We thus see that there is no inconsistency in attributing the same act to God, to Satan, and to man, while, from the difference in the end and mode of action, the spotless righteousness of God shines forth at the same time that the iniquity of Satan and of man is manifested in all its deformity.

But we teach that the action of God and of men sinning is the same, according to material being, but not according to moral being. … But truly the action of God and of men is not the same according to moral being; because God acts justly from all four causes, while he punishes the Church through sinning instruments; but the action of the instruments is morally unjust and vicious. … But we teach that God is not the cause of the malice, although he is the cause of the act.
He who uses as an instrument a man freely failing, to effect what is good, is not the author of the failure. … The wicked, while they sin, are not properly instruments of God moved, that is to say, without an internal principle of motion, but metaphorically, moved in such a way that they freely move themselves.
For understanding this point, how the providence of God reacheth to and is concerned in sinful actions, we are to consider, that God neither puts evil into the hearts of men, nor stirs them up to it: for, says the apostle, Jam. 1:13. 'God cannot be tempted with evil; neither tempteth he any man.' And therefore he is not the author of sin.
As to the pravity or sin that is in actions, as God decreed the futurition of sin, or permitted it to take place, and did not hinder it; so all the sin or vitiosity that is in actions proceeds entirely from the creature, and the evil lusts and passions that are in his heart. Thus a man's taking up a stone, and throwing it, is a natural action, which the providence of God enables him to perform; but his throwing it at another man with an intention to kill him, is permitted by God, otherwise it could not take place.
