II. What were the causes of the first sin?

The first sin of man had its origin, not in God, but was brought about by the instigation of the devil, and the free will of man. The devil tempted man to fall away from God; and man, yielding to this temptation, willingly separated himself from God. And although God left man to himself in this temptation, yet he is not the cause of the fall, the sin, or the destruction of man; because, in this desertion, he neither designed, nor accomplished any of these things. He merely put man upon trial, to show that he is entirely unable to do, or to retain aught that is good, if he is not preserved and controlled by the Holy Spirit; and with this, his trial, God, in his just judgment, permitted the sin of man to concur.

The wisdom of man reasons and concludes differently, as is evident from the objection which we often hear: He who withdraws, in the time of temptation, that grace, without which it is not possible to prevent a fall, is the cause of the fall. But God withdrew, from man, his grace, in the trial through which he was called to pass, so that man could not but fall. Therefore, God was the cause of the fall of man. Ans. The major proposition is true only of him who withholds grace, when he is obligated not to withdraw it; who takes it from him who is desirous of it, and does not wilfully reject it; and who withholds it out of malice. But it is not true of him who is not bound to preserve the grace which he at first gave; and who does not withdraw it from him who desires it, but only from him who is willing for him so to do, and who, of his own account, rejects the grace that is proffered him; and who does not, therefore, withhold it because he envies the sinner righteousness and eternal life; but that he may make a trial of him to whom he has imparted his grace. He who thus forsakes any one, is not the cause of sin, even though it necessarily follows this desertion and withdrawal of grace. And in as much as God withheld his grace from man in the time of his temptation, not in the first, but in the last manner just described, he is not the cause of his sin and destruction; but man alone is guilty for wilfully rejecting the grace of God.

It is again objected, by men of carnal minds: He who wills to tempt any one, when he certainly knows that he will fall, if he be tempted, wills the sin of him who falls. God willed that man should be tempted by the devil, when he knew that he would certainly fall; for if he had not willed it, man could not have been tempted. Therefore, God is the cause of the fall. Ans. We deny the major, if it be understood in its naked and simple form; for he is not the cause of sin, who wills that he who may fall should be tempted for the purpose of being put upon trial, and for the manifestation of the weakness of the creature, which was the sense in which God tempted man. But the devil tempting man, with the design that he might sin, and separate himself from God; and man, of his own free will, yielding to this temptation, in opposition to the command of God; they are both the cause of sin, of which we shall speak more hereafter.
