Few men in Germany, or outside it, were more fitted to hold their own in such a disputation than the distinguished Vice-Chancellor of Ingolstadt. He was a man of imposing appearance, gifted with a clear and pleasing voice and good memory, even tempered and ready, quick to detect the weak points of his adversaries, and keenly alert to their damaging concessions and admissions. The first point to be debated between him and Carlstadt was the question of Grace and Free Will. Carlstadt was at last obliged to concede that the human will was active at least to the extent of co-operating or of not co-operating with divine Grace, a concession that was opposed entirely to the thesis he had undertaken to sustain. Luther, alarmed by the discomfiture of his colleague, determined to enter the lists at once on the question of the primacy of the Roman See. He was not, however, more successful than Carlstadt. Eck, taking advantage of Luther's irascible temperament and his exaggerations of speech, forced him step by step to put aside as worthless interpretations given by the early Fathers to certain passages of Scripture, and to reject the authority and infallibility of General Councils. Such a line of arguments, opposed as it was to the teaching and beliefs of the Church, roused the opposition of the audience, and served to open the eyes of Duke George to the real nature of Luther's movement. Annoyed by his own defeat and by the attentions and applause lavished upon his rival by the people of Leipzig, Luther left the city in disgust. The disputation undoubtedly did good in so far as it made clear to all the position of the two parties, and succeeded in holding Duke George of Saxony and the city of Leipzig loyal to the Church; but it also did much harm by giving Luther the notoriety that he was so anxious to obtain, and by winning to his side Philip Melanchthon, who was destined to be in after life his ablest lieutenant. Both sides, as is usual in such contests, claimed the victory. The Universities of Cologne and Louvain condemned Luther immediately, as did also Paris in 1521, but as far as can be known Erfurt pronounced no decision on the questions submitted.
