Martin Luther was a German monk, priest, professor, biblical translator, and reformer whose challenge to late-medieval church teaching helped initiate the Protestant Reformation. His emphasis on the authority of Scripture, justification by faith, and the grace of God permanently reshaped Western Christianity.

Luther was born on November 10, 1483, in Eisleben, within the Holy Roman Empire. His father, Hans Luther, worked in mining and hoped that his son would enter the legal profession. Luther studied at the University of Erfurt and began training in law. In 1505, however, after being caught in a severe thunderstorm and fearing death, he vowed to become a monk. He entered the Augustinian monastery in Erfurt and was ordained as a priest in 1507.

Luther pursued the monastic life with great seriousness, yet he remained troubled by his awareness of sin and his fear of divine judgment. His study of Scripture, especially the Psalms, Galatians, and Romans, gradually transformed his understanding of righteousness. Luther came to believe that sinners are justified before God not by accumulating merit or performing prescribed religious works, but through faith in Jesus Christ. Even this faith is not a human achievement; it receives the righteousness God freely gives through the gospel.

In 1512 Luther became a doctor of theology and professor of biblical studies at the University of Wittenberg. His public controversy began in 1517 when he circulated the Ninety-Five Theses, challenging abuses connected with the sale of indulgences. The theses questioned whether church authorities could promise release from divine punishment in exchange for payments and insisted that the true treasure of the church is the gospel of God’s grace.

The controversy soon expanded beyond indulgences. Luther questioned papal authority, defended the supremacy of Scripture, and rejected teachings he believed lacked biblical foundation. He was excommunicated in 1521 and summoned before Emperor Charles V at the Diet of Worms. When pressed to withdraw his writings, Luther refused unless convinced by Scripture and sound reasoning. He was subsequently declared an outlaw. Frederick the Wise protected him at Wartburg Castle, where Luther translated the New Testament into vigorous, accessible German. His complete German Bible later exerted enormous influence on worship, literacy, and the development of the German language.

Luther returned to Wittenberg and continued preaching, teaching, writing, and organizing reform. In 1525 he married Katharina von Bora, a former nun. Their household became a center of family life, theological discussion, hospitality, and education. Luther also wrote catechisms, hymns, sermons, biblical commentaries, and major theological works, including The Freedom of a Christian and The Bondage of the Will.

Luther’s legacy requires honest evaluation. During the Peasants’ War, he condemned the violent uprising in harsh language and supported its suppression. His later writings against Jewish people were vicious and indefensible, advocating measures that Christians must unequivocally reject. These writings contradict the command to love one’s neighbor and have cast a lasting shadow over his legacy.

As a conversation partner, Luther is especially valuable for his insistence that Christ and the gospel stand at the center of Scripture. He reminds readers that salvation is received by grace through faith and cannot be earned. Yet Luther himself must be examined by the same standard he championed: every teacher and every teaching must be tested by the Word of God.
