Trinity: The God We Don't Know (Belief Matters);

Most people assume they know what they mean when they use the word “God.” They mean a powerful old guy in the sky ready to obliterate us if we do wrong but basically benevolent, if a little senile. The Christian doctrine of the Trinity shows us God is vastly more interesting. God is actually fleshed among us in Jesus, poured out on us in the Holy Spirit’s intoxication of the church. God is three divine persons in perfect harmony and beauty—and God invites us into that unimaginable intimacy. We don’t know this God, but we should. Trinity uses scripture, the Early Church tradition, and some modern theology to argue that God is a mystery whom we can’t understand but who can shape our misunderstanding to allow for faithful living and holy love of God and neighbor.
