Book excerpt: First published in 1988, The Search for the Christian Doctrine of God is still considered by many scholars to be the finest work on the Arian Controversy. Examining scholarly works on the Controversy and many original texts, Professor Hanson, provides a clear understanding of how the traditional and historic doctrine of God as the Holy Trinity reached its most mature and enduring form. The author is not primarily concerned to defend the orthodox position itself, but rather to discover and examine the formation of that orthodoxy. The history of the events - the Councils, the interventions of the Emperor, the rivalries of sees, the behaviour of bishops, the varying fortunes of the different schools of thought and their leaders - is interwoven with the progression of thought and doctrine during the sixty years of the Controversy. Professor Hanson sees the problem of the reconciliation of two concepts which were both part of the very fabric of Christianity - monotheism and the worship of Jesus Christ as divine.
