The unique way Christians talk about God is found in ancient language. We say God is a Holy Trinity. We believe the one true living God, the creator God, the God of Abraham, Issac, and Jacob has been revealed in three distinct persons: the Father, the Son, and the Holy Spirit. We believe in one God, one divine essence and substance in three persons. The doctrine of the Trinity is important and essential because it tells us who God is and subsequently who we are.
