The Anglican Communion is an international association of churches consisting of the Church of England and of national and regional Anglican churches in full communion with it. The status of full communion means, ideally, that there is mutual agreement on essential doctrines and that full participation in the sacramental life of each church is available to all communicant Anglicans.
The Archbishop of Canterbury has a precedence of honour over the other archbishops of the Anglican Communion. He is recognized as primus inter pares, or first among equals. The archbishop does not exercise direct authority in the provinces outside England, but instead acts as a focus of unity.
The Anglican Communion considers itself to be part of the One, Holy, Catholic and Apostolic Church and to be both Catholic and Reformed. For some adherents it represents a non-papal Catholicism, for others a form of Protestantism though without a dominant guiding figure such as Luther, Knox, Calvin, Zwingli or Wesley. For others, their self-identity represents some combination of the two. The communion encompasses a wide spectrum of belief and practice including evangelical, liberal, and Catholic.
With a membership currently estimated at around 80 million members worldwide, the Anglican Communion is the third largest Christian communion in the world, after the Roman Catholic Church and the Eastern Orthodox Church. Some of these churches are known as Anglican, such as the Anglican Church of Canada, due to their historical link to England (Ecclesia Anglicana means “English Church”). Some, for example the Church of Ireland, the Scottish and American Episcopal churches, and some other associated churches have a separate name. Each church has its own doctrine and liturgy, based in most cases on that of the Church of England.

In the sixth century the Catholic Church arrived in England through missionaries from Rome and Ireland. This church grew and spread and was an integral part of the wider Catholic communion. In the sixteenth century the church in England declared itself independent from Rome under Henry VIII and then in 1570 Pope Pius V excommunicated Queen Elizabeth I. The church in England then became “The Church of England” and later was referred to simply as the “Anglican Church” (from the word “Anglo”). Anglicans settled in many countries throughout the world and were among the first to settle in North America shortly after the Puritans arrived. However, when the Revolutionary War occurred in North America, the U.S. declared its independence from England and American Anglicans quickly changed their name to “Episcopalians” in order to avoid persecution and obvious ties to England. “Episcopal” simply means “to have bishops.” Today the Anglican Communion consists of churches on every continent. In order to be a member of the Anglican Communion, a Church must be in communion with the Archbishop of Canterbury in Canterbury, England. There are currently many Anglicans in countries where the British established colonies and focused missionary efforts including Africa (particularly the Sudan and Nigeria), India, and China, but Anglicans can be found in every country today. Anglicanism is the third largest Christian religious body in the world.
Anglicanism was heavily influenced by the Protestant Reformation and this accounts for some significant differences. An Anglican worship service or “mass” is almost identical to a Roman Catholic service except for a few minor differences. The most obvious difference is the fact that most Episcopalians ordain women to the Diaconate, Episcopate, and Priesthood, unlike the Roman Catholic Church. But many other differences exist between Roman Catholics and Anglicans as well. For example, all Anglicans allow their clergy to marry and celibacy is never mandated for clergy unless they are under Religious vows as a monk or nun. Many Episcopal Dioceses ordain homosexuals and bless homosexual unions. While Anglicans respect the Papacy, they are not under Papal authority. Anglicans allow for family planning among their members and encourage the use of contraceptives. Divorce and remarriage is also allowed in the Episcopal Church with the counsel and consent of one’s priest and Bishop.
