Ephesians 5:28-32

In this same way, husbands ought to love their wives as their own bodies. He who loves his wife loves himself. After all, no-one ever hated their own body, but they feed and care for their body, just as Christ does the church – for we are members of his body. ‘For this reason a man will leave his father and mother and be united to his wife, and the two will become one flesh.’ This is a profound mystery – but I am talking about Christ and the church.
