Meanwhile Luther was anxious to respond still further to the call of duty against the Turks. Their multitudinous hosts had advanced as far as Vienna, and had severely harassed that city, which, though defended with heroic valour, was but badly fortified. A general assault was made in force while Luther was on his homeward journey. The news stirred him to his inmost soul. He ascribed to it, and to their god, the devil, the violent temptations and anguish of soul from which he was then suffering again. Immediately after his return, he undertook to write a 'War sermon against the Turks.' On October 26 he received the tidings that they were compelled to retreat. This was a 'heavensent miracle' to him. But though his former exhortations and warnings had seemed to many exaggerated, he was right in perceiving that the danger was only averted. He published his sermon, a new edition of which had to be issued with the new year. He saw in the Turks the fulfilment of the prophecy of Ezekiel and the Revelation of St. John about Gog and Magog, and therewith a judgment of God for the punishment of corrupt Christendom. But just as in his first pamphlet he had called on the authorities, in virtue of their appointment by God, to protect their own people against the enemy, so he now wished further to make all German Christians strong in conscience and full of courage, to take the field under their banner, according to God's command. He set before them the example of the 'beloved St. Maurice and his companions,' and of many other saints, who had served in arms their Emperor as knights or citizens. He would, if danger came in earnest, 'fain have, whoever could, defend themselves,--young and old, husband and wife, man-servant and maid-servant,' just as, according to ancient Roman writers, the German wives and maidens fought together with the men. He looked on no house as so mean that it might not do something to repel the foe. Was it not better to be slain at home, in obedience to God, than to be taken prisoners and dragged away like cattle to be sold? At the same time he exhorted and encouraged those whom this misfortune befell, that, as Jeremiah admonished the Jews in Babylon, they should be patient in prison, and cling firmly to the faith, and neither through their misery nor through the hypocritical worship of the Turks, allow themselves to be seduced into becoming renegades.
