Mateus 5

Mateus 5:31-32

Concerning chastity, He uttered such sentiments as these: "Whosoever looketh upon a woman to lust after her, hath committed adultery with her already in his heart before God." And, "If thy right eye offend thee, cut it out; for it is better for thee to enter into the kingdom of heaven with one eye, than, having two eyes, to be cast into everlasting fire." And, "Whosoever shall marry her that is divorced from another husband, committeth adultery." And, "There are some who have been made eunuchs of men, and some who were born eunuchs, and some who have made themselves eunuchs for the kingdom of heaven's sake; but all cannot receive this saying." So that all who, by human law, are twice married, are in the eye of our Master sinners, and those who look upon a woman to lust after her. For not only he who in act commits adultery is rejected by Him, but also he who desires to commit adultery: since not only our works, but also our thoughts, are open before God. — The First Apology, Chapter XV
