Anglicanism

Anglicanism consists of the Church of England and churches which are historically tied to it or hold similar beliefs, worship practices and church structures. The word Anglican originates in ecclesia anglicana, a medieval Latin phrase dating to at least 1246 that means the English Church. There is no single "Anglican Church" with universal juridical authority, since each national or regional church has full autonomy. As the name suggests, the communion is an association of churches in full communion with the archbishop of Canterbury. The great majority of Anglicans are members of churches which are part of the international Anglican Communion, which has 85 million adherents.

The Church of England declared its independence from the Catholic Church at the time of the Elizabethan Religious Settlement. Many of the new Anglican formularies of the mid-16th century corresponded closely to those of contemporary Reformed tradition. These reforms were understood by one of those most responsible for them, the then archbishop of Canterbury, Thomas Cranmer, as navigating a middle way between two of the emerging Protestant traditions, namely Lutheranism and Calvinism. By the end of the century, the retention in Anglicanism of many traditional liturgical forms and of the episcopate was already seen as unacceptable by those promoting the most developed Protestant principles.

Unique to Anglicanism is the Book of Common Prayer, the collection of services that worshippers in most Anglican churches used for centuries. While it has since undergone many revisions and Anglican churches in different countries have developed other service books, the Book of Common Prayer is still acknowledged as one of the ties that bind the Anglican Communion together.
