St Athanasius Plovdiv 16-17 c

St Athanasius took part in the First Ecumenical Council when he was still a deacon. He surpassed everyone there in his zeal to uphold the teaching that Christ is consubstantial (homoousios) with the Father, and not merely a creature, as the Arians proclaimed.
This radiant beacon of Orthodoxy spent most of his life in exile from his See, because of the plotting of his enemies. He returned to his flock as he was approaching the end of his life. Like an evening star, he illumined the Orthodox faithful with his words for a little while, then reposed in 373.
