A human has a head with a brain and a body with a heart. If either is dead the person is dead. In Ephesians, Paul explains that, for the purposes of the analogy he is making — AFTER saying that all believers are to submit to one another — the man is the head of the person and the woman is the body. This fits with the idea held at his time that the man was closer to the mind of God and the woman closer to the heart of God . . . it also fits with the belief also held at his time that the heart was the ruling organ of the body and the Jewish belief that women intuitively understand things about God that men need to study to learn.
The human — who was one person until divided into two and then called to be Echad — a word that translates “one” but which is not “singular one” but is more like “one bunch of grapes” or a plural, multi-faceted one. I express it as plural unity because it is the word for the two shall become one AND the word used when Moses says, “Hear, O Israel, the Lord our God, the Lord is One.” Just as Jesus said “I and the father are one” and he explains that he hasn’t do anything the hasn’t seen the Father doing. They function in plural unity.
And that’s important because Paul ends the section of Ephesians 5 with this statement “29 For no one ever hated his own flesh, but nourishes and cherishes it, just as the Lord does the church. 30 For we are members of His body, of His flesh and of His bones. 31 “For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh.” 32 This is a great mystery, but I speak concerning Christ and the church.” (yes, there is one additional verse here but it’s a practical summary moving back from the analogy and it’s been twisted so much that it warrants it’s own discussion)
Jesus loves the church how? By sacrificing, laying down his life, redeeming, and loving us thoroughly! Men — imagine your wives are like your own body — imagine you have literally become one flesh with them. That’s the mystery and that’s the picture — as well as you do this, that’s the picture you are giving to the world about what the relationship between Christ and the Church looks like. Your picture will be imperfect, but that’s what you’re aiming for.
Christ and the Church is NOT the analogy of husband and wife. Husband and wife is the analogy for Christ and the Church
So Christ and the Church is NOT the analogy of husband and wife. Husband and wife is the analogy for Christ and the Church. And just as the church is supposed to strive for plural unity with Christ, that is intended to be expressed to the world when they see husband and wife functioning plural unity — the picture we give is what they will understand. And where we fail we destroy the picture . . . kind of like how Moses struck the rock and destroyed a picture of Messiah and the Jews know they needed and credit with their errors from that point on.
