The Thirty-Nine Articles are the defining statements of Anglican doctrine. They were issued by the Convocation of clergy of the Church of England in 1571 and are printed in the Book of Common Prayer and other Anglican prayer books. The Test Act of 1673 made adherence to the Thirty-Nine Articles a requirement for holding civil office in England.
The Articles highlight some of the major differences between Anglican and Catholic doctrine, including:
The Articles also argue against some Anabaptist positions such as the holding of goods in common, and the necessity of believer's baptism.
"Tract 90" was John Henry Newman's response to the Thirty-Nine Articles, written before his conversion to Roman Catholicism.
The Articles were not intended as a complete statement of the Christian faith, but as a statement of the position of the Church of England over against the Roman Catholic Church and some continental Reformers.
