Ephesians 5:23, 31-32

For the husband is head of the wife, as Christ is head of the church, Himself being the Savior of the body.

FOR THIS REASON A MAN SHALL LEAVE HIS FATHER AND HIS MOTHER AND SHALL BE JOINED [and be faithfully devoted] TO HIS WIFE, AND THE TWO SHALL BECOME ONE FLESH. [Gen 2:24] This mystery [of two becoming one] is great; but I am speaking with reference to [the relationship of] Christ and the church.
