Who is the God of the Bible? From both within the church and outside her walls the orthodox doctrine of the Holy Trinity, declared in Scripture and passed down in ecumenical creeds and local confessions of faith, is under attack. The emerging absence of a Trinitarian mind-set so prevalent in the church today has enormous implications for the future of the Christian faith. Concerned to counter contemporary attacks on the doctrine of God, Peter Toon here demonstrates the existence and priority of a Trinitarian pattern in Scripture and defends the essential role of the Trinity in Christian belief, faith, and practice.
