A national Synod was called to meet in Dort in 1618 for the purpose of examining the views of Arminius in the light of Scripture. The Great Synod was convened by the States-General of Holland on November 13, 1618. There were 84 members and 18 secular commissioners. Included were 27 delegates from Germany, the Palatinate, Switzerland and England. There were 154 sessions held during the seven months that the Synod met to consider these matters, the last of which was on May 9, 1619. — David N. Steele
The Synod rejected Arminianism. As do all wise souls. Since it’s just semi-Pelagianism with a new name.
