Section 02: The Arian Controversy
The doctrinal heart of the St. Athanasius reference guide. This section covers the controversy that defined his episcopate and the fourth-century Church: the teaching of Arius, the Council of Nicaea and its key term homoousios, Athanasius’ great polemical response in the Orations Against the Arians, and the long road from Nicaea (325) to the reconciling Council of Alexandria (362).
Tradition: Pan-Orthodox (Church Father)
