The pope, hitherto mild, persuasive, and undecided, now arose in the majesty of his mighty name, and, as the successor of St. Peter, hurled those weapons which had been thunderbolts in the hands of the Gregories and the Innocents. From his papal throne, and with all the solemnity of God's appointed vicegerent, he denounced the daring monk of Wittemberg, and sentenced him to the wrath of God, and to the penalty of eternal fire. Excommunication of Luther. Luther was excommunicated by a papal bull, and his writings were condemned as heretical and damnable.

This was a dreadful sentence. Few had ever resisted it successfully, even monarchs themselves. Excommunication was still a fearful weapon, and used only in desperate circumstances. It was used only as the last resort; for frequency would destroy its power. In the middle ages, this weapon was omnipotent; and the middle ages had but just passed away. No one could stand before that awful anathema which consigned him to the wrath of incensed and implacable Deity. Much as some professed to despise the sentence, still, when inflicted, it could not be borne, especially if accompanied with an interdict. Children were left unburied. The churches were closed. The rites of religion were suspended. A funereal shade was spread over society. The fears of hell haunted every imagination. No reason was strong enough to resist the sentence. No arm was sufficiently powerful to remove the curse. It hung over a guilty land. It doomed the unhappy offender, who was cursed, wherever he went, and in whatever work he was engaged.

But Luther was strong enough to resist it, and to despise it. He saw it was an imposition, which only barbarous and ignorant ages had permitted. Moreover, he perceived that there was now no alternative but victory or death; that, in the great contest in which he was engaged, retreat was infamy. Nor did he wish to retreat. He was fighting for oppressed humanity, and death even, in such a cause, was glory. He understood fully the nature and the consequence of the struggle. He perceived the greatness of the odds against him, in a worldly point of view. No man but a Luther would have been equal to it; no man, before him, ever had successfully rebelled against the pope. It is only in view of this circumstance, that his intrepidity can be appreciated.

What did the Saxon monk do, when the papal bull was published? He assembled the professors and students of the university, declared his solemn protest against the pope as Antichrist, and marched in procession to the gates of the Castle of Wittemberg, and there made a bonfire, and cast into it the bull which condemned him, the canon law, and some writings of the schoolmen, and then reëntered the city, breathing defiance against the whole power of the pope, glowing in the consciousness that the battle had commenced, to last as long as life, and perfectly secure that the victory would finally be on the side of truth. This was in 1520, on the 10th of December.

The attention of the whole nation was necessarily drawn to this open resistance; and the sympathy of the free thinking, the earnest, and the religious, was expressed for him. Never was popular interest more absorbing, in respect to his opinions, his fortunes, and his fate. The spirit of innovation became contagious, and pervaded the German mind. It demanded the serious attention of the emperor himself.

A great Diet of the empire was convened at The Diet of Worms. Worms, and thither Luther was summoned by the temporal power. He had a safe-conduct, which even so powerful a prince as Charles V. durst not violate. In April, 1521, the reformer appeared before the collected dignitaries of the German empire, both spiritual and temporal, and was called upon to recant his opinions as heretical in the eyes of the church, and dangerous to the peace of the empire. Before the most august assembly in the world, without a trace of embarrassment, he made his defence, and refused to recant. "Unless," said he, "my errors can be demonstrated by texts from Scripture, I will not and cannot recant; for it is not safe for a man to go against his conscience. Here I am. I can do no otherwise. God help me! Amen."

This declaration satisfied his friends, though it did not satisfy the members of the diet. Luther was permitted to retire. He had gained the confidence of the nation. From that time, he was its idol, and the acknowledged leader of the greatest insurrection of human intelligence which modern times have seen. The great principles of the reformation were declared. The great hero of the Reformation had planted his cause upon a rock. And yet his labors had but just commenced. Henceforth, his life was toil and vexation. New difficulties continually arose. New questions had to be continually settled. Luther, by his letters, was every where. He commenced the translation of the Scriptures; he wrote endless controversial tracts; his correspondence was unparalleled; his efforts as a preacher were prodigious. But he was equal to it all; was wonderfully adapted to his age and circumstances.

About this time commenced his Imprisonment at Wartburg. voluntary imprisonment at Wartburg, among the Thuringian forests: he being probably conducted thither by the orders of the elector of Saxony. Here he was out of sight, but not out of mind; and his retirement, under the disguise of a knight, gave him leisure for literary labor. In the old Castle of Wartburg, a great part of the Scriptures was translated into that beautiful and simple version, which is still the standard of the German language.

While Luther was translating the Scriptures, in his retreat, Wittemberg was the scene of new commotions, pregnant with great results. There were many of the more zealous converts to the reformed doctrines, headed by Carlstadt. Carlstadt, dean of the faculty of theology, who were not content with the progress which had been made, and who desired more sweeping and radical changes. Such a party ever exists in all reforms; for there are some persons who are always inclined to ultra and extravagant courses. Carlstadt was a type of such men. He was learned, sincere, and amiable, but did not know where to stop; and the experiment was now to be tried, whether it was possible to introduce a necessary reform, without annihilating also all the results of the labors of preceding generations. Carlstadt's mind was not well balanced, and to him the reformation was only a half measure, and a useless movement, unless all the external observances of religion and the whole economy of the church were destroyed. He abolished, or desired to abolish, all priestly garments, all fasts and holydays, all pictures in the churches, and all emblematical ceremonies of every kind. He insisted upon closing all places of public amusement, the abolition of all religious communities, and the division of their possessions among the poor. He maintained that there was no need of learning, or of academic studies, and even went into the houses of the peasantry to seek explanation of difficult passages of Scripture. For such innovations, the age was certainly not prepared, even had they been founded on reason; and the conservative mind of Luther was shocked at extravagances which served to disgust the whole Christian world, and jeopardize the cause in which he had embarked. So, against the entreaties of the elector, and in spite of the ban of the empire, he returned to Wittemberg, a small city, it was true, but a place to which had congregated the flower of the German youth. He resolved to oppose the movements of Carlstadt, even though opposition should destroy his influence. Especially did he declare against all violent measures to which the ultra reformers were inclined, knowing full well, that, if his cause were sullied with violence or fanaticism, all Christendom would unite to suppress it. His sermons are, at this time, (1522,) pervaded with a profound and conservative spirit, and also a spirit of conciliation and love, calculated to calm passions, and carry conviction to excited minds. His moderate counsels prevailed, the tumults were hushed, and order was restored. Carlstadt was silenced for a time; but a mind like his could not rest, especially on points where he had truth on his side. One of these was, in reference to the presence of Christ's body in the Eucharist, which Carlstadt totally denied. He taught "that the Lord's supper was purely symbolic, and was simply a pledge to believers of their redemption." But Luther saw, in every attempt to exhibit the symbolical import of the supper, only the danger of weakening the authority of Scripture, which was his stronghold, and became exceedingly tenacious on that point; carried his views to the extreme of literal interpretation, and never could emancipate himself from the doctrines of Rome respecting the eucharist. Carlstadt, finding himself persecuted at Wittemberg left the city, and, as soon as he was released from the presence of Luther, began to revive his former zeal against images also, and was the promoter of great disturbances. He at last sought refuge in Strasburg, and sacrificed fame, and friends, and bread to his honest convictions.

But, nevertheless, the views of Carlstadt found advocates, and his extravagances were copied with still greater zeal. Many pretended to special divine illumination—the great central principle of all fanaticism. Among these was Thomas Münzer. Thomas Münzer, of Zwickau, mystical, ignorant, and conceited, but sincere and simple hearted. "Luther," said he, "has liberated men's consciences from the papal yoke, but has not led them in spirit towards God." Considering himself as called upon by a special revelation to bring men into greater spiritual liberty, he went about inflaming the popular mind, and raising discontents, and even inciting to a revolt. Religion now became mingled with politics, and social and political evils were violently resisted, under the garb of religion. An insurrection at last arose in the districts of the Black Forest, (1524,) near the sources of the Danube, and spread from Suabia to the Rhine provinces, until it became exceedingly formidable. Then commenced what is called the "peasants' war," which was only ended by the slaughter of fifty thousand people. As the causes of this war, after all, were chiefly political, the details belong to our chapter on political history. For this insurrection of the peasantry, however, Luther expressed great detestation; although he availed himself of it to lecture the princes of Germany on their duties as civil rulers.
