Matthew 5:28

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

"Thou shalt not commit adultery," that is, Thou shalt go no where but to thy lawful wife. For if you exact this of your wife, you ought to do the same, for the husband ought to go before the wife in virtue. It is a shame for the husband to say that this is impossible. Why not the husband as well as the wife? And let not him that is unmarried suppose that he does not break this commandment by fornication; you know the price wherewith you have been bought, you know what you eat and what your drink [ed. note, g: Nic. inserts here, from the original, "immo quem manduces, quem bibas."] therefore keep yourself from fornications. Forasmuch as all such acts of lust pollute and destroy God's image, (which you are,) the Lord who knows what is good for you, gives you this precept that you may not pull down His temple which you have begun to be.

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 shalt not lust after thy neighbour's wife," [Ex 20:17] the Jews understood of taking her away, not of committing adultery with her.

Between παθος and προπαθεια, 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 committed. [ed. note, h: In this passage S. Jerome, who seems to have introduced the word propassio, προπαθεια, into theology, uses it somewhat in a sense of his own; viz. as involving something of the nature of sin; vid. also Comm. in Ezek. xviii, 1, 2. The word is more commonly applied to our Lord, as denoting the mode and extent in which His soul was affected by what in others became παθος. In us passion precedes reason, in Him it followed, or was a προπαθεια. vid. S. Jerome in Matt. xxvi. 37. Leo n. Ep. 35. Damasc. F. O. iii. 20 &c. &c.] 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.

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.

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.

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 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 warning is meant for the whole body.

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. …

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.” 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 not at all; but let your conversation be, Yea, yea, and Nay, nay.” And other statements of a like nature. …

5. The laws of bondage, however, were one by one promulgated to the people by Moses, suited for their instruction or for their punishment, as Moses himself declared: “And the Lord commanded me at that time to teach you statutes and judgments.” These things, therefore, which were given for bondage, and for a sign to them, He cancelled by the new covenant of liberty. But He has increased and widened those laws which are natural, and noble, and common to all, granting to men largely and without grudging, by means of adoption, to know God the Father, and to love Him with the whole heart, 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 concerning chastity, the holy word teaches us not only not to sin in act, but not even in thought, not even in the heart to think of any evil, nor look on another man’s wife with our eyes to lust after her. 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.” “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 fire in his bosom, and his clothes not be burned? O …

It is, however, nothing wonderful that they should get up tales about us such as they tell of their own gods, of the incidents of whose lives they make mysteries. But it behoved them, if they meant to condemn shameless and promiscuous intercourse, to hate either Zeus, who begat children of his mother Rhea and his daughter Koré, and took his own sister to wife, or Orpheus, the inventor of these tales, which made Zeus more unholy and detestable than Thyestes himself; for the latter defiled his daughter in pursuance of an oracle, and when he wanted to obtain the kingdom and avenge himself. But we are so far from practising promiscuous intercourse, that it is not lawful among us to indulge even a lustful look. …

For what, think you, O men, is the Hermes of Typho, and that of Andocides, and that of Amyetus? Is it not evident to all that they are stones, as is the veritable Hermes himself? As the Halo is not a god, and as the Iris is not a god, but are states of the atmosphere and of the clouds; and as, likewise, a day is not a god, nor a year, nor time, which is made up of these, so neither is sun nor moon, by which each of those mentioned above is determined. Who, then, in his right senses, can imagine Correction, and Punishment, and Justice, and Retribution to be gods? For neither the Furies, nor the Fates, nor Destiny are gods, since neither Government, nor Glory, nor Wealth are gods, which last [as Plutus] painters represent as blind. But if you deify Modesty, and Love, and Venus, let these be followed by Infamy, and Passion, and Beauty, and Intercourse. …

The baths are opened promiscuously to men and women; and there they strip for licentious indulgence (for from looking, men get to loving), as if their modesty had been washed away in the bath. Those who have not become utterly destitute of modesty shut out strangers; but bathe with their own servants, and strip naked before their slaves, and are rubbed by them; giving to the crouching menial liberty to lust, by permitting fearless handling. For those who are introduced before their naked mistresses while in the bath, study to strip themselves in order to audacity in lust, casting off fear in consequence of the wicked custom. …

But the knowledge of those who think themselves wise, whether the barbarian sects or the philosophers among the Greeks, according to the apostle, “puffeth up.” But that knowledge, which is the scientific demonstration of what is delivered according to the true philosophy, is founded on faith. Now, we may say that it is that process of reason which, from what is admitted, procures faith in what is disputed. Now, faith being twofold, the faith of knowledge and that of opinion, nothing prevents us from calling demonstration twofold, the one resting on knowledge, the other on opinion; since also knowledge and foreknowledge are designated as twofold, that which is essentially accurate, that which is defective. …

What is involuntary is not matter for judgment. But this is twofold, what is done in ignorance, and what is done through necessity. For how will you judge concerning those who are said to sin in involuntary modes? For either one knew not himself, as Cleomenes and Athamas, who were mad; or the thing which he does, as Æschylus, who divulged the mysteries on the stage, who, being tried in the Areopagus, was absolved on his showing that he had not been initiated. …

Mistake is a sin contrary to calculation; and voluntary sin is crime ( ἀδικία ); and crime is voluntary wickedness. Sin, then, is on my part voluntary. Wherefore says the apostle, “Sin shall not have dominion over you; for ye are not under the law, but under grace.” Addressing those who have believed, he says, “For by His stripes we were healed.” Mistake is the involuntary action of another towards me, while a crime ( ἀδικία ) alone is voluntary, whether my act or another’s. These differences of sins are alluded to by the Psalmist, when he calls those blessed whose iniquities ( ἀνομίας ) God hath blotted out, and whose sins ( ἁμαρτίας ) He hath covered. Others He does not impute, and the rest He forgives. For it is written, “Blessed are they whose iniquities are forgiven, whose sins are covered. …

Qui autem a Carpocrate descendunt et Epiphane, censent oportere uxores esse communes; a quibus contra nomen Christi maximum emanavit probruin. Hic autem Epiphanes, cujus etiam scripta feruntur, filius erat Carpocratis, et matris Alexandriæ nomine, ex patre quidera Alexandrinus, ex matre vero Cephalleneus. Vixit autem solum septemdecim annos, et Same, quæ est urbs Cephalleniæ, ut deus est honore affectus. Quo in loco templum ex ingentibus lapidibus, altaria, delubra, museum, ædificatum est et consecratum; et cure est nova luna, convenientes Cephallenei, diem natalem, quo in deos relatus est Epiphanes, sacrificant, libantque, et convivantur, et hymnos canunt. A patre autem didicit et orbem disciplinarum et Platonis philosophiam. Fuit autem princeps monadicæ cognitionis. A quo etiam profluxit hæresis eorum, qui nunc sunt, Carpocratianorum. …

His sic ostensis, age Scripturas, quæ adversantur sophistis hæreticis, jam adducamus, et regulam continentiæ secundum logon seu rationem observandam declaremus. Qui vero intelligit, quæ Scriptura cuique hæresi contraria sit, cam tempestive adhibendo refutabit eos, qui dogmata mandatis contraria fingunt. Atque ut ab alto rem repetamus, lex quidem, sicut prius diximus, illud, “Non concupisces uxorem proximi tui,” prius exclamavit ante conjunctam Domini in Novo Testamento vocem, quæ dicit ex sua ipsius persona: “Audivistis legem præcipientem: Non mœchaberis. Ego autem dico: Non concupisces.” Quod enim vellet lex viros uti moderate uxoribus, et propter solam liberorum susceptionem, ex eo clarum est, quod prohibet quidem eum, qui non habet uxorem, statim cum” captiva” habere consuetudinem. Quod si semel desideraverit, ei, cum tonsa fuerit capillos, permittere ut lugeat triginta diebus. …
