The next move of the Vicar of Christ was to send to Germany a special agent, the Saxon Charles von Miltitz, with instructions either to cajole the heretic into retraction or the Elector into surrendering him. In neither of these attempts was he successful. [Sidenote: January 1519] At an interview with Luther the utmost he could do was to secure a general statement that the accused man would abide by the decision of the Holy See, and a promise to keep quiet as long as his opponents did the same.
Such a compromise was sure to be fruitless, for the champions of the church could not let the heretic rest for a moment. The whole affair was given a wider publicity than it had hitherto attained, and at the same time Luther was pushed to a more advanced position than he had yet reached, by the attack of a theologian of Ingolstadt, John Eck. When he assailed the Theses on the ground that they seriously impaired the authority of the Roman see, Luther retorted:
{69} The assertion that the Roman Church is superior to all other churches is proved only by weak and vain papal decrees of the last four hundred years, and is repugnant to the accredited history of the previous eleven hundred years, to the Bible, and to the decree of the holiest of all councils, the Nicene.
[Sidenote: The Leipzig Debate, 1519]
A debate on this and other propositions between Eck on the one side and Luther and his colleague Carlstadt on the other took place at Leipzig in the days from June 27 to July 16, 1519. The climax of the argument on the power of popes and councils came when Eck, skilfully manoeuvring to show that Luther's opinions were identical with those of Huss, forced from his opponent the bold declaration that "among the opinions of John Huss and the Bohemians many are certainly most Christian and evangelic, and cannot be condemned by the universal church." The words sent a thrill through the audience and throughout Christendom. Eck could only reply: "If you believe that a general council, legitimately convoked, can err, you are to me a heathen and a publican." Reconciliation was indeed no longer possible. When Luther had protested against the abuse of indulgences he did so as a loyal son of the church. Now at last he was forced to raise the standard of revolt, at least against Rome, the recognized head of the church. He had begun by appealing from indulgence-seller to pope, then from the pope to a universal council; now he declared that a great council had erred, and that he would not abide by its decision. The issue was a clear one, though hardly recognized as such by himself, between the religion of authority and the right of private judgment.
His opposition to the papacy developed with extraordinary rapidity. His study of the Canon Law made him, as early as March, 1519, brand the pope as either Antichrist or Antichrist's apostle. He {70} applauded Melancthon, a brilliant young man called to teach at Wittenberg in 1518, for denying transubstantiation. He declared that the cup should never have been withheld from the laity, and that the mass considered as a good work and a sacrifice was an abomination. His eyes were opened to the iniquities of Rome by Valla's exposure of the Donation of Constantine, published by Ulrich von Hutten in 1519. After reading it he wrote:
Good heavens! what darkness and wickedness is at Rome! You wonder at the judgment of God that such unauthentic, crass, impudent lies not only lived but prevailed for many centuries, that they were incorporated into the Canon Law, and (that no degree of horror might be wanting) that they became as articles of faith.
Like German troops Luther was best in taking the offensive. These early years when he was standing almost alone and attacking one abuse after another, were the finest of his whole career. Later, when he came to reconstruct a church, he modified or withdrew much of what he had at first put forward, and re-introduced a large portion of the medieval religiosity which he had once so successfully and fiercely attacked. The year 1520 saw him at the most advanced point he ever attained. It was then that he produced, with marvellous fecundity, a series of pamphlets unequalled by him and unexcelled anywhere, both in the incisive power of their attack on existing institutions and in the popular force of their language.
[Sidenote: To the Christian Nobility, 1520]
His greatest appeal to his countrymen was made in his Address to the Christian Nobility of the German Nation on the Improvement of the Christian Estate. In this he asserts the right of the civil power to reform the spiritual, and urges the government to exercise this right. The priests, says he, defend themselves against all outside interference by three "walls," of {71} which the first is the claim that the church is superior to the state, in case the civil authority presses them; the second, the assertion, if one would correct them by the Bible, that no one can interpret it but the pope; the third, if they are threatened with a general council, the contention that no one can convoke such a council save the pope. Luther demolishes these walls with words of vast import. First, he denies any distinction between the spiritual and temporal estates. Every baptized Christian, he asserts, is a priest, and in this saying he struck a mortal blow at the great hierarchy of privilege and theocratic tyranny built up by the Middle Ages. The second wall is still frailer than the first, says the writer, for anyone can see that in spite of the priests' claims to be masters of the Bible they never learn one word of it their whole life long. The third wall falls of itself, for the Bible plainly commands everyone to punish and correct any wrong-doer, no matter what his station.
