On the other hand, many of the young theologians studying there enthusiastically accepted his doctrines, and several of them, _e.g._ Martin Bucer of Strassburg (§ 125, 1), John Brenz and Erhard Schnepf of Swabia (§ 133, 3), as well as Theobald Billicanus, afterwards reformer of Nördlingen, etc., there and then consecrated themselves to their life work. § 122.3. =Prierias, Cajetan, and Miltitz, A.D. 1518, 1519.=--Leo X. at first regarded the matter as an insignificant monkish squabble, and praised Brother Martin as a real genius. He gave no heed to Hoogstraten’s outcry of heresy, nor did he encourage the Dominican Prierias in his attack on Luther. The book of Prierias was a harmless affair. Luther gave it a short and crushing reply. Prierias answered in a second and third tract, which Luther simply republished with sarcastic and overwhelming prefaces. The pope then enjoined silence upon his luckless steward. In May, A.D. 1518, Luther wrote a humble epistle to the pope, and added a series of _Resolutiones_ in vindication of his theses. Staupitz is said to have revised both. Meanwhile it had been determined in Rome to deal with the Wittenberg business in earnest. The papal procurator made a complaint against Luther. A court was commissioned, which summoned him to appear in person at Rome to answer for himself. But, on the representations of the University of Wittenberg and the Elector Frederick the Wise, the pope charged Cardinal Cajetan, his legate at the Diet of Augsburg, to take up the consideration of the matter. Luther appeared, and made his appeal to the Bible. The legate however wished him to argue from the schoolmen, demanded an unconditional recantation, and at last haughtily dismissed “the beast with deep eyes and wonderful speculations in his head.” Luther made a formal appeal _a sanctissimo Domino Leone male informato ad melius informandum_, and quitted Augsburg in good spirits. The cardinal now sought to rouse Frederick against the refractory monk, but Luther’s buoyant and humble confidence won the noble elector’s heart. Cajetan continued a vigorous opponent of the reformed doctrine. But Luther’s superiority in Scripture knowledge had so impressed the cardinal, that he now applied himself closely to the study of the Bible in the original tongues; and thus, while firmly attached to the Romish system, he was led on many points, _e.g._ on Scripture and tradition, divorce, injunctions about meats, the use of the vernacular in public worship, the objectionableness of the allegorical interpretation, etc., to adopt more liberal views, so that he was denounced by some Roman Catholic controversialists as guilty of various heresies.--Luther had no reason in any case to look for any good from Rome. Hence he prepared beforehand an appeal for an œcumenical council, which the publisher, against Luther’s will, at once spread abroad.
