The Anglican Communion is a confederation of national churches, each considered independent, yet sharing Full Communion with one another and the Archbishop of Canterbury, who is the spiritual (although not administrative) head of the Communion. The Anglican Communion maintains the traditional three-fold hierarchy of clergy: Bishops, Priests and Deacons. In some member churches, women have been admitted to one or more of these orders, whereas some member churches have maintained an all-male clergy. Beyond the three-fold order, though the administration and leadership of each national church is decided by that particular church. In the Church of England, for example, the Queen appoints Bishops. In the Episcopal Church (USA), on the other hand, bishops are elected by diocese and then confirmed by the House of Bishops.
