John Calvin

John Calvin (10 July 1509 – 27 May 1564) was a French theologian, pastor, and reformer active in Geneva during the Protestant Reformation. He is best known for shaping the theological system later called Calvinism, which emphasizes predestination and God’s complete control over human salvation from sin and eternal punishment. His ideas drew heavily on earlier Augustinian thought and other Christian traditions. Today, many Reformed church groups—such as Continental Reformed, Congregationalist, Presbyterian, Waldensian, Reformed Baptist, Calvinist Methodist, and Reformed Anglican churches—look to Calvin as their primary theological guide. Calvin was a sharp polemicist and apologist, often stirring controversy, but he also maintained warm, supportive correspondence with reformers like Philipp Melanchthon and Heinrich Bullinger. Besides his major work, *Institutes of the Christian Religion*, he wrote commentaries on most biblical books, confessional documents, and many theological treatises. Originally trained as a humanist lawyer, Calvin broke with the Roman Catholic Church around 1530. After violent anti-Protestant riots in France, he fled to Basel, Switzerland, where he published the first edition of the *Institutes* in 1536. That same year, French reformer William Farel recruited him to help lead the Reformation in Geneva. Calvin preached regularly, but the city council resisted their reforms, and both were expelled. At Martin Bucer’s invitation, Calvin moved to Strasbourg, pastoring a church of French refugees. He kept supporting Geneva’s reform movement, and in 1541 he was invited back to lead the city’s church. Once back, Calvin introduced new church governance and worship practices, despite opposition from powerful local families. During this period, Michael Servetus—a Spaniard considered heretical by both Catholics and Protestants for his views on the Trinity—arrived in Geneva. Calvin denounced him, and the city council had Servetus burned at the stake. After an influx of supportive refugees and new council elections, Calvin’s opponents were pushed out. He spent his final years advancing the Reformation in Geneva and across Europe. **Life**

**Early life (1509–1535)**

John Calvin was born Jehan Cauvin on 10 July 1509 in Noyon, Picardy, France. He was the second of three sons who survived infancy. His mother, Jeanne le Franc, was an innkeeper’s daughter from Cambrai; she died of unknown causes in Calvin’s childhood after bearing four more children. His father, Gérard Cauvin, was a successful cathedral notary and ecclesiastical court registrar who intended all three sons—Charles, Jean, and Antoine—for the priesthood. Calvin was unusually bright. By age 12, he worked as a clerk for the bishop and received the tonsure, symbolizing his dedication to the Church. The influential Montmor family sponsored his education, allowing him to attend the Collège de la Marche in Paris, where he learned Latin from the renowned teacher Mathurin Cordier. After finishing there, he studied philosophy at the Collège de Montaigu. Around 1525 or 1526, his father pulled him out of Montaigu and sent him to the University of Orléans to study law. Biographers Theodore Beza and Nicolas Colladon say Gérard thought law would be more profitable than the priesthood. After a few quiet years, Calvin entered the University of Bourges in 1529, drawn by the humanist lawyer Andreas Alciati. During his 18 months there, he learned Koine Greek, essential for studying the New Testament. The exact date of Calvin’s religious conversion is debated. Some place it around 1533, just before he resigned his chaplaincy, seeing that resignation as direct evidence of his turn to evangelical faith. But T. H. L. Parker argues that while 1533 is a *terminus*, the conversion likely occurred in late 1529 or early 1530. Two different accounts survive.
