That he might not be recognised by those who should see him at Wartburg, his ecclesiastic robe was exchanged for the dress of a knight, he wore helmet and sword instead of cassock and cross and let his beard grow freely. Thus changed in appearance, he was known as Junker George (Chevalier George) to those in the castle, and amused himself at times by hunting with his knightly companions in the neighborhood. The greater part of his time, however, was occupied in a difficult literary task, that of translating the Bible into German. The work thus done by him was destined to prove as important in a linguistic as in a theological sense, since it fixed the status of the German language for the later period to the same extent as the English translation of the Bible in the time of James I. aided to fix that of English speech. Leaving Luther, for the present, in his retreat at Wartburg Castle, we must go back in his history and tell the occasion of the events just narrated. No man, before or after his time, ever created so great a disturbance in German thought, and the career of this fugitive monk is one of great historical import. A peasant by birth, the son of a slate-cutter named Hans Luther, he so distinguished himself as a scholar that his father proposed to make him a lawyer, but a dangerous illness, the death of a near friend, and the exhortations of an eloquent preacher, so wrought upon his mind that he resolved instead to become a monk, and after going through the necessary course of study and mental discipline was ordained priest in May, 1507. The next year he was appointed a professor in the university of Wittenberg. There he remained for the next ten years of his life, when an event occurred which was to turn the whole current of his career and give him a prominence in theological history which few other men have ever attained. In 1517 Pope Leo X. authorized an unusually large issue of indulgences, a term which signifies a remission of the temporal punishment due to sin, either in this life or the life to come; the condition being that the recipient shall have made a full confession of his sins and by his penitence and purpose of amendment fitted himself to receive the pardon of God, through the agency of the priest. He was also required to perform some service in the aid of charity or religion, such as the giving of alms. At the time of the Crusades the popes had granted to all who took part in them remission from church penalties. At a later date the same indulgence was granted to penitents who aided the holy wars with money instead of in person. At a still later date remission from the penalties of sin might be obtained by pious work, such as building churches, etc. When the Turks threatened Europe, those who fought against them obtained indulgence. In the instance of the issue of indulgences by Leo X. the pious work required was the giving of alms in aid of the completion of the great cathedral of St. Peter's at Rome.
