The Books of Homilies are two books together containing thirty-three sermons developing the authorized reformed doctrines of the Church of England in depth and detail, as appointed for use in the 35th Article of the Thirty-Nine Articles of Religion. The longer title of the collection is Certain Sermons or Homilies Appointed to Be Read in Churches. They belong to the basic formularies of the Church of England.

The Thirty-nine Articles of Religion, finalised in 1571, are the historically defining statements of doctrines and practices of the Church of England with respect to the controversies of the English Reformation. The Thirty-nine Articles form part of the Book of Common Prayer used by the Church of England and the worldwide Anglican Communion, as well as by denominations outside of the Anglican Communion that identify with the Anglican tradition.
