Dr. John Rao discusses early Christianity and the Greco-Roman world from Arianism to Post-Nicaean Arianism. This lecture on the Arianist Crisis by Dr. John Rao treats of the indirect way in which men like Eusebius of Nicomedia managed to redeem the heresy and persecute all of the great men who had fought against it at Nicaea. The role of St. Athanasius and of the monks now becomes clear.
