Commentary
18 notes on this verseFlee fornication - Abominate, detest, and escape from every kind of uncleanness. Some sins, or solicitations to sin, may be reasoned with; in the above cases, if you parley you are undone; reason not, but Fly! Sinneth against his own body - Though sin of every species has a tendency to destroy life, yet none are so mortal as those to which the apostle refers; they strike immediately at the basis of the constitution. By the just judgment of God, all these irregular and sinful connections are married to death.

Flee from sexual immorality
The command is flight, with no room to reason with the temptation. Most sins use the body as an instrument, while sexual sin makes the body its object. That is why Paul says flee.

The Church Fathers5 voices
If someone hangs himself or kills himself with a dagger, he does not sin against his body but against his soul, on which he inflicts violence. But to fornicate is a sin of the body which touches both the body and the soul.

Gregory said, 'God asks three things of anyone who is baptized: to keep the true faith with all his soul and all his might; to control his tongue; to be chaste in his body.'
And therefore the Apostle says: Flee from fornication; so that by a swift flight, we may avoid the cruelty of the raging mistress and be able to escape from her foul service.

Note that Paul did not say that we should hate immorality, but that we should shun it as people who are aware of the perniciousness of evil.
"Every sin which a human being may have committed is extraneous to the body; but whoever fornicateth, sinneth against his own body." And, for fear you should fly to that statement for a licence to fornication, on the ground that you will be sinning against a thing which is yours, not the Lord's, he takes you away from yourself, and awards you, according to his previous disposition, to Christ: "And ye are not your own; "immediately opposing (thereto), "for bought ye are with a price"-the blood, to wit, of the Lord: "glorify and extol the Lord in your body.

Or if he appoints himself a searcher and judge of the heart and reins, let him in all cases judge equally. And as he knows that it is written, "Behold, thou art made whole; sin no more, lest a worse thing happen unto thee," let him separate the fraudulent and adulterers from his side and from his company, since the case of an adulterer is by far both graver and worse than that of one who has taken a certificate, because the latter has sinned by necessity, the former by free will: the latter, thinking that it is sufficient for him that he has not sacrificed, has been deceived by an error; the former, a violator of the matrimonial tie of another, or entering a brothel, into the sink and filthy gulf of the common people, has befouled by detestable impurity a sanctified body and God's temple, as says the apostle: "Every sin that a man doeth is without the body, but he that committeth fornication sinneth against his own body." And yet to these persons themselves repentance is granted, and the hope of lamenting and atoning is left, according to the saying of the same apostle: "I fear lest, when I come to you, I shall bewail many of those who have sinned already, and have not repented of the uncleanness, and fornication, and lasciviousness which they have committed."

That the sin of fornication is grievous. In the first Epistle of Paul to the Corinthians: "Every sin whatsoever a man doeth is outside the body; but he who committeth fornication sinneth against his own body. Ye are not your own, for ye are bought with a great price. Glorify and bear the Lord in your body."
"Flee fornication." He said not, "abstain from fornication," but "Flee:" that is, with all zeal make to yourselves deliverance from that evil. "Every sin that a man doeth is without the body; but he that committeth fornication sinneth against his own body." This is less than what went before; but since he had to speak of fornicators, he amplifies that guilt by topics drawn from all quarters, from greater things and smaller alike, making the charge heinous. And, in fact, that former topic was addressed to the more religious, but this to the weaker sort. For this also is characteristic of the wisdom of Paul, not only to allege the great things wherewith to abash men, but the lesser also, and the consideration of what is disgraceful and unseemly. "What then," say you, "does not the murderer stain his hand? What, of the covetous person and the extortioner?" I suppose it is plain to every one. But since it was not possible to mention anything worse than the fornicator, he amplifies the crime in another way, by saying that in the fornicator the entire body becomes defiled. For it is as polluted as if it had fallen into a vessel of filth, and been immersed in defilement. And this too is our way. For from covetousness and extortion no one would make haste to go into a bath, but as if nothing had happened returns to his house. Whereas from intercourse with a harlot, as having become altogether unclean, he goes to a bath. To such a degree does the conscience retain from this sin a kind of sense of unusual shame. Both however are bad, both covetousness and fornication; and both cast into hell. But as Paul doeth every thing with good management, so by whatever topics he had he magnified the sin of fornication.

Then when he says, Flee fornication, he presents a third reason, which is taken from the body's contamination. First, he presents the conclusion, saying, Flee fornication. Here it should be noted that other vices are overcome by resisting, because the more a man considers and …
He prescribes to flee from fornication as from a kind of persecutor, from whom we cannot be safe for even a single moment, and to strain every effort to abstain from it. Fornication, he says, defiles the entire body, which is why those who have …

Every sin that a man commits against his neighbour terminates upon an object out of himself, and does not so immediately pollute his body, though it does his soul. But he that committeth fornication, sinneth against his own body - Pollutes, dishonours, and degrades it to a level with brute beasts.
He casts vile reproach on what he Redeemer has dignifies to the last degree by taking it into union with himself. Note, We should not make our present vile bodies more vile by sinning against them. The fifth argument against this sin is that the bodies of Christians are the temples of the Holy Ghost which is in them, and which they have of God,
Direct the eyes and mind to other things and thoughts." Alia vitia pugnando, sola libido fugiendo vincitur--Other vices may be conquered in fight, this only by flight; so speak many of the fathers. A fourth argument is that it is a sin against our own bodies. Every sin that a man does is without the body; he that committeth fornication sinneth against his own body (

Flee--The only safety in such temptations is flight (Ge 39:12; Every sin--The Greek is forcible. "Every sin whatsoever that a man doeth." Every other sin; even gluttony, drunkenness, and self-murder are "without," that is, comparatively external to the body (Mr 7:18; compare Pr 6:30-32).

Flee fornication - A solemn command of God - as explicit as any that thundered from Mount Sinai. None can disregard it with impunity - none can violate it without being exposed to the awful vengeance of the Almighty. There is force and emphasis in the word “flee” φεύγατε pheugate. Man should escape from it; he should not stay to reason about it; to debate the matter; or even to contend with his propensities, and to try the strength of his virtue. There are some sins which a man can resist; some about which he can reason without danger of pollution. But this is a sin where a man is safe only when he flies; free from pollution only when he refuses to entertain a thought of it; secure when he seeks a victory by flight, and a conquest by retreat. Let a man turn away from it without reflection on it and he is safe. Let him think, and reason, and he may be ruined. “The very passage of an impure thought through the mind leaves pollution behind it.” An argument on the subject often leaves pollution; a description ruins; and even the presentation of motives against it may often fix the mind with dangerous inclination on the crime. There is no way of avoiding the pollution but in the manner prescribed by Paul; there is no man safe who will not follow his direction. How many a young man would be saved from poverty, want, disease, curses, tears, and hell, could these two words be made to blaze before him like the writing before the astonished eyes of Belshazzar Dan. 5, and could they terrify him from even the momentary contemplation of the crime. Every sin ... - This is to be taken comparatively. Sins in general; the common sins which people commit do not immediately and directly affect the body, or waste its energies, and destroy life. Such is the case with falsehood, theft, malice, dishonesty, pride, ambition, etc. […]
