We likewise find attacks on the Catholic fraction of the German nation, mingled with exhortations to resist the Turks, in a Preface he composed in 1530, on the occasion of the republication of an older work dating from Catholic times, “On the Morals and Religion of the Turks.”[208] The struggle raging in the heart of Germany, and the opposition of the Protestant Princes and Estates to the Emperor as head of the Realm, constituted the greatest obstacle to any scheme for united and vigorous action against the Turks. Hence to some extent Luther was indirectly responsible for the growth of the Ottoman Empire. On one occasion Luther gave vent to the following outburst: “Would that we Germans stood shoulder to shoulder, then it would be easy for us to resist the Turk. If we had 50,000 foot and 10,000 horse constantly in the field ... we could well withstand them and defend ourselves.”[209] The Sultan had, long before, taken into his calculations the dissensions created by Luther in the Empire.[210] On one occasion, about 1532, as we know from Luther’s “Talk Table,” Suleiman made enquiries of a German named Schmaltz, who was attached to an embassy, concerning Luther’s circumstances, and asked how old he was. To the answer that he was forty-eight years of age he replied: “I would he were still younger, for he would find a gracious master in me.” Luther, when this was reported to him, made the sign of the cross and said: “May God preserve me from such a gracious master.”[211] Luther, as we shall see below, had occasion to write against the Turks even at a later date. His writings had, however, no widespread influence; they were read only by one portion of the German nation, being avoided by the rest as works of an arch-heretic. Many marvelled at his audacity in presuming to teach the whole nation, and at his speaking as though he had been the leader of the people. Catholics were inclined, as Luther himself complains, to regard the growth of the Turkish power as God’s chastisement for the apostasy of a part of Germany and for the Emperor’s remissness in the matter of heresy.
