Eulogius (4) , bp. of Edessa. When a presbyter there he suffered in the persecution by Valens. Barses the bishop having been deposed and exiled, the orthodox refused to communicate with an Arian prelate, intruded into the see. Modestus the prefect commanded the leading ecclesiastics to obey the emperor and communicate with the new prelate. The whole body, led by Eulogius, offered so firm a resistance that Modestus sentenced them, 80 in number, to transportation to Thrace. The confessors received so much honour there that Valens relegated them, two and two, to distant localities, Eulogius with a presbyter Protogenes being sent to Antinous in the Thebaid. Though there was a Catholic bishop here the population was almost entirely pagan, and the two presbyters commenced missionary work among them. On the cessation of the persecution Eulogius and Protogenes returned to Edessa, where, Barses being dead, Eulogius was consecrated bishop by Eusebius of Samosata (Theod. H. E. iv. 18, v. 4). He attended the councils held at Rome in 369 (Labbe, ii. 894), Antioch in 379, and Constantinople in 381 ( ib. 955). See Soz. vi. 34; and Migne's note 61, Patr. Gk. lxvii. 1394.
