On April 16th, at ten o'clock in the morning, Luther entered Worms. He sat in an open carriage with his three companions from Wittenberg, clothed in his monk's habit. He was accompanied by a large number of men on horseback, some of whom, like Jonas, had joined him earlier in his journey; others, like some gentlemen belonging to the Elector's court, had ridden out from Worms to receive him. The imperial herald rode on before. The watchman blew a horn from the tower of the cathedral on seeing the procession approach the gate. Thousands streamed hither to see Luther. The gentlemen of the court escorted him into the house of the Knights of St. John, where he lodged with two counsellors of the Elector. As he stepped from his carriage he said, "God will be with me." Aleander, writing to Rome, said that he looked around with the eyes of a demon. Crowds of distinguished men, ecclesiastics and laymen, who were anxious to know him personally, flocked daily to see him.
On the evening of the following day he had to appear before the diet, which was assembled in the Bishop's palace, the residence of the Emperor, not far from where Luther was lodging. He was conducted thither by side streets, it being impossible to get through the crowds assembled in the main thoroughfare to see him. On his way into the hall where the diet was assembled, tradition tells us how the famous warrior, George von Frundsberg, clapped him on the shoulder and said: "My poor monk! my poor monk! thou art on thy way to make such a stand as I and many of my knights have never done in our toughest battles. If thou art sure of the justice of thy cause, then forward in the name of God, and be of good courage—God will not forsake thee." The Elector had given Luther as his advocate the lawyer Jerome Schurf, his Wittenberg colleague and friend.
When at length, after waiting two hours, Luther was admitted to the diet, Eck, the official of the Archbishop of Treves, put to him simply, in the name of the Emperor, two questions, whether he acknowledged the books—pointing to them on a bench beside him—to be his own, and next, whether he would retract their contents or persist in them. Schurf here exclaimed, "Let the titles of the books be named." Eck then read them out. Among them there were some merely edifying writings, such as A Commentary on the Lord's Prayer, which had never been made the subject of complaint.
Luther was not prepared for this proceeding, and possibly the first sight of the august assembly made him nervous. He answered in a low voice, and as if frightened, that the books were his, but that since the question as to their contents concerned the highest of all things, the Word of God and the salvation of souls, he must beware of giving a rash answer, and must therefore humbly entreat further time for consideration. After a short deliberation the Emperor instructed Eck to reply that he would, out of his clemency, grant him a respite till the next day.
So Luther had again, on April 18th, a Thursday, to appear before the diet. Again he had to wait two hours till six o'clock. He stood there in the hall among the dense crowd, talking unconstrained and cheerfully with the ambassador of the diet, Peutinger, his patron at Augsburg. After he was called in, Eck began by reproaching him for having wanted time for consideration. He then put the second question to him in a form more befitting and more conformable with the wishes of the members of the diet: "Wilt thou defend all the books acknowledged by thee to be thine, or recant some part?" Luther now answered with firmness and modesty, in a well-considered speech. He divided his works into three classes. In some of them he had set forth simple evangelical truths, professed alike by friend and foe. Those he could on no account retract. In others he had attacked corrupt laws and doctrines of the papacy, which no one could deny had miserably vexed and martyred the consciences of Christians, and had tyrannically devoured the property of the German nation: if he were to retract these books, he would make himself a cloak for wickedness and tyranny.
In the third class of his books he had written against individuals who endeavored to shield that tyranny and to subvert godly doctrine. Against these he freely confessed that he had been more violent than was befitting. Yet even these writings it was impossible for him to retract without lending a hand to tyranny and godlessness. But in defence of his books he could only say in the words of the Lord Jesus Christ: "If I have spoken evil, bear witness of the evil; but if well, why smitest thou me?" If anyone could do so, let him produce his evidence and confute him from the sacred writings, the Old Testament and the Gospel, and he would be the first to throw his books into the fire. And now, as in the course of his speech he had sounded a new challenge to the papacy, so he concluded by an earnest warning to Emperor and empire, lest, by endeavoring to promote peace by a condemnation of the divine Word, they might rather bring a dreadful deluge of evils, and thus give an unhappy and inauspicious beginning to the reign of the noble young Emperor. He said not these things as if the great personages who heard him stood in any need of his admonitions, but because it was a duty that he owed to his native Germany, and he could not neglect to discharge it.
Luther, like Eck, spoke in Latin, and then, by desire, repeated his speech with equal firmness in German. Schurf, who was standing by his side, declared afterward with pride, "how Martin had made this answer with such bravery and modest candor, with eyes upraised to heaven, that he and everyone were astonished."
The princes held a short consultation after this harangue. Then Eck, commissioned by the Emperor, sharply reproved him for having spoken impertinently and not really answered the question put to him. He rejected his demand that evidence from Scripture might be brought against him by declaring that his heresies had already been condemned by the Church, and in particular by the Council of Constance, and such judgments must suffice if anything were to be held settled in Christianity. He promised him, however, if he would retract the offensive articles, that his other writings should be fairly dealt with, and finally demanded a plain answer "without horns" to the question whether he intended to adhere to all he had written or would retract any part of it?
To this Luther replied he would give an answer "with neither horns nor teeth." Unless he were refuted by proofs from Scripture, or by evident reason, his conscience bound him to adhere to the Word of God which he had quoted in his defence. Popes and councils, as was clear, had often erred and contradicted themselves. He could not, therefore, and he would not, retreat anything, for it was neither safe nor honest to act against one's conscience.
Eck exchanged only a few more words with him in reply to his assertion that councils had erred. "You cannot prove that," said Eck. "I will pledge myself to do it," was Luther's answer. Pressed and threatened by his enemy, he concluded with the famous words: "Here I stand, I can do no otherwise. God help me. Amen."
