Luther's friends at Augsburg, and Staupitz, who had just arrived there, now attempted to divert the course of these proceedings, to collect other decisions of importance bearing on the subject, and to give him the opportunity of a public vindication. Accompanied therefore by several jurists friendly to his cause, and by a notary and Staupitz, he laid before the legate next day a short and formal statement of defence. He could not retract unless convicted of error, and to all that he had said he must hold as being Catholic truth. Nevertheless he was only human, and therefore fallible, and he was willing to submit to a legitimate decision of the Church. He offered, at the same time, publicly to justify his theses, and he was ready to hear the judgment of the learned doctors of Basle, Freiburg, Louvain, and even Paris upon them. Caietan with a smile dismissed Luther and his proposals, but consented to receive a more detailed reply in writing to the principal points discussed on the previous day. On the morrow, October 14, 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. He spoke with crucial emphasis of the trouble he had taken to interpret the words of Pope Clement in a Scriptural sense. The Papal decrees might err, and be at variance with Holy Writ. Even the Apostle Peter himself had once to be reproved (Galat. ii. 11 sqq.) for 'walking not uprightly according to the truth of the gospel;' surely then his successor was not infallible. Every faithful believer in Christ was superior to the Pope, if he could show better proofs and grounds of his belief. Still he entreated Caietan 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. Caietan, to whom he delivered this reply in person, once more tried to persuade him. They fell into a lively and vehement argument; but Caietan 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.'
