Why Does the Trinity Matter? (Part 2)

READ : John 15:22-27

I will send to you from the Father, the Spirit of truth. (v. 26, NIV)

Knowing God as Trinity yields insights of which unitarian concepts of God have no idea. For example, the greatest of the church fathers, St. Augustine (A.D. 354-430), explained in his monumental work On the Trinity that only a God who has plurality within unity can adequately account for the fact that God is love. If God is a single solitary person, then before the Creation he had no one to love. But God did not have to create anything or anyone in order to love. He has all he needs in himself.

The doctrine of the Trinity has great practical implications. Far from being speculative or empty theorizing, it is wonderfully relevant to our daily lives. Because we are created in the image of the fully relational triune God, concepts such as love, family, and community take on a new dimension of meaning and value. Redeemed by Christ so we can love and be loved – this is what it means to share the life of God.

The Christian gospel of redemption springs from first to last directly out of the triune nature of God. As theologian Bruce Milne notes: “Just about everything that matters in Christianity hangs on the truth of God’s three-in-oneness.”


We love and adore thee: Father, Son, and Holy Spirit.
