 John Calvin rejected the idea that God permits rather than actively decrees the damnation of sinners, as well as other evil.Calvin did not believe God to be guilty of sin, but rather he considered God inflicting sin upon his creations to be an unfathomable mystery (it would seem that God was simultaneously willing and not willing sin to befall humans).Though he maintained God's predestination applies to damnation as well as salvation, he taught that the damnation of the damned is caused by their sin, but that the salvation of the saved is solely caused by God.
