During the negotiations in the presence of Cajetan at Augsburg we can see even more clearly how Luther stood under the spell of his idea, that the only Church was a spiritual one, and that, even should he break away from ecclesiastical authority by rising against the Ban, he would still remain in this Church. It was after his return from Augsburg, during the stormy days when he appealed “from the Pope to a General Christian Council,” i.e. in the winter of 1518, that he discovered the true “Antichrist” who reigned at Rome.[1121] This discovery deprived him of the last vestige of respect for the authority of the Church and for her head.[1122] His own inward state when he made this discovery was one of curious turmoil. In his letter to Link, of Dec. 11, 1518, we hear him speaking of his commotion of mind, of new projects just on the point of birth which would show that, so far, he had hardly made a serious beginning with the struggle; he had a “premonition” then that Antichrist described by St. Paul (2 Thes. ii. 3 ff.) was seated in Rome where he behaved even worse than the Turk.[1123] At the beginning of 1519 with bated breath he announced to his friends the impending war on all the Papal ordinances.[1124] Thus, even previous to the Leipzig Disputation, he must have busied himself with his new idea of the Church. It was, however, only during the Disputation that, pressed hard by Eck, he was induced to deny openly the Primacy and to proclaim his belief in an invisible Church controlled by no authority.[1125] In the Disputation on July 4 and the following days, he attacked the divine institution of the Pope’s authority, asserted that even Œcumenical Councils could err, and, on July 6, declared that the Council of Constance had actually done so in rejecting the doctrine of Hus that there is “a Holy Catholic Church which is the whole body of the elect.”
