1 Be ye therefore followers of God, as dear children; 2 And walk in love, as Christ also hath loved us, and hath given himself for us an offering and a sacrifice to God for a sweetsmelling savour. 3 But fornication, and all uncleanness, or covetousness, let it not be once named among you, as becometh saints; 4 Neither filthiness, nor foolish talking, nor jesting, which are not convenient: but rather giving of thanks. 5 For this ye know, that no whoremonger, nor unclean person, nor covetous man, who is an idolater, hath any inheritance in the kingdom of Christ and of God. 6 Let no man deceive you with vain words: for because of these things cometh the wrath of God upon the children of disobedience. 7 Be not ye therefore partakers with them. 8 For ye were sometimes darkness, but now are ye light in the Lord: walk as children of light: 9 (For the fruit of the Spirit is in all goodness and righteousness and truth;) 10 Proving what is acceptable unto the Lord. 11 And have no fellowship with the unfruitful works of darkness, but rather reprove them. 12 For it is a shame even to speak of those things which are done of them in secret. 13 But all things that are reproved are made manifest by the light: for whatsoever doth make manifest is light. 14 Wherefore he saith, Awake thou that sleepest, and arise from the dead, and Christ shall give thee light. 15 See then that ye walk circumspectly, not as fools, but as wise, 16 Redeeming the time, because the days are evil. 17 Wherefore be ye not unwise, but understanding what the will of the Lord is. 18 And be not drunk with wine, wherein is excess; but be filled with the Spirit; 19 Speaking to yourselves in psalms and hymns and spiritual songs, singing and making melody in your heart to the Lord; 20 Giving thanks always for all things unto God and the Father in the name of our Lord Jesus Christ; 21 Submitting yourselves one to another in the fear of God. 22 Wives, submit yourselves unto your own husbands, as unto the Lord. 23 For the husband is the head of the wife, even as Christ is the head of the church: and he is the saviour of the body. 24 Therefore as the church is subject unto Christ, so let the wives be to their own husbands in every thing. 25 Husbands, love your wives, even as Christ also loved the church, and gave himself for it; 26 That he might sanctify and cleanse it with the washing of water by the word, 27 That he might present it to himself a glorious church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish. 28 So ought men to love their wives as their own bodies. He that loveth his wife loveth himself. 29 For no man ever yet hated his own flesh; but nourisheth and cherisheth it, even as the Lord the church: 30 For we are members of his body, of his flesh, and of his bones. 31 For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh. 32 This is a great mystery: but I speak concerning Christ and the church. 33 Nevertheless let every one of you in particular so love his wife even as himself; and the wife see that she reverence her husband.
[AD 407] John Chrysostom on Ephesians 4:32-5:2
The events which are past have greater force than those which are yet to come, and appear to be both more wonderful and more convincing. And hence accordingly Paul founds his exhortation upon the things which have already been done for us, inasmuch as they, on Christ's account, have a greater force. For to say, "Forgive, and you shall be forgiven" [Matthew 6:14], and "if you forgive not, you shall in nowise be forgiven" [Matthew 6:15] — this addressed to men of understanding, and men who believe in the things to come, is of great weight; but Paul appeals to the conscience not by these arguments only, but also by things already done for us. In the former way we may escape punishment, whereas in this latter we may have our share of some positive good. Thou imitatest Christ. This alone is enough to recommend virtue, that it is "to imitate God." This is a higher principle than the other, "for He makes His sun to rise on the evil and the good, and sends rain on the just and the unjust." [Matthew 5:45] Because he does not merely say that we are "imitating God," but that we do so in those things wherein we receive ourselves such benefits. He would have us cherish the tender heart of fathers towards each other. For by heart, here, is meant lovingkindness and compassion. For inasmuch as it cannot be that, being men, we shall avoid either giving pain or suffering it, he does the next thing, he devises a remedy — that we should forgive one another. And yet there is no comparison. For if you indeed should at this moment forgive any one, he will forgive you again in return; whereas to God you have neither given nor forgiven anything. And thou indeed art forgiving a fellow-servant; whereas God is forgiving a servant, and an enemy, and one that hates Him.
"Even as God," says he, "also in Christ forgave you."
And this, moreover, contains a high allusion. Not simply, he would say, has He forgiven us, and at no risk or cost, but at the sacrifice of His Son; for that He might forgive you, He sacrificed the Son; whereas thou, oftentimes, even when you see pardon to be both without risk and without cost, yet dost not grant it.
"Be therefore imitators of God as beloved children; and walk in love, even as Christ also loved you, and gave Himself up for us an offering and sacrifice to God for an odor of a sweet smell."
That you may not then think it an act of necessity, hear how He says, that "He gave Himself up." As your Master loved you, love thou your friend. Nay, but neither will you be able so to love; yet still do so as far as you are able. Oh, what can be more blessed than a sound like this! Tell me of royalty or whatever else you will, there is no comparison. Forgive another, and you are "imitating God," you are made like God. It is more our duty to forgive trespasses than debts of money; for if you forgive debts, you have not "imitated God"; whereas if you shall forgive trespasses, you are "imitating God." And yet how shall you be able to say, "I am poor, and am not able to forgive it," that is, a debt, when you forgive not that which you are able to forgive, that is, a trespass? And surely thou dost not deem that in this case there is any loss. Yea, is it not rather wealth, is it not abundance, is it not a plentiful store?
And behold yet another and a nobler incitement: — "as beloved children," says he. You have yet another cogent reason to imitate Him, not only in that you have received such good at His hands, but also in that you are called His children. And since not all children imitate their fathers, but those which are beloved, therefore he says, "as beloved children."
