For there are three things which go to complete sin: the suggestion of, the taking pleasure in, and the consenting to. Suggestion takes place either by means of memory, or by means of the bodily senses, when we see, or hear, or smell, or taste, or touch anything. And if it give us pleasure to enjoy this, this pleasure, if illicit, must be restrained. Just as when we are fasting, and on seeing food the appetite of the palate is stirred up, this does not happen without pleasure; but we do not consent to this liking, and 1 we repress it by the right of reason, which has the supremacy. But if consent shall take place, the sin will be complete, known to God in our heart, although it may not become known to men by deed. There are, then, these steps: the suggestion is made, as it were, by a serpent, that is to say, by a fleeting and rapid, i.e. a temporary, movement of bodies: for if there are also any such images moving about in the soul, they have been derived from without from the body; and if any hidden sensation of the body besides those five senses touches the soul, that also is temporary and fleeting; and therefore the more clandestinely it glides in, so as to affect the process of thinking, the more aptly is it compared to a serpent. Hence these three stages, as I was beginning to say, resemble that transaction which is described in Genesis, so that the suggestion and a certain measure of suasion is put forth, as it were, by the serpent; but the taking pleasure in it lies in the carnal appetite, as it were in Eve; and the consent lies in the reason, as it were in the man: and these things having been acted through, the man is driven forth, as it were, from paradise, i.e. from the most blessed light of righteousness, into death 2 --in all respects most righteously. For he who puts forth suasion does not compel. And all natures are beautiful in their order, according to their gradations; but we must not descend from the higher, among which the rational mind has its place assigned, to the lower. Nor is any one compelled to do this; and therefore, if he does it, he is punished by the just law of God, for he is not guilty of this unwillingly. But yet, previous to habit, either there is no pleasure, or it is so slight that there is hardly any; and to yield to it is a great sin, as such pleasure is unlawful. Now, when any one does yield, he commits sin in the heart. If, however, he also proceeds to action, the desire seems to be satisfied and extinguished; but afterwards, when the suggestion is repeated, a greater pleasure is kindled, which, however, is as yet much less than that which by continuous practice is converted into habit. For it is very difficult to overcome this; and yet even habit itself, if one does not prove untrue to himself, and does not shrink back in dread from the Christian warfare, he will get the better of under His (i.e. Christ's) leadership and assistance; and thus, in accordance with primitive peace and order, both the man is subject to Christ, and the woman is subject to the man. 3
