St Athanasius was born in the year 295. He studied the classics and theology in Alexandria, Egypt. He became a Deacon, secretary, and student of bishop Alexander of Alexandria.
When he attended the Council of Nicea in 325 he fought for the defeat of Arianism and acceptance of the divinity of Jesus. To help understand the term begotten of the Father, he formulated the doctrine of homo-ousianism which says that Christ is the same substance as the Father; Arianism taught that Christ was different from and a creation of the Father, a creature and not part of God.
He was Bishop of Alexandria c.328 and served for 46 years. When the dispute over Arianism spilled over from theology to politics, Athanasius was exiled five times, spending more than a third of his episcopate in exile.
He was the biographer of Saint Anthony the Abbot and Saint Potamon of Heraclea. As a confessor of the faith and Doctor of the Church, he fought for the acceptance of the Nicene Creed. He died May 2, 373 in Alexander, Egypt of natural causes.
St. Athanasius pray for us.
May the Lord bless you in the name of the Father and of the Son and of the Holy Spirit. Amen
