"But I say to you, that whosoever shall look on a woman to lust after her, hath already committed adultery with her in his heart." - Matthew 5:28
Some famous commentary:
But I say to you, that whosoever shall look on a woman to lust after her, hath already committed adultery with her in his heart. - Matthew 5:28
"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 betaken, 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 endeavor 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 warningis meant for the whole body." - John Chrysostom
"But I say to you, that whosoever shall look on a woman to lust after her, hath already committed adultery with her in his heart. - Matthew 5:28
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." - Augustine of Hippo
