Martin Luther

Martin Luther was born on November 10, 1483, in Eisleben, Saxony. After studying law at Erfurt, he entered an Augustinian monastery in 1505 following a dramatic vow during a thunderstorm. Ordained in 1507, he earned his doctorate in theology in 1512 and was appointed professor of biblical studies at the University of Wittenberg.

During intensive study of Romans and the Psalms, Luther arrived at his breakthrough understanding of justification as God's gift received by faith rather than earned by human effort. In 1517, troubled by Johann Tetzel's sale of indulgences, he composed his Ninety-Five Theses for academic debate. Their rapid printing and distribution ignited a controversy that escalated beyond Luther's initial intentions. His three great treatises of 1520 — Address to the Christian Nobility, The Babylonian Captivity of the Church, and On the Freedom of a Christian — articulated a comprehensive reform program. Excommunicated in 1521, he refused to recant at the Diet of Worms. Protected by Frederick the Wise at Wartburg Castle, he began translating the Bible into German.

Luther's literary output was extraordinary: biblical commentaries, catechisms, polemical works, sermons, letters, and approximately thirty-six hymns including 'A Mighty Fortress Is Our God.' He married Katharina von Bora in 1525. His Table Talk, recorded by students, reveals the breadth of his thought. His later writings include virulently anti-Jewish works, particularly On the Jews and Their Lies (1543), which have been rightly repudiated by Lutheran churches worldwide. He died on February 18, 1546, in Eisleben.
