Dr. John Rao discusses early Christianity and the Greco-Roman world from Arianism to Post-Nicaean Arianism. A final discussion of Arianism concerns the work of the Emperor Constantius to replace the decision of Nicaea with an heretical or ambiguous definition of Catholic faith. The Papacy, St. Hilary of Poitiers and the West enter into the story, along with Cappadocian Fathers. Dr. John Rao continues the discussion until the return to Orthodoxy at the second Ecumenical Council in Constantinople.
