In this significant work, Professor T.F. Torrance examines the importance of the Nicene Faith for Christian Theology. By cutting across the divide between East and West and between the Catholic and Evangelical, he also offers a unique contribution to our understanding of the doctrine of the Holy Trinity. The author provides an account of the principal themes of the Nicene-Constantinopolitan Creed; the doctrine of God, as Father and Creator, the doctrine of the Holy Spirit and of the Church; and the doctrine of the Holy Trinity. He allows the patristic theologians so speak for themselves and brings to light the inner theological connections which give coherent structure to the classical theology of the ancient Catholic Church as it was formulated during the fourth century. T.F. Torrance engages with the theologians of the fourth century, illuminating and developing the one authentically ecumenical confession of faith of the churches of East and West. In the realisation of this approach, the theology of T.F. Torrance himself, one of our greatest contemporary theologians, is itself illuminated and developed, creating what is truly a remarkable ’one volume dogmatics’ of today. The Very Reverend T.F. Torrance was Professor of Systematic Theology at the University of Edinburgh.
