On the morrow, October 14th, Luther brought his reply to the legate. But in this document also he insisted clearly and resolutely from the commencement on those very principles which his opponents regarded as destructive of all ecclesiastical authority and of the foundations of Christian belief. Still he entreated Cajetan to intercede with Leo X, that the latter might not harshly thrust out into darkness his soul, which was seeking for the light. But he repeated that he could do nothing against his conscience: one must obey God rather than man, and he had the fullest confidence that he had Scripture on his side. Cajetan, to whom he delivered this reply in person, once more tried to persuade him. They fell into a lively and vehement argument; but Cajetan cut it short with the exclamation, "Revoke." In the event of Luther not revoking or submitting to judgment at Rome, he threatened him and all his friends with excommunication, and whatever place he might go to with an interdict; he had a mandate from the Pope to that effect already in his hands. He then dismissed him with the words, "Revoke, or do not come again into my presence." Nevertheless he spoke in quite a friendly manner after this to Staupitz, urging him to try his best to convert Luther, whom he wished well. Luther, however, wrote the same day to his friend Spalatin, who was with the Elector, and to his friends at Wittenberg, telling them he had refused to yield. Luther added further that an appeal would be drawn up for him in the form best fitted to the occasion. He further hinted to his Wittenberg friends at the possibility of his having to go elsewhere in exile; indeed, his friends already thought of taking him to Paris, where the university still rejected the doctrine of papal absolutism. He concluded this letter by saying that he refused to become a heretic by denying that which had made him a Christian; sooner than do that, he would be burned, exiled, or cursed. The appeal, of which Luther here spoke, was "from the Pope ill-informed to the same when better informed." On October 16th he submitted it, formally prepared, to a public notary. Luther even addressed, on October 17th, a letter to Cajetan, conceding to him the utmost he thought possible. Moved, as he said, by the persuasions of his dear father Staupitz and his brother Link, he offered to let the whole question of indulgences rest, if only that which drove him to this tragedy were put a stop to; he confessed also to having been too violent and disrespectful in dispute. In after-years he said to his friends, when referring to this concession, that God had never allowed him to sink deeper than when he had yielded so much. The next day, however, he gave notice of his appeal to the legate, and told him he did not wish longer to waste his time in Augsburg. To this letter he received no answer.
