After his return from Rome, Luther received at the University of Wittenberg the degree of doctor of divinity. Now he was at liberty to devote himself, as never before, to the Scriptures that he loved. He had taken a solemn vow to study carefully and to preach with fidelity the word of God, not the sayings and doctrines of the popes, all the days of his life. He was no longer the mere monk or professor, but the authorized herald of the Bible. He had been called as a shepherd to feed the flock of God, that were hungering and thirsting for the truth. He firmly declared that Christians should receive no other doctrines than those which rest on the authority of the Sacred Scriptures. These words struck at the very foundation of papal supremacy. They contained the vital principle of the Reformation.
Luther saw the danger of exalting human theories above the word of God. He fearlessly attacked the speculative infidelity of the schoolmen and opposed the philosophy and theology which had so long held a controlling influence upon the people. He denounced such studies as not only worthless but pernicious, and sought to turn the minds of his hearers from the sophistries of philosophers and theologians to the eternal truths set forth by prophets and apostles.
Precious was the message which he bore to the eager crowds that hung upon his words. Never before had such teachings fallen upon their ears. The glad tidings of a Saviour's love, the assurance of pardon and peace through His atoning blood, rejoiced their hearts and inspired within them an immortal hope. At Wittenberg a light was kindled whose rays should extend to the uttermost parts of the earth, and which was to increase in brightness to the close of time.
But light and darkness cannot harmonize. Between truth and error there is an irrepressible conflict. To uphold and defend the one is to attack and overthrow the other. Our Saviour Himself declared: "I came not to send peace, but a sword." Matthew 10:34. Said Luther, a few years after the opening of the Reformation: "God does not guide me, He pushes me forward. He carries me away. I am not master of myself. I desire to live in repose; but I am thrown into the midst of tumults and revolutions."--D'Aubigne, b. 5, ch. 2. He was now about to be urged into the contest.
The Roman Church had made merchandise of the grace of God. The tables of the money-changers (Matthew 21:12) were set up beside her altars, and the air resounded with the shouts of buyers and sellers. Under the plea of raising funds for the erection of St. Peter's Church at Rome, indulgences for sin were publicly offered for sale by the authority of the pope. By the price of crime a temple was to be built up for God's worship--the cornerstone laid with the wages of iniquity! But the very means adopted for Rome's aggrandizement provoked the deadliest blow to her power and greatness. It was this that aroused the most determined and successful of the enemies of popery, and led to the battle which shook the papal throne and jostled the triple crown upon the pontiff's head.
The official appointed to conduct the sale of indulgences in Germany--Tetzel by name--had been convicted of the basest offenses against society and against the law of God; but having escaped the punishment due for his crimes, he was employed to further the mercenary and unscrupulous projects of the pope. With great effrontery he repeated the most glaring falsehoods and related marvelous tales to deceive an ignorant, credulous, and superstitious people. Had they possessed the word of God they would not have been thus deceived. It was to keep them under the control of the papacy, in order to swell the power and wealth of her ambitious leaders, that the Bible had been withheld from them. (See John C. L. Gieseler, A Compendium of Ecclesiastical History, per. 4, sec. 1, par. 5.)As Tetzel entered a town, a messenger went before him, announcing: "The grace of God and of the holy father is at your gates."--D'Aubigne, b. 3, ch.
1. And the people welcomed the blasphemous pretender as if he were God Himself come down from heaven to them. The infamous traffic was set up in the church, and Tetzel, ascending the pulpit, extolled the indulgences as the most precious gift of God. He declared that by virtue of his certificates of pardon all the sins which the purchaser should afterward desire to commit would be forgiven him, and that "not even repentance is necessary."--Ibid., b. 3, ch. 1. More than this, he assured his hearers that the indulgences had power to save not only the living but the dead; that the very moment the money should clink against the bottom of his chest, the soul in whose behalf it had been paid would escape from purgatory and make its way to heaven. (See K. R. Hagenbach, History of the Reformation, vol. 1, p. 96.)When Simon Magus offered to purchase of the apostles the power to work miracles, Peter answered him: "Thy money perish with thee, because thou hast thought that the gift of God may be purchased with money." Acts 8:20. But Tetzel's offer was grasped by eager thousands. Gold and silver flowed into his treasury. A salvation that could be bought with money was more easily obtained than that which requires repentance, faith, and diligent effort to resist and overcome sin. (See Appendix note for page 59.)The doctrine of indulgences had been opposed by men of learning and piety in the Roman Church, and there were many who had no faith in pretensions so contrary to both reason and revelation. No prelate dared lift his voice against this iniquitous traffic; but the minds of men were becoming disturbed and uneasy, and many eagerly inquired if God would not work through some instrumentality for the purification of His church.
