John Chrysostom
Catena Aurea · Matthäusevangelium 5
Ye have heard that it was said by them of old time, Thou shalt not commit adultery: But I say unto you, That whosoever looketh on a woman to lust after her hath committed adultery with her already in his heart.
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 eyesto 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.
