1 Corinthians 5:10

“Yet not altogether with the fornicators of this world, etc.] By “the fornicators of this world” are meant, such as were guilty of this sin, who were the men of the world, mere worldly carnal men, who were never called out of it, or ever professed to be; in distinction from those that were in the church, that had committed this iniquity; and the apostle’s sense is, that his former prohibition of keeping company with fornicators was not to be understood as referring to such persons as were, out of the church, as if no sort of civil conversation and commerce were to be had with men of such, and the like infamous characters; or with the covetous, or extortioners, or with idolaters: that is, of…”

“Limitation of the prohibition alluded to in Co1 5:9. As in dissolute Corinth to "company with no fornicators," &c., would be almost to company with none in the (unbelieving) world; ye need not utterly ("altogether") forego intercourse with fornicators, &c., of the unbelieving world (compare Co1 10:27; Joh 17:15; Jo1 5:18-19). As "fornicators" sin against themselves, so "extortioners" against their neighbors, and "idolaters" against God. The attempt to get "out of the world," in violation of God's will that believers should remain in it but keep themselves from its evil, led to monasticism and its consequent evils.”

“Yet not altogether ... - In my direction not “to company” with them, I did not mean that you should refuse all kinds of contact with them; that you should not treat them with civility, or be engaged with them in any of the transactions of life, or in the ordinary contact of society between man and man, for this would be impossible - but that you should not so associate with them as to be esteemed to belong to them, or so as to be corrupted by their example. You are not to make them companions and friends. With the fornicators - Most pagans were of this description, and particularly at Corinth. See the introduction to this Epistle. Of this world - Of those who are out of the church; or who…”

“But I did not mean that you should altogether refrain from conversing with heathens, though they are guilty in some of these respects. Covetous, rapacious, idolaters - Sinners against themselves, their neighbour, God. For then ye must go out of the world - Then all civil commerce must cease. So that going out of the world, which some account a perfection, St. Paul accounts an utter absurdity. 1 Corinthians 5:11”

“5:10 Paul generally encouraged believers not to separate themselves from the company of sinful unbelievers (e.g., 10:27).”

“altogether: Co1 10:27 of this: Co1 1:20; Joh 8:23, Joh 15:19, Joh 17:6, Joh 17:9, Joh 17:15, Joh 17:16; Co2 4:4; Eph 2:2; Jo1 4:5, Jo1 4:7 for: Mat 5:14-16; Joh 17:15; Phi 2:15; Jo1 5:19; Rev 12:9 1 Corinthians 5:11”
