The Thirty-Nine Articles of Religion, finalized in 1571, serve as the doctrinal foundation of the Church of England and the Anglican Communion, shaping its position during the English Reformation. Developed from earlier texts such as the Ten Articles (1536) and the Forty-two Articles (1552), they struck a balance between Catholic customs and Protestant changes, affirming essential beliefs including justification by faith, the sacraments, and the supremacy of Scripture.
Included in the Book of Common Prayer, they established a uniform Anglican theology, affecting worship practices and church leadership. Their influence continues in the present-day conversation between tradition and renewal within Anglicanism.
