Matthew Poole and continuators on Ephesians 5:23

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 .

Superiour to her by God's Ordination in Authority, and dignity, as the head in the natural body being the seat of reason, and the fountain of sense and motion is more excellent than the rest of the body.

See ch. 1.22. Col. 1.18. The particle as notes not equality but likeness, Christ being the head of the Church in a more excellent way than the Husband is of the Wife.

i. e. Christ is the Saviour of his Church, implying that so likewise the Husband is given to the Wife to be a Saviour to her in maintaining, protecting and defending her, and therefore the Wife if she regard her own good, should not grudge to be subject to him.
