The word “Anglican” simply means “of or relating to England or the English.” So an Anglican church is either a church within the Church of England or a church whose roots are connected to the Church of England.
The Anglican Communion is the worldwide fellowship of churches owing their origins to the Church of England; it is the third largest church in the world. It is a fellowship within the one, holy, catholic, and apostolic church.
Anglicans and Episcopalians the world over share aspects of their history, tradition and ways of worshipping, but no two churches are exactly alike. This unity in diversity is one of the things that make the Anglican Communion so special.
