Meanwhile what was the attitude of the authorities in Rome towards Luther's movement. Leo X., having learned something of the turmoil created in Germany by Luther's theses and sermons, requested the vicar-general of the Augustinians to induce his rebellious subject to recall his teaching, or, at least, to keep silent. The vicar wrote to the principal, Staupitz, but, as the latter was one of those who had encouraged Luther to take the steps he had taken, very little was done to secure peace. Luther was, however, induced to write a most submissive letter to the Pope in which he begged for an investigation, pledging himself at the same time to accept the decision of Leo X. as the decision of Christ (30th May, 1518).[14] Not satisfied with the course of events, and alarmed by the reports forwarded to him from Germany, the Pope appointed a commission to examine the whole question, the result of which commission was that Luther was summoned to submit at once or to appear at Rome to defend himself within sixty days. He and his friends were thrown into a state of great alarm by this unexpected step. On the one hand, were he to submit and to acknowledge that he had been in error his reputation would be shattered, the Augustinians would feel themselves disgraced, and the University of Wittenberg would lose caste in the estimation of educated Germans. On the other hand, if he adopted the bold policy of refusing to yield to the papal entreaties he was in danger of being denounced publicly as a heretic. In this difficult situation his friends determined to invoke the protection of the Elector Frederick of Saxony, the founder and patron of Wittenberg University. Alarmed by the danger that threatened this institution from the removal or excommunication of one of its most popular professors, and anxious to gain time, Frederick requested the Pope to refer the matter for decision to some German bishop or to a neutral university. In reply to this request Leo X. appointed Cardinal Cajetan, papal legate in Germany, to hold an inquiry (23 Aug., 1518). Luther, having armed himself with a safe conduct, went to Augsburg to meet the papal representative, who received him very kindly, and exhorted him to withdraw his statements and submit. Luther endeavoured to induce the cardinal to enter into a discussion on the questions in dispute, but the latter did not allow himself to be drawn into a disputation. Finally, Luther refused to submit, though, at the same time, he declared solemnly that he wished unsaid and unwritten what he had said or written against the Roman Church. A few days later he fled from Augsburg after having drawn up a formal appeal "from the Pope ill-informed to the Pope well-informed," while the cardinal, disappointed by the failure of his efforts, turned to the Elector of Saxony for help against the rebellious monk. But the latter, deceived by the recommendations forwarded on Luther's behalf by his own
