probably late third century. The unknown writer of a dialogue, De Recta In Deum Fide (“On the Correct Faith in God”). In the Greek version the author's name is given as “Adamantius who is also Origen.” The [[Cappadocian Fathers]] mistakenly but understandably identified him with the great Alexandrian teacher, but this is impossible as Adamantius draws freely on Methodius who was one of Origen's chief opponents. The dialogue, an anti- Gnostic work in five books, deals with the heresies of Bardesanes* and Marcion.* The Latin translation is the work of Rufinus. Precise dating of the dialogue is impossible, but it can be no later than the end of the Great Persecution in 313.
