Anglicanism is one of the traditions, or expressions, of this Christian faith. Other Christian traditions include Roman Catholic, Eastern Orthodox, Oriental Orthodox and Protestant Churches, which include Lutheran, Baptist, and Pentecostal Churches. The word Anglican originates in ecclesia anglicana, a medieval Latin phrase dating to at least 1246 that means the English Church, but in the past two centuries the tradition has been adopted around the world. There are tens of millions of people around the world who are part of national or regional Churches which call themselves Anglican (or Episcopal in some countries). These Churches are collectively are known as the Anglican Communion.
Anglicans and Episcopalians the world over share aspects of their history, tradition and ways of worshipping. But no two churches are exactly alike even within a diocese, let alone a province or between countries. This unity in diversity is one of the things that make the Anglican Communion so special and such rich ground from which to change to world.
