| Geneva Study Bible {9} I wrote unto you in an epistle not to company with fornicators: (9) Now he speaks more generally: and that which he spoke before of the incestuous person he shows that it pertains to others, who are known to be wicked and those who through their wicked life are a slander to the Church, who ought also by lawful order be cast out of the community of the Church. And making mention of eating meals, either he means that feast of love at which the supper of the Lord was received, or else their common usage and manner of life. And this is to be properly understood, lest any man should think that either matrimony was broken by excommunication, or such duties hindered and cut off by it, as we owe one to another: children to their parents, subjects to their rulers, servants to their masters, and neighbour to neighbour, to win one another to God. People's New Testament 5:9 I wrote unto you in an epistle. He had written an earlier letter which has not been preserved, probably a short one, to which reference is made.

Not to converse - Familiarly; not to contract any intimacy or acquaintance with them, more than is absolutely necessary. Jamieson-Fausset-Brown Bible Commentary 9. I wrote . in an epistle-rather, "in the Epistle": a former one not now extant. That Paul does not refer to the present letter is proved by the fact that no direction "not to company with fornicators" occurs in the previous part of it; also the words, "in an (or, the) epistle," could not have been added if he meant, "I have just written" (2Co 10:10). "His letters" (plural; not applying to merely one) confirm this. 2Co 7:8 also refers to our first Epistle, just as here a former letter is referred to by the same phrase. Paul probably wrote a former brief reply to inquiries of the Corinthians: our first Epistle, as it enters more fully into the same subject, has superseded the former, which the Holy Spirit did not design for the guidance of the Church in general, and which therefore has not been preserved. See my [2285]Introduction. Matthew Henry's Concise Commentary 5:9-13 Christians are to avoid familiar converse with all who disgrace the Christian name. Such are only fit companions for their brethren in sin, and to such company they should be left, whenever it is possible to do so. Alas, that there are many called Christians, whose conversation is more dangerous than that of heathens! |
