The supreme interest of these rambling streets are the associations with the great Protestant reformer. Wittenberg is a place of pious pilgrimage for those who revere the memory of Luther and Melanchthon. The Schloss Kirche contains the ashes of the two preachers of the reformed faith; and it was on the door of this church that Luther nailed his bold indictment of papal corruption. The town abounds with memories of that stupendous battle for religious liberty which spread into all parts of Christendom. How vast were the issues in the balance when Martin Luther defied the power of Rome! Long before the theologian of Wittenberg, several reformers had uttered protests against the sale of indulgences by the Church of Rome. Huss, Jerome of Prague, John of Wessel, John of Goch, all raised their fervent voices upon the evils of the system. The Bible was now coming into the hands of the laity; Wicliff's versions were in use in England, and in Germany, Reuchlin and others had made Hebrew the study of the educated. Erasmus, too, had satirised the vicious lives of the monks. The way was prepared for a popular reformer, such as the ardent priest and theologian of Wittenberg. Archbishop Albert of Mayence and Magdeburg was indebted to Pope Leo X. for his investiture, and was unable to raise the money. The Pope was in need of funds. He therefore gave permission to the archbishop to establish a wide sale of indulgences in Germany. The bulk of the people, reared in obedience to Rome, made no complaint of the practice, and were quite ready to purchase absolution for their sins. But Luther contended that indulgences only brought the remission of penalties, and refused to offer complete pardon for indulgences alone. Tetzel, the agent of Leo X., was naturally enraged. He thundered anathemas upon the presumptuous Luther. The reformer met his denunciations by affixing his defiant propositions to the door of the Schloss Kirche. So began the historic struggle between Catholics and Protestants. Luther merely impeached the sale of indulgences; he was still loyal to the papal authority. The Pope was, however, headstrong and tyrannous. He showed neither tact nor diplomacy, but issued a bill of excommunication against the unruly priest. The document was burned in contempt by Martin Luther. Let us glance at the character of this doughty heretic. The birthplace of Luther was Eisleben, in Saxony, and he was born in 1483. His first school was at Magdeburg, and he was educated for the law. But the early trend of his mind was pietistic; he aspired to become a teacher of religion. He joined the Augustine Order, and observed devoutly all the canons of the Catholic creed. We read that Luther was appointed professor at the University of Wittenberg; that he taught many students, and discoursed eloquently.
