God’s love is most perfectly present within the mystery of the three Persons in one God. Each divine Person knows the other two and, on the basis of that knowledge, chooses to give Himself to the other two. This choice is total—i.e., it is permanent and limitless. It is permanent because the Trinity was, is, and always will be. The love of each Person in the Trinity is limitless because each Person gives Himself completely—i.e., each Person gives His very Being, His very life, to the other two. Divine love is therefore identified with life. In God, there are not two realities called love and life, but rather only one: love which is the same as life. It could also be put the other way: in God there is only one reality, life, which is the same as love. The love of God the Father is an example of the permanent and limitless character of divine love. God the Father’s love of the Son and the Holy Spirit is an act of His will founded on a perfect knowledge of the truth about the value and dignity of the Son and the Holy Spirit. God the Father never ceases to love the Son and the Holy Spirit. He would never decide to stop loving the Son and the Holy Spirit. Nor would He ever decide to “leave” the Trinity. Further, the Father’s love of the Son and the Holy Spirit is a total gift, a gift of His very Being. If human persons want to be true to their very selves as beings made in the image and likeness of God, they will love as God loves.
In a sense, Adam could not love without receiving the gift of love from another bodied person—i.e., Eve. In addition, Adam could not love without Eve because his love would not have been life-giving.
