1 Corinthians 5:1

He accuses everyone in general, so that they would not give themselves over to carelessness, considering themselves free from this sin, but on the contrary, would endeavor to correct it, as a common disgrace. And he did not say: is shamelessly committed, but: "it is …

Fornication - The original word implies criminal conversation of any kind whatever. His father's wife - While his father was alive.

It was told in all places, to their dishonour, and the reproach of Christians. And it was the more reproachful because it could not be denied. Note, The heinous sins of professed Christians are quickly noted and noised abroad.

It is reported commonly that there is fornication among you,.... The apostle having reproved the Corinthians for their schisms and divisions about their ministers, proceeds to charge them with immoralities committed among them, and which were connived at, and took no notice of by them; and particularly a very notorious one, which he here mentions with its aggravated circumstances.

It is reported - Greek It is heard. There is a rumor. That rumor had been brought to Paul, probably by the members of the family of Chloe, 1Co 1:11. Commonly - Ὅλως Holōs. Everywhere. It is a matter of common fame. It is so public that it cannot be concealed; and so certain that it cannot be denied.

She was perhaps a heathen, for which reason he does not direct his rebuke against her (compare 1Co 5:12, 13). ALFORD thinks "have" means have in marriage: but the connection is called "fornication," and neither Christian nor Gentile law would have sanctioned such a marriage, however Corinth's notorious profligacy might wink at the concubinage.

There is fornication among you - The word πορνεια, which we translate fornication in this place, must be understood in its utmost latitude of meaning, as implying all kinds of impurity; for, that the Corinthians were notoriously guilty of every species of irregularity and debauch, we have already seen; and it is not likely that in speaking on this subject, in reference to a people so very notorious, he would refer to only one species of impurity, and that not the most flagitious. That one should have his father’s wife - Commentators and critics have found great difficulties in this statement. One part of the case is sufficiently clear, that a man who professed Christianity had illegal connections with his father’s wife; but the principal question is, was his father alive or dead? Most think that the father was alive, and imagine that to this the apostle refers, 2Co 7:12, where, speaking of the person who did the wrong, he introduces also him who had suffered the wrong; which must mean the father and the father then alive. After all that has been said on this subject, I think it most natural to conclude that the person in question had married the wife of his deceased father, not his own mother, but stepmother, then a widow. This was a crime which the text says was not so much as named among the Gentiles; the apostle must only mean that it was not accredited by them, for it certainly did often occur: but by their best writers who notice it, it was branded as superlatively infamous. Cicero styles it, scelus incredibile et inauditum, an incredible and unheard of wickedness; but it was heard of and practised; and there are several stories of this kind in heathen authors, but they reprobate not commend it. The word ονομαζεται, named, is wanting in almost every MS. and version of importance, and certainly makes no part of the text. […]
