The plan to entrap Melanchthon and some considerable portion of the German Protestants into conciliatory proposals which Luther and the more decided reformers could not admit, having failed through the abrupt and tolerably rude refusal of the Elector of Saxony to permit his theological professor to comply with the invitation of Francis, the latter appears to have determined to put the best appearance upon the affair. Accordingly, he promptly signified to the Sorbonne his approval of its action, and he seems even to have suffered the rumor to gain currency that he was himself dissuaded from bringing Melanchthon to France, by the skilful arguments of the Cardinal of Tournon.[378] In spite of the rebuff he had received, however, Francis made an attempt to effect such an arrangement with the Protestant princes of Germany as would secure their co-operation in his ambitious projects against Charles the Fifth. To compass this end he was quite willing to make concessions to the Lutherans as extensive as those which Melanchthon had offered the Roman Catholics. [Sidenote: Du Bellay's representations at Smalcald.] Four months had not elapsed since the unsuccessful issue of his first mission, before Du Bellay was again in Germany. On the nineteenth of December, he presented himself to the congress of Protestant princes at Smalcald. Much of his address was devoted to a vindication of his master from the charge of cruelty to persons of the same religious faith as that of the hearers. The envoy insisted that the Germans had been misinformed: If Francis had executed some of his subjects, he had not thereby injured the Protestants. The culprits professed very different doctrines. The creed of the Germans had been adopted by common consent. Francis admitted, indeed, that there were some useless and superfluous ceremonies in the church, but could not assent to their indiscriminate abrogation unless by public decree. Ought not the Protestant princes to ascribe to their friend, the French king, motives as pure and satisfactory as those that impelled them to crush the sedition of the peasants and repress the Anabaptists? As for himself, Francis, although mild and humane, both from native temperament and by education, had seen himself compelled, by stern necessity and the dictates of prudence, to check the promptings of his own heart, and assume for a time attributes foreign to his proper disposition. For gladly as he listened to the temperate discussion of any subject, he was justly offended at the presumption of rash innovators, men that refused to submit to the judgment of those whose prerogative it was to decide in such matters as were now under consideration.
