John Calvin

John Calvin (1509-1564) was a French theologian and reformer whose systematic approach to Christian doctrine profoundly shaped Protestant theology. His magnum opus, Institutes of the Christian Religion (1536, expanded 1559), presented a comprehensive theological framework emphasizing God's absolute sovereignty and predestination. Calvin developed a rigorous doctrine of divine providence, arguing that God's will determines all events, and advanced the concept of double predestination - that God elects some for salvation and others for damnation. His understanding of God stressed divine transcendence, holiness, and inscrutability, while maintaining God's intimate involvement in creation through providence. Calvin's epistemology grounded knowledge of God in Scripture and the internal testimony of the Holy Spirit. His theological system, later termed Calvinism, influenced Reformed churches worldwide and sparked enduring debates about free will, divine justice, and the nature of God's relationship to evil.
