What is it that we Christians affirm when we sing and recite and pray to the true and living God who is Father, Son, and Holy Spirit? One God, yet a Godhead of three; three Persons, yet one God—how did we arrive at this understanding? Is it truly the teaching of Scripture, and must we believe this same truth today? Why did the church insist so early that we hold this doctrine of God? Does it have any impact upon our larger theological understanding? Further, does it matter in terms of our own lives of faith and worship and prayer?
