The Thirty-Nine Articles of Religion were established in 1563 and are the historic defining statements of Anglican doctrine in relation to the controversies of the English Reformation; especially in the relation of Calvinist doctrine and Roman Catholic practices to the nascent Anglican doctrine of the evolving English Church. The name is commonly abbreviated as the Thirty-Nine Articles or the XXXIX Articles. The Church of England was searching out its doctrinal position in relation to the Roman Catholic Church and the continental Protestants. A series of defining documents were written and replaced over a period of 30 years as the doctrinal and political situation changed from the excommunication of Henry VIII in 1533, to the excommunication of Elizabeth I in 1570.
