All of this presupposes something that sets biblical-Christian metaphysics radically apart from other belief systems about ultimate reality. Tresmontant stated it most concisely: “Christianity is a metaphysic of love." This is something speculative reason alone cannot know about ultimate reality—that its very being is love. And this is the reason behind and Within God’s self-limitations, self-determinations, and self—actualizations: God’s being as being-for-others. Does that mean, then, that God must create to have “others” to love? Not at all. The Christian doctrine of the Trinity, itself rooted in biblical narrative, even necessitated by it, means that God’s creative activity, including his self-limitations in relation to creatures, is a free expression of the fullness of the love between Father, Son, and Holy Spirit in eternity. If God were not triune, however, then creation would be necessary for God insofar as God is conceived as love.—The Essentials of Christian Thought 169 (emphasis original)
