Calvinism is a Christian theology started by French church reformer John Calvin. Its central themes were the absolute sovereignty of God and the doctrine of justification by faith alone. Calvinists denied that human beings were capable of free will and elaborated on convictions of predestination. Predestination is the belief that certain persons are chosen by God for salvation while others are committed to constant damnation. Calvinists believed that the bible was the way to a life of faith.
