Chapter LXXXIII.

Samuel, 2719 presbyter of the church at Edessa, is said to have written many things in Syriac against the enemies of the church, especially against the Nestorians, the Eutychians and the Timotheans, new heresies all, but differing from one another. On this account he frequently speaks of the triple beast, while he briefly refutes by the opinion of the church, and the authority of Holy Scriptures, showing to the Nestorians, that the Son was God in man, not simply man born of a Virgin, to the Eutychians, that he had true human flesh, taken on by God, and not merely a body made of thick air, or shown from Heaven; to the Timotheans, that the Word was made flesh in such wise, that the Word remains Word in substance, and, human nature remaining human nature, one person of the Son of God is produced by union, not by mingling. He is said to be still living at Constantinople, for at the beginning of the reign of Anthemius, I knew his writings, and knew that he was in the land of the living.
