Biography

Who was Athanasius of Alexandria?

Why this Father matters to Catholic apologetics: Athanasius's five exiles are the strongest evidence that the Arian controversy was a genuine theological dispute. He was exiled by emperors who had everything to gain from his compliance. He refused because he understood what was at stake: if the Son is not truly God, the Incarnation is not what Christians claim and salvation is not what the Creed promises.

Athanasius attended the Council of Nicaea in AD 325 as a young deacon and became Bishop of Alexandria at around thirty. For the next forty-five years his episcopate was defined by the struggle to preserve the Nicene definition — that the Son is of the same substance (homoousios) as the Father. He was exiled five times by four different emperors — seventeen years total. His Festal Letter of AD 367 is the first surviving list of the 27-book New Testament canon.
