Baring-Gould’s sources: Greek Menaea and Menologies. Authority Mention by Eusebius, H. E. lib. viL c. 29; S. Jerome, ** De Viris Ulustribus”; Peter Diaconus in his letter to S. Fulgentius.] S. Malchion naturally follows after S. Firmilian. The council met at Antioch to decide on the case of Paul of Samosata. S. Firmilian had died on his way to attend it. Helenus of Tarsus, who probably bore to the council the news of his death, presided as the oldest bishop, in the place occupied by Firmilian on the two former occasions. Among the priests present, a certain Malchion, a sophist, made himself noticed by the skill with which he pierced the subtleties of Paul’s discourse, arrested him in his evasions, and brought him to a bald statement of his dogmatic errors. The bishops chose him to conduct the discussion with the incriminated bishop because of his well-known abilities, and the confidence they reposed on him was not disappointed. The notaries took down every word of the discussion, and those acts existed in the time of Eusebius and S. Jerome. All that remain to us are a few fragments preserved by two writers of the 6th century, Leontius of Byzantium and Peter the Deacon.

Paul of Samosata was convicted of error, the council deposed and excommunicated him, and in his room appointed Domnus, son of his predecessor Demetrian, Bishop of Antioch. Before separating, the synod despatched a letter to Dionysius, Bishop of Rome, and Maximus, Bishop of Alexandria, and all other bishops, priests, and deacons, narrating what had been done, and signed by Helenus of Tarsus, Hymenaeus of Jerusalem, Theotecnus of Caesarea, and other bishops, and by Malchion the priest It is not known when Malchion died.
