Charles V. had at this time succeeded to the empire, and he convened his first diet of the sovereigns and states at Worms. The diet met in the beginning of 1521; an order was issued for the destruction of Luther's books, and he himself was summoned to appear before the diet. This was above all what he desired—to confess the truth before the assembled powers of Germany. He resolved—having received a safe-conduct—to obey the summons, come what would. All Germany was moved by his heroism; his journey resembled a triumph; the threats of enemies and the anxieties of friends alike failed to move him. "I am resolved to enter Worms," he said, "although as many devils should set at me as there are tiles on the housetops." His appearance and demeanor before the diet, and the firmness with which he held his ground and refused to retract, all make a striking picture. He was not allowed to defend his opinions. "Unless I be convinced," he said, "by Scripture and reason, I neither can nor dare retract anything, for my conscience is a captive to God's word, and it is neither safe nor right to go against conscience. There I take my stand. I can do no otherwise. So help me God. Amen."

On his return from Worms he was seized, at the instigation of his friend, the Elector of Saxony, and safely lodged in the old castle of the Wartburg. The affair was made to assume an aspect of violence, but in reality it was designed to secure him from the destruction which his conduct at Worms would certainly have provoked, he having been placed under the ban of the empire. He remained in this shelter for about a year, concealed in the guise of a knight. His chief employment was his translation of the Scriptures into his native language. He composed various treatises besides, and injured his health by sedentary habits and hard study. His imagination became morbidly excited, and he thought he saw and heard the Evil One mocking him while engaged in his literary tasks; the blot from the inkstand that he hurled at him is still shown on the wall of his chamber. The subject of the personality and presence of Satan was a familiar one with Luther, and he has many things about it in his Table-talk.

The disorders which sprang up in the progress of the Reformation recalled Luther to Wittenberg. He felt that his presence was necessary to restrain Carlstadt and others, and, defying any danger to which he might still be exposed, he returned in 1522 to the old scene of his labors, rebuked the unruly spirits who had acquired power in his absence, and resumed with renewed energy his interrupted work. He strove to arrest the excesses of the Zwickau fanatics, and counselled peace and order to the inflamed peasants; while he warned the princes and nobles of the unchristian cruelty of many of their doings, which had driven the people to exasperation and frenzy. At no period of his life is he greater than now, in the stand which he made against lawlessness on the one hand and tyranny on the other. He vindicated his claim to be a reformer in the highest sense by the wise and manly part which he acted in this great social crisis in the history of Germany. In this year also he published his acrimonious reply to Henry VIII. on the seven sacraments. Although he had been at first united in a common cause with Erasmus, estrangement had gradually sprung up between the scholar of Rotterdam and the enthusiastic reformer of Wittenberg. This estrangement came to an open breach in the year 1525, when Erasmus published his treatise "De Libero Arbitrio." Luther immediately followed with his counter-treatise "De Servo Arbitrio." The controversy raged loudly between them; and in the vehemence of his hostility to the doctrine of Erasmus, Luther was led into various assertions of a very questionable kind, besides indulging in the wild abuse of his opponent's character. The quarrel was an unhappy one on both sides; and it must be confessed there is especially a want of generosity in the manner in which Luther continued to cherish the dislike which sprang out of it.

In the course of the same year Luther married Katharina von Bora, one of nine nuns who, under the influence of his teaching, had emancipated themselves from their religious vows. The step rejoiced his enemies and even alarmed some of his friends, like Melancthon. But it greatly contributed to his happiness, while it served to enrich and strengthen his character. All the most interesting and touching glimpses we get of him henceforth are in connection with his wife and children.

Two years after his marriage he fell into a dangerous sickness and depression of spirits, from which he was only aroused by the dangers besetting Christendom from the advance of the Turks. Two years later, in 1529, he engaged in his famous conference at Marburg with Zwingli and other Swiss divines. The following year finds him at Coburg, while the diet sat at Augsburg. It was deemed prudent to intrust the interests of the Protestant cause to Melancthon, who attended the diet, but Luther removed to Coburg to be at hand for consultation. The drawing up of the Augsburg Confession marks the culmination of the German Reformation (1530); and the life of Luther from henceforth possesses comparatively little interest. He survived sixteen years longer, but they are years marked by few incidents of importance. He died at Eisleben on February 18, 1546, and was buried at Wittenberg.

Luther's character presents an imposing combination of great qualities. Endowed with broad human sympathies, massive energy, manly and affectionate simplicity, and rich, if sometimes coarse humor, he is at the same time a spiritual genius. His intuitions of divine truth were bold, vivid, and penetrating, if not comprehensive; and he possessed the art which God alone gives to the finer and abler spirits that He calls to do special work in this world, of kindling other souls with the fire of his own convictions, and awakening them to a higher consciousness of religion and duty. He was a leader of men, therefore, and a Reformer in the highest sense. His powers were fitted to his appointed task; it was a task of Titanic magnitude, and he was a Titan in intellectual robustness and moral strength and courage. It was only the divine energy which swayed him, and of which he recognized himself the organ, that could have accomplished what he did.

View him as a mere theologian, and there are others who take higher rank. There is a lack of patient thoughtfulness and philosophical temper in his doctrinal discussions; but the absence of these very qualities gave vigor to his bold, if sometimes crude, conceptions, and enabled him to triumph in the struggle for life and death in which he was engaged. To initiate the religious movement which was destined to renew the face of Europe, required a gigantic will, which, instead of being crushed by opposition, or frightened by hatred, should only gather strength from the fierceness of the conflict before it. To clear the air thoroughly, as he himself said, thunder and lightning are necessary. Upon the whole, it may be said that history presents few greater characters—few that excite at once more love and admiration, and in which we see tenderness, humor, and a certain picturesque grace and poetic sensibility more happily combined with a lofty and magnanimous, if sometimes rugged, sublimity.
