Be not deceived: evil companions corrupt good morals.

AD 1637
Evil communications corrupt good manners. Viz, with atheists and unbelievers who deny the resurrection. This is an iambic senarius of Menander"s, as S. Jerome points out.
An enemy of the altar, a rebel against Christ’s sacrifice, a traitor to his faith, a blasphemous renegade, a disobedient servant, an undutiful son, a hostile brother, he scorns the bishops, turns his back on God’s priests and dares to set up another altar, to offer another prayer in unlawful words, to profane the true offering of the Lord with false sacrifices. Does he not know that the presumption which strives against the ordinance of God is punished by the chastisement of God? The Unity of the Church
The Lord teaches and admonishes that we must withdraw from such. “They are blinded guides of the blind. But if the blind man guide a blind man, both shall fall into a pit.” Such a one is to be turned away from, and whoever has separated himself from the church is to be shunned. Such a man is perverted and is condemned by his very self. Does he seem to himself to be with Christ, who acts contrary to the elders of Christ, who separates himself from association with his clergy and his people? That man bears his arms against the church; he fights against God’s plan.
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, "Evil communications corrupt good manners.".
Also in the first Epistle of Paul to the Corinthians: "Evil communications corrupt good dispositions."
Evil communications (or discourses) corrupt good manners. He hints that this error against the resurrection, and the other faults into which they had fallen, were occasioned by the heathen philosophers and other vain teachers among them. (Witham)
You despise gold; someone else loves it. You spurn wealth; he eagerly pursues it. You love silence, weakness and privacy. He takes delight in talking and effrontery in the public square, and streets, and apothecary shops… Do not remain under the same roof with him. Do not rely on your past continence. You cannot be holier than David or wiser than Solomon… If in the course of your clerical duty you have to visit a widow or a virgin, never enter the house alone. Let your companions be persons who will not disgrace you… You must not sit alone with a woman secretly and without witnesses. If she has anything confidential to disclose, she is sure to have some nurse or housekeeper, some virgin, some widow, some married woman. She cannot be so friendless as to have none except you to whom she can venture to confide her secrets.
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 does likewise in the Epistle to the Galatians, saying, But he that troubles you shall bear his judgment, whosoever he be. Galatians 5:10
Paul says this both in order to rebuke their past conduct and to show that he makes some allowance for them, in the hope that they will now repent and return to the right path.
Follow companies and conversations worthy of God, mindful of that short verse, sanctified by the apostle's quotation of it, "Ill interviews good morals do corrupt."
