John Calvin was a principal figure in the development of the system of Christian theology later called Calvinism, including its doctrines of predestination and of God's absolute sovereignty in the salvation of the human soul from death and eternal damnation. Calvinist doctrines were influenced by and elaborated upon the Augustinian and other Christian traditions. Various Congregational, Reformed and Presbyterian churches, which look to Calvin as the chief expositor of their beliefs, have spread throughout the world. Calvin produced commentaries on most of the books of the Bible. He also wrote many letters and treatises. Calvin provided many of the foundational documents for reformed churches, including documents on the catechism, the liturgy, and church governance. He also produced several confessions of faith in order to unite the churches.
