5. Reader at (A. D. 390), then the Bishop of Melitene (A. D. 431).
He wrote A. D. 431, against Nestorius. His zeal led him to use expressions, apparently savouring of the contrary heresy, which, for a time, prejudiced the emperor Theodosius II. against St. Cyril.
He was present at the Oecumenical Council of Ephesus A. D. 431, and constantly maintained its authority.
There remain of his productions a Homily (in Greek) delivered at the Council, (see Conciliorum Nova Collectio à Mansi,
vol. v. p. 181,) and a letter written after it to St. Cyril, which we have in a Latin translation. (Ibid.
pp. 860, 998.)
