An Anabaptist leader, horn cither at (xhent or Bruges. He was apprenticed to a glass-painter, and soon displayed great aptitude in the work. To perfect himself in the art. he visited Belgium, France, and England. Returning to Holland, he settled at Delft, practicing his trade (1524) ; but in 1528 he began to display unusual religious zeal against Roman Cathol- icism, and, while a procession on Ascension Day was passing in Delft, he stopped the priests, accused them of deceiving the people by false teachings, and reproached them for wor- shiping images and pictures. He was arrested and banished for three years. Abandoning the common principles of the Reformation, he became an adherent of Aniibaptist views. At first he did not identify himself with the sect, on account of their disorderly conduct and their doctrine of i:sing the sword to establish their authority; but in 1534 he fully joined them by rebaptism. He was consecrated as Bishop of Delft by Dammas, Ubbo, and others. His inlluence was very great and his followers numerous. The Anabaptist leaders, jealous of his success, openly disavowed him. IJut at the convocation of Anabaptists in 1536 .Joris fearlessly declared himself a divinely appointed leader, and soon afterwards issued a pamphlet calling all parties to a peaceful union. The leaders were still more provoked; and most of the Anabaptists forsook him. Those who adhered to him took the name of .lorists or l);ividists. He profes.sed to have visions and revelations, and in- terpreted the persecutions to which his followers were subjected as proofs of the divine favor. At Delft, Haarlem, Amsterdam, Rotterdam, Leyden, and other cities, many sutlered death for their adhereiice to him. His own mother died on the scall'old, a martyr to the doctrines which her son was propagating (February, 153H). He kept up his wandering life till 1544, when, the voluntary gifts of his followers rendering him independent, he altered his life com|ilctely. In Basid in August of that year appeared a man by the name of John of Bruges. He was wealthy, a eomnnini- cant in the Reformed Church, and had come there with his family. He was highly esteemed for his wealth and his virtues, and died peace- fully, August 2.5, 1550. This was David Joris. For three years his secret was kept. Then his son- in-law. Nicholas Blesdyk, a reformed preacher, but an avaricious and un|)rincipled man, who had been his disciple, revealed the identity of John of Bruges with David Joris. The clergj' and uni- versity declared his opinions heretical, and his body was dug up and burned. The sect, which .loris had secretly communicated with while living in Basel, survived his death half a cen- tury, and circulated his writings, .loris was a thorough mystic, and believed that he had divine visions. He rejected the doctrine of the Trinity, and held strange views concerning Christ. He be- lieved that he was to establish internally and ex- ternally the eternal kingdom of Christ, which before was the kingdom of Christ only internally. He denied the doctrine of future judgment and the existence of angels. He held that the body only was defiled by sin. Of his 250 books and 1000 letters, the most important is the Book of Miraelcs. under the title of ^yonderboeek. In it he adopts the idea of .loiichim of Floris (q.v. ), of three dis])cnsations.
