His parents were God-fearing people whose piety undoubtedly had an early influence on him. He shared fear of the horrors of hell, purgatory, and the last judgment which was common to people at the close of the middle ages. In the university library he had found a complete Bible and was tremendously impressed with his own ignorance of its contents. He attended church and daily chapel devotions regularly all through school. His introspective nature made him starkly aware of his sins and shortcomings. Life as a monk was held to be the best way to forgiveness and heaven.

Several grim incidents increased his anxiety. While on a holiday from the university he accidentally severed an artery in his leg with his student sword. He almost bled to death and in distress prayed to the Virgin Mary for help. The death of a number of students during a plague moved him profoundly. While returning to Erfurt, following a visit to Mansfeld, he was caught in a heavy thunderstorm and a bolt of lightning struck so close that he was knocked to the ground. Overcome by panic he invoked St. Anna for aid and vowed “Help me, and I will become a monk.” Fifteen days later, on July 17, friends accompanied him to the gate of the “Black Cloister,” monastery of the Order of Augustinian Hermits in Erfurt.

That this decision came later in life than usually was the case, and that his impressionable years had been spent not within the confines of a monastery but in the unrestricted atmosphere of a great university, later proved valuable to him and to the Protestant Church.

Monk and Priest

Luther was not received immediately into the monastery but had to remain for several months in the monastic hostelry examining himself and being examined. In September, 1505, all parties being satisfied, his head was shaved and he was invested with the black Augustinian habit and cowl, and formally received as a novice.

He scrubbed the floors, begged in the streets, and engaged in various ascetic and spiritual exercises. When his probationary year was ended Luther took the vows of obedience, poverty, and chastity and was received into the order of the Augustinian monks. His sincere piety and scholarship so impressed his superiors that he was urged to prepare for the priesthood, and, on April 4, 1507, was ordained to that office.

The petty employments of the monastery did not consume all of Luther’s energy and he devoted himself strenuously to studying the scholastic theology available at that time. However, long hours with books did little to ease his mind and give him the peace of conscience he sought within the cloister walls. The books taught him to rely on his own efforts to procure favor with God, and he was too honest to believe that his penitence was deep enough and his fastings worthy enough to compensate for his sins.

Although his heart was not at rest, Luther continued to perform his priestly duties and undertake any new tasks assigned to him. In the fall of 1508 he was appointed to the chair of moral philosophy which had been entrusted to the Augustinians by the faculty at the newly established University of Wittenberg. Desiring to teach theology rather than logic and ethics, he availed himself of this opportunity to study for a bachelor’s degree which would permit him to lecture on certain books of the Bible. He had virtually completed his studies when he was called back to Erfurt in October, 1509. There he lectured in the monastery for about a year, and in November, 1510, was sent in company with another monk on a mission to Rome.

In the Holy City he visited as many shrines and churches as possible. His high opinion of the papal court was lowered by his observations of its reckless luxury and scandal, but his confidence in the church remained unshaken.
