Imitators of God ( μιμητα του θεου ). This old word from  μιμεομα Paul boldly uses. If we are to be like God, we must imitate him.

An offering and a sacrifice to God ( προσφοραν κα θυσιαν τω θεω ). Accusative in apposition with  εαυτον (himself). Christ's death was an offering to God "in our behalf" ( υπερ ημων ) not an offering to the devil (Anselm), a ransom ( λυτρον ) as Christ himself said (Mt 20:28), Christ's own view of his atoning death.

For an odour of a sweet smell ( εις οσμην ευωδιας ). Same words in Php 4:18 from Le 4:31 (of the expiatory offering). Paul often presents Christ's death as a propitiation (Ro 3:25) as in 1Jo 2:2.

Or covetousness ( η πλεονεξια ). In bad company surely. Debasing like sensuality.

As becometh saints ( καθως πρεπε αγιοις ). It is "unbecoming" for a saint to be sensual or covetous.

Filthiness ( αισχροτης ). Old word from  αισχρος (base), here alone in N.T.

Foolish talking ( μωρολογια ). Late word from  μωρολογος ( μωροσ, λογος ), only here in N.T.

Jesting ( ευτραπελια ). Old word from  ευτραπελος ( ευ, τρεπω, to turn) nimbleness of wit, quickness in making repartee (so in Plato and Plutarch), but in low sense as here ribaldry, scurrility, only here in N.T. All of these disapproved vices are  απαξ λεγομενα in the N.T.

Which are not befitting ( α ουκ ανηκεν ). Same idiom (imperfect with word of propriety about the present) in Col 3:18. Late MSS. read  τα ουκ ανηκοντα like  τα μη καθηκοντα in Ro 1:28.

Ye know of a surety ( ιστε γινωσκοντες ). The correct text has  ιστε, not  εστε. It is the same form for present indicative (second person plural) and imperative, probably indicative here, "ye know." But why  γινωσκοντες added? Probably, "ye know recognizing by your own experience."

No ( πασ--ου ). Common idiom in the N.T. like the Hebrew= oudeis (Robertson, Grammar, p. 732).

Covetous man ( πλεονεκτησ, πλεον εχω ). Old word, in N.T. only here and 1Co 5:10f.; 6:10.

Which is ( ο εστιν ). So Aleph B. A D K L have  ος (who), but  ο is right. See Col 3:14 for this use of  ο (which thing is). On  ειδωλολατρης (idolater) see 1Co 5:10f.

In the Kingdom of Christ and God ( εν τη βασιλεια του Χριστου κα θεου ). Certainly the same kingdom and Paul may here mean to affirm the deity of Christ by the use of the one article with  Χριστου κα θεου. But Sharp's rule cannot be insisted on here because  θεος is often definite without the article like a proper name. Paul did teach the deity of Christ and may do it here.

With empty words ( κενοις λογοις ). Instrumental case. Probably Paul has in mind the same Gnostic praters as in Col 2:4f. See 2:2.

Partakers with them ( συνμετοχο αυτων ). Late double compound, only here in N.T., joint ( συν ) shares with ( μετοχο ) them ( αυτων ). These Gnostics.

But now light ( νυν δε φως ). Jesus called his disciples the light of the world (Mt 5:14).

The fruit of light ( ο καρπος του φωτος ). Two metaphors (fruit, light) combined. See Ga 5:22 for "the fruit of the Spirit." The late MSS. have "spirit" here in place of "light."

Goodness ( αγαθοσυνη ). Late and rare word from  αγαθος. See 2Th 1:11; Ga 5:22.

Proving ( δοκιμαζοντες ). Testing and so proving.

Have no fellowship with ( μη συνκοινωνειτε ). No partnership with, present imperative with  μη. Followed by associative instrumental case  εργοις (works).

Unfruitful ( ακαρποις ). Same metaphor of verse 9 applied to darkness ( σκοτος ).

Reprove ( ελεγχετε ). Convict by turning the light on the darkness.

In secret ( κρυφη ). Old adverb, only here in N.T. Sin loves the dark.

Even to speak of ( κα λεγειν ). And yet one must sometimes speak out, turn on the light, even if to do so is disgraceful ( αισχρον, like 1Co 11:6).

Are made manifest by the light ( υπο του φωτος φανερουτα ). Turn on the light. Often the preacher is the only man brave enough to turn the light on the private sins of men and women or even those of a community.

Wherefore he saith ( διο λεγε ). Apparently a free adaptation of Isa 26:19; 60:1. The form  αναστα for  αναστηθ (second person singular imperative second aorist active of  ανιστημ ) occurs in Ac 12:7.

Shall shine ( επιφαυσε ). Future active of  επιφαυσκω, a form occurring in Job (Job 25:5; 31:26), a variation of  επιφωσκω. The last line suggests the possibility that we have here the fragment of an early Christian hymn like 1Ti 3:16.

Carefully ( ακριβως ). Aleph B 17 put  ακριβως before  πως (how) instead of  πως ακριβως (how exactly ye walk) as the Textus Receptus has it. On  ακριβως (from  ακριβης ) see Mt 2:8; Lu 1:3.

Unwise ( ασοφο ). Old adjective, only here in N.T.

Redeeming the time ( εξαγοραζομενο τον καιρον ). As in Col 4:5 which see.

Be ye not foolish ( μη γινεσθε αφρονες ). "Stop becoming foolish."

Be not drunken with wine ( μη μεθυσκεσθε οινω ). Present passive imperative of  μεθυσκω, old verb to intoxicate. Forbidden as a habit and to stop it also if guilty. Instrumental case  οινω.

Riot ( ασωτια ). Old word from  ασωτος (adverb  ασωτως in Lu 15:13), in N.T. only here, Tit 1:6; 1Pe 4:4.

But be filled with the Spirit ( αλλα πληρουσθε εν πνευματ ). In contrast to a state of intoxication with wine.

To the Lord ( τω Κυριω ). The Lord Jesus. In Col 3:16 we have  τω θεω (to God) with all these varieties of praise, another proof of the deity of Christ. See Col 3:16 for discussion.

In the name of our Lord Jesus Christ ( εν ονοματ του Κυριου ημων Ιησου Χριστου ). Jesus had told the disciples to use his name in prayer (Joh 16:23f.).

To God, even the Father ( τω θεω κα πατρ ). Rather, "the God and Father."

Subjecting yourselves to one another ( υποτασσομενο αλληλοις ). Present middle participle of  υποτασσω, old military figure to line up under (Col 3:18). The construction here is rather loose, coordinate with the preceding participles of praise and prayer. It is possible to start a new paragraph here and regard  υποτασσομενο as an independent participle like an imperative.

Be in subjection . Not in the Greek text of B and Jerome knew of no MS. with it. K L and most MSS. have  υποτασσεσθε like Col 3:18, while Aleph A P have  υποτασσεσθÂωσαν (let them be subject to). But the case of  ανδρασιν (dative) shows that the verb is understood from verse 21 if not written originally.  Ιδιοις (own) is genuine here, though not in Col 3:18.

As unto the Lord ( ως τω Κυριω ). So here instead of  ως ανηκεν εν Κυριω of Col 3:18.

For the husband is the head of the wife ( οτ ανηρ εστιν κεφαλη της γυναικος ). "For a husband is head of the (his) wife." No article with  ανηρ or  κεφαλη.

As Christ also is the head of the church ( ως κα ο Χριστος κεφαλη της εκκλησιας ). No article with  κεφαλη, "as also Christ is head of the church." This is the comparison, but with a tremendous difference which Paul hastens to add either in an appositional clause or as a separate sentence.

Himself the saviour of the body ( αυτος σωτηρ του σωματος ). He means the church as the body of which Christ is head and Saviour.

But ( αλλα ). Perhaps, "nevertheless," in spite of the difference just noted. Once again the verb  υποτασσω has to be supplied in the principal clause before  τοις ανδρασιν either as indicative ( υποτασσοντα ) or as imperative ( υποτασσεσθωσαν ).

Even as Christ also loved the church ( καθως κα ο Χριστος ηγαπησεν την εκκλησιαν ). This is the wonderful new point not in Col 3:19 that lifts this discussion of the husband's love for his wife to the highest plane.

That he might sanctify it ( ινα αυτην αγιαση ). Purpose clause with  ινα and the first aorist active subjunctive of  αγιαζω. Jesus stated this as his longing and his prayer (Joh 17:17-19). This was the purpose of Christ's death (verse 25).

Having cleansed it ( καθαρισας ). First aorist active participle of  καθαριζω, to cleanse, either simultaneous action or antecedent.

By the washing of water ( τω λουτρω του υδατος ). If  λουτρον only means bath or bathing-place ( =  λουτρον ), then  λουτρω is in the locative. If it can mean bathing or washing, it is in the instrumental case. The usual meaning from Homer to the papyri is the bath or bathing-place, though some examples seem to mean bathing or washing. Salmond doubts if there are any clear instances. The only other N.T. example of  λουτρον is in Tit 3:5. The reference here seems to be to the baptismal bath (immersion) of water, "in the bath of water." See 1Co 6:11 for the bringing together of  απελουσασθε and  ηγιασθητε. Neither there nor here does Paul mean that the cleansing or sanctification took place in the bath save in a symbolic fashion as in Ro 6:4-6. Some think that Paul has also a reference to the bath of the bride before marriage. Still more difficult is the phrase "with the word" ( εν ρηματ ). In Joh 17:17 Jesus connected "truth" with "sanctify." That is possible here, though it may also be connected with  καθαρισας (having cleansed). Some take it to mean the baptismal formula.

That he might present ( ινα παραστηση ). Final clause with  ινα and first aorist active subjunctive of  παριστημ (see Col 1:22 for parallel) as in 2Co 11:2 of presenting the bride to the bridegroom. Note both  αυτος (himself) and  εαυτω (to himself).

Glorious ( ενδοξον ). Used of splendid clothing in Lu 7:25.

Spot ( σπιλος ). Late word, in N.T. only here and 2Pe 2:13, but  σπιλοω, to defile in Jas 3:6; Jude 1:23.

Wrinkle ( ρυτιδα ). Old word from  ρυω, to contract, only here in N.T.

But that it should be holy and without blemish ( αλλ' ινα η αγια κα αμωμος ). Christ's goal for the church, his bride and his body, both negative purity and positive.

Even so ought ( ουτως οφειλουσιν ). As Christ loves the church (his body). And yet some people actually say that Paul in 1Co 7 gives a degrading view of marriage. How can one say that after reading Eph 5:22-33 where the noblest picture of marriage ever drawn is given?

Nourisheth ( εκτρεφε ). Old compound with perfective sense of  εκ (to nourish up to maturity and on). In N.T. only here and 6:4.

Cherisheth ( θαλπε ). Late and rare word, once in a marriage contract in a papyrus. In N.T. only here and 1Th 2:7. Primarily it means to warm (Latin foveo), then to foster with tender care as here.

Even as Christ also ( καθως κα ο Χριστος ). Relative (correlative) adverb pointing back to  ουτως at the beginning of the sentence (verse 28) and repeating the statement in verse 25.

Of his flesh and of his bones ( εκ της σαρκος αυτου κα εκ των οστεων αυτου ). These words are in the Textus Receptus (Authorized Version) supported by D G L P cursives Syriac, etc., though wanting in Aleph A B 17 Bohairic. Certainly not genuine.

For this cause ( αντ τουτου ). "Answering to this" =  ενεκεν τουτου of Ge 2:24, in the sense of  αντ seen in  ανθ' ων (Lu 12:3). This whole verse is a practical quotation and application of the language to Paul's argument here. In Mt 19:5 Jesus quotes Ge 2:24. It seems absurd to make Paul mean Christ here by  ανθρωπος (man) as some commentators do.

This mystery is great ( το μυστηριον τουτο μεγα εστιν ). For the word "mystery" see 1:9. Clearly Paul means to say that the comparison of marriage to the union of Christ and the church is the mystery. He makes that plain by the next words.

But I speak ( εγω δε λεγω ). "Now I mean." Cf. 1Co 7:29; 15:50.

In regard of Christ and of the church ( εις Χριστον κα [εισ] την εκκλησιαν ). "With reference to Christ and the church." That is all that  εις here means.

Nevertheless ( πλην ). "Howbeit," not to dwell unduly (Abbott) on the matter of Christ and the church.

Do ye also severally love ( κα υμεις ο καθ' ενα εκαστος αγαπατω ). An unusual idiom. The verb  αγαπατω (present active imperative) agrees with  εκαστος and so is third singular instead of  αγαπατε (second plural) like  υμεις. The use of  ο καθ' ενα after  υμεις = " ye one by one " and then  εκαστος takes up (individualizes) the "one" in partitive apposition and in the third person.

Let the wife see that she fear ( η γυνη ινα φοβητα ). There is no verb in the Greek for "let see" ( βλεπετω ). For this use of  ινα with the subjunctive as a practical imperative without a principal verb (an elliptical imperative) see Mr 5:23; Mt 20:32; 1Co 7:29; 2Co 8:7; Eph 4:29; 5:33 (Robertson, Grammar, p. 994). "Fear" ( φοβητα, present middle subjunctive) here is "reverence."
