Apart from the doctrine on the Sacrament, the other thing which helped to annoy him stands revealed more plainly in the letter addressed on the same day to the Strasburg preachers: “We dare to boast that Christ was first made known by us, and now Zwingli actually comes and accuses us of denying Christ.”[1071] Bossuet was quite right in arguing that such petty jealousy on Luther’s part is scarcely to his credit.[1072] He quotes a criticism on Luther’s behaviour by George Calixt, the famous Lutheran professor of theology at Helmstädt: “The sweetness of vainglory is so seductive and human weakness so great, that even those who despise all things and risk their goods, yea life itself, may succumb to inordinate ambition.” Luther, too, had high aims; “we cannot be surprised that, even a man so large-minded as Luther, should have written such things to the people of Strasburg.”[1073] Offended vanity played a part as great and even more obvious in Luther’s furious polemics against the literary defenders of the Church. One cannot help noticing how, especially when they had succeeded in making out a clear case against him, his answer was a torrent of most unsparing abuse. * * * * * The eloquence which he had at his command also constituted a temptation. He was well aware of the force with which his impassioned language carried others away. Very little was thus needed to induce him to take up this formidable weapon which at least ensured his success among the masses. He himself revelled in the unquenchable wealth of his vituperative vocabulary, and with it he caught the fancy of thousands who loved nothing more than a quarrel. If it be true that all popular orators are exposed to the temptation to exaggerate, to say things which are striking rather than correct, and, generally, to court the applause of the crowd, this danger was even greater in Luther’s case owing to the whole character of the controversy he had stirred up. In the midst of a stormy sea one does not speak softly. Luther’s abuse was, however, powerful enough to be heard above even the most furious tempest. For his work Luther required an extraordinary stimulus. He would have succumbed under the countless and burdensome labours which devolved on him had he not constantly aroused himself anew by the exercise of a sort of violence. Vituperation thus became to him a real need. When he had succeeded thereby in working himself up into a passion his mind grew clearer and his imagination more vigorous, so that he found it all the easier to borrow from the lips of the mob that rude language of which he makes such fell use. He kindles his animation by dwelling on the “vermin and running sores of Popery.”
