In Münzer Luther looked for a near outbreak of the Evil Spirit. He alluded to him in his letter of June 18, as the 'Satan of Allstedt,' adding that he thought he was not yet quite fledged. He soon heard more about him, namely, that 'his Spirit was going to strike out with the fist.' On this subject he wrote the next month to the Elector Frederick and Duke John, and published his letter. Against Münzer's mere words--his preaching and his personal revilements--he was not now concerned to defend himself. 'Let them boldly preach,' he says, 'what they can.... Let the Spirits rend and tear each other. A few, perhaps, may be seduced; but that happens in every war. Wherever there is a battle and fighting, some one must fall and be wounded.' He repeats here, what he had said before, that Antichrist should be destroyed 'without hands,' and that Christ contended with the Spirit of His Word. But if they really meant to strike out with the fist, then Luther would have the prince say to them, 'Keep your fists quiet, for that is our office, or else leave the country.' In August Luther came himself to Weimar, in obedience to a wish expressed by the two princes. With the court-preacher he had come to a friendly understanding. Münzer had just left Allstedt, an official report of his dangerous proceedings having been forwarded from there to Weimar, whither he was summoned for an examination and inquiry. On August 14 Luther wrote from this town to the magistrate of Mühlhausen, where Münzer, as he heard, had taken refuge and had already mustered a party. He warned the people of Mühlhausen to wait at least before receiving Münzer, until they had heard 'what sort of children he and his followers were.' They would not remain long in the dark about him. He was a tree, as he had shown at Zwickau and Allstedt, which bore no fruit but murder and rebellion. From Weimar Luther travelled on to Orlamünde. On August 21 he arrived at Jena, where a preacher named Reinhard was staying with Carlstadt. Luther here preached against the 'Spirit of Allstedt,' which destroyed images, despised the sacrament, and incited to rebellion. Carlstadt, who was present and heard the sermon, waited on him afterwards at his lodging, to defend himself against these charges. Luther insisted, notwithstanding, that Carlstadt was 'an associate of the new prophets.' He challenged him finally to abandon his intrigues and confute him openly in writing, and the heated interview ended by Carlstadt promising to do so, and by Luther giving him a florin as a pledge and token of the bargain.
