The Anglican Communion distinguishes between full communion and intercommunion. The Anglican Communion is the third largest Christian communion of churches. It does not celebrate the rites of Baptism and Holy Communion. Central to the Christian liturgy is the celebration of the Eucharist or "Holy Communion". Bishops started to impart confirmation only after the first Eucharistic communion. Prayer cards often depict the sanctified pontiff with instruments of Holy Communion. He is venerated as a saint in the Catholic Church and the Anglican Communion. The Church of England is also the mother church of the international Anglican Communion. All churches require fasting before one receives Holy Communion. They discussed denominational differences as the ground for restoring church communion. It is also the "mother church" of the worldwide Anglican Communion. As a noun, an Anglican is a member of a church in the Anglican Communion. Some religious orders are unique to the Anglican Communion. Not all member churches of the Anglican Communion have archdeacons. It is also one of four united churches in the Anglican Communion.
