Luther had promised to keep silent if his opponents would do the same, and had devoted himself to the study of the Scriptures. John Eck, however, had no such occupation to keep him from controversy, and Luther was not averse to a debate. At the Leipzig disputation, June 27-July 15, 1519, Luther learned more of the logical implications of his position. The plan of Miltitz had failed, but he would not be discouraged. When Miltitz went to Germany, it was under the pretence of a mission "to deliver to his elector the papal golden rose, which the latter had coveted in vain for two years."[1] Now he decided to go in person to Augsburg, where it had been deposited with the Fuggers, and present it to Frederick. This also gave an opportunity for a second meeting with Luther at Liebwierde, October 9, 1519. Luther, although placing little confidence in Miltitz, consented to argue his case before the archbishop of Treves. The plan failed, partly because there was no citation for Luther to appear, partly because the Elector would not allow Luther to go without proper safe-conduct, and partly because Miltitz had not tried to prevent Luther's opponents from challenging him. In spite of the evident lack of confidence on both sides, and in spite of Luther's constant progress in opposition to the Roman Church, Miltitz insisted that "the case is not as black as we priests make it," even when a papal bull was issued against Luther on June 15, 1520. On August 28th Miltitz attended a meeting of the Augustinian monks in Eisleben, and obtained their promise that Luther should be requested to write a letter to the pope assuring him that he had never attacked the pope's person. On September 11th Luther reported to Spalatin what he had done, and said that, although neither he nor his fellow-monks had any confidence in the plan, he would do Miltitz the favor of writing such a letter. This promise seemed meaningless to him after the bull against him had been published. The papal bull had been obtained by Eck, whom Miltitz now considered to be substituted for himself in dealing with Luther, in spite of the authority he had received. That the bull was ignored in some places and despised in others, pleased him and gave him new courage. There might, after all, be some chance for him to make use of his diplomatic skill.
