Luther still continued to preach daily, and declared that he was still a Catholic and that as Popes had made mistakes before, so had Pope Leo erred this time. With the Bull came a notice that, if Luther would recant, the Bull would be withdrawn and Luther would be reinstated in the Church. To which Luther replied, "If the Bull is withdrawn I will still be in the Church." Bonfires of Luther's books now burned bright in every town and city of Christendom--even in London. Then it was that Wittenberg decided to have a bonfire of its own. A printed bill was issued calling upon all students and other devout Christians to assemble at nine o'clock on the morning of December Tenth, Fifteen Hundred Twenty, outside the Elster gate, and witness a pious and religious spectacle. A large concourse gathered, a pyre of fagots was piled high, the Pope's Bull of Excommunication was solemnly placed on top, and the fire was lighted by the hand of Martin Luther. * * * * * The Theses prepared by Tetzel had small sale. People had heard all these arguments before, but Luther's propositions were new. Everything that Luther said in public now was taken down, printed and passed along; his books were sold in the marketplaces and at the fairs throughout the Empire. Luther glorified Germany, and referred often to the "Deutsche Theologie," and this pleased the people. The jealousy that existed between Italians and Germans was fanned. He occasionally preached in neighboring cities, and always was attended by an escort of several hundred students. Once he spoke at Nuremberg and was entertained by that great man and artist, Albert Durer. Everywhere crowds hung upon his words, and often he was cheered and applauded, even in churches. He denounced the extravagance and folly of ecclesiastical display, the wrong of robbing the poor in order to add to the splendor of Rome; he pleaded for the right of private interpretation of the Scriptures, and argued the need of repentance and a deep personal righteousness. Not only was Luther the most popular preacher of that day, but his books outsold all other authors. He gave his writings to whoever would print them, and asked for no copyright nor royalties. A request came from the Pope that he should appear at Rome. Such a summons is considered mandatory, and usually this letter, although expressed in the gentlest and most complimentary way, strikes terror to the heart of the receiver. It means that he has offended or grieved the Head of the Church--God's Vicegerent on earth. In my own experience I have known several offending priests to receive this summons; I never knew of one who dared disregard the summons; I never knew of one who received it who was not filled with dire foreboding; and I never knew an instance where the man was humiliated or really punished.
