Ephesians 5:29-32

for no one ever hated his own flesh, but nourishes and cherishes it, just as Christ also does the church, because we are members of His body. FOR THIS REASON A MAN SHALL LEAVE HIS FATHER AND MOTHER AND SHALL BE JOINED TO HIS WIFE, AND THE TWO SHALL BECOME ONE FLESH. This mystery is great; but I am speaking with reference to Christ and the church.
