Against the Heathen

Athanasius of Alexandria (circa 296-298) – d. 2 May 373] is also given the titles St. Athanasius the Great, Pope St. Athanasius I of Alexandria, St Athanasius the Confessor and (in the Coptic Orthodox Church, mainly) St Athanasius the Apostolic. He was the 20th bishop of Alexandria. His long episcopate lasted 45 years (c. 8 June 328 - 2 May 373), of which over 17 years were spent in five exiles ordered by four different Roman emperors. He is considered to be a renowned Christian theologian, a Church Father, the chief defender of Orthodoxy against Arianism, and a noted Egyptian leader of the fourth century.

He is remembered for his role in the conflict with Arius and Arianism. In 325, at the age of 27, Athanasius had a leading role against the Arians in the First Council of Nicaea. At the time, he was a deacon and personal secretary of the 19th Bishop of Alexandria, Alexander. Nicaea was convoked by the Emperor Constantine in May–August 325 to address the Arian heresy that Christ is of a distinct substance from the Father.
