John Calvin (1509-1564) was a French Reformation theologian and founder of the tradition that today is most strongly represented in Presbyterian and Reformed churches. Calvin worked out his theological views while attempting to reform the Swiss city of Geneva. Calvin’s thought puts great emphasis on the sovereignty of God and the ways in which sin deforms the whole of human existence. Epistemologically, Calvinism puts emphasis on an innate sense of God’s reality that has been damaged by sin, on revelation and on the inner testimony of the Holy Spirit.1
