An Anglican church, at the level most people encounter it, is a local congregation — a parish — that belongs to a wider diocese and province within the Anglican Communion. What makes a congregation specifically “Anglican” is less about a single building or a single local decision, and more about its place within this wider structure: it is led by clergy ordained within the historic threefold ministry, uses recognisably Anglican patterns of worship, and is accountable to a bishop and diocese.
An Anglican church typically centres its worship on the Holy Eucharist and follows a liturgy drawn from the Book of Common Prayer or a province's own equivalent, moving through the church calendar and a shared lectionary of Bible readings across the year.
Beyond the local parish, “the Anglican Church” can also refer more broadly to any of the independent national or regional churches that make up the Communion — such as the Church of England, the Episcopal Church in the United States, or the Church of Nigeria — each self-governing, but sharing recognisable worship, doctrine, and ministry with the others.
