A recent Protestant biographer of Carlstadt’s laments the “frightful harshness of his (Luther’s) polemics.” “How deep the traces left by his mode of controversy were, ought not to be overlooked,” so he writes. “From that time forward this sort of thing took the place of any real discussion of differences of opinion between members of the Lutheran camp, nor did people even seem aware of how far they were thus drifting from the kindliness and dignity of Christian modes of thought.”[388] What is here said of the treatment of opponents within the camp applies even more strongly to Luther’s behaviour towards Catholics. The following episode of his habitual persecution of Albert, Archbishop and Elector of Mayence, illustrates this very well. On June 21, 1535, the Archbishop in accordance with the then law and with the sentence duly pronounced by the judge, had caused Hans von Schönitz, once his trusted steward, to be executed; the charge of which he had been proved guilty was embezzlement on a gigantic scale. The details of the case, which was dealt with rather hurriedly, have not yet been adequately cleared up, but even Protestant researchers agree that Schönitz deserved to be dealt with as a “public thief,”[389] seeing that “in the pecuniary transactions which he undertook for Albert he was not unmindful of his own advantage”;[390] “there is no doubt that he was rightly accused of all manner of peculation and cheating.”[391] Luther, however, furiously entered the lists on behalf of the executed man and against the detested Archbishop who, in spite of his private faults, remained faithful to the Church and was a hindrance to the spread of Lutheranism in Germany. Luther implicitly believed all that was told him, of Hans’s innocence and of Albert’s supposed abominable motives, by Schönitz’s brother and his friend Ludwig Rabe—who himself was implicated in the matter—and both of whom came to Wittenberg. “Both naturally related the case from their own point of view.”[392] Luther sent two letters to the Cardinal, one more violent than the other.[393] The second would seem to have been intended for publication and was sent to the press, though at present no copy of it can be discovered. In it in words of frightful violence he lays at the door of the Prince of the Church the blood of the man done to death. The Archbishop was a “thorough-paced Epicurean who does not believe that Abel lives in God and that his blood still cries more loudly than Cain, his brother’s murderer, fancies.” He, Luther, like another Elias, must call down woes “upon Achab and Isabel.” He had indeed heard of many evil deeds done by Cardinals, “but I had not taken your Cardinalitial Holiness for such an insolent, wicked dragon.... Your Electoral Highness may if he likes commit a nuisance in the Emperor’s Court of Justice, infringe the freedom of the city of Halle, usurp the sword of Justice
