One in whom that love is present loves what the other thinks and what the other wills, and so also loves to think in the same way and to will the same things as the other does, consequently to be united to the other and become so to speak one human being. This is what is meant by the Lord's words in Matthew,

And the two will become one flesh; therefore they are no longer two, but one flesh. Matthew 19:4-6; Genesis 2:23-24.
