At Wittenberg there was great excitement, particularly on account of the mass. In the Augustinian convent there, the majority of the monks held with Zwilling; they wished to celebrate the sacrament of the Lord's Supper in strict accordance with the institution of Christ. Their prior, Conrad Held, took the opposite side, and adhered to the ancient usage. Justus Jonas, the provost, expressed his views with equal ardour in the convent church attached to the university, and met with violent opposition from other members of the foundation. A committee, composed of deputies from the university and chapter of canons, from whom the Elector in October demanded a formal opinion on the subject, expressed by their majority the same view, and requested the Elector himself to abolish the abuse of the mass. But Frederick utterly rejected the idea of decreeing on his own authority innovations which would constitute a deviation from the great Christian Catholic Church, more especially as opinions were not agreed on them even at Wittenberg. He would do no more than give free scope and protection to the new testimony of biblical truth, until it should be properly sifted by the Church. In the church of the Augustinian convent, the mass and the Lord's Supper were now both suspended. Men set to work now in earnest to give effect to the new principles applied to monachism. Thirteen Augustine monks, about a third of the then inmates of the convent at Wittenberg, quitted that convent early in November, and cast away their cowls. Some of them took up at once a civil trade or handicraft. This step increased the growing feeling of hostility to the monks among the students and inhabitants of the town. All kinds of enormities ensued: monks were mocked at in the streets; the convents were threatened; and even the service of the mass was disturbed by rioters who forced their way into the parish church. Meanwhile Luther went on, in the quietness of his seclusion, to teach the Christian truth about vows and masses, to explain and establish his newly-acquired knowledge and convictions, and to prepare by that means the way of ultimate reform. He composed a tract, in Latin and German, 'On the Abuse of Masses,' and another, in Latin, 'On Monastic Vows.' The latter he dedicated to his father, taking note of his protest against his entering the convent, and telling him with joy that he was now a free man, a monk, and yet no longer a monk. As for his brethren's desertion of the convent, however, he disapproved the manner of it. They could, and should, have parted in peace and amity, not as they did, in a tumult. These two works he completed in November, and sent them to Spalatin, to have them printed at Wittenberg.
