Next day (April 19th) the Emperor proposed that Luther should be placed under the ban of the Empire. The Estates were not satisfied, and insisted that something should be done to effect a compromise. Luther had not been treated as they had proposed in their memorandum of the 19th February. He had been peremptorily ordered to retract. The Emperor had permitted Aleander to regulate the order of procedure on the day previous (April 18th), and the result had not been satisfactory. Even the Elector of Brandenburg and his brother, the hesitating Archbishop of Mainz, did not wish matters to remain as they were. They knew the feelings of the German people, if they were ignorant of the Emperor’s diplomatic dealings with the Pope. The Emperor gave way, but told them that he would let them hear his own view of the matter. He produced a sheet of paper, and read a short statement prepared by himself in the French tongue—the language with which Charles was most familiar. It was the memorable declaration of his own religious position, which has been referred to already.(285) Aleander reports that several of the princes became pale as death when they heard it.(286) In later discussions the Emperor asserted with warmth that he would never change one iota of his declaration. Nevertheless, the Diet appointed a Commission (April 22nd) to confer with Luther, and at its head was placed the Archbishop of Trier, who was perhaps the only one among the higher ecclesiastics of Germany whom Luther thoroughly trusted. They had several meetings with the Reformer, the first being on the 24th of April. All the members of the Commission were sincerely anxious to arrange a compromise; but after the Emperor’s declaration that was impossible, as Luther himself clearly saw. No set of resolutions, however skilfully framed, could reconcile the Emperor’s belief that a General Council was infallible and Luther’s phrase, “a conscience bound to the Holy Scriptures.” No proposals to leave the final decision to the Emperor and the Pope, to the Emperor alone, to the Emperor and the Estates, to a future General Council (all of which were made), could patch up a compromise between two such contradictory standpoints. Compromise must fail in a fight of faiths, and that was the nature of the opposition between Charles V. and Luther throughout their lives. What divided them was no subordinate question about doctrine or ritual; it was fundamental, amounting to an entirely different conception of the whole round of religion. The moral authority of the individual conscience confronted the legal authority of an ecclesiastical assembly. In after days the monk regretted that he had not spoken out more boldly before the Diet. Shortly before his death, the Emperor expressed his regret that he had not burned the obstinate heretic. When the Commission had failed, Luther asked leave to reveal his whole innermost thoughts to the Archbishop of Trier, under the seal of confession, and the two had a
