John Calvin

John Calvin (born Jean Cauvin, 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. Presbyterianism and the Reformed Church also view Calvin as a central figure in their histories. Central to Calvin's beliefs are the concepts of predestination (that God has already chosen those who will achieve salvation) and total depravity (the belief that all people are born into sin).

John Calvin in "But It Does Move"
Although John Calvin had been dead for decades when Galileo published his Dialogue Concerning the Two Chief World Systems, the Catholic Church was still feeling the pressures of Calvin's theology. Thus, Galileo's advocacy of the Copernican model of the universe was seen as just one more threat to the Church.

This is view is ironic, as Calvin himself had dismissed the Copernican model within his lifetime.
