Three Forms of Unity

Written by Guido de Bres in 1561 at the cost of his life, the Belgic Confession sets forth the Reformed faith in 37 articles - from the doctrine of God to the last judgment. It was cast over a castle wall to the persecutors of the church as a testimony that the Reformed believe nothing contrary to Holy Scripture.

Composed in 1563 by Zacharias Ursinus and Caspar Olevianus, the Heidelberg Catechism unfolds the Christian faith through 52 Lord's Days of questions and answers. Its opening question - 'What is thy only comfort in life and death?' - has been the comfort of God's people for over four centuries.

Adopted at the great Synod of Dort (1618–19), the Canons defend the five points of Calvinism against the errors of the Arminians: total depravity, unconditional election, limited atonement, irresistible grace, and the perseverance of the saints - the doctrines of sovereign, particular grace.
