Ephesians 5:11

Have no fellowship with the unfruitful works of darkness. — To “have no fellowship” with such works is not to refuse to take part in them (for this surely might be taken for granted), but to keep no terms with them, to have no sympathy or indulgence or excuse for them. So the word is used, in Philippians 4:14, of “communicating with my affliction;” and in Revelation 18:4, of “being partakers with the sins” of Babylon. It is through such weak or cowardly indulgence, more than the actual love of evil, that sin is suffered to prevail. Hence St. Paul adds, “rather reprove them.” Our Lord Himself has declared in all such cases, “He that is not with Me is against Me.”

The unfruitful works of darkness. — St. Paul has a similar antithesis in the Epistle to the Romans (Romans 6:19). They who are in sin “yield their members servants to iniquity unto iniquity.” Iniquity has no result but iniquity; and hence he goes on to ask, “What fruit had ye then in those things of which ye are now ashamed?” This weary fruitlessness is at once the sign and the penalty of sin, so that men have fancied it to be one chief element of the suffering of the lost. But they who are in Christ “yield their members servants to righteousness unto holiness.” “They have,” he says, “their fruit unto holiness” now, and “in the end the everlasting life,” which is everlasting holiness. Similarly, in Galatians 5:20, we have “the works of the flesh,” but “the fruit of the Spirit.” Rarely, indeed, does Scripture speak of “evil fruit” (Matthew 7:17; Matthew 12:33). Generally, “to be unfruitful” is an all-sufficient condemnation. “Every branch that beareth not fruit he taketh away” (John 15:2).

Rather reprove them. — In the word “reprove,” whether in its application to the witness of the Holy Ghost (John 16:8), or to the witness of men (as in 1 Corinthians 14:24; 1 Timothy 5:20; Titus 1:9, et al.), there is described a double function — to “convince,” if it may be, the sinner in himself; to “convict” him, if the other function fails, before men and angels. Both these functions St. Paul urges here. It is not enough to “have no fellowship with them.” To this tacit reproof open reproof in word and deed is to be added; only in such reproof it should be remembered that it would be disgraceful “even to speak” in detail of the actual “things done in secret.”
