Charles Hodge on Ephesians 5:22

V. 22. Wives, submit yourselves to your own husbands, as unto the Lord. The general duty of mutual submission includes the specific duty of wives to be subject to their husbands, and this leads the apostle to speak of the relative duties of husbands and wives. And as the marriage relation is analogous to the relation. between Christ and his church, he is thus led to illustrate the one by the other. As the relation is the same, the duties flowing from it are the same; obedience on the part of the wife, and love on the part of the husband. The apostle teaches the nature, the ground, and the extent of the obedience due from the wife to the husband.

As to the nature of it, it is religious. It is ὡς τῷ Κυρίῳ, as to the Lord. The ὡς, as, does not express similarity, as though the obedience of the wife to her husband was to be as devout and as unconditional as that which she is bound to render to the Lord. But her obedience to her husband is to be regarded as part of her obedience to the Lord. See 6, 5. 6. It terminates on him, and therefore is religious, because determined by religious motives and directed towards the object of the religious affections. This makes the burden light and the yoke easy. For every service which the believer renders to Christ, is rendered with alacrity and joy.
