Such exhortations not to wage war against the Turks naturally tended to confuse the multitude to the last degree.
Incautious Lutheran preachers also did their share in stirring up high and low against the burden of taxes imposed by the wars. Hence it was quite commonly alleged against the instigator of the religious innovations that, mainly owing to his action after the Diet of Spires, there was a general reluctance to grant the necessary supplies, though the clouds on the eastern horizon of the Empire were growing ever blacker. After the horrible disaster at Mohacz, in 1526, Luther therefore found it necessary to exculpate himself before the public.
In Favour of Assistance for the Turkish War.
Luther gradually arrived at the decision that it was his duty to put his pen at the service of the war against the Turks.
A change took place in his attitude similar to that which had occurred in 1525 at the time of the Peasant Rising, which his words, and those of the Reformed preachers, had done not a little to further.
His friends, he says in 1529, “because the Turk was now so near,” had insisted on his finishing a writing against them which had already been commenced; “more particularly because of some unskilful preachers among us Germans, who, I regret to learn, are teaching the people that they must not fight against the Turks.” Some, he writes, also taught, that “it was not becoming for any Christian to wield the sword”; others went so far as to look forward to the coming of the Turks and their rule. “And such error and malice amongst the people is all placed at Luther’s door, as the fruit of my Evangel; in the same way that I had to bear the blame of the revolt [of the peasants].... Hence I am under the necessity of writing on the matter and of exculpating us, both for my own sake and for that of the Evangel ... in order that innocent consciences may not continue to be deceived by such calumnies, and be rendered suspicious of me and my teaching, or be wrongly led to believe that they must not fight against the Turks.”[205]
In February, 1528, Suleiman II. was in a position to demand that King Ferdinand should evacuate Buda-Pesth, the capital; it was already feared that his threat of visiting Ferdinand in Austria might be all too speedily fulfilled. The Sultan actually commenced, in the spring of 1529, his great campaign, which brought him to the very walls of Vienna. The city, however, defended itself with such heroism that the enemy was at last compelled to withdraw.
In April, 1529, when the reports of the danger which menaced Austria had penetrated throughout the length and breadth of Germany, Luther at last published the writing above referred to, viz. “On the Turkish War.”
The booklet he dedicated to that zealous patron of the Reformation, Landgrave Philip of Hesse. In it his intention is to teach “how to fight with a good conscience.” He points out how the Emperor, as a secular ruler, must, agreeably with the office conferred on him by God, protect his subjects against the Turks, as against murderers and robbers, with the secular sword, which, however, has nothing to do with the faith. There were two who must wage the war, Christian and Charles; but Christian’s duty was merely that of the faithful everywhere who would pray for the success of the campaign; this was all that the believers, as such, had to do; Charles would fight, because the example of Charles the Great would encourage him to bear the sword bravely, but only against the Turks as robbers and disturbers of the peace; it would be no Crusade, such as had been undertaken against the infidel in the foolish days of old. Amongst the most powerful pages of the work are those in which, regardless of flattery, he impresses on the German Princes the need of union, of sacrifice of private interests and of obedience to the guidance of the Emperor, without which it was useless to hope for anything in the present critical condition of the Empire. He scourges with a like severity certain faults into which Germans were prone to fall when engaged in warfare, viz. to under-estimate the strength of the enemy, and to neglect following up their victories; instead of this, they would sit down and tipple until they again found themselves in straits.[206]
