Melanchthon thus openly expresses himself in regard to his position at that time, and we are warranted in believing that these were the honest and sincere sentiments of his heart. But still more difficult relations arose, in which his Christian character was to be tried in the severest manner. The following chapters will show how he demeaned himself in these.
The Emperor Charles, proud of his victories, would not be satisfied until he also succeeded in securing the second leader of the League of Smalkald, the Landgrave Philip of Hesse. For this purpose he also employed Duke Maurice, which was especially disgraceful, because he was the son-in-law of the Landgrave. Maurice did not believe that the Emperor would capture the Landgrave treacherously, in order to lead him behind his victorious chariot, as he did with Duke John Frederick. The Landgrave yielded to persuasion, and upon his knees asked the Emperor's pardon; yet, notwithstanding all assurances to the contrary, he was seized and made a close prisoner. Thus the League of Smalkald was destroyed, and the Emperor found himself the mighty monarch of all he surveyed.
In the meantime, the Council of Trent had published several articles of religion, which were opposed to the acknowledged Evangelical truth; and the Pope had now also removed it from Trent to Italian soil, to Bologna, in order to have it completely in his power. This displeased the Emperor, who did not like to see the Pope assuming too powerful and prominent a position. On the 1st September, 1547, he had opened another diet at Augsburg, towards which many looked with great anxiety. Not only the Ecclesiastical Electors, but also the Protestant princes were induced, by his influence, to declare that they would submit to the Council, provided it should be removed back again to Trent, and the articles of religion would be reconsidered. John Frederick alone opposed this; while the Pope did the same on the other side, because he could not bear to see the growing power of the Emperor. But Charles had for years learned at least so much, that it would be utterly impossible to introduce into Germany a reformation such as the Papacy desired; and because he wished to hold all the reins, not only of the worldly, but also of the spiritual government, in his own hands, he proposed to undertake the Reformation of the German Church himself. He had entertained this project for a long time, as he also manifested by the Ratisbon book, and now he believed he could carry out his plans, almost without any opposition, as the German States were prostrate at his feet. He therefore proposed to these to appoint a number of able men to meet and deliberate for the present, upon a form of doctrine and discipline for the Church. In January, 1548, Duke Maurice had demanded the opinion of the Theologians of Wittenberg, in regard to this matter. On the 26th of January, they replied: "We see that it is intended to form an interim, which many States, who are now one with us in doctrine, will not receive, which will cause new and great wars. Therefore, we need the Grace of God and good counsel in this matter, which we dread very much. It would be burdensome besides, to afflict our Churches by new changes; and it would be Christian and beneficial to suffer them to remain in their present condition." As the Elector had summoned them to Augsburg, they declared they would hold themselves in readiness. In regard to the Council, which was to be continued in Trent, Melanchthon expressed himself to the following purpose: "I believe, that if we agree to holding it, we are also bound to obey its decrees. But as various articles are false and opposed to divine truth, I cannot advise their adoption, and thus burden my conscience. But if the Emperor should insist upon a General Council, the other side should also be heard. The Emperor should be urged to permit an accommodation in Germany, as had been advised in Spire. And both sides should present written opinions."
