See it on the Bible & Christianity map →What it is
Born in Noyon, France, in 1509, Calvin fled persecution and published the Institutes of the Christian Religion in Basel (1536), expanding it until 1559. From 1541 he led Geneva's church, with a consistory of pastors and elders overseeing morals. He stressed God's sovereignty and predestination: God chooses who will be saved. Unlike Luther, he taught a 'spiritual' presence of Christ in the Lord's Supper. Geneva's academy (1559) trained pastors for France, Scotland and the Netherlands.
Why it matters
Calvinism spread farther than Lutheranism: to Scotland, the Netherlands, Hungary, Puritan England and New England, and later to Korea, where most Protestants are Presbyterian.
Life, legacy and sources
His Institutes, commentaries on most of the Bible, sermons taken down by scribes and thousands of letters survive. Geneva's consistory registers document his church discipline in detail.
Questions and debates
His role in the 1553 burning of Michael Servetus, who denied the Trinity, is still argued: Calvin pressed for conviction but asked for a quicker beheading instead.

▸John Calvin and Reformed Protestantism led the second generation of The Protestant ReformationHistorical record
The connection
Calvin, 26 years younger than Luther, turned the Reformation's ideas into a full system in the Institutes (1536) and built a model church in Geneva. Geneva's academy trained pastors who carried this 'Reformed' faith to France, the Netherlands, Scotland and Hungary, making it the Reformation's most international branch.
When and where
Geneva, Switzerland, 1536–1564; Calvin's academy opened in 1559, and from 1555 Geneva sent dozens of pastors secretly into France.
Historical evidence
Calvin's writings and the registers of Geneva's Company of Pastors record his work and the pastors sent abroad; Reformed confessions across Europe echo his teaching.
Questions and debates
Historians debate how much later 'Calvinism', such as the five points of the Synod of Dort (1619), reflects Calvin himself.
▸John Calvin and Reformed Protestantism shaped Presbyterian (Reformed) churchesHistorical record
The connection
Calvin taught that Scripture sets out four church offices, pastors, teachers, elders and deacons, with no bishops over them. John Knox, who called Geneva 'the most perfect school of Christ', took this model to Scotland, where congregations run by elected elders under regional presbyteries became the Presbyterian Church.
When and where
Geneva (Ecclesiastical Ordinances, 1541) and Scotland, where Knox returned in 1559 and Parliament adopted the Reformed faith in 1560.
Historical evidence
Calvin's Ecclesiastical Ordinances, Knox's letters and Scotland's First Book of Discipline (1560) show the Genevan model being copied.
Questions and debates
Full government by presbyteries came later, under Andrew Melville in the 1570s–1590s; how much it was Calvin's design versus a Scottish development is debated.
