"We worship one God in Trinity, and Trinity in Unity." (Athanasian Creed, 6th century A.D. The triunity of the Christian God is not just one isolated doctrine among others. Allan Coppedge unfolds the implications of the trinitarian being of God for our entire understanding of the nature, character and acts of God. Building on the theology of the church from the early church fathers, tracing it through the Reformation and down to current theological treatments of the Trinity, Coppedge draws out the implications for our understanding of God's nature, attributes, roles, and relationship to creation and providence.
