Luther followed the advice of his friends at Nuremberg. The specific evil he had denounced was now admitted by the authorised representative of the Holy See. He obtained, through him, a reassuring glimpse of Roman opinion, and the certainty that there were men on the spot, unlike Prierias and Cajetan, whose convictions in regard to unreformed abuses were as clear as his own, and whose opportunities were better. They came to an understanding. Luther was to publish an explanation and then the subject was to drop. It did not mean that he was approved; but dubious points were not pressed, for the sake of those on which the force of his case was felt. He wrote to a friend that he would suppress much rather than offend, and the whole thing would die out of itself. The contrast between Miltitz and Cajetan was such that he had reason to be satisfied. Miltitz also considered that he had done well, and had extinguished a conflagration that might have become serious. He advised the Elector not to send the Wittenberg professor out of the country. More eager spirits were impatient of so tame a conclusion; for there were some to whom plenary indulgences for the living or the dead were a drop of water in an ocean of controversy, whilst others thought that authority had been outraged on one side and surrendered on the other. Before the dispute was reopened Luther wrote a letter to Leo X, saying the ecclesiastical authority must be upheld to the utmost. This saying, of little account in his theology, is significant in his entire system of thought. What he meant was that the papal supremacy in the government of the Church had endured so long that the divine sanction was upon it. He did not trace it much farther back than the twelfth century. But that, he considered, constituted a legitimate claim.
