ecclesiastical reformer. He became cathedral preacher at Worms in 1463. Charged with preaching Hussite doctrines on the Church and sacraments, he was deposed from his office in 1447 and in 1479 tried before the Inquisition. After recanting he was imprisoned for life. His writings include a ‘Commentary on the Sentences’, a treatise against indulgences, and a work on the Immaculate Conception. He held that Scripture alone was the final authority in faith.
