Anglican Communion

Imagine a global family of churches, united by shared heritage yet fiercely independent—that's the Anglican Communion. Spanning continents, it connects tens of millions of people through a distinct spiritual tradition that blends Catholic and Reformed influences. This remarkable network, centered symbolically on the Archbishop of Canterbury, navigates both deep unity and profound disagreements, revealing the vibrant, complex tapestry of modern Christianity. The Anglican Communion is a global network of independent churches, uniquely unified by history and shared worship rather than a central governing authority. Rooted in the English Reformation, Anglicanism spread worldwide through the British Empire, adapting and evolving into distinct national churches. Despite its unifying 'instruments of communion,' the global body faces ongoing theological and social controversies, particularly regarding human sexuality, leading to significant internal tensions and realignments.

AI Summary

Imagine a global family of churches, united by shared heritage yet fiercely independent—that's the Anglican Communion. Spanning continents, it connects tens of millions of people through a distinct spiritual tradition that blends Catholic and Reformed influences. This remarkable network, centered symbolically on the Archbishop of Canterbury, navigates both deep unity and profound disagreements, revealing the vibrant, complex tapestry of modern Christianity.

The Anglican Communion: A Global Family

At its heart, the Anglican Communion is a vast Christian family, bringing together the historic Church of England with a host of other national and regional churches across the globe. What binds them isn't a central command, but a shared spiritual identity and full communion—meaning they recognize each other's sacraments and ministry.

This makes it one of the largest Christian communions worldwide, boasting between 85 and 110 million members. It stands as the third or fourth largest, after the Roman Catholic and Eastern Orthodox Churches, and potentially the World Communion of Reformed Churches.

The Archbishop of Canterbury, based in England, holds a unique position within this family. He is recognized as 'primus inter pares'—or 'first among equals'—serving as a symbolic focus of unity. However, this role is primarily spiritual and consultative; he holds no direct authority over Anglican provinces outside of the Church of England itself.

Officially formalized at the Lambeth Conference in London in 1867, the churches of the Communion see themselves as part of the 'one, holy, catholic and apostolic church.' Their worship is deeply shaped by the 'Book of Common Prayer,' while Anglican doctrine finds its traditional roots in the Thirty-nine Articles and The Books of Homilies.

A Broad Spectrum of Belief

Anglicanism embraces a broad spectrum of beliefs and practices, often described through traditions like Evangelical, Central, and Anglo-Catholic. It's a space where Reformed Protestant perspectives coexist with Arminian theological viewpoints. Many adherents see Anglicanism as a distinct form of Reformed Protestantism, or even a 'via media'—a middle way—between Lutheranism and Calvinism, embodying elements of both Catholic and Reformed Christianity.

Crucially, each national or regional church within the Communion operates with complete independence. They maintain their own legislative processes and episcopal polity, meaning they are governed by bishops and local primates. This autonomy is a defining characteristic, fostering diverse expressions of faith within the overarching Anglican identity.

The English Roots of a Global Church

The journey of the Anglican Communion begins with the Church of England itself, which formally separated from the Roman Catholic Church in 1534 under Henry VIII. After a brief reunion under Mary I, the final separation came in 1570 with Elizabeth I, who was subsequently excommunicated.

The Church of England never saw itself as a new creation, but rather as a reformed continuation of the ancient 'English Church'—or 'Ecclesia Anglicana.' This distinctly national phenomenon eventually spread far beyond England's shores, often hand-in-hand with the expansion of the British Empire.

Missionary organizations like the Society for Promoting Christian Knowledge (1698) and the Society for the Propagation of the Gospel in Foreign Parts (1701) played pivotal roles in carrying Anglicanism to the farthest corners of the world. As the Empire grew, so did the reach of the 'English Church.'

From Colonies to Autonomous Provinces

Initially, colonial churches fell under the jurisdiction of the Bishop of London. But with movements like the American Revolution, these fledgling churches began to assert their independence. The Episcopal Church in the United States, for instance, amicably broke away from a church whose supreme governor was the British monarch, forming its own national identity.

Following this, the Church of England began appointing colonial bishops in other territories—the first Bishop of Nova Scotia in 1787, then Calcutta, the West Indies, and Australia. This gradual process laid the groundwork for the establishment of independent dioceses and, eventually, self-governing provinces.

By the mid-19th century, a crucial shift occurred: a ruling in 1861 declared that, unless specifically established by law, the Church of England in the colonies held the same legal standing as any other church. This paved the way for local appointments of bishops and the formation of national synods capable of passing their own ecclesiastical legislation, independent of England.

Lambeth Conferences: A Unifying Force

A defining moment in the Communion's development was the advent of the Lambeth Conferences. First convened in 1867, these gatherings brought together bishops from disparate churches to discuss mutual concerns and demonstrate their unity. Importantly, the conferences agreed only to pass advisory resolutions, respecting the autonomy of each emerging province.

Held roughly every ten years, these conferences became the most visible expression of the entire Communion coming together. They showcased how unity could be maintained through shared collegiality and dialogue, even without universal legal ties.

The 1998 Lambeth Conference marked a significant turning point, especially concerning discussions on human sexuality. For the first time in centuries, the voices of bishops from developing regions—particularly Africa, Asia, and Latin America—gained prominence, challenging the perspectives of more prosperous Western churches. Many observers consider this conference a watershed moment, signaling a shift in global Christianity's center of gravity.

Contemporary Controversies and Divides

The Communion's decentralized structure, while fostering diversity, has also led to significant differences of opinion and occasional conflicts. These disputes often arise over liturgical practices and, increasingly, social issues, intensifying as Anglicanism spread across diverse cultures.

Ordination of Women

One such area of debate has been the role of women in ministry. The late 1970s saw the emergence of the 'Continuing Anglican movement,' which formed new church bodies in opposition to women's ordination and prayer book changes. Today, while two-thirds of Anglican provinces ordain women as deacons, priests, and bishops, others maintain different stances, reflecting the ongoing diversity within the Communion.

Ethical Stances: Abortion and Euthanasia

On matters of life and death, the Lambeth Conferences have consistently upheld a conservative position. Resolutions from 1930, 1958, and 1978 expressed an "abhorrence of the sinful practice of abortion," affirming that "the sacredness of life is, in Christian eyes, an absolute." Similarly, the 1998 conference affirmed the "intrinsic sanctity" of life in the context of debates around euthanasia and assisted suicide.

Same-Sex Unions and LGBT Clergy

More recently, disagreements over human sexuality have profoundly strained the Communion's unity. The consecration of an openly gay bishop in the US in 2003 led to the formation of the Anglican Church in North America. Subsequent decisions by the Church of England in 2023 to authorize blessings for same-sex couples, and in 2024 to support clergy entering civil same-sex marriages, have deepened these divisions.

This has led to a notable 'realignment' within the Communion. While some provinces in developed countries have adopted more liberal stances, conservative Anglican churches, particularly in the Global South, have strongly opposed these changes. In 2023, ten provinces and allied churches declared 'impaired communion' with the Church of England, and no longer recognize the Archbishop of Canterbury as 'first among equals,' though they stated they intend to remain within the Anglican Communion.

The Threads That Bind: Ecclesiology and Ethos

Despite its lack of a central legal authority, the Anglican Communion remains united by a deep, shared history, expressed through its 'ecclesiology'—the understanding of the church—its 'polity'—how it's governed—and its overarching 'ethos'—its characteristic spirit. The Anglican Communion Office, under the Archbishop of Canterbury, serves a supporting role, but holds no legislative power.

Three pillars fundamentally hold the Communion together: first, the shared episcopal polity, maintained through the apostolic succession of bishops and synodical government. Second, belief expressed through worship, giving immense importance to approved prayer books. And third, the foundational historical documents and the influential writings of early Anglican theologians.

The Book of Common Prayer and 'Lex Orandi'

Unlike some denominations that rely on a single founding theologian or a detailed confessional statement, Anglicanism's theological identity is largely shaped by its vernacular prayer book, the 'Book of Common Prayer.' This has given rise to the principle of 'lex orandi, lex credendi'—'the law of praying is the law of believing'—meaning that worship itself defines belief.

The Chicago-Lambeth Quadrilateral

A key resolution from the 1888 Lambeth Conference, known as the Chicago-Lambeth Quadrilateral, laid out four essential principles that continue to define Anglican identity and serve as a basis for ecumenical dialogue. These principles identify the foundational elements of faith shared across the Communion.

These four points serve as a concise summary of what Anglicans hold to be essential to the Church. They represent a bedrock for understanding both Anglicanism's unique character and its potential for unity with other Christian traditions.

The Holy Scriptures as the ultimate standard of faith. The Apostles' and Nicene Creeds as sufficient statements of Christian faith. The two Sacraments ordained by Christ: Baptism and the Lord's Supper. The Historic Episcopate, adapted to local needs.

Instruments of Communion

While there is no single international governing body, the Anglican Communion is held together by four 'instruments of communion'—consultative and collaborative bodies in which all member churches participate. Their resolutions are advisory, but they provide vital forums for discussion, mutual support, and maintaining unity.

Together, these instruments help navigate the complexities of a globally diverse church, ensuring that despite its independent parts, the Anglican Communion strives to move forward as one, albeit often challenging, family.

The Archbishop of Canterbury, as the spiritual head and focus of unity. The Lambeth Conference, a decennial gathering of all bishops for discussion and advisory resolutions. The Anglican Consultative Council, meeting every few years with bishops, clergy, and laity from all provinces. The Primates' Meeting, a more recent forum for the leading bishops (primates) of each province to engage in 'leisurely thought, prayer, and deep consultation.'

Article

Anglican Communion

The Anglican Communion (AC) is a Christian communion consisting of the autocephalous national and regional churches historically in full communion with the Archbishop of Canterbury. Member churches exercise jurisdictional independence but share a common heritage concerning Anglican identity and commitment to scripture, tradition, and reason as sources of authority. The Archbishop of Canterbury acts as a focus of unity, recognised as primus inter pares ("first among equals"), but without formal authority in Anglican provinces outside of the Church of England. Most, but not all, member churches of the communion are the historic national or regional Anglican churches.

With approximately 85–110 million members in 2025, among its 47 member churches, it is the third or fourth largest Christian communion of churches globally, after the Catholic, Eastern Orthodox, and, possibly, World Communion of Reformed Churches. In 2021, excluding the United and Uniting churches, research published in the World Christian Database estimated that the Anglican Communion had approximately 97,399,000 members. The Anglican Communion considers baptism to be "the traditional gauge" or definition for membership.

The Anglican Communion was officially and formally organised and recognised as such at the Lambeth Conference in 1867 in London under the leadership of Charles Longley, Archbishop of Canterbury. The churches of the Anglican Communion consider themselves to be part of the one, holy, catholic and apostolic church, with their liturgy based on the Book of Common Prayer. The traditional origins of Anglican doctrine are summarized in the Thirty-nine Articles (1571) and The Books of Homilies.

As in the Church of England itself, the Anglican Communion includes the broad spectrum of beliefs and liturgical practises found in the Evangelical, Central and Anglo-Catholic traditions of Anglicanism; both the larger Reformed Anglican and the smaller Arminian Anglican theological perspectives have been represented. Each national or regional church is fully independent, retaining its own legislative process and episcopal polity under the leadership of a local primate. For many adherents, Anglicanism represents a distinct form of Reformed Protestantism that emerged under the influence of the Reformer Thomas Cranmer; for others, it is a via media between two branches of Protestantism—Lutheranism and Calvinism; or for yet others, it is a denomination that is both Catholic and Reformed. Full participation in the sacramental life of each church is available to all communicant members.

Most members of the churches of the Anglican Communion live in the Anglosphere: a group of dozens of countries and regions that are predominantly English-speaking, often former British colonies or territories, many of which still voluntarily associate as members of the Commonwealth. Because of their historical link to England (ecclesia anglicana means "English church"), some of the member churches are known as "Anglican", such as the Anglican Church of Canada. Others, for example the Church of Ireland and the Scottish Episcopal and American Episcopal churches, have official names that do not include "Anglican". Conversely, some churches that do use the name "Anglican" are not part of the communion. These have generally disaffiliated over disagreement with the progress and direction of the broader Communion.

History

Anglican Communion

The Anglican Communion traces much of its growth to the older mission organisations of the Church of England such as the Society for Promoting Christian Knowledge (founded 1698), the Society for the Propagation of the Gospel in Foreign Parts (founded 1701) and the Church Missionary Society (founded 1799). The Church of England (which until the 20th century included the Church in Wales) initially separated from the Roman Catholic Church in 1534 in the reign of Henry VIII, reunited briefly in 1555 under Mary I and then separated again in 1570 under Elizabeth I (the Roman Catholic Church excommunicated Elizabeth I in 1570 in response to the Act of Supremacy 1559).

The Church of England has always thought of itself not as a new foundation but rather as a reformed continuation of the ancient "English Church" (Ecclesia Anglicana) and a reassertion of that church's rights. As such it was a distinctly national phenomenon. The Church of Scotland was formed as a separate church from the Roman Catholic Church as a result of the Scottish Reformation in 1560 and the later formation of the Scottish Episcopal Church began in 1582 (in the reign of James VI) over disagreements about the role of bishops.

The Church of England was the established church not only in England, but in its trans-Oceanic colonies. Thus the only member churches of the present Anglican Communion existing by the mid-18th century were the Church of England, its closely linked sister church the Church of Ireland (which also separated from Roman Catholicism under Henry VIII) and the Scottish Episcopal Church which for parts of the 17th and 18th centuries was partially underground (it was suspected of Jacobite sympathies).

The oldest-surviving Anglican church building outside the British Isles is St Peter's Church in St. George's, Bermuda, established in 1612 (though the actual building had to be rebuilt several times over the following century). This is also the oldest surviving non-Roman Catholic church in the New World. It remained part of the Church of England until 1978 when the Anglican Church of Bermuda was formed.

Global spread of Anglicanism

Anglican confirmation at the Mikael Agricola Church in Helsinki, Finland, in June 2013

The enormous expansion in the 18th and 19th centuries of the British Empire brought Anglicanism along with it. At first all these colonial churches were under the jurisdiction of the bishop of London. After the American Revolution, the parishes in the newly independent United States found it necessary to break formally from a church whose supreme governor was (and remains) the British monarch. Thus they formed their own dioceses and national church, the Episcopal Church in the United States of America, in a mostly amicable separation.

At about the same time, in the colonies which remained linked to the crown, the Church of England began to appoint colonial bishops. In 1787, Charles Inglis (Bishop of Nova Scotia) was appointed with jurisdiction over all of British North America; in time several more colleagues were appointed to sees in other provinces in present-day Canada. In 1814, a bishop of Calcutta was appointed. In 1824 the first bishop was sent to the West Indies. And in 1836 Australia received its first Anglican bishop. By 1840 there were still only ten colonial bishops in the Church of England; but this small beginning quickly facilitated the growth of Anglicanism around the world. In 1841, a "Colonial Bishoprics Council" was set up and soon many more dioceses were created.

In time, it became natural to group these into provinces and a metropolitan bishop was appointed for each province. Although it had at first been somewhat established in many colonies, in 1861 it was ruled that, except where specifically established, the Church of England had just the same legal position as any other church. Thus a colonial bishop and colonial diocese was by nature quite a different thing from their counterparts back home. In time bishops came to be appointed locally rather than from England and eventually national synods began to pass ecclesiastical legislation independent of England.

A crucial step in the development of the modern communion was the idea of the Lambeth Conferences (discussed above). These conferences demonstrated that the bishops of disparate churches could manifest the unity of the church in their episcopal collegiality despite the absence of universal legal ties. Some bishops were initially reluctant to attend, fearing that the meeting would declare itself a council with power to legislate for the church; but it agreed to pass only advisory resolutions. These Lambeth Conferences have been held roughly every ten years since 1878 (the second such conference) and remain the most visible coming-together of the whole communion.

The Lambeth Conference of 1998 included what has been seen by Philip Jenkins and others as a "watershed in global Christianity". The 1998 Lambeth Conference considered the issue of the theology of same-sex attraction in relation to human sexuality. At this 1998 conference, for the first time in centuries, the primates of churches in many developing regions—including some from Africa, Asia and Latin America—prevailed over the bishops of more prosperous countries (many from the US, Canada and the UK) who had supported a more progressive interpretation of Anglican doctrine. Seen in this light, 1998 is a date that marked the shift from a West-dominated Christianity to one wherein the growing churches of "the two-thirds world" are predominant.

21st-century de facto schisms

Many of the provinces in developed countries have continued to adopt more liberal stances on sexuality and other issues, resulting in a number of de facto schisms, such as the series of splits which led to the creation of the Anglican Church in North America. Many churches are now in full communion with only some other church members of the Communion, but are not with others; however, most churches that have historically been members continue to claim to be part of the Anglican Communion.

On 20 February 2023, following the decision of the Church of England to allow priests to bless same-sex partnerships, during regularly scheduled worship services, ten communion provinces and Anglican realignment churches, formed into the new Global South Fellowship of Anglican Churches, released a statement stating that they had declared "impaired communion" with the Church of England and no longer recognised Justin Welby as "first among equals" among the bishops of the communion.

On 16 October 2025, the chairman of the Global Fellowship of Confessing Anglicans, Laurent Mbanda, declared the future creation of a "Global Anglican Communion" independent from the See of Canterbury but also asserted "[they] have not left the Anglican Communion; [they] are the Anglican Communion." "The statement outlining that plan was signed by one person, Rwanda Archbishop Laurent Mbanda, who serves as chair of GAFCON's primate council." Following the announcement, Mbanda stated that the announcement of the "Global Anglican Communion" was "closer to a rebrand than a new organization" and that they are reforming the existing Anglican Communion. Bishops affiliated with GAFCON, in Kenya and Congo, responded that their provinces plan to remain a part of the existing structures of the Anglican Communion. In December, 2025, Mbanda released another letter restating his plan to remain in the Anglican Communion saying, "We will not walk with sin, but neither will we walk away from the Anglican Communion."

On March 3-4, 2026, meeting in Abuja, GAFCON member churches confirmed their intention to remain a part of the Anglican Communion, rejecting the word "schism" and framing their efforts as a reorganization and "continuity." GAFCON had announced their plan to move forward with electing a "rival" primus inter pares to the Archbishop of Canterbury, with some member churches continuing to oppose the ordination of women as bishops. On March 5, 2026, GAFCON decided not to elect a "rival" primus inter pares to the Archbishop of Canterbury, opting instead to elect a "Global Anglican Council." As of 2025, GAFCON claims to represent upwards of 85% of the world's practising Anglicans. Peer-reviewed research from 2015 and 2016 indicates that the GAFCON-aligned provinces represent closer to 45% of practising Anglicans and just over 54% of members baptised in any of the provinces of the Anglican Communion.

Differences and controversies

Anglican Communion

Some effects of the Anglican Communion's dispersed authority have been differences of opinion (and conflicts) arising over divergent practices and doctrine in the various parts of the communion. Disputes that had been confined to the Church of England could be dealt with legislatively in that realm, but as the communion spread into new countries and territories and across disparate cultures, controversies sometimes multiplied and intensified. These controversies have generally been of two types: liturgical and social.

Ordination of women

Rapid social change and the dissipation of British cultural hegemony over its former colonies contributed to disputes over the role of women, and the parameters of marriage and divorce. In the late 1970s, the Continuing Anglican movement produced a number of new church bodies in opposition to women's ordination, prayer book changes, and the new understandings concerning marriage. As of 2024, some provinces of the communion, representing approximately 3% of Anglicans worldwide, do not ordain women as deacons, priests, or bishops; two ordain women only as deacons, 16 ordain women as deacons and priests but not as bishops, and 22 provinces, representing about "two thirds of Anglicanism," ordain women as deacons, priests, and bishops. As of 2024, three provinces of the Anglican Communion (South East Asia, Papua New Guinea, and Melanesia) do not ordain women as deacons, priests, or bishops. On 28 January 2026, Sarah Mullally, previously bishop of London, was elected as archbishop of Canterbury, becoming the first woman to hold the see and act as the "first among equals" within the Anglican Communion. GAFCON Primates Council chairman (Laurent Mbanda) claimed a predominant reservation against women's ordination to the episcopacy.

Anglo-Catholicism

The first such controversy of note concerned that of the growing influence of the Catholic Revival manifested in the Tractarian and so-called Ritualist controversies of the late 19th and early 20th centuries. This controversy produced the Free Church of England and, in the United States and Canada, the Reformed Episcopal Church.

Abortion and euthanasia

While individual Anglicans and member churches within the communion differ over the circumstances in which abortion should or should not be permitted, Lambeth Conference resolutions have consistently held to a conservative view on the issue. The 1930 conference, the first to be held since the initial legalisation of abortion in Europe (in Russia in 1920), stated:

The Conference further records its abhorrence of the sinful practice of abortion.

The 1958 conference's Family in Contemporary Society report affirmed the following position on abortion and was commended by the 1968 conference:

In the strongest terms Christians reject the practice of induced abortion or infanticide, which involves the killing of a life already conceived (as well as a violation of the personality of the mother), save at the dictate of strict and undeniable medical necessity ... the sacredness of life is, in Christian eyes, an absolute which should not be violated.

The subsequent Lambeth Conference, in 1978, made no change to this position and commended the need for "programmes at diocesan level, involving both men and women ... to emphasise the sacredness of all human life, the moral issues inherent in clinical abortion, and the possible implications of genetic engineering."

In the context of debates around and proposals for the legalisation of euthanasia and assisted suicide, the 1998 conference affirmed that "life is God-given and has intrinsic sanctity, significance and worth".

Same-sex unions and LGBT clergy

More recently, disagreements over homosexuality have strained the unity of the communion as well as its relationships with other Christian denominations, leading to another round of withdrawals from the Anglican Communion. Some churches were founded outside the Anglican Communion in the late 20th and early 21st centuries, largely in opposition to the ordination of openly homosexual bishops and other clergy and are usually referred to as belonging to the Anglican realignment movement, or else as "orthodox" Anglicans. These disagreements were especially noted when The Episcopal Church (US) consecrated an openly gay bishop in a same-sex relationship, Gene Robinson, in 2003, which led some Episcopalians to defect and found the Anglican Church in North America (ACNA); then, the debate reignited when the Church of England agreed to allow clergy to enter into same-sex civil partnerships, as long as they remained celibate, in 2005. The Church of Nigeria opposed the Episcopal Church's decision as well as the Church of England's approval for celibate civil partnerships.

According to the BBC, "The more liberal provinces that are open to changing Church doctrine on marriage in order to allow for same-sex unions include Brazil, Canada, New Zealand, Scotland, South India, South Africa, the US and Wales". In 2023, the Church of England announced that it will authorise "prayers of thanksgiving, dedication and for God's blessing for same-sex couples". The Church of England also permits clergy to enter into same-sex civil partnerships. In 2024, the Church of England's General Synod voted to support allowing clergy to enter in civil same-sex marriages. In 2023, the Anglican Church of Southern Africa's bishops approved the drafting of prayers that could be said with same-sex couples and the draft prayers were published for consideration in 2024. The Church of Ireland has no official position on civil unions, and one senior cleric has entered into a same-sex civil partnership. The Church of Ireland recognised that it will "treat civil partners the same as spouses". The Anglican Church of Australia does not have an official position on homosexuality, and each diocese is allowed to bless same-sex couples if they choose. In 2025, the Church in Wales elected Cherry Vann as the Archbishop of Wales, making her the first woman to serve as Archbishop in the United Kingdom and the first openly LGBTQ and partnered bishop to be a Primate within the Anglican Communion.

The conservative Anglican churches encouraging the realignment movement are more concentrated in the Global South. For example, the Anglican Church of Kenya, the Church of Nigeria and the Church of Uganda have opposed homosexuality. GAFCON, a fellowship of conservative Anglican churches, has appointed "missionary bishops" in response to the disagreements with the perceived liberalisation in the Anglican churches in North America and Europe. In 2023, ten archbishops within the Anglican Communion and two breakaway churches in North America and Brazil from the Global South Fellowship of Anglican Churches (GSFA) declared a state of impaired communion with the Church of England and announced that they would no longer recognise the archbishop of Canterbury as the "first among equals" among the bishops in the Anglican Communion. However, in the same statement, the ten archbishops said that they would not leave the Anglican Communion. In 2024, the GSFA met again establishing "a new structure," no longer recognising the Archbishop of Canterbury "as the de facto leader" of the Anglican Communion, but the GSFA reiterated that they intend to remain in the Anglican Communion. In 2025, after the Church in Wales elected the first openly lesbian and partnered primate in the Anglican Communion, the GSFA criticized the appointment.

Debates about social theology and ethics have occurred at the same time as debates on prayer book revision and the acceptable grounds for achieving full communion with non-Anglican churches.

Ecclesiology, polity and ethos

Anglican Communion

The Anglican Communion has no official legal existence nor any governing structure that might exercise authority over the member churches. There is an Anglican Communion Office in London, under the aegis of the archbishop of Canterbury, but it serves only in a supporting and organisational role. The communion is held together by a shared history, expressed in its ecclesiology, polity and ethos, and also by participation in international consultative bodies.

Three elements have been important in holding the communion together: first, the shared ecclesial structure of the component churches, manifested in an episcopal polity maintained through the apostolic succession of bishops and synodical government; second, the principle of belief expressed in worship, investing importance in approved prayer books and their rubrics; and third, the historical documents and the writings of early Anglican divines that have influenced the ethos of the communion.

Originally, the Church of England was self-contained and relied for its unity and identity on its own history, its traditional legal and episcopal structure, and its status as an established church of the state. As such, Anglicanism was from the outset a movement with an explicitly episcopal polity, a characteristic that has been vital in maintaining the unity of the communion by conveying the episcopate's role in manifesting visible catholicity and ecumenism.

Early in its development following the English Reformation, Anglicanism developed a vernacular prayer book, called the Book of Common Prayer. Unlike other traditions, Anglicanism has never been governed by a magisterium nor by appeal to one founding theologian, nor by an extra-credal summary of doctrine (such as the Westminster Confession of the Presbyterian churches). Instead, Anglicans have typically appealed to the Book of Common Prayer (1662) and its offshoots as a guide to Anglican theology and practise. This has had the effect of inculcating in Anglican identity and confession the principle of lex orandi, lex credendi ("the law of praying [is] the law of believing").

Protracted conflict through the 17th century, with radical Protestants on the one hand and Roman Catholics who recognised the primacy of the Pope on the other, resulted in an association of churches that was both deliberately vague about doctrinal principles, yet bold in developing parameters of acceptable deviation. These parameters were most clearly articulated in the various rubrics of the successive prayer books, as well as the Thirty-nine Articles of Religion (1563). These articles have historically shaped and continue to direct the ethos of the communion, an ethos reinforced by its interpretation and expansion by such influential early theologians such as Richard Hooker, Lancelot Andrewes and John Cosin.

With the expansion of the British Empire and the growth of Anglicanism outside Great Britain and Ireland, the communion sought to establish new vehicles of unity. The first major expressions of this were the Lambeth Conferences of the communion's bishops, first convened in 1867 by Charles Longley, the archbishop of Canterbury. From the beginning, these were not intended to displace the autonomy of the emerging provinces of the communion, but to "discuss matters of practical interest, and pronounce what we deem expedient in resolutions which may serve as safe guides to future action".

Chicago Lambeth Quadrilateral

One of the enduringly influential early resolutions of the conference was the so-called Chicago-Lambeth Quadrilateral of 1888. Its intent was to provide the basis for discussions of reunion with the Roman Catholic and Orthodox churches, but it had the ancillary effect of establishing parameters of Anglican identity. It establishes four principles with these words:

That, in the opinion of this Conference, the following Articles supply a basis on which approach may be by God's blessing made towards Home Reunion: (a) The Holy Scriptures of the Old and New Testaments, as "containing all things necessary to salvation," and as being the rule and ultimate standard of faith. (b) The Apostles' Creed, as the Baptismal Symbol; and the Nicene Creed, as the sufficient statement of the Christian faith. (c) The two Sacraments ordained by Christ Himself – Baptism and the Supper of the Lord – ministered with unfailing use of Christ's Words of Institution, and of the elements ordained by Him. (d) The Historic Episcopate, locally adapted in the methods of its administration to the varying needs of the nations and peoples called of God into the Unity of His Church.

Instruments of communion

The archbishop of Canterbury's role is strictly symbolic and unifying, while the communion's three international bodies are consultative and collaborative; their resolutions have no legal effect on the autonomous provinces of the communion. However, in combination those four bodies do function as "instruments of communion", because all churches of the communion participate in them. In order of antiquity, they are:

The Chair of St Augustine (the episcopal throne in Canterbury Cathedral, Kent), seat of the archbishop of Canterbury in their role as head of the Anglican Communion

• The archbishop of Canterbury functions as the spiritual head of the communion. The archbishop is the focus of unity, because no Anglican church has historically claimed membership in the communion without being in communion with the archbishop of Canterbury. The current archbishop-designate is Sarah Mullally. • The Lambeth Conference (first held in 1867) is the oldest Anglican international consultative body. It is a forum for bishops of the communion to reinforce unity and collegiality, to discuss matters of mutual concern, and to pass resolutions intended to act as guidelines to the individual churches. It is held roughly every ten years and invitation is by the archbishop of Canterbury. • The Anglican Consultative Council (first met in 1971) was created by a 1968 Lambeth Conference resolution, and meets usually at three-yearly intervals. The council consists of representative bishops, other clergy and laity chosen by the 38 provinces. The body has a permanent secretariat, the Anglican Communion Office, of which the archbishop of Canterbury is president. • The Primates' Meeting (first met in 1979) is a forum for international consultation and deliberation, first convened by Archbishop Donald Coggan for "leisurely thought, prayer and deep consultation".

Because there is no binding authority in the Anglican Communion, these international bodies are vehicles for consultation and persuasion. In the late twentieth and early twenty-first centuries, they have debated issues of conformity in doctrine, discipline, worship and ethics. The most controversial issues have related to gender and sexuality: some provinces of the communion (particularly in Africa and Asia) object to the changing acceptance of LGBTQ+ individuals (particularly by the North American and European churches). This has led to disagreements on the churches' differing practices of blessing same-sex unions, ordaining and consecrating priests and bishops who are (or have been) in same-sex relationships, and to the process by which changes were undertaken. Some churches have also objected to the ordination of female priests and bishops. This debate is known as the Anglican realignment.

Those who objected condemned these changes as unscriptural, unilateral, and lacking prior agreement from the communion. The American Episcopal Church and the Anglican Church of Canada responded that their actions had been undertaken after lengthy scriptural and theological reflection, were legal according to their own canons and constitutions, and made after extensive consultation with the provinces of the communion. The Primates' Meeting voted to request those two churches withdraw their delegates from the 2005 meeting of the Anglican Consultative Council. Canada and the United States decided to attend the meeting but without exercising their right to vote. They were not expelled or suspended; there is no mechanism in this voluntary association to suspend or expel an independent province of the communion. Because membership is based on a province's communion with Canterbury, expulsion would require the archbishop of Canterbury's refusal to be in communion with the affected jurisdictions. Following the recommendation of the Windsor Report, Rowan Williams (the then archbishop of Canterbury) established a working group to examine the feasibility of an Anglican covenant which would articulate the conditions for communion in some fashion.

Nairobi-Cairo proposals

In 2025, the Inter-Anglican Standing Committee on Unity, Faith and Order within the Anglican Communion proposed a series of changes to the Instruments of Communion that would result "in service of a de-centred, polycentric understanding of the mission of the Church. . . The leadership of the Communion should look like the Communion," according to the report. The Nairobi-Cairo proposals suggests amending the definition of membership in the Anglican Communion to no longer include reference to being in full communion with the Archbishop of Canterbury; instead, the reference to Canterbury would be a historical connection. Additionally, there would be a rotating presidency of the Anglican Consultative Council among the five regions of the communion, and the role of calling the Lambeth Conference and Primates' Meeting, traditionally held by the Archbishop of Canterbury, would include greater input from the Primates' Standing Committee. This has both been described as an effort to further decolonize the structures of the Anglican Communion as well as an effort to hold together autonomous member churches with disagreements.

Organisation

Provinces

A world map showing the provinces of the Anglican Communion and Global Anglican Communion: The Church of Ireland serves both Northern Ireland and the Republic of Ireland and the Anglican Church of Korea serves South Korea and, theoretically, North Korea. Indian Anglicanism is divided into the Church of North India, and the Church of South India. The Diocese in Europe (formally the Diocese of Gibraltar in Europe), in the Province of Canterbury, is also present in Portugal and Spain. The Episcopal Church, USA-affiliated Convocation of Episcopal Churches in Europe has affiliates in Austria, Belgium, France, Georgia, Germany and Italy.

The Anglican Communion, which currently is experiencing impaired communion and division, consists of forty-two autonomous provinces each with its own primate and governing structure and of five extra-provincials under the metropolitan authority of the Archbishop of Canterbury. These provinces may take the form of national churches (such as in Canada, Uganda, or Japan) or a collection of nations (such as the West Indies, Central Africa, or Southeast Asia). The Church of England Yearbook reported 93,511,730 members of the Anglican Communion in 2024.

Excluding the United churches in South Asia, the World Christian Database, published in 2021 and produced by the Center for the Study of Global Christianity at Gordon-Conwell Theological Seminary, and the World Christian Encyclopedia, published in 2020 by Edinburgh University Press, estimated that there were approximately 97,399,000 Anglicans in 2020 with 63,556,000 in Africa, 24,400,000 in Europe, 4,565,000 in Oceania, 2,689,000 in Northern America, 1,230,000 in Asia, and 959,000 in Latin America. The United Churches in South Asia include over 5,000,000 in South India, 2,300,000 in North India, 1,900,000 in Pakistan, and 22,600 in Bangladesh.

The ten largest member churches of the Anglican Communion, as measured by total reported membership, not by active membership, are reportedly the churches based in England, Nigeria, Uganda, Kenya, Australia, South India, Southern Africa, South Sudan, Tanzania, and the Episcopal Church.

Extraprovincial churches

In addition to the forty-two provinces, there are five extraprovincial churches under the metropolitical authority of the archbishop of Canterbury.

New provinces in formation

In September 2020, the archbishop of Canterbury announced that he had asked the bishops of the Church of Ceylon to begin planning for the formation of an autonomous province of Ceylon, so as to end his current position as metropolitan of the two dioceses in that country.

In 2023, the Church of the Province of Central Africa approved a plan to subdivide into three new national provinces, so that churches in Malawi, Zambia, and Zimbabwe would become independent of each other, while churches in Botswana could form a fourth national province or be integrated into one of the other three national provinces being formed.

In relation to the Church of the Province of West Africa, it was announced that "the process is in motion for Ghana to become an autonomous province, once it has fulfilled the conditions and guidelines set by the Anglican Communion."

Churches in full communion

In addition to other member churches, the churches of the Anglican Communion are in full communion with the Old Catholic churches of the Union of Utrecht and the Scandinavian Lutheran churches of the Porvoo Communion in Europe, the India-based Malankara Mar Thoma Syrian and Malabar Independent Syrian churches and the Philippine Independent Church, also known as the Aglipayan Church.

Historic episcopate

Anglican Communion

The churches of the Anglican Communion have traditionally held that ordination in the historic episcopate is a core element in the validity of clerical ordinations. The Roman Catholic Church, however, does not recognise Anglican orders (see Apostolicae curae). Some Eastern Orthodox churches have issued statements to the effect that Anglican orders could be accepted, yet have reordained former Anglican clergy; other Eastern Orthodox churches have rejected Anglican orders altogether. In 1922, the Ecumenical Patriarch of Constantinople, Meletius IV, issued a statement recognising that Anglican Holy Orders, through apostolic succession, possess the same validity as those of the Roman, Old Catholic, and Armenian Churches. By 1946, five autocephalous Orthodox jurisdictions recognised the validity of Anglican Holy Orders, including Constantinople, Alexandria, Jerusalem, Cyprus, and Romania. This recognition, however, was conditional because from an Eastern Orthodox standpoint, no Holy Orders outside of their church could truly be valid without a complete church reunion. The Church of Greece also recognised the validity of Anglican Orders in 1939, albeit "by economy" or "as an indulgence;" these recognitions have "not been rescinded." However, in 1948, the Russian Orthodox Church responded that it would not recognise Anglican Orders unless recognition was given by a council of autocephalous Orthodox churches. Orthodox bishop Kallistos Ware explains this apparent discrepancy as follows:

Anglican clergy who join the Orthodox Church are reordained; but [some Orthodox churches hold that] if Anglicanism and Orthodoxy were to reach full unity in the faith, perhaps such reordination might not be found necessary. It should be added, however, that a number of individual Orthodox theologians hold that under no circumstances would it be possible to recognise the validity of Anglican Orders.
