1 Corinthians 15:33

But for the rest, let our most beloved brethren firmly decline, and avoid the words and conversations of those whose word creeps onwards like a cancer; as the apostle says, "Evil communications corrupt good manners." And again: "A man that is an heretic, after one admonition, reject: knowing that he that is such is subverted, and sinneth, being condemned of himself." And the Holy Spirit speaks by Solomon, saying, "A perverse man carrieth perdition in his mouth; and in his lips he hideth a fire." Also again, he warneth us, and says, "Hedge in thy ears with thorns, and hearken not to a wicked tongue." And again: "A wicked doer giveth heed to the tongue of the unjust; but a righteous man does not listen to lying lips." And although I know that our brotherhood there, assuredly fortified by your foresight, and besides sufficiently cautious by their own vigilance, cannot be taken nor deceived by the poisons of heretics, and that the teachings and precepts of God prevail with them only in proportion as the fear of God is in them; yet, even although needlessly, either my solicitude or my love persuaded me to write these things to you, that no commerce should be entered into with such; that no banquets nor conferences be entertained with the wicked; but that we should be as much separated from them, as they are deserters from the Church; because it is written, "If he shall neglect to hear the Church, let him be unto thee as a heathen man and a publican." And the blessed apostle not only warns, but also commands us to withdraw from such. "We command you," he says, "in the name of Jesus Christ our Lord, that ye withdraw yourselves from every brother that walketh disorderly, and not after the tradition which he received of us." There can be no fellowship between faith and I faithlessness. […]

Yet let not the excessive and headlong faithlessness of many move or disturb us, but rather strengthen our faith in the truthfulness which has foretold the matter. As some have become such, because these things were predicted beforehand, so let other brethren beware of matters of a like kind, because these also were predicted beforehand, even as the Lord instructs us, and says, "But take ye heed: behold, I have told you all things." Avoid, I beseech you, brethren, men of this kind, and drive away from your side and from your ears, as if it were the contagion of death, their mischievous conversation; as it is written, "Hedge thine ears about with thorns, and refuse to hear a wicked tongue." And again, "Evil communications corrupt good manners." The Lord teaches and warns us to depart from such. He saith, "They are blind leaders of the blind; and if the blind lead the blind, they shall both fall into the ditch." Such a one is to be turned away from and avoided, whosoever he may be, that is separated from the Church. Such a one is perverted and sins, and is condemned of his own self. Does he think that he has Christ, who acts in opposition to Christ's priests, who separates himself from the company of His clergy and people? He bears arms against the Church, he contends against God's appointment. An enemy of the altar, a rebel against Christ's sacrifice, for the faith faithless, for religion profane, a disobedient servant, an impious son, a hostile brother, despising the bishops, and forsaking God's priests, he dares to set up another altar, to make another prayer with unauthorized words, to profane the truth of the Lord's offering by false sacrifices, and not to know that he who strives against the appointment of God, is punished on account of the daring of his temerity by divine visitation.

That we are to live with the good, but to avoid the evil. In Solomon, in the Proverbs: "Bring not the impious man into the habitation of the righteous." Also in the same, in Ecclesiasticus: "Let righteous men be thy guests." And again: "The faithful friend is a medicine of life and of immortality." Also in the same place: "Be thou far from the man who has the power to slay, and thou shalt not suspect fear." Also in the same place, : "Blessed is he who findeth a true friend, and who speaketh righteousness to the listening ear." Also in the same place: "Hedge thine ears with thorns, and hear not a wicked tongue." Also in the seventeenth Psalm: "With the righteous Thou shalt be justified; and with the innocent man Thou shalt be innocent; and with the froward man Thou shalt be froward." Also in the first Epistle of Paul to the Corinthians: "Evil communications corrupt good dispositions."

"Be not deceived: evil company doth corrupt good manners." Then that he might not make his discourse too rough, he dwells not long upon his "reductio ad absurdum," but again turns his discourse to exhortation, saying, "Be not deceived: evil company doth corrupt good manners." And this he said, both to rebuke them as without understanding, (for here he by a charitable expression, calls "good" that which is easily deceived,) and also, as far as he could, to make some allowance to them for the past with a view to their return, and to remove from them and transfer to others the greater part of his charges, and so by this way also to allure them to repentance. Which he doth likewise in the Epistle to the Galatians, saying, "But he that troubleth you shall bear his judgment, whosoever he be."

He turns his speech to exhortation. Meanwhile he covertly accuses them of foolishness and frivolity; for this is what he expresses by the word: "be not deceived." By "good manners" he means manners that easily yield to deception; he shows at the same time that …

961. – Then when he says: Do not be deceived, he concludes to a warning from the preceding: first, as to the sick; secondly, as to the perfect and just (v. 34). 962. – In regard to the first he does two things: first, he …

Error and vice are infectious: and, if we would avoid the contagion, we must keep clear of those who have taken it. He that walketh with wise men shall be wise; but a companion of fools shall be destroyed, Prov. xiii. Here is an exhortation to break off their sins, and rouse themselves, and lead a more holy and righteous life (

Be not deceived - By such pernicious counsels as this. Evil communications corrupt good manners - He opposes to the Epicurean saying, a well - known verse of the poet Menander. Evil communications - Discourse contrary to faith, hope, or love, naturally tends to destroy all holiness.

He answers an objection against this truth, and takes occasion thence to show what a vast change will be made in the bodies of believers at the resurrection,

Be not deceived - By your false teachers, and by their smooth and plausible arguments. This is an exhortation. He had thus far been engaged in an argument on the subject. He now entreats them to beware lest they be deceived - a danger to which they were very liable from their circumstances.

"Evil communications" refer to intercourse with those who deny the resurrection. Their notion seems to have been that the resurrection is merely spiritual, that sin has its seat solely in the body, and will be left behind when the soul leaves it, if, indeed, the soul survive death at all. good--not only good-natured, but pliant.

Be not deceived - Do not impose on yourselves, and permit not others to do it. Evil communications corrupt good manners - There are many sayings like this among the Greek poets; but this of the apostle, and which according to the best MSS. makes an Iambic verse, is generally supposed to have been taken from Menander’s lost comedy of Thais. Φθειρουσιν ηθη χρησθ’ ὁμιλιαι κακαι· Bad company good morals doth corrupt. There is a proverb much like this among the rabbins: תרי אורי יכישי ותר רטיכא אוקרן יכישי לרטיכא “There were two dry logs of wood, and one green log; but the dry logs burnt up the green log.” There is no difficulty in this saying; he who frequents the company of bad or corrupt men will soon be as they are. He may be sound in the faith, and have the life and power of godliness, and at first frequent their company only for the sake of their pleasing conversation, or their literary accomplishments: and he may think his faith proof against their infidelity; but he will soon find, by means of their glozing speeches, his faith weakened; and when once he gets under the empire of doubt, unbelief will soon prevail; his bad company will corrupt his morals; and the two dry logs will soon burn up the green one. The same sentiment in nearly the same words is found in several of the Greek writers; Aeschylus, Sept. Theb. ver. 605: Εν παντι πραγει δ’ εσθ’ ὁμιλιας κακης κακιον ουδεν· “In every matter there is nothing more deleterious than evil communication.” - Diodorus Siculus, lib. xvi. cap. […]
