But, nevertheless, the views of Carlstadt found advocates, and his extravagances were copied with still greater zeal. Many pretended to special divine illumination--the great central principle of all fanaticism. Among these was Thomas Muenzer, of Zwickau, mystical, ignorant, and conceited, but sincere and simple hearted. "Luther," said he, "has liberated men's consciences from the papal yoke, but has not led them in spirit towards God." Considering himself as called upon by a special revelation to bring men into greater spiritual liberty, he went about inflaming the popular mind, and raising discontents, and even inciting to a revolt. Religion now became mingled with politics, and social and political evils were violently resisted, under the garb of religion. An insurrection at last arose in the districts of the Black Forest, (1524,) near the sources of the Danube, and spread from Suabia to the Rhine provinces, until it became exceedingly formidable. Then commenced what is called the "peasants' war," which was only ended by the slaughter of fifty thousand people. As the causes of this war, after all, were chiefly political, the details belong to our chapter on political history. For this insurrection of the peasantry, however, Luther expressed great detestation; although he availed himself of it to lecture the princes of Germany on their duties as civil rulers. The peasant war was scarcely ended, when Luther married Catharine Bora; and, as she was a nun, and he was a monk, the marriage gave universal scandal. But this marriage, which proved happy, was the signal of new reforms. Luther now emancipated himself from his monastic fetters, and lifted up his voice against the whole monastic system. Eight years had elapsed since he preached against indulgences. During these eight years, reform had been gradual, and had now advanced to the extreme limit it ever reached during the life of the reformer. But, in another quarter, it sprang up with new force, and was carried to an extent not favored in Germany. It was in Switzerland that the greatest approximation was made to the forms, if not to the spirit, of primitive Christianity. [Sidenote: Ulric Zwingle.]
