John Calvin Theologian and Protestant Reformer

John Calvin (born July 10, 1509 – died May 27, 1564) was a French theologian, pastor, and reformer during the Protestant Reformation. He was a principal figure in the development of the system of Christian theology later called Calvinism.

Born in Noyon, France, Calvin initially studied law but turned to theology after experiencing a religious conversion. His seminal work, "Institutes of the Christian Religion," became a foundational text for Protestant doctrine.

Calvin's influence extended beyond religion. He emphasized predestination and the sovereignty of God, and his reforms in Geneva established a model of church governance that influenced future generations.

As a scholar and preacher, Calvin played a vital role in shaping modern Protestantism and is remembered as one of the most significant figures in Christian history.
