Belgic Confession

Written by Guido de Brès in 1561 as a systematic explanation of the major doctrines which we believe and confess as Reformed Christians in the hope of convincing the Roman Catholic King Philip II to stop persecuting the Dutch Protestants.

Heidelberg Catechism

Written by Zacharias Ursinus and Caspar Olevianus in 1563 in the German city of Heidelberg as a manual for instructing the youth in the truth of God’s Word concerning our sins, our deliverance, and our life of thankfulness, with extensive explanations of the Apostles’ Creed, the Sacraments, the Ten Commandments, and the Lord’s Prayer.

Canons of Dordt

Written by the Synod of Dordt in the Dutch city of Dordrecht in 1618-1619 to refute the heresy of Arminianism and explain the true Reformed doctrines of total depravity, unconditional election, limited atonement, irresistible grace, and the preservation of the saints. These five canons came to be known as the Five Points of Calvinism (TULIP).
