The question, how far they were to be tolerated, or whether it would be better forcibly to suppress them was first brought home to Luther by the Anabaptist movement under Thomas Münzer. Sure of the upper hand, Luther decided, as we know, at the end of July, 1524, to advise the Saxon Princes to leave the Anabaptists in peace so far as their doctrines were concerned. “Let them preach as they please,” was his advice, for “there ‘must needs be heresies’” (1 Cor. xi. 19).[871] He explained to Lazarus Spengler of Nuremberg on Feb. 4, 1525, that the Anabaptists were not to be punished, particularly with “bodily penalties,” because, in his opinion, they were no real blasphemers, but merely “like the Turks or straying Christians.”[872] In May of the same year he showed himself disposed to universal toleration. “The authorities are not to hinder anyone from teaching and believing what he pleases”;[873] a principle which, as we have shown above (p. 239), he himself had contravened in practice as early as 1522, and was finally to set aside altogether. As for the Anabaptists, in 1527 Luther was not yet in favour of the “putting to death” and bloody “rooting out” of these sectarians. In 1528 he even taught in his exposition of the Parable of the Good Seed and the Tares that “we are not to fight the fanatics with the sword.”[874] What made him hesitate to advise the putting to death of these heretics was, as he told his friend Wenceslaus Link of Nuremberg in 1528, the apprehension that this might lead to abuses; he feared lest, in the time to come, we might turn the sword against the best “among us.”[875] But without a doubt he approved of the Edict of the Elector Johann (Jan. 17, 1528) which proscribed the writings of the Anabaptists, Sacramentarians and fanatics throughout the land—if indeed the Edict itself may not be traced directly to Luther, as Zwingli suspected.[876] In 1528 it also seemed to him right to decree the penalty of banishment in the case of the Anabaptists.[877] When, however, the danger had become more evident, which the Anabaptist heresy spelt both to the land-frith and the foundations of Christianity, not to speak of the Lutheran teaching, Luther adopted a sterner line of action.
