Yet not altogether with the fornicators of this world, or with the covetous, or extortioners, or with idolaters; for then must ye needs go out of the world. Limitation of the prohibition, alluded to in 1 Corinthians 5:9. As in dissolute Corinth to 'company with no fornicators,' etc., would be almost to company with none in the (unbelieving) world, ye need not 'altogether' forego contact (cf. 1 Corinthians 10:27). As "fornicators" sin against themselves, so "extortioners" against their neighbours, and "idolaters" against God. The attempt to get "out of the world," in violation of God's will (John 17:15), led to monasticism and its evils.
