Anglican Communion in the context of Anglican religious order

Autocephaly (/ɔːtəˈsɛfəli/; from Greek αὐτοκεφαλία (autokephalia) 'self-headed') is the status of a hierarchical Christian church whose head bishop does not report to any higher-ranking bishop. The term is primarily used in Eastern Orthodox and Oriental Orthodox churches. The status has been compared with that of the churches (provinces) within the Anglican Communion.

In the history of Christianity, the first seven ecumenical councils are as follows: the First Council of Nicaea in 325, the First Council of Constantinople in 381, the Council of Ephesus in 431, the Council of Chalcedon in 451, the Second Council of Constantinople in 553, the Third Council of Constantinople from 680 to 681 and finally, the Second Council of Nicaea in 787.

These seven events represented an attempt by Church leaders to reach an orthodox consensus, restore peace and develop a unified Christendom. Among Eastern Christians the Eastern Orthodox, Oriental Orthodox, and Church of the East (Assyrian) churches and among Western Christians the Roman Catholic, Anglican, Utrecht and Polish National Old Catholic, and some Scandinavian Lutheran churches all trace the legitimacy of their clergy by apostolic succession back to this period and beyond, to the earlier period referred to as the Early Church.

The Four Marks of the Church, also known as the Attributes of the Church, describes four distinctive adjectives of traditional Christian ecclesiology as expressed in the Nicene Creed completed at the First Council of Constantinople in AD 381: "[We believe] in one, holy, catholic, and apostolic Church."

This ecumenical creed is today recited in the liturgies of the Eastern Orthodox Church, the Catholic Church (both Latin and Eastern Rites), the Oriental Orthodox Churches, the Assyrian Church of the East, the Moravian Church, the Lutheran Churches, the Methodist Churches, the Presbyterian Churches, the Anglican Communion, and by members of the Reformed Churches, although they interpret it in very different ways, and some Protestants alter the word "Catholic" in the creed, replacing it with the word "Christian".

The culture of the United Kingdom is influenced by its combined nations' history, its interaction with the cultures of Europe, the individual diverse cultures of England, Wales, Scotland and Northern Ireland, and the impact of the British Empire. The culture of the United Kingdom may also colloquially be referred to as British culture. Although British culture is a distinct entity, the individual cultures of England, Scotland, Wales and Northern Ireland are diverse. There have been varying degrees of overlap and distinctiveness between these four cultures. British literature is particularly esteemed. The modern novel was developed in Britain, and playwrights, poets, and authors are among its most prominent cultural figures. Britain has also made notable contributions to theatre, music, cinema, art, architecture and television. The UK is also the home of the Church of England, Church of Scotland, Church in Wales, the state church and mother church of the Anglican Communion, the third-largest Christian denomination. Britain contains some of the world's oldest universities, has made many contributions to philosophy, science, technology and medicine, and is the birthplace of many prominent scientists and inventions. The Industrial Revolution began in the UK and had a profound effect on socio-economic and cultural conditions around the world.

British culture has been influenced by historical and modern migration, the historical invasions of Great Britain, and the British Empire. As a result of the British Empire, significant British influence can be observed in the language, law, culture and institutions of its former colonies, most of which are members of the Commonwealth of Nations. A subset of these states form the Anglosphere, and are among Britain's closest allies. British colonies and dominions influenced British culture in turn, particularly British cuisine.

Flavia Julia Helena (/ˈhɛlənə/; Ancient Greek: Ἑλένη, Helénē; c. AD 246/248 – 330), also known as Helena of Constantinople and in Christianity as Saint Helena, was a Greek Augusta of the Roman Empire and mother of Emperor Constantine the Great. She was born in the lower classes traditionally in the city of Drepanon, Bithynia, in Asia Minor, which was renamed Helenopolis.

Helena ranks as an important figure in the history of Christianity. In her final years, she made a religious tour of Syria Palaestina and Jerusalem, during which ancient tradition claims that she discovered the True Cross. The Eastern Orthodox Church, Catholic Church, Oriental Orthodox Churches, Anglican Communion, and the Lutheran Church revere her as a saint.

Pentecost (also called Whit Sunday, Whitsunday or Whitsun) is a Christian holiday that takes place on the 49th day (50th day when inclusive counting is used) after Easter. It commemorates the descent of the Holy Spirit upon the Apostles of Jesus, Mary, and other followers of the Christ, while they were in Jerusalem celebrating the Feast of Weeks, as described in the Acts of the Apostles (Acts 2:1–31). Pentecost marks the "Birthday of the Church".

Pentecost is one of the Great feasts in the Eastern Orthodox Church, a Solemnity in the Roman Rite of the Catholic Church, a Festival in the Lutheran Churches, and a Principal Feast in the Anglican Communion. Many Christian denominations provide a special liturgy for this holy celebration. Since its date depends on the date of Easter, Pentecost is a "moveable feast". The Monday after Pentecost is a legal holiday in many European, African and Caribbean countries.

The Union of Utrecht of the Old Catholic Churches, most commonly referred to by the short form Union of Utrecht (UU), is a federation of Old Catholic churches, nationally organized from schisms which rejected Roman Catholic doctrines of the First Vatican Council in 1870; its member churches are not in communion with the Roman Catholic Church.

The 1889 Declaration of Utrecht is one of three founding documents together called the Convention of Utrecht. Many provinces of the Union of Utrecht of the Old Catholic Churches are members of the World Council of Churches. The UU is in full communion with the Evangelical Lutheran Church of Sweden; the Anglican Communion through the 1931 Bonn Agreement; the Philippine Independent Church, the Spanish Reformed Episcopal Church, and the Lusitanian Catholic Apostolic Evangelical Church through a 1965 extension of the Bonn Agreement; and, the Mar Thoma Syrian Church through the 2024 Thiruvalla agreement.

Anglicanism, also known as Episcopalianism in some countries, is a Western Christian tradition which developed from the practices, liturgy, and identity of the Church of England following the English Reformation, in the context of the Protestant Reformation in Europe. It is one of the largest branches of Christianity, with around 110 million adherents within the Anglican Communion, and more than 400,000 outside of the Anglican Communion, worldwide as of 2025.

Adherents of Anglicanism are called Anglicans; they are also called Episcopalians in some countries. Most are members of national or regional ecclesiastical provinces of the international Anglican Communion, one of the largest Christian bodies in the world, and the world's third-largest Christian communion. The provinces within the Anglican Communion have historically been in full communion with the See of Canterbury and thus with the archbishop of Canterbury, whom the communion refers to as its primus inter pares (Latin, 'first among equals'). The archbishop calls the decennial Lambeth Conference, chairs the meeting of primates, and is the president of the Anglican Consultative Council. Some churches that are not part of the Anglican Communion or recognised by it also call themselves Anglican, including those that are within the Continuing Anglican movement and Anglican realignment.

The Words of Institution, also called the Words of Consecration, are words echoing those of Jesus himself at his Last Supper that, when consecrating bread and wine, Christian eucharistic liturgies include in a narrative of that event. Eucharistic scholars sometimes refer to them simply as the verba (Latin for "words").

Almost all existing ancient Christian churches explicitly include the Words of Institution in their eucharistic celebrations and consider them necessary for the validity of the sacrament. This is the practice of the Catholic Church's Latin liturgical rites and Eastern Catholic liturgies, the Eastern Orthodox Church, and all the Oriental Orthodox Churches, including the Armenian, the Coptic, the Ethiopian and the Malankara, as well as the Anglican Communion, Lutheran churches, Methodist churches, and Reformed churches. The only ancient eucharistic ritual still in use that does not explicitly contain the Words of Institution is the Holy Qurbana of Addai and Mari, used for part of the year by the Church of the East denominations, namely Assyrian Church of the East, Ancient Church of the East, and the Chaldean Syrian Church, due to their tradition of using the Holy Leaven. The Chaldean Catholic Church and the Syro-Malabar Church, two of the Eastern Catholic Churches, use the same Anaphora, but insert in it the Words of Institution. However, groups authorized by the Catholic Church to review the Qurbana recognized the validity of this eucharistic celebration in its original form, without explicit mention of the Words of Institution, saying that "the words of Eucharistic Institution are indeed present in the Anaphora of Addai and Mari, not in a coherent narrative way and ad litteram, but rather in a dispersed euchological way, that is, integrated in successive prayers of thanksgiving, praise and intercession."

The Liturgical Movement was a 19th- and 20th-century movement of scholarship for the reform of worship. It began in the Catholic Church and spread to many other Christian churches including the Anglican Communion, Lutheran and some other Protestant churches.

Saint Cecilia (Latin: Sancta Caecilia), also spelled Cecelia, was a Roman Christian virgin martyr, who is venerated in Catholic, Orthodox, Anglican, and some Lutheran churches, such as the Church of Sweden. She became the patroness of music and musicians, it being written that, as the musicians played at her wedding, Cecilia "sang in her heart to the Lord". Musical compositions are dedicated to her, and her feast, on 22 November, is the occasion of concerts and musical festivals. She is also known as Cecilia of Rome.

Saint Cecilia is one of several virgin martyrs commemorated by name in the Canon of the Mass in the Latin Church. The church of Santa Cecilia in Trastevere, founded in the 3rd century by Pope Urban I, is believed to be on the site of the house where she lived and died.

Rowan Douglas Williams, Baron Williams of Oystermouth (born 14 June 1950), is a Welsh Anglican bishop, theologian and poet, who served as the 104th Archbishop of Canterbury from 2002 to 2012. Previously the Bishop of Monmouth and Archbishop of Wales, Williams was the first Archbishop of Canterbury in modern times not to be appointed from within the Church of England.

Williams's primacy was marked by speculation that the Anglican Communion (in which the Archbishop of Canterbury is the leading figure) was fragmenting over disagreements on contemporary issues such as homosexuality and the ordination of women. Williams worked to keep all sides in dialogue. Notable events during his time as Archbishop of Canterbury include the rejection by a majority of dioceses of his proposed Anglican Covenant and, in the final general synod of his tenure, his unsuccessful attempt to secure a sufficient majority for a measure to allow the appointment of women as bishops in the Church of England.

Saint Patrick (Latin: Pātricius; Irish: Pádraig Irish pronunciation: [ˈpˠɑːɾˠɪɟ] or Irish pronunciation: [ˈpˠaːd̪ˠɾˠəɟ]; Welsh: Padrig) was a fifth-century Romano-British Christian missionary and bishop in Ireland. Known as the "Apostle of Ireland", he is the primary patron saint of Ireland, the other patron saints being Brigid of Kildare and Columba. He is also the patron saint of Nigeria. Patrick was never formally canonised by the Catholic Church, having lived before the current laws were established for such matters. He is venerated as a saint in the Catholic Church, the Lutheran Church, the Church of Ireland (part of the Anglican Communion), and in the Eastern Orthodox Church, where he is regarded as equal-to-the-apostles and Enlightener of Ireland.

The dates of Patrick's life cannot be fixed with certainty, but there is general agreement that he was active as a missionary in Ireland during the fifth century. A recent biography on Patrick shows a late fourth-century date for the saint is possible. According to tradition dating from the early Middle Ages, Patrick was the first bishop of Armagh and Primate of Ireland, and is credited with bringing Christianity to Ireland (despite evidence of some earlier Christian presence on the island), and converting Ireland from paganism in the process.

The Church of Ireland (Irish: Eaglais na hÉireann, pronounced [ˈaɡlˠəʃ n̪ˠə ˈheːɾʲən̪ˠ]; Ulster-Scots: Kirk o Airlann, [kɪrk ə ˈerlən(d)]) is a Christian church in Ireland, and an autonomous member church of the Anglican Communion. It is organised on an all-Ireland basis and is the second-largest Christian church on the island after the Roman Catholic Church. Like other Anglican churches, it has retained elements of pre-Reformation practice, notably its episcopal polity, while rejecting the primacy of the pope.

In theological and liturgical matters, it incorporates many principles of the Reformation, particularly those of the English Reformation, but self-identifies as being both Reformed and Catholic, in that it sees itself as the inheritor of a continuous tradition going back to the founding of Christianity in Ireland. As with other members of the global Anglican Communion, individual parishes accommodate differing approaches to the level of ritual and formality, variously referred to as High and Low Church.

The Biblical apocrypha (from Ancient Greek ἀπόκρυφος (apókruphos) 'hidden') denotes the collection of ancient books, some of which are believed by some to be of doubtful origin, thought to have been written some time between 200 BC and 100 AD.

The Catholic, Eastern Orthodox and Oriental Orthodox churches include some or all of the same texts within the body of their version of the Old Testament, with Catholics terming them deuterocanonical books. Traditional 80-book Protestant Bibles include fourteen books in an intertestamental section between the Old Testament and New Testament called the Apocrypha, deeming these useful for instruction, but non-canonical. Reflecting this view, the lectionaries of the Lutheran Churches and Anglican Communion include readings from the Apocrypha.
