Matthew 5:28

For, when one reads of God as being "the searcher and witness of the heart; " when His prophet is reproved by His discovering to him the secrets of the heart; when God Himself anticipates in His people the thoughts of their heart, "Why think ye evil in your hearts? " when David prays "Create in me a clean heart, O God," and Paul declares, "With the heart man believeth unto righteousness," and John says, "By his own heart is each man condemned; " when, lastly, "he who looketh on a woman so as to lust after her, hath already committed adultery with her in his heart," -then both points are cleared fully up, that there is a directing faculty of the soul, with which the purpose of God may agree; in other words, a supreme principle of intelligence and vitality (for where there is intelligence, there must be vitality), and that it resides in that most precious part of our body to which God especially looks: so that you must not suppose, with Heraclitus, that this sovereign faculty of which we are treating is moved by some external force; nor with Moschion, that it floats about through the whole body; nor with Plato, that it is enclosed in the head; nor with Zenophanes, that it culminates in the crown of the head; nor that it reposes in the brain, according to the opinion of Hippocrates; nor around the basis of the brain, as Herophilus thought; nor in the membranes thereof, as Strato and Erasistratus said; nor in the space between the eyebrows, as Strato the physician held; nor within the enclosure of the breast, according to Epicurus: but rather, as the Egyptians have always taught, especially such of them as were accounted the expounders of sacred truths; in accordance, too, with that verse of Orpheus or Empedocles:

The emotions of sin, indeed, when not resulting in effects, are usually imputed to the soul: "Whosoever looketh on a woman to lust after, hath already in his heart committed adultery with her." But what has the flesh alone, without the soul, ever done in operations of virtue, righteousness, endurance, or chastity? What absurdity, however, it is to attribute sin and crime to that substance to which you do not assign any good actions or character of its own! Now the party which aids in the commission of a crime is brought to trial, only in such a way that the principal offender who actually committed the crime may bear the weight of the penalty, although the abettor too does not escape indictment.

Enough, that the Lord has said faults are committed in the mind and the conscience. If concupiscence or malice have ascended into a man's heart, He saith it is held as a deed. You therefore have given a guarantee; which clearly has "ascended into your heart," which you can neither contend you were ignorant of nor unwilling; for when you gave the guarantee, you knew that you did it; when you knew, of course you were willing: you did it as well in act as in thought; nor can you by the lighter charge exclude the heavier, so as to say that it is clearly rendered false, by giving a guarantee I for what you do not actually perform.

For His own servants, may the Lord by His mercy take care that to them it may be lawful even to presume on His goodness! But why are we a (source of) danger to our neighbour? why do we import concupiscence into our neighbour? which concupiscence, if God, in "amplifying the law," do not dissociate in (the way of) penalty from the actual commission of fornication, I know not whether He allows impunity to him who has been the cause of perdition to some other.

The Lord Himself, in short, when rebuking our thoughts, includes in His censures this aspect of the flesh, (man's heart), the citadel of the soul: "Why think ye evil in your hearts? " and again: "Whosoever looketh on a woman, to lust after her, hath already committed adultery with her in his heart." So that even the thought, without operation and without effect, is an act of the flesh.

"Whosoever looketh on a woman to lust after her, hath committed adultery with her already in his heart." Therefore, even for this cause it is most fitting that the soul, without at all waiting for the flesh, should be punished for what it has done without the partnership of the flesh.

But how far wider an extent the Lord assigns to those crimes we are sure: when He defines adultery to consist even in concupiscence, "if one shall have cast an eye lustfully on," and stirred his soul with immodest commotion; when He judges murder to consist even in a word of curse or of reproach, and in every impulse of anger, and in the neglect of charity toward a brother just as John teaches, that he who hates his brother is a murderer.

For, since he says that married persons make this their solicitude, "how to please one another" (not, of course, morally, for a good solicitude he would not impugn); and (since), he wishes them to be understood to be solicitous about dress, and ornament, and every kind of personal attraction, with a view to increasing their power of allurement; (since), moreover, to please by personal beauty and dress is the genius of carnal concupiscence, which again is the cause of fornication: pray, does second marriage seem to you to border upon fornication, since in it are detected those ingredients which are appropriate to fornication? The Lord Himself said, "Whoever has seen a woman with a view to concupiscence has already violated her in his heart." But has he who has seen her with a view to marriage done so less or more? What if he have even married her?-which he would not do had he not desired her with a view to marriage, and seen her with a view to concupiscence; unless it is possible for a wife to be married whom you have not seen or desired.

Because adultery is a serious sin and in order to uproot it, lest our conscience be defiled, he forbade even lust, which is the fuel of adultery. According to the words of blessed James in his epistle, “Lust when it has conceived gives birth to sin; and sin when it is full-grown brings forth death.” The Holy Spirit speaks concerning this to David: “Happy shall he be who takes your little ones and dashes them against the rock.” The symbolism here is that the blessed and truly evangelical person roots out the desires and lust of the flesh arising from human weakness. He does this immediately before they grow, at the onset, through faith in Christ who has been described as a rock.

Having now finished the former commandment, and having extended it unto the height of self-denial, He, advancing in course and order, proceeds accordingly unto the second, herein too obeying the law.

For beginning from those passions, which most belong to our whole race, anger, I mean, and desire (for it is these chiefly that bear absolute sway within us, and are more natural than the rest); He with great authority, even such as became a legislator, both corrected them, and reduced them to order with all strictness. For He said not that the adulterer merely is punished; but what He had done with respect to the murderer, this He doth here also, punishing even the unchaste look: to teach thee wherein lies what He had more than the scribes. Accordingly, He saith, "He that looketh upon a woman to lust after her hath already committed adultery with her:" that is, he who makes it his business to be curious about bright forms, and to hunt for elegant features, and to feast his soul with the sight, and to fasten his eyes on fair countenances. For He came to set free from all evil deeds not the body only, but the soul too before the body. Thus, because in the heart we receive the grace of the Spirit, He cleanses it out first.

"And how," one may say, "is it possible to be freed from desire?" I answer, first, if we were willing, even this might be deadened, and remain inactive.

In the next place, He doth not here take away desire absolutely, but that desire which springs up in men from sight. For he that is curious to behold fair countenances, is himself chiefly the enkindler of the furnace of that passion, and makes his own soul a captive, and soon proceeds also to the act.

Thus we see why He said not, "whosoever shall lust to commit adultery," but, "whosoever shall look to lust." And in the case of anger He laid down a certain distinction, saying, "without a cause," and "for nought;" but here not so; rather once for all He took away the desire. Yet surely both are naturally implanted, and both are set in us for our profit; both anger, and desire: the one that we may chastise the evil, and correct those who walk disorderly; the other that we may have children, and that our race may be recruited by such successions.

Why then did He not make a distinction here also? Nay, very great is the distinction which, if thou attend, thou wilt see here also included. For He said not simply, "whosoever shall desire," since it is possible for one to desire even when sitting in the mountains; but, "Whosoever shall look to lust;" that is to say, he who gathers in lust unto himself; he who, when nothing compels him, brings in the wild beast upon his thoughts when they are calm. For this comes no longer of nature, but of self-indulgence. This even the ancient Scripture corrects from the first, saying, "Contemplate not beauty which is another's." And then, lest any one should say, "what then, if I contemplate, and be not taken captive," He punishes the look, lest confiding in this security thou shouldest some time fall into sin. "What then," one may say, "if I should look, and desire indeed, but do no evil?" Even so thou art set among the adulterers. For the Lawgiver hath pronounced it, and thou must not ask any more questions. For thus looking once, twice, or thrice, thou wilt perhaps have power to refrain; but if thou art continually doing this, and kindling the furnace, thou wilt assuredly be taken; for thy station is not beyond that nature which is common to men. As we then, if we see a child holding a knife, though we do not see him hurt, beat him, and forbid his ever holding it; so God likewise takes away the unchaste look even before the act, lest at any time thou shouldest fall in act also. For he who hath once kindled the flame, even when the woman whom he hath beheld is absent, is forming by himself continually images of shameful things, and from them often goes on even to the deed. For this cause Christ takes away even that embrace which is in the heart only.

For in truth greater is the struggle on beholding, and not possessing the object of fondness: nor is the pleasure so great which we reap from the sight, as the mischief we undergo from increasing this desire; thus making our opponent strong, and giving more scope to the devil, and no longer able to repulse him, now that we have brought him into our inmost parts, and have thrown our mind open unto him. Therefore He saith, "commit no adultery with thine eyes, and thou wilt commit none with thy mind."

For one may indeed behold in another way, such as are the looks of the chaste; wherefore he did not altogether prohibit our seeing, but that seeing which is accompanied with desire. And if He had not meant this, He would have said simply, "He who looketh on a woman." But now He said not thus, but, "He who looketh to lust," "he who looketh to please his sight."

For not at all to this end did God make thee eyes, that thou shouldest thereby introduce adultery, but that, beholding His creatures, thou shouldest admire the Artificer.

Just then as one may feel wrath at random, so may one cast looks at random; that is, when thou doest it for lust. Rather, if thou desirest to look and find pleasure, look at thine own wife, and love her continually; no law forbids that. But if thou art to be curious about the beauties that belong to another, thou art injuring both thy wife by letting thine eyes wander elsewhere, and her on whom thou hast looked, by touching her unlawfully. Since, although thou hast not touched her with the hand, yet hast thou caressed her with thine eyes; for which cause this also is accounted adultery, and before that great penalty draws after it no slight one of its own. For then all within him is filled with disquiet and turmoil, and great is the tempest, and most grievous the pain, and no captive nor person in chains can be worse off than a man in this state of mind. And oftentimes she who hath shot the dart is flown away, while the wound even so remains. Or rather, it is not she who hath shot the dart, but thou gavest thyself the fatal wound, by thine unchaste look. And this I say to free modest women from the charge: since assuredly, should one deck herself out, and invite towards herself the eyes of such as fall in her way; even though she smite not him that meets with her, she incurs the utmost penalty: for she mixed the poison, she prepared the hemlock, even though she did not offer the cup. Or rather, she did also offer the cup, though no one were found to drink it.

(Hom. xvii.) The Lord having explained how much is contained in the first commandment, namely, Thou shalt not kill, proceeds in regular order to the second.

If you permit yourself to gaze often on fair countenances you will assuredly be taken, even though you may be able to command your mind twice or thrice. For you are not exalted above nature and the strength of humanity. She too who dresses and adorns herself for the purpose of attracting men's eyes to her, though her endeavour should fail, yet shall she be punished hereafter; seeing she mixed the poison and offered the cup, though none was found who would drink thereof. For what the Lord seems to speak only to the man, is of equal application to the woman; inasmuch as when He speaks to the head, the warning is meant for the whole body.

(Verse 28.) Whoever looks at a woman to lust for her has already committed adultery with her in his heart. Between passion and pre-passion, that is, between feeling and intense feeling, there is a difference: passion is considered a vice, while pre-passion, although it carries the fault of initiation, is not held accountable in the crime. Therefore, whoever looks at a woman and his soul is tickled, he is struck by pre-passion. But if he agrees and allows himself to be affected by the thought, as it is written in David: They passed into the feeling of their hearts (Ps. 73:7), he moves from pre-passion to passion, and it is not a lack of will to sin, but an opportunity. Therefore, whoever sees a woman with lustful intent, that is, if he looks at her in order to lust after her, he is rightly said to commit adultery in his heart.

Between πάθος and προπάθεια, that is between actual passion and the first spontaneous movement of the mind, there is this difference: passion is at once a sin; the spontaneous movement of the mind, though it partakes of the evil of sin, is yet not held for an offence committedh. When then one looks upon a woman, and his mind is therewith smitten, there is propassion; if he yields to this he passes from propassion to passion, and then it is no longer the will but the opportunity to sin that is wanting. Whosoever, then, looketh on a woman to lust after her, that is, so looks on her as to lust, and cast about to obtain, he is rightly said to commit adultery with her in his heart.

It is well worthy of consideration that He did not say, Whosoever lusts after a woman, but, Whosoever looks on a woman to lust after her, i.e. turns toward her with this aim and this intent, that he may lust after her; which, in fact, is not merely to be tickled by fleshly delight, but fully to consent to lust; so that the forbidden appetite is not restrained, but satisfied if opportunity should be given.

34. 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 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 — 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.
35. Hence, just as we arrive at sin by three steps—suggestion, pleasure, consent,— so of sin itself there are three varieties—in heart, in deed, in habit,— as it were, three deaths: one, as it were, in the house, i.e. when we consent to lust in the heart; a second now, as it were, brought forth outside the gate, when assent goes forward into action; a third, when the mind is pressed down by the force of bad habit, as if by a mound of earth, and is now, as it were, rotting in the sepulchre. And whoever reads the Gospel perceives that our Lord raised to life these three varieties of the dead. And perhaps he reflects what differences may be found in the very word of Him who raises them, when He says on one occasion, Damsel, arise; on another, Young man, I say unto you, Arise; and when on another occasion He groaned in the spirit, and wept, and again groaned, and then afterwards cried with a loud voice, Lazarus, come forth.
36. And therefore, under the category of the adultery mentioned in this section, we must understand all fleshly and sensual lust. For when Scripture so constantly speaks of idolatry as fornication, and the Apostle Paul calls avarice by the name of idolatry, who doubts but that every evil lust is rightly called fornication, since the soul, neglecting the higher law by which it is ruled, and prostituting itself for the base pleasure of the lower nature as its reward (so to speak), is thereby corrupted? And therefore let every one who feels carnal pleasure rebelling against right inclination in his own case through the habit of sinning, by whose unsubdued violence he is dragged into captivity, recall to mind as much as he can what kind of peace he has lost by sinning, and let him cry out, O wretched man that I am! Who shall deliver me from the body of this death? I thank God through Jesus Christ. For in this way, when he cries out that he is wretched, in the act of bewailing he implores the help of a comforter. Nor is it a small approach to blessedness, when he has come to know his wretchedness; and therefore blessed also are they that mourn, for they shall be comforted.

(cont. Faust. xix. 23.) He then goes on to correct the error of the Pharisees, declaring, Whoso looketh upon a woman to lust after her, hath committed adultery already with her in his heart. For the commandment of the Law, Thou shall not lust after thy neighbour's wife, (Exod. 20:17.) the Jews understood of taking her away, not of committing adultery with her.

(Serm. in Mont. i. 12.) For there are three things which make up a sin; suggestion either through the memory, or the present sense; if the thought of the pleasure of indulgence follows, that is an unlawful thought, and to be restrained; if you consent then, the sin is complete. For prior to the first consent, the pleasure is either none or very slight, the consenting to which makes the sin. But if consent proceeds on into overt act, then desire seems to be satiated and quenched. And when suggestion is again repeated, the contemplated pleasure is greater, which previous to habit formed was but small, but now more difficult to overcome.

Gerontius of Petra said, ‘Many people who are tempted by pleasures of the flesh do not sin with the body but lust with the mind; they keep their bodily virginity but lust in their heart. It is better then, beloved, to do what is written, “Let everyone keep a close guard upon his heart” (Prov. 4:23).’

A brother asked some of the monks whether evil thoughts defiled a man. When they were asked this question, some said, ‘Yes,’ but some said, ‘No, for if that were so, we ordinary people could not be saved. If we think of vile actions but do not do them, it is this which brings salvation.’ The questioner was discontented with the monks’ diverse answers, and he went to an experienced hermit and asked him about it. He replied, ‘Everyone is required to act according to his capacity.’ Then the brother asked him, ‘For the Lord’s sake, explain this saying to me.’ So he said, ‘Look here, suppose there was a valuable jug and two monks came in, one of whom had a great capacity for a disciplined life, and the other a small capacity. Suppose that the mind of the more disciplined man is moved at the sight of the jug and he says inwardly, “I’d like to have that jug,” but the idea leaves him at once, and he puts away any thought of it, then he would not be defiled. But if the less disciplined man covets the jug and is strongly moved by an impulse to take it, and yet after a struggle he does not take it, he would not be defiled either.’

A hermit used to say, ‘A lustful thought is brittle like papyrus. When it is thrust at us, if we do not accept it but throw it away it breaks easily. If it allures us and we keep playing with it, it becomes as difficult to break as iron. We need discernment to know that those who consent lose hope of salvation and for those who do not consent, a crown is made ready.’

(Mor. xxi. 2.) But whoso casts his eyes about without caution will often be taken with the pleasure of sin, and ensnared by desires begins to wish for what he would not. Great is the strength of the flesh to draw us downwards, and the charm of beauty once admitted to the heart through the eye, is hardly banished by endeavour. We must therefore take heed at the first, we ought not to look upon what it is unlawful to desire. For that the heart may be kept pure in thought, the eyes, as being on the watch to hurry us to sin, should be averted from wanton looks.

. That is, if one stands gazing and examining, kindling desire by looking, and looking again to desire even more, he has already brought the evil to readiness in his heart. If he did not add to it the deed itself, what of it? He was not able. If he had been able, he would immediately have perpetrated the evil. But nevertheless understand that if we have lusted, and then were prevented from committing the deed, clearly we were protected by grace. And if a woman has adorned herself in order to attract others, yet does not succeed in attracting, she is guilty of having mixed the poison into the cup, though no one drank.
