For the husband is the head of the wife - see the notes on 1 Corinthians 11:3.
As Christ is the head of the church - As Christ rules over the church, and has a right to direct and control it.
And he is the Saviour of the body - That is, of the church, represented as “his body;” see notes, Ephesians 1:23. The idea here seems to be, that as Christ gave himself to save his body, the church; as he practiced self-denial and made it an object of intense solicitude to preserve that church, so ought the husband to manifest a similar solicitude to make his wife happy, and to save her from want, affliction, and pain. He ought to regard himself as her natural protector; as bound to anticipate and provide for her needs; as under obligation to comfort her in trial, even as Christ does the church. What a beautiful illustration of the spirit which a husband should manifest is the care which Christ has shown for his “bride,” the church! See the notes on Ephesians 5:25-29.
