In June 1520, after a year's deliberation, Luther was condemned as the teacher of forty-one heresies; and in January, after he had made a bonfire of the Papal Bull and of the Canon Law, he was excommunicated. According to imperial constitutions three centuries old, the next step was that the civil magistrate, as the favourite phrase was, would send the culprit through the transitory flames of this world to the everlasting flames of the next. If that was not done, it might come to pass that the zeal of Prierias, Cajetan, and Eck would serve to inform the world that the medieval reign was over, and that the pen of an angry, rude, and not very learned monk was stronger than the Papacy and the Empire. It was known from the first that the Elector of Saxony would defend Luther, without being a Lutheran. Indeed, he shocked him by his zeal for indulgences and his collection of 19,000 relics. But he protected Luther as the most famous teacher of his university. They never met, and when the Elector on his deathbed sent for him, Luther was away. Since the Disputation of Leipzig he was the most conspicuously popular man in Germany. What he had said about the use and abuse of indulgences had not inflamed the nation. But the appeal to Scripture was definite and clear, and it met many objections and many causes of opposition.
When Luther was discussing the value of indulgences here and in the other world he meant no more and saw no farther. But now he saw the chasm, and possessed a principle on which to found his theology, his ethics, his politics, his theory of Church and State, and he proceeded to expound his ideas thoroughly in three celebrated works, known as his Reformation Tracts, which appeared in 1520. Luther's fundamental doctrine had come to him in early life, not from books, but from a friend. When all the efforts and resources of monastic criticism had led him only to despair, one of the brethren told him that his own works could not bring relief from the sense of unforgiven sin, but only faith in the merits of Christ. He found such comfort in this idea, which became the doctrine of imputation, and he grasped it with such energy that it has transformed the world. Predestination seemed to follow logically, and the rejection of free-will; and, as the office of the ordained priest became superfluous, the universal priesthood, with the denial of Prelacy. All this was fully worked out in the writings of 1520.
Luther was unconscious at first of the tremendous revolution he was preparing, because he found satisfaction in the strong language of St. Bernard. Under the shadow of the greatest doctor of the medieval church he felt assured of safety. And when he spoke of the Bible only, that was not textually more than had been said by Scotus and others, such as Erasmus, and quite lately the Bishop of Isernia at the Lateran Council. He did not start with a system or an apostolate; but now that his prodigious power as a writer of German had been revealed, he rejoiced in the conflict. He obtained his opportunity at the Diet of Worms. The young Emperor had come over from Spain to receive the crown, and he had accepted the Bull of Leo against Luther. At that moment he was on friendly terms with Rome, but his chancellor, Gattinara, warned him that the people throughout Germany favoured the reformer; and Tunstall wrote to Wolsey that 100,000 men would give their lives rather than let him be sacrificed to the Papacy. Even at Mentz, an episcopal city, the Nuncio Aleander was in danger of being stoned. "The conflicts of Church and State in the Middle Ages," he wrote, "were child's play to this." Therefore, although Luther had been condemned and excommunicated for forty heresies, although he had publicly thrown the Pope's Bull into the fire, and was worthy of death by ecclesiastical and municipal law, the Emperor gave him a free pass to the Diet and back, and sent a herald to arrange the journey.
At Erfurt, on his way, he learnt for the first time how the country was with him. When within sight of the towers and spires of Worms, he was warned by the Saxon minister Spalatin that his life would not be safe; and he returned the famous answer that he would go on if every tile in the city was a devil. At Oppenheim, almost the last stage, Bucer was waiting his arrival with a strange and unexpected message. A French Franciscan, Glapion, was the Emperor's confessor, and he was staying at Sickingen's castle, a few miles off, in company with Sickingen himself, the dreaded free-lance, with Ulrich von Hutten and with the unfrocked Dominican Bucer, who was to prove the ablest of the German reformers next to Luther. He sent Bucer, with an escort of Sickingen's troopers, to invite Luther to visit him there before he proceeded to Worms. It was clear that the Diet would end with a repulse for authority. The very presence there of a man who had written with such violence, and had been so solemnly condemned, was a defiance. Glapion was a reforming Catholic, and desired the assistance of Luther. He was clever enough to find ground in common with Erasmus, Ulrich von Hutten, and Bucer, and he was ready with far-reaching concessions to secure Luther. Then, he thought, his Emperor would be enabled to purify the Church. Bucer was of opinion that there was nothing to prevent agreement if Luther would interpret his contested writings as Bucer had explained them to Glapion. Gattinara was urgent for a reforming Council; the union of so many forces would be enough to invigorate the Italian cardinals, and they could carry Rome with them. It was the party of Reform attempting to conciliate the party of Reformation, that they might co-operate in saving the work of the Renaissance and renewing the Church from within. By renouncing "The Babylonish Captivity" alone of his numerous writings, Luther, who had already revoked so many utterances, might obtain acceptance for his main dogma, and bind the united Humanists and the Imperial government to his cause. Those were the terms of the proposed alliance. They were at once rejected.
Luther owed much to Erasmus, but they could never combine. He looked upon the purpose of the other as essentially rationalistic, Pelagian, and pagan. He foresaw that the coming struggle would be not with the old school, but with the new; that the obstacle to the Reformation was the Renaissance, and the enemy's name Erasmus. The Franciscan's profound and dazzling scheme miscarried, and Luther appeared before the Diet. Prompted by Glapion, the Imperial spokesman took no notice of Luther's own specific views, or of the Papal Bull against them. But he invited him to dissociate himself from Wyclif and John Hus on those matters which had been censured at Constance. That Council was the venerated safeguard of Catholic and Imperial reformers, and the strongest weapon of opposition to Rome. A Council which compelled the Emperor to burn a divine alive, after giving him a safe-conduct, was in no good odour just then with Luther, standing by the waves of the Rhine, which swept the ashes of John Hus away into oblivion. They then represented to Luther that the Diet was on his side, against Roman encroachments and the theory of penance; they praised his writings generally, and proposed that unsettled matters should be left to the decision of a future Council. To this he was willing to agree. But he stipulated that there should be no judgment except by the standard of Scripture. They replied that it stood to reason, and could not be made the object of a special condition. They meant different things, and the discussion came to naught. But important concessions had been made, and many opportunities had been offered, for the Diet was drawing up "the grievances of the German nation," and for that policy he was a desirable ally. Luther declined to concede anything, and a month later the Emperor signed the sentence of outlawry. In his Spanish dominions he was a jealous upholder of the Inquisition, even against the Pope, and of all the princes at Worms, secular or ecclesiastical, he was the most hostile and the most impatient.
Meanwhile Luther had gone back to Saxony, had preached on his way to the Benedictines of Hersfeld, and then disappeared in the Thuringian Forest. It was reported that he was dead; that his body had been found with a sword through it. When Charles V was dying, a baffled and disappointed man, he is said to have lamented that he kept his word to the turbulent friar who had triumphantly defied him. But Leo X sent orders that the passport should be respected and that the traveller should depart in peace.
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.
The most important result of the stay at the Wartburg was the translation of the New Testament, which was begun towards the end of the year, and was completed in about three months. There were already eighteen German Bibles, and he knew some of them, for a particular blunder is copied from an edition of 1466. All those that I have seen, and I have seen nearly all in Dr. Ginsburg's collection, are unwieldy folios. Luther's translation was published at a florin and a half, and may now be had for sixty guineas. It was reprinted eighty-five times in eleven years. The text as we know it was revised by his friends twenty years later. It was his appeal to the masses, and removed the controversy from the Church and the school to the market-place. The language had to be modified for the people of the South, and almost rewritten for the North; but it ended by impressing central German as the normal type for the whole country. It was the first translation from the Greek, and it was the work of the greatest master of German.
During the eclipse at the Wartburg Leo X was succeeded by Adrian of Utrecht, the Regent of Spain, a man of learning and devout life, who proceeded to reverse his predecessor's policy. He addressed a Brief to the Diet at Nuremberg, saying that of all those in authority at Rome none were without reproach, and the evils from which the Church was suffering had been caused and propagated by the papal court. To this memorable exhibition of integrity his envoy added that Luther deserved to be idolised if he had been content with the exposure of abuses, and that the real offender was Leo X. This change of front removed the charge from the outer branch to the centre. Luther had been hitting the wrong man. It was now avowed that the transgressor was not an obscure itinerant, but the sovereign pontiff himself, and that Luther's adversaries were in the wrong. Adrian had been Grand Inquisitor in four kingdoms, and he moderated expectation by inviting the Germans to be worthy of the illustrious example set by their ancestors, who burnt John Hus and Jerome of Prague. Therefore Erasmus, when summoned to Rome to advise with him, declined to come. "If they were going to shed blood," he said, "he would not be wanted."
