May 2015, Pope Francis critiques consumerism and overdevelopment, irresponsible development, and laments environmental degradation and climate change.
The pope expressed concern that the warming of the planet is a symptom of a greater problem: the developed world's indifference to the destruction of the planet as humans pursue short-term economic gains.
