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 called Calvinism, which emphasizes predestination and God’s complete control over human salvation from death and eternal damnation. His ideas drew heavily on Augustine and other earlier Christian thinkers. Many Reformed church groups—such as Continental Reformed, Congregationalist, Presbyterian, Waldensian, Baptist Reformed, Calvinist Methodist, and Reformed Anglican denominations—consider Calvin the primary interpreter of their beliefs and have spread his influence worldwide. Calvin was a fierce polemicist and apologist, often stirring controversy, yet he also maintained warm, supportive correspondence with fellow reformers like Philipp Melanchthon and Heinrich Bullinger. Besides his landmark work *Institutes of the Christian Religion*, he produced commentaries on most books of the Bible, confessional documents, and numerous theological writings. Originally trained as a humanist lawyer, Calvin broke from the Roman Catholic Church around 1530. After violent anti-Protestant riots broke out in France, he fled to Basel, Switzerland, where he published the first edition of the *Institutes* in 1536. That same year, Frenchman William Farel recruited him to help the Reformation in Geneva. Calvin preached regularly there, but the city council resisted their reforms, and both were expelled. At Martin Bucer’s invitation, Calvin moved to Strasbourg, serving as minister to a French refugee congregation. He continued backing Geneva’s reform movement and was invited back in 1541 to lead its church. Upon returning, Calvin introduced new church government and liturgy, despite opposition from powerful local families who tried to limit his authority. During this time, 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 forced out. He spent his remaining 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, daughter of a Cambrai innkeeper, died of unknown causes in his 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. Young Calvin was exceptionally 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 studied Latin under the renowned teacher Mathurin Cordier. After that, he entered the Collège de Montaigu as a philosophy student. Around 1525 or 1526, Gérard pulled Calvin from Montaigu and enrolled him at the University of Orléans to study law. According to biographers Theodore Beza and Nicolas Colladon, Gérard thought law would be more profitable than the priesthood. After quiet study, Calvin entered the University of Bourges in 1529, drawn by 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. However, 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. In his *Commentary on the Book of Psalms*, Calvin described a sudden change of mind brought about by God: “God by a sudden conversion subdued and brought my mind to a teachable frame, which was more hardened in such matters than might have been expected from one at my early period of life.
