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.”[Matthew 5:28-29] 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 ...

1. And that the Lord did not abrogate the natural [precepts] of the law, by which man is justified, which also those who were justified by faith, and who pleased God, did observe previous to the giving of the law, but that He extended and fulfilled them, is shown from His words. “For,” He remarks, “it has been said to them of old time, Do not commit adultery. But I say unto you, That every one who hath looked upon a woman to lust after her, hath committed adultery with her already in his heart.”[Matthew 5:27-28] And again: “It has been said, Thou shalt not kill. But I say unto you, Every one who is angry with his brother without a cause, shall be in danger of the judgment.” And, “It hath been said, Thou shalt not forswear thyself. But I say unto you, Swear ...

... and to follow His word unswervingly, while they abstain not only from evil deeds, but even from the desire after them. But He has also increased the feeling of reverence; for sons should have more veneration than slaves, and greater love for their father. And therefore the Lord says, “As to every idle word that men have spoken, they shall render an account for it in the day of judgment.” And, “he who has looked upon a woman to lust after her, hath committed adultery with her already in his heart;”[Matthew 5:28] and, “he that is angry with his brother without a cause, shall be in danger of the judgment.” [All this is declared,] that we may know that we shall give account to God not of deeds only, as slaves, but even of words and thoughts, as those who have ...

How? or when spoke I an unseemly word to you? Did I not always think of you as a lady? Did I not always respect you as a sister? Why do you falsely accuse me of this wickedness and impurity?” With a smile she replied to me, “The desire of wickedness[Matthew 5:28] arose within your heart.

There is sin in such a case, and the sin is great,” said she; “for the thoughts of a righteous man should be righteous. For by ...

“I charge you,” said he, “to guard your chastity, and let no thought enter your heart of another man’s wife, or of fornication, or of similar iniquities; for by doing this you commit a great sin. But if you always remember your own wife, you will never sin. For if this thought[Matthew 5:28] enter your heart, then you will sin; and if, in like manner, you think other wicked thoughts, you commit sin. For this thought is great sin in a servant of God. But if any one commit this wicked deed, he works death for himself. Attend, therefore, and refrain from this thought; for where purity dwells, there iniquity ought not to enter the heart of a ...

Solomon, accordingly, who was a king and a prophet, said: “Let thine eyes look right on, and let thine eyelids look straight before thee: make straight paths for your feet.” And the voice of the Gospel teaches still more urgently concerning chastity, saying: “Whosoever looketh on a woman who is not his own wife, to lust after her, hath committed adultery with her already in his heart.”[Matthew 5:28] “And he that marrieth,” says [the Gospel], “her that is divorced from her husband, committeth adultery; and whosoever putteth away his wife, saving for the cause of fornication, causeth her to commit adultery.” Because Solomon says: “Can a man take ...

But we are so far from practising promiscuous intercourse, that it is not lawful among us to indulge even a lustful look. “For,” saith He, “he that looketh on a woman to lust after her, hath committed adultery already in his heart.”[Matthew 5:28] Those, then, who are forbidden to look at anything more than that for which God formed the eyes, which were intended to be a light to us, and to whom a wanton look is adultery, the eyes being made for other purposes, and who are to be called to ...

On behalf of those, then, to whom we apply the names of brothers and sisters, and other designations of relationship, we exercise the greatest care that their bodies should remain undefiled and uncorrupted; for the Logos[Matthew 5:28] again says to us, “If any one kiss a second time because it has given him pleasure, [he sins];” adding, “Therefore the kiss, or rather the salutation, should be given with the greatest care, since, if there be mixed with it the least defilement of ...

Men, therefore, affording to women a noble example of truth, ought to be ashamed at their stripping before them, and guard against these dangerous sights; “for he who has looked curiously,” it is said, “hath sinned already.”[Matthew 5:28] At home, therefore, they ought to regard with modesty parents and domestics; in the ways, those they meet; in the baths, women; in solitude, themselves; and everywhere the Word, who is everywhere, “and without Him was not anything.” For so only ...

The Gnostic, therefore, will abstain from errors in speech, and thought, and sensation, and action, having heard “that he that looks so as to lust hath committed adultery;”[Matthew 5:28] and reflecting that “blessed are the pure in heart, for they shall see God;” and knowing this, “that not what enters into the mouth defileth, but that it is what cometh forth by the mouth that defileth the man.

For, in reality, he that cannot contain the generative word is to be punished; for this is an irrational passion of the soul approaching garrulity. “The faithful man chooses to conceal things in his spirit.” Things, then, that depend on choice are subjects for judgment. “For the Lord searcheth the hearts and reins.” “And he that looketh so as to lust”[Matthew 5:28] is judged. Wherefore it is said, “Thou shalt not lust.” And “this people honoureth Me with their lips,” it is said, “but their heart is far from Me.” For God has respect to the very thought, since Lot’s wife, who had merely voluntarily turned ...

For “love hides the multitude of sins.” And they are blotted out by Him “who desireth the repentance rather than the death of a sinner.” And those are not reckoned that are not the effect of choice; “for he who has lusted has already committed adultery,”[Matthew 5:28] it is said. And the illuminating Word forgives sins: “And in that time, saith the Lord, they shall seek for the iniquity of Israel, and it shall not exist; and the sins of Judah, and they shall not be found.” “For who is like ...

Come to this point, I recollect one who called himself a Gnostic. For, expounding the words, “But I say unto you, he that looketh on a woman to lust after, hath committed adultery,”[Matthew 5:28] he thought that it was not bare desire that was condemned; but if through the desire the act that results from it proceeding beyond the desire is accomplished in it. For dream employs phantasy and the body. Accordingly, the historians relate the following decision of Bocchoris the just. A youth, falling in love with a courtezan, persuades the girl, for a stipulated reward, to come to him next day. But his ...

What, then, shall we say of the Gnostic himself? “Know ye not,” says the apostle, “that ye are the temple of God?” The Gnostic is consequently divine, and already holy, God-bearing, and God-borne. Now the Scripture, showing that sinning is foreign to him, sells those who have fallen away to strangers, saying, “Look not on a strange woman, to lust,”[Matthew 5:28] plainly pronounces sin foreign and contrary to the nature of the temple of God. Now the temple is great, as the Church, and it is small, as the man who preserves the seed of Abraham. He, therefore, who has God resting in him will not desire aught else. At once leaving all hindrances, and despising all matter which ...

But how far wider an extent the Lord assigns to those crimes we are sure: when He defines adultery to consist even in concupiscence,[Matthew 5:28] “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 ...

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.[Matthew 5:28] 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 ...

Accordingly the flesh is blamed in the Scriptures, because nothing is done by the soul without the flesh in operations of concupiscence, appetite, drunkenness, cruelty, idolatry, and other works of the flesh,—operations, I mean, which are not confined to sensations, but result in effects. 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.”[Matthew 5:28] But what has the flesh alone, without the soul, ever done in operations of virtue, righteousness, endurance, or chastity?

The Lord Himself said, “Whoever has seen a woman with a view to concupiscence has already violated her in his heart.”[Matthew 5:28] But has he who has seen her with a view to marriage done so less or more?

The Saviour also saying, “I say unto you, Resist not evil;” and, “Whoever shall be angry with his brother, shall be in danger of the judgment;” and, “Whosoever shall look upon a woman to lust after her, hath already committed adultery with her in his heart;”[Matthew 5:28] and in issuing certain other commands,—conveys no other meaning than this, that it is in our own power to observe what is commanded.

Chapter XIII. St. Ambrose, treating of the words in the Gospel concerning eunuchs, condemns those who make themselves such. Those only deserve praise who have through continence gained the victory over themselves, but no one is to be compelled to live this life, as neither Christ nor the Apostle laid down such a law, so that the marriage vow is not to be blamed, though that of chastity is better.

CCEL Footnote 3389 (In-Text, Margin)

... existence; but then consider whether this tends not rather to a declaration of weakness than to a reputation for strength. On this principle no one should fight lest he be overcome, nor make use of his feet, fearing the danger of stumbling, nor let his eyes do their office because he fears a fall through lust. But what does it profit to cut the flesh, when there may be guilt even in a look? “For whosoever looketh on a woman to lust after her hath committed adultery already with her in his heart.”[Matthew 5:28] And likewise she who looks on a man to lust after him commits adultery. It becomes us, then, to be chaste, not weak, to have our eyes modest, not feeble.

... elsewhere, “Blessed are those of a pure heart; for they shall see God.” I think that this last statement is made regarding those whom conscience accuses of the guilt of no sin; concerning whom I think that John also spoke in his Epistle when he said, “If our heart condemn us not, then have we confidence towards God, and whatsoever we ask we shall receive from him.” I do not wish you to think that you have escaped the accusation of sin, although act does not follow desire, since it is written, “Whosoever[Matthew 5:28] looketh on a woman to lust after her, hath already committed adultery with her in his heart.” And do not say, “I had the thought, indeed, but I did not carry it out in act”; for it is unlawful even to desire that which it is unlawful to do. ...

... class="sc">For it is possible even for one who has no money to be by no means free from the malady of covetousness, and for the blessing of penury to do him no good, because he has not been able to root out the sin of cupidity: delighting in the advantages of poverty, not in the merit of the virtue, and satisfied with the burden of necessity, not without coldness of heart. For just as the word of the gospel declares of those who are not defiled in body, that they are adulterers in heart;[Matthew 5:28] so it is possible that those who are in no way pressed down with the weight of money may be condemned with the covetous in disposition and intent. For it was the opportunity of possessing which was wanting in their case, and not the will for it: ...

... Onan the son of the patriarch Judah was smitten by the Lord; and which is termed by Scripture uncleanness: of which the Apostle says: “But I say to the unmarried and to widows, that it is good for them if they abide even as I. But if they do not contain let them marry: for it is better to marry than to burn;” (3) that which is conceived in heart and mind, of which the Lord says in the gospel: “Whosoever looketh on a woman to lust after her hath already committed adultery with her in his heart.”[Matthew 5:28] And these three kinds the blessed Apostle tells us must be stamped out in one and the same way. “Mortify,” says he, “your members which are upon the earth, fornication, uncleanness, lust, etc.” And again of two of them he says to the Ephesians: “Let ...

... himself; for because the wolf had put on sheep’s clothing, the Shepherd of all became a Lamb in the flocks, in order that when the greedy one had been bold against the Meek, the Mighty One might rend that Eater. The Holy One dwelt bodily in the womb; and He dwelt spiritually in the mind. Mary that conceived Him abhorred the marriage bed; let not that soul commit whoredom in the which He dwelleth. Because Mary perceived Him, she left her betrothed: He dwelleth in chaste virgins, if they perceive Him.[Matthew 5:28] The deaf perceive not the mighty thunder, neither does the heady man the sound of the commandment. For the deaf is bewildered in the time of the thunderclap, the heady man is bewildered also at the voice of instruction; if fearful thunder terrifies ...
