"Therefore as the church is subject unto
Christ, so let the wives be to their own
husbands in every thing.
Husbands, love your wives, even as Christ
also loved the church, and gave himself for it;
That he might sanctify and cleanse it with the
washing of water by the word,
That he might present it to himself a glorious
church, not having spot, or wrinkle, or any
such thing; but that it should be holy and
without blemish.
So ought men to love their wives as their
own bodies. He that loveth his wife loveth
himself.
For no man ever yet hated his own flesh;
but nourisheth and cherisheth it, even as
the Lord the church:
For we are members of his body, of his
flesh, and of his bones.
31 For this cause shall a man leave his
father and mother, and shall be joined
unto his wife, and they two shall be one
flesh.
This is a great mystery: but I speak
concerning Christ and the church."
Ephesians 5:24-32

Paul was speaking of human marriage,
but he also was referring to Christ and
His Bride, the Church.
