Puritans were those who followed the doctrine of John Calvin and wanted to purify the Church of England. They believe that human beings were predestined by God before they were born. Some were God's chosen people while others were dammed to hell. No church nor good works could save people. The sign of being God's elect was the success in his work or the prosperity in his calling. They also argued that everyone must read the Bible in order to find God's will and establish a direct contact with God. These beliefs had great impact on American culture.
