The canon law of the Church of England identifies the Christian scriptures as the source of its doctrine. In addition, doctrine is also derived from the teachings of the Church Fathers and ecumenical councils (as well as the ecumenical creeds) in so far as these agree with scripture. This doctrine is expressed in the Thirty-Nine Articles of Religion, the Book of Common Prayer, and the Ordinal containing the rites for the ordination of deacons, priests, and the consecration of bishops. Unlike other traditions, the Church of England has no single theologian that it can look to as a founder. However, Richard Hooker's appeal to scripture, church tradition, and reason as sources of authority continue to inform Anglican identity.
