Cornarists the disciples of Theodore Cornhert or Koornhert, secretary of the States of Holland (t 1590). He wrote against the Romanists, the Lutherans, and Calvinists. He maintained that every religious communion needed reformation, but he said no one had a right to engage in it without a mission supported by miracles. He was also of opinion that connection with the visible Church of Christ was not essential to experimental Christianity. Arminius was directed to refute the writings of Coornbert against predestination, and in studying the subject was led to abandon that doctrine. The complete works of Coornhert were collected at Amsterdam in 1630 (3 vols. fol.). See Mosheim, Church History, 3:400; Bayle, Dictionary, s.v. Koornhart, and the article ARMINIANISM SEE ARMINIANISM .
