These prayers were not in vain. The warnings which the Elector had given Rome, through his envoy, were not without foundation. The word of Luther had been every where heard, in cottages, and convents, at the firesides of the citizens, in the castles of nobles, in academies, and in the palaces of kings. He had said to Duke John of Saxony, "Let my life only have contributed to the salvation of a single individual, and I will willingly consent that all my books perish."[188] Not a single individual, but a great multitude, had found light in the writings of the humble doctor; and hence, in all quarters, there were men ready to protect him. The sword which was to attack him was on the anvil of the Vatican; but there were heroes in Germany who would interpose their bodies as his buckler. At the moment when the bishops were waxing wroth, when princes were silent, when the people were awaiting the result, and when the thunder was already grumbling on the seven hills, God raised up the German nobility, and placed them as a rampart around his servant.

At this time Sylvester of Schaumburg, one of the most powerful nobles of Franconia, sent his son to Wittemberg with a letter for the Reformer, in which he said, "Your life is exposed to danger. If the support of electors, princes, or magistrates fails you, I beg you to beware of going into Bohemia, where, of old, very learned men had much to suffer; come rather to me; God willing, I shall soon have collected more than a hundred gentlemen, and with their help, will be able to keep you free from harm."[189] [189] "Denn Ich, und hundert von Adel, die Ich (ob Gott will) aufbringen will, euch redlich anhalten".... (L. Op. (L.) xvii, p. 381.) [Sidenote: LUTHER'S CONFIDENCE.]
