The Nicene Age

Who Didymus the Blind was

Blind from the age of four, Didymus mastered the whole range of learning by ear and memory and headed the Alexandrian catechetical school for half a century — Athanasius’s appointee, Jerome’s and Rufinus’s teacher, and Antony’s admirer (who told him his inner sight was worth more than the eyes flies and gnats also possess). A staunch defender of Nicaea and of the Spirit’s divinity, he wrote On the Holy Spirit (surviving in Jerome’s Latin) and commentaries recovered on papyrus at Tura in 1941. His posthumous condemnation as an Origenist cost him most of his Greek text; his learning and his blindness made him one of the marvels of the age.
