“The Manichees [heretics] have only one foundation: that it is wrong to ascribe to the good God the creation of any evil things. This does not in the slightest degree harm the orthodox faith, which does not admit that any evil nature exists in the whole universe. For the depravity and malice both of man and of the devil, or the sins that arise therefrom, do not spring from nature, but rather from the corruption of nature” (Translated by Ford Lewis Battles, John Calvin, Institutes of the Christian Religion, 163).
