Marriage and The Great Commission.

Ephesians 5:22-32
Wives and Husbands
22Wives, submit to your husbands as to the Lord. 23For the husband is the head of the wife as Christ is the head of the church, his body, of which he is the Saviour. 24Now as the church submits to Christ, so also wives should submit to their husbands in everything.
25Husbands, love your wives, just as Christ loved the church and gave himself up for her 26to make her holy, cleansing her by the washing with water through the word, 27and to present her to himself as a radiant church, without stain or wrinkle or any other blemish, but holy and blameless. 28In this same way, husbands ought to love their wives as their own bodies. He who loves his wife loves himself. 29After all, no one ever hated his own body, but he feeds and cares for it, just as Christ does the church— 30for we are members of his body. 31"For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh." 32This is a profound mystery—but I am talking about Christ and the church.

This has often been interpreted in a very legalistic way. But this is in fact the great commission in other words. The key to this passage is verse 32 where Paul says that he is talking about Christ and The Church.

He is therefore not talking about wives submitting to their husbands and Husbands loving their wives but about The Church submitting to Christ and Christ loving The Church.

The relationship between a husband and wife within Christian marriage mirrors the relationship between Christ and The Church. Therefore when Husbands love their wives the world can see how Christ loves The Church and when wives submit to their husbands the world can see how The Church submits to Christ.

Submission is not the same as subjection. Wives are not subjected to their husbands. The submission is by choice as The Church submits to Christ by choice. It is not a case of one having dominion over another.
As a husband is united with his wife Christ is united with his church and as a husband and wife are one Christ and The Church are one.

So when husbands love their wives the world can see how Christ loves The Church and when wives submit to their husbands the world can see how The Church submits to Christ. Paul is speaking of a way we can do what Saint Francis of Assisi said.

Go and preach the gospel and if you have to, use words.
