"But fornication, and all uncleanness, or covetousness, let it not even be named among you, as becometh saints."
5. In naming uncleanness in addition to fornication, the reference is to all sensual affections in distinction from wedded love. They are too unsavory for him to mention by name, though in Romans 1, 24 he finds it expedient to speak of them without disguise. However, also wedded love must be characterized by moderation among Christians. While there is a conjugal duty to be required by necessity, it is for the very purpose of avoiding unchastity and uncleanness. The ideal and perfect condition, it is true, would be cohabitation with a sole view to procreation; however, that is too high for attainment by all.
6. Paul declares that the sin he indicates should not be named of the Ephesians. Unquestionably, among Christians there will always be some infirm one to fall; but we must labor diligently, correcting, amending and restraining. We must not suffer the offense to go unchallenged, but curtail and remedy it, lest, as remarked in the preceding lesson, the heathen stumble, saying: "Christians tolerate such vices among themselves; their conduct is not different from our own." An occasional fall among Christians must be borne with so long as right prevails in general, and such things are neither tolerated nor taught, but reproved and amended. Paul gives the counsel (Gal 6, 1) that the brethren restore the fallen in a spirit of meekness; and he blames the Corinthians for not reproving them who sin. 1 Cor 5, 2. A sin, once punished, is as if the sin did not exist; it is no longer a matter of reproach.
7. Likewise with covetousness: we are to understand that it is not to be named of Christians. That is, should one be covetous, should one defraud another or contend with him about temporal advantage, as evidently was true of the Corinthians (1 Cor 6, 1), the offense must not be suffered to go unreproved and uncorrected. The Gospel must be carefully upheld and preserved among the multitude, "that our ministration be not blamed." 2 Cor 6, 3.
I make this point for the sake of those who, so soon as they observe that all Christians are not perfectly holy, but will occasionally stumble and fall, imagine there is no such thing as a Christian and the Gospel is impotent and fruitless. Just as if to be a Christian meant the mountain already climbed and complete, triumphant victory over sin! The fact is, it is rather a contest, a battle. Wherever there is a contest, or a battle, some of the combatants will flee, some will be wounded, some will fall and some even be slain. For warfare is not unaccompanied by disaster if it be real warfare.
8. The writer of the epistle goes on to assign the reason why it does not sound well to hear such things concerning Christians—because they are saints and it behooves saints to be chaste and moderate, and to practice and teach these virtues. Note, he calls Christians "saints," notwithstanding that in this life they are clothed with sinful flesh and blood. Doubtless the term is not applied in consequence of their good works, but because of the holy blood of Christ. For Paul says (1 Cor 6, 11): "But ye were washed, but ye were sanctified, but ye were justified in the name of the Lord Jesus Christ, and in the Spirit of our God." Being holy, we should manifest our holiness by our deeds. Though we are still weak, yet we ought duly to strive to become chaste and free from covetousness, to the glory and honor of God and the edifying of unbelievers.
"Nor filthiness, nor foolish talking, or jesting, which are not befitting."
9. "Filthiness"—scandalous talk—is unchaste language suggestive of fornication, uncleanness and carnal sins. It is common in taverns and generally found as accompaniment of gluttony, drunkenness and gambling. Especially were the Greeks frivolous and adepts in this respect, as their poets and other writers attest. What Paul refers to in particular is the lewd conversation uttered in public without fear and self-restraint. This will excite wicked thoughts and give rise to serious offenses, especially with the young. As he states elsewhere (1 Cor 15, 33), "Evil companionships [communications] corrupt good morals." Should there be any Christians forgetful enough to so transgress, the offense must be reproved; otherwise it will become general and give the congregation an ill repute, as if Christians taught and tolerated it the same as the heathen.
