Luther was never afterwards to revert to his original disapproval of armed resistance to the Emperor.

In his private conversations we frequently find, on the contrary, frank admissions quite in agreement with the above remark on “war and rebellion” being justified by the Divine and indestructible Evangel. It is not only lawful, he says, but necessary to fight against the Emperor in the cause of the Evangel. “Should he begin a war against our religion, our worship and our Church, then he is a tyrant. Of this there is no question. Is it not lawful to fight in defence of piety? Even nature demands that we should take up arms in defence of our children and our families. Indeed, I shall, if possible, address a writing to the whole world exhorting all to the defence of their people.”[175]

Other similar statements are met with in his Table-Talk at a later date. “It is true a preacher ought not to fight in his own defence, for which reason I do not take a sword with me when I mount the pulpit, but only on journeys.”[176] “The lawyers,” he said, on February 7, 1538, “command us to resist the Emperor, simply desiring that a madman should be deprived of his sword.... The natural law requires that if one member injure another he be put under restraint, made a prisoner and kept in custody. But from the point of view of theology, there are doubts (Matt. v., 1 Peter ii.). I reply, however, that statecraft permits, nay commands, self-defence, so that whoever does not defend himself is regarded as his own murderer,” in spite of the fact, that, as a Christian and “believer in the Kingdom of Christ, he must suffer all things, and may not in this guise either eat or drink or beget children.” In many cases it is necessary to put away “the Christianum and bring to the fore the politicam personam,”[177] just as a man may slay incontinently the violator of his wife. “We are fighting, not against Saul, but against Absalom.” Besides, the Emperor might not draw the sword without the consent of the Seven Electors. “The sword belongs to us, and only at our request may he use it.”[178] “Without the seven he has no power; indeed, if even one is not for him, his power is nil and he is no longer monarch.... I do not deprive the Emperor of the sword, but the Pope, who has no business to lord it and act as a tyrant.”[179] “The Emperor will not commence a war on his own account but for the sake of the Pope, whose vassal he has become; he is only desirous of defending the abominations of the Pope, who hates the Gospel and thinks of nothing but his own godless power.”[180]

Luther, in his anger against the Papists and the priests, goes so far as to place them on a par with the Turks and to advise their being slaughtered;[181] this he did, for instance, in May, 1540. In 1539 he says: “Were I the Landgrave, I should set about it, and either perish or else slay them because they refuse peace in a good and just cause; but as a preacher it does not beseem me to counsel this, much less to do it myself.”[182] The Papal Legate, Paolo Vergerio, when with Luther in 1535, expressed to him his deep indignation at the deeds of King Henry VIII. of England, who had put to death Cardinal John Fisher and Sir Thomas More. Luther wrote to Melanchthon of Vergerio’s wrath and his threats against the King, but shared his feelings so little as actually to say: “Would that there were a few more such kings of England to put to death these cardinals, popes and legates, these traitors, thieves, robbers, nay, devils incarnate.” Such as they, he says, plunder and rob the churches and are worse than a hundred men of the stamp of Verres or a thousand of that of Dionysius. “How is it that Princes and lords, who are always complaining to us of the injury done to the churches, endure it?”[183]

Even in official memoranda Luther soon threw all discretion to the winds, and ventured to speak most strongly in favour of armed resistance.

Such was the memorandum, of January, 1539, addressed to the Elector Johann Frederick and signed at Weimar by Jonas, Bucer and Melanchthon, as well as Luther. The Elector had asked for it owing to the dangerous position of the League of Schmalkalden, now that peace had been concluded between the Emperor and Francis I. of France. He had also enquired how far the allies might take advantage of the war with the Turks; and whether they might make their assistance against the Turks contingent upon certain concessions being granted to the new worship. The second question will be dealt with later;[184] as to the first, whether resistance to the Emperor was allowed, the signatories replied affirmatively in words which go further than any previous admission.[185]

They had already, they say, “given their answer and opinion, and there was no doubt that this was the Divine truth which we are bound to confess even at the hour of death, viz. that not only is defence permitted, but a protest is verily, and indeed, incumbent on all.” Here it will be observed that Luther no longer says merely that the lawyers inferred this from the Imperial law, but that God, “to Whom we owe this duty,” commanded that “idolatry and forbidden worship” should not be tolerated. Numerous references to the “Word of God” regarding the authorities were adduced in support of this contention (Ps. lxxxii. 3; Exod. xx. 7; Ps. ii. 10, 11; 1 Tim. i. 9). It is pointed out how in the Sacred Books the “Kings of Juda are praised for exterminating idolatry.” “Every father is bound to protect his wife and child from murder, and there is no difference between a private murderer and the Emperor, should he attempt unjust violence outside his office.” The case is on all fours with one where the “overlord tries to impose on his subjects blasphemy and idolatry,” hence war must be waged, just as “Constantine fell upon Licinius, his ally and brother-in-law.” David, Ezechias and other holy kings likewise risked life and limb for the honour of God. “This is all to be understood as referring to defence.” But “where the ban has been proclaimed against one or more of the allies,” “discord has already broken out.” Those under the ban have lost “position and dignity,” and may commence the attack without further ado. Still, “it is not for us to assume that hostilities should be commenced at once”; this is the business of those actually concerned.

Such was the advice of Luther and those mentioned above to the Elector, when he was about to attend a meeting of the League of Schmalkalden at Frankfurt, where another attempt was to be made to prevent the outbreak of hostilities by negotiations with the Emperor’s ministers. Luther was apprehensive of war as likely to lead to endless misfortunes, yet his notion that “idolatry” must be rooted out would allow of no yielding on his part. “It is almost certain that this memorandum was made use of at the negotiations preliminary to the Frankfurt conference, seeing that the Elector in the final opinion he addressed to his councillors repeats it almost word for word.”[186] The memorandum was probably drawn up by Melanchthon.
