Charles Haddon (CH) Spurgeon (19 June 1834 – 31 January 1892) was a British Particular Baptist preacher. Spurgeon remains highly influential among Christians of various denominations, among whom he is known as the "Prince of Preachers". He was a strong figure in the Reformed Baptist tradition. Spurgeon produced powerful sermons of penetrating thought and precise exposition. Many Christians have discovered Spurgeon's messages to be among the best in Christian literature.
John Calvin (1509–1564) was an influential French theologian and pastor during the Protestant Reformation. He was a principal figure in the development of the system of Christian theology later called Calvinism. John Calvin was Martin Luther's successor as the preeminent Protestant theologian. Calvin made a powerful impact on the fundamental doctrines of Protestantism, and is widely credited as the most important figure in the second generation of the Protestant Reformation.
