An ecclesiastic of Friesland, embraced the tenets of the Anabaptists, and, after being again baptized by Ubbo Philippi, became a powerful leader of his sect. He denied that Jesus Christ received a human shape from his mother, the virgin Mary; and while he maintained the necessity of again baptizing adults, he inveighed against the custom of infant baptism, which he regarded as Popish innovation. His eloquence and his learning were so much admired, that he gained a great number of followers in Westphalia, Guelderland, Holland, and Brabant; but, though a price was set on his head, he had the good fortune to escape his persecutors. He was, in his opinions, more moderate than the rest of the Anabaptists. His followers are still to be found in the Low Countries, under the name of Mennonites, divided into two distinct sects. He died at Oldeslo, between Lubec and Hamburg, 1565. His works were published at Amsterdam, 1681.
