Luther at Worms is the most pregnant and momentous fact in our history, and the problem is to know why he so rigidly repelled the advances of the confessor, of the Chancellor of Baden, and the Elector of Treves. Was it simply the compelling logic of Protestantism, or was there some private saltpetre of his own, a programme drawn from his personality and habits of mind? There was no question at issue which had not either been pronounced by him insufficient for separation, or which was not abandoned afterwards, or modified in a Catholic sense by the moderating hand of Melanchthon. That happened to every leading doctrine at Augsburg, at Ratisbon, or at Leipzig. Predestination was dropped. The necessity of good works, the freedom of the will, the hierarchical constitution, the authority of tradition, the seven sacraments, the Latin mass, were admitted. Melanchthon confessed that he held all Roman doctrine, and that there was no difference except as to the celibacy of the clergy and communion under both kinds; the rest was the work of agitators; and he bitterly resented Luther's tyrannical treatment. As Melanchthon had the making of the official statements of doctrine, it would almost appear as if Luther never became a Lutheran. And the truth is that he held one doctrine which he never succeeded in imposing, and which forbade all approach and all endeavours to explain. For he believed that the Pope was anti-Christ. The idea came to him from Lorenzo Valla, whose tract on the Donation was published in 1518 by Hutten. He became convinced almost immediately after writing to Leo that deferential letter which he had agreed upon with Miltitz. It obliged him to force on a breach at Worms. His main objection to the Confession of Augsburg was that this article was excluded from it. Under the malediction of Church and State, Luther was lost sight of for some months. He was hidden in the Wartburg, the castle of his Elector, above Eisenach, disguised as a country gentleman. He wore a moustache, dined joyously, carried a sword, and shot a buck. Although his abode was unknown, he did not allow things to drift. The Archbishop of Mentz had been a heavy loser by the arrest of his indulgence, and he took advantage of the aggressor's disappearance to issue a new one. He was friendly to Luther, and repressed preaching against him; and the Elector of Saxony ordered that the controversy should not be revived. Luther replied that he would destroy the Elector rather than obey him; the Thesis had been posted in vain, and the spirit of Tetzel was abroad once more; he gave the Archbishop a fortnight, after which he would let the world see the difference between a bishop and a wolf. The prelate gave way, and having arrested one of his priests, who had married, he consented, at the reformer's request, to release him.
