1.) Love and the Trinity – God is love (1 John 4:8). Since love, by its very nature, requires both a subject and an object, we can conclude that God, though a single, personal being and thus having a single nature, is in fact a unified plurality of Lover-Beloved. And since the attributes of God are in fact descriptions of the super-personal nature of God himself (this is classic doctrine of divine simplicity), we can conclude that the Love that exists between the Lover and Beloved is itself a person within the unified plurality of God—Lover (the Father), Beloved (the Son), and Love (the Holy Spirit): a self-existent Trinity.
2.) Love and Creation - In love, God created all that is. Nothing outside himself compelled him to create it; he freely chose to create it in order to allow the eternal love of the Trinity to overflow into the lives of other beings also capable of love. Love, as experience has taught us, is, in its highest form, exclusive (that is to say, there cannot be another Beloved than the one Beloved), but at the same time it is outwardly, overflowingly joyful—it seeks to welcome all those around it into the joy of the Love that exists between the Lover and Beloved. As such, we were created in order that we might drink in full the joy of the Trinity’s endless love.
