In "The Remonstrance" and some later writing, the Arminians wrote about an alternative to the Calvinist Belgic Confession and mentioned several things that they disagreed with. They taught election on the basis of God knowing who would have faith, a universal atonement, resistible grace and the possibility of walking away from grace. Simon Episopius was the speaker for the 13 members of the Remonstrants who were called to the Synod in 1618.
