Luther, however, lost no time in following up their execution of the bull with his reply. On December 10th he posted a public announcement that the next morning, at nine o'clock, the anti-Christian decretals, that is, the papal law-books, would be burned, and he invited all the Wittenberg students to attend. He chose for this purpose a spot in front of the Elster gate, to the east of the town, near the Augustinian convent. A multitude poured forth to the scene. With Luther appeared a number of other doctors and masters, and among them Melanchthon and Carlstadt. After one of the masters of art had built up a pile, Luther laid the decretals upon it, and the former applied the fire. Luther then threw the papal bull into the flames, with the words, "Because thou hast vexed the Holy One of the Lord,[28] let the everlasting fire consume thee." While Luther with the other teachers returned to the town, some hundreds of students remained upon the scene and sang a _Te Deum_, and a Dirge for the decretals. After the ten o'clock meal, some of the young students, grotesquely attired, drove through the town in a large carriage, with a banner, emblazoned with a bull, four yards in length, amid the blowing of brass trumpets and other absurdities. They collected from all quarters a mass of scholastic and papal writings, and hastened with them and the bull to the pile, which their companions had meanwhile kept alight. Another _Te Deum_ was then sung, with a requiem, and the hymn, "_O du armer Judas_." Luther at his lecture the next day told his hearers with great earnestness and emotion what he had done. The papal chair, he said, would yet have to be burned. Unless with all their hearts they abjured the kingdom of the pope, they could not obtain salvation. By this bold act, Luther consummated his final rupture with the papal system, which for centuries had dominated the Christian world and had identified itself with Christianity. The news of it must also have made the fire which his words had kindled throughout Germany blaze out in all its violence. He saw now, as he wrote to Staupitz, a storm raging, such as only the last day could allay, so fiercely were passions aroused on both sides. Germany was then, in fact, in a state of excitement and tension more critical than at any other period of her history. The announcement of the retractation required from Luther by the bull was to have been sent to Rome within one hundred twenty days. Luther had given his answer. The Pope declared that the time of grace had expired; and on January 3d Leo X finally pronounced the ban against Luther and his followers, and an interdict on the places where they were harbored.
