Heidelberg Catechism
52 Lord's Days · 1563
Written in 1563, the Heidelberg Catechism unfolds the Christian faith through 52 Lord's Days of questions and answers, organized into three parts: man's misery, God's deliverance in Christ, and grateful obedience.
Belgic Confession
37 Articles · 1561
Written in 1561 by Guido de Bres, the Belgic Confession presents the Reformed faith in 37 articles covering God, Scripture, creation, salvation, the church, and the last things.
Canons of Dort
5 Heads of Doctrine · 1618–1619
Adopted at the Synod of Dort (1618–1619), the Canons defend the five points of Calvinist soteriology—total depravity, unconditional election, limited atonement, irresistible grace, and perseverance of the saints.
