(Saint) Bishop (March 21) (4th century) An Egyptian monk, later Bishop of Thumuis, who took part (A.D. 347) in the Council of Sardica, and in his time strenuously upheld the Catholic Faith against the Arians. He may have survived another twenty years after the Council. He was associated both with Saint Athanasius and Saint Antony. Saint Jerome also makes mention of him. He was a learned man and wrote several works, of which by far the most important is his “Liturgy,” discovered in our own time, and first published A.D. 1899.
