Canons of Dort
The Canons of Dort were produced by the Synod of Dort (1618–1619), an international Reformed council convened to adjudicate the controversy raised by Jacobus Arminius and his followers (the Remonstrants). The Remonstrants submitted five articles in 1610 asserting conditional election, universal atonement, resistible grace, and the possibility of falling from grace. The Synod replied with five "heads of doctrine" — the Calvinist doctrines popularly summarized as TULIP. Together with the Heidelberg Catechism and the Belgic Confession, the Canons form the Three Forms of Unity.
For he chose us in him before the creation of the world to be holy and blameless in his sight. In love he predestined us for adoption to sonship through Jesus Christ, in accordance with his pleasure and will. — Ephesians 1:4–5
