In the autumn of 1520 it was said that, near Mayence, Hutten had fallen upon the Papal Nuncios Marinus Caraccioli and Hieronymus Aleander, who were on their way to the Diet at Worms; Luther believed the report, which was as a matter of fact incorrect, that Hutten had attacked the Nuncios and that it was only by chance that the plot miscarried. “I am glad,” he wrote at that time, “that Hutten has led the way. Would that he had caught Marinus and Aleander!”[13]

Luther’s threats to use brute force soon became a cause of annoyance, even to certain of his admirers. We see this from a friendly warning which Wolfgang Capito addressed to him in the same year, namely, 1520. After recommending a peaceable course of action he says to him: “You affright your devoted followers by hinting at mercenaries and arms. I think I understand the reason of your plan, but I myself look upon it in a different light.” Capito advises Luther to proceed in a conciliatory manner and with deliberation. “Do not preach the Word of Christ in contention, but in charity.”[14]

He had thus been forewarned when he received from Hutten, that turbulent combatant, a confidential account of his work and a request to use his influence with the Elector in order that the latter might be induced to lend his assistance to him and his party; the Prince was “either to give help to those who had already taken up arms or at least, in the interests of the good cause, to shut his eyes to what was going on, and allow them to take refuge in his domains should the condition of things call for it.”[15] Hutten, with his proposed alliance, became more and more importunate. To such lengths Luther was, however, not inclined to go; he prized too highly the favour in which he stood with his sovereign to be willing to admit that he was in favour of civil war or a supporter of questionable elements. In his reply he thought it necessary to declare himself averse to the use of arms, notwithstanding the fact that he hailed with joy Hutten’s literary attacks which, according to his own expression, “would help to overthrow the Papacy more speedily than could have been anticipated.”[16] We learn from his own lips that he wrote to Hutten, saying, “he did not wish to carry on the struggle for the Gospel by means of violence and murder.” Writing of this to his friend Spalatin, at Worms, he adds a reflection, intended for the benefit of the court: “The world has been conquered, and the Church preserved by the Word, and through the Word it will be renewed. Antichrist who rose to power without human assistance will also be destroyed without human means, namely, by the Word.”[17]

On the other hand, in a letter to Staupitz, who was already at that time staying at Salzburg, he again makes much of the importance of Hutten’s and his friends’ literary work for the advance of the new teaching. “Hutten and many others are writing bravely for me.... Our Prince,” he adds, “is acting wisely, faithfully and steadfastly,” and as a proof of the favour of the Ruler of the land he mentions that he is bringing out a certain publication in Latin and German at his request.[18]

“The Prince is acting faithfully and steadfastly,” such was probably the principal reason why Luther refrained from joining the forward movement as advocated by the Knights of the Empire. The clever Elector was opposed to any violent method of procedure and was unwilling to have his fidelity to the Empire unnecessarily called in question. To Luther, moreover, his favour was indispensable, as it was of the utmost importance to him, in the interests of his aims, to be able to continue his professional work at Wittenberg and to spread abroad his publications unhindered from so favourable a spot. He was also not of such an adventurous disposition as to anticipate great things from the chimerical enterprise proposed by Hutten’s Knights. He was, however, aware that the religious revolution he was furthering lent the strongest moral assistance to the liberal tendencies of the Knights, and he on his part was very well satisfied with the moral help afforded by their party. His coquetting with this party was, nevertheless, a dangerous game for Germany. As is well known, Sickingen appealed in exoneration of his deeds of violence, and Hutten in defence of his vituperation, to the new gospel which had recently sprung up in the German land.

Efforts have frequently been made to represent Luther as treating the efforts of the party opposed to the Empire with sublime contempt. But it is certain “he was as little indifferent to the enthusiastic applause of the Franconian Knight [Hutten] as to the offers of protection and defence made him by Franz von Sickingen and Silvester von Schauenberg, the favourable criticism of Erasmus and other Humanists, the encouraging letters of the Bohemian Utraquists, the growing sympathy of German clerics and monks, the commotion among the young students, and the news of the growing excitement amongst the masses. He recognised more and more clearly from all these signs that he was not standing alone.”[19]

His language becomes, in consequence, stronger, his action bolder and more impetuous. He casts aside all scruples of ecclesiastical reverence for the primacy of Peter which still clung to him from Catholic times and he seeks to arrogate to himself the rôle of spokesman of the German nation, more particularly of the universal discontent with the exactions of Rome. Both are vividly expressed in his book “Von dem Bapstum tzu Rome” which he wrote in May, 1520, and which left the press already in June.

He addressed his book “Von dem Bapstum tzu Rome” to a very large circle, viz. to all who hitherto had found peace of conscience and a joyous assurance of salvation in fidelity to the Church and the Papacy. He sought to prove to them that they had been mistaken, that the Church is merely a purely spiritual kingdom; that the riches of this kingdom are to be obtained simply by faith without the intervention of priestly authority or the hierarchy; that God’s Kingdom is not bound up with communion with Rome; that it exists wherever faith exercises its sway; that such a spiritual commonwealth could have no man as its head, but only Christ. Ecclesiastical authority is to him no longer what he had at first represented it, an authority to rule entrusted to the clerical state, but a gracious promise of Divine forgiveness and mercy to consciences seeking salvation. His new dogmatic or psychological standpoint, with its tendency to tranquillise the soul, is noticeable throughout.

In the same work he deals angrily with the prevailing financial complaints of the Germans against Rome. He tells the people, in the inflammatory language of Hutten and Sickingen, that in Rome the Germans are looked upon as beasts, that the object there is to cheat the “drunken Germans” of their money by every possible thievish trick from motives of avarice. “Unless the German princes and nobles see to it presently, Germany will end in becoming a desert, or be forced to devour itself.”[20] A prediction which was sadly verified in a different sense, indeed, from that which Luther meant, though largely owing to his action. The German princes and nobles did indeed do their share in reducing Germany to a state of desolation, and the misery of the Thirty Years’ War stamped its bloody seal on Luther’s involuntary prophecy.

In the same year, 1520, Luther hurled his so-called “great reforming writings,” “An den Adel” and “De captivitate babylonica,” into the thick of the controversy. They mark the crisis in the struggle before the publication of the Bull of Excommunication.
