He was strongly impressed with the fundamental contradictions which he believed to exist between the new evangelical doctrines preached by Luther and the theories and practices of the mediæval religious life and worship. This led him to attack earnestly and bitterly monastic vows, celibacy, a distinctive dress for the clergy, the idea of a propitiatory sacrifice in the Mass, and the presence and use of images and pictures in the churches. He introduced all these questions of practical interest into the University weekly Public Discussions; he published theses upon them; he printed two books—one on monastic vows and the other on the Mass—which had an extensive circulation both in German and in Latin (four editions were speedily exhausted). The prevailing idea in all these publications, perhaps implied rather than expressed, was that the new evangelical liberty could only be exercised when everything which suggested the ceremonies and usages of the mediæval religious life was swept away. His strongest denunciations were reserved for the practice of celibacy; he dwelt on the divine institution of marriage, its moral and spiritual necessity, and taught that the compulsory marriage of the clergy was better than the enforced celibacy of the mediæval Church. Zwilling, a young Augustinian Eremite, whose preaching gifts had been praised by Luther, went even further than Carlstadt in his fiery denunciation of the Mass as an idolatrous practice. The movement to put these exhortations in practice began first among the clergy. Two priests in parishes near Wittenberg married; several monks left their cloisters and donned lay garments; Melanchthon and several of his students, in semi-public fashion, communicated in both kinds in the parish church on Michaelmas Day (Sept. 29th), 1521, and his example seems to have been followed by other companies. Zwilling’s fiery denunciations of the idolatry of the Mass stirred the commonalty of the town. On Christmas Eve (Dec. 24-25), 1521, a turbulent crowd invaded the parish church and the Church of All Saints. In the former they broke the lamps, threatened the priests, and in mockery of the worship of praise they sang folk-songs, one of which began: “There was a maid who lost a shoe”—so the indignant clergy complained to the Elector.(310) Next day, Christmas, Carlstadt, who was archdeacon, conducted the service in All Saints’ Church. He had doffed his clerical robes, and wore the ordinary dress of a layman. He preached and then dispensed the Lord’s Supper in an “evangelical fashion.” He read the usual service, but omitted everything which taught a propitiatory sacrifice; he did not elevate the Host; and he placed the Bread in the hands of every communicant, and gave the Cup into their hands. On the following Sundays and festival days the Sacrament of the Supper was dispensed in the same manner, and we are told that “hic pæne urbs et cuncta civitas communicavit sub utraque specie.”
