The contrary “delusion,” he says, had been invented and encouraged by the preachers, whose proceedings were infinitely worse than any mere “numbering of the people.” He storms against the clergy and vigorously foments the social discontent. To build churches, or found livings, etc., was mere outward show; “such works simply gave rise to avarice, desire for the praise of men and other vices.” “You think that as a priest you are free from sin, and yet you nourish so much jealousy in your heart; if you could slay your neighbour with impunity you would do so and then go on saying Mass. Surely it would not be surprising were a thunderbolt to smite you to the earth.” In order to complete the effect of this demagogic outburst he mocks at the sermons, with their legends “about the old ass,” etc., and their quotations from ancient philosophers, who were “not only against the Gospel, but even against God Himself.” The result was stupendous, especially in the case of the young men at the University whom the Humanists had disposed in Luther’s favour. On the day after Luther’s departure one of his sympathisers, a Canon of the Church of St. Severus, who had taken part in the solemn reception accorded Luther on his arrival in the town, was told by the Dean, Jakob Doliatoris, that he was under excommunication and might no longer attend the service in choir. On his complaining to the University, of which he was a member, the students intervened with demonstrations in his favour.[997] Luther heard of this only through certain unreliable reports and wrote to Spalatin: “They apprehend still worse things at Erfurt. The Senate pretends to see nothing of what is going on. The clergy are reviled. The young apprentices are said to be in league with the students. We are about to see the prophecy fulfilled: ‘Erfurt has become a new [Husite] Prague.’” Previous to this, in the same letter, he had said of his adversaries in the Empire: “Let them be, perhaps the day of their visitation is at hand.”[998] Soon after, however, he became rather more concerned, perhaps owing to further reports of the unrest, and began to fear for the “good name and progress of the Evangel,” in consequence of the acts of brutality committed. “It is indeed quite right,” he wrote to Melanchthon, “that those who persist in their impiety should have their courage cooled,” but in this “Satan makes a mockery of us”; he sees in a mystical vision “The Judgment Day,” the approaching end of the world at Erfurt, and the fig tree, as had been foretold, growing up, covered with leaves, but bare of fruit because the cause of the Evangel could not make its way.[999] In July, 1521, there broke out in the town the so-called “Pfaffensturm.”
