While the controversy was pending, Dr. Eck, of the university of Ingolstadt, a man of great scholastic ingenuity and attainment, and proud of the prizes of eight universities, challenged the professors of Wittemberg to a public controversy on Grace and Free Will. He regarded a disputation with the eye of a practised fencer, and sought the means of extending his fame over North Germany. Leipsic was the appointed arena, and thither resorted the noble and the learned of Saxony. Eck was among the first who arrived, and, soon after, came Carlstadt, Luther, and Melancthon.

The place for the combat was a hall in the royal palace of Duke George, cousin to the elector Frederic, which was arranged and ornamented with great care, and which was honored by the presence of the duke, and of the chief divines and nobles of Northern Germany. Carlstadt opened the debate, which did not excite much interest until Luther's turn came, the antagonist whom Eck was most desirous to meet, and whose rising fame he hoped to crush by a brilliant victory. Ranke thus describes Luther's person at this time. "He was of the middle size, and so thin as to be mere skin and bone. He possessed neither the thundering voice, nor the ready memory, nor the skill and dexterity, of his distinguished antagonist. But he stood in the prime of manhood and in the fulness of his strength. His voice was melodious and clear; he was perfectly versed in the Bible, and its aptest sentences presented themselves unbidden to his mind; above all, he inspired an irresistible conviction that he sought the truth. He was always cheerful at home, and a joyous, jocose companion at table; he even, on this grave occasion, ascended the platform with a nosegay in his hand; but, when there, he displayed the intrepid and self-forgetting earnestness arising from the depth of a conviction, until now, unfathomed, even by himself. He drew forth new thoughts, and placed them in the fire of the battle, with a determination that knew no fear and no personal regard. His features bore the traces of the storms that had passed over his soul, and of the courage with which he was prepared to encounter those which yet awaited him. His whole aspect evinced profound thought, joyousness of temper, and confidence in the future. The battle immediately commenced on the question of the authority of the papacy, which, at once intelligible and important, riveted universal attention." Eck, with great erudition and masterly logic, supported the claim of the pope, from the decrees of councils, the opinions of scholastics, and even from those celebrated words of Christ to Peter--"Thou art Peter, and on this rock will I build my church," &c. Luther took higher and bolder ground, denied the infallibility of councils, and appealed to Scripture as the ultimate authority. Eck had probably the advantage over his antagonist, so far as dialectics were concerned, being a more able disputant; but Luther set at defiance mere scholastic logic, and appealed to an authority which dialectics could not reach. The victory was claimed by both parties; but the result was, that Luther no longer acknowledged the authority of the Roman church, and acknowledged none but the Scriptures.
