This Eusebius, who is mentioned with praise by Dionysius of Alexandria, in the epistle quoted in chap. 11, above, was a deacon in the church of Alexandria, who distinguished himself by his good offices during the persecution of Valerian (a.d. 257), as recorded in that epistle, and also during the revolt and siege of Alexandria after the death of Valerian (in 262), as recorded in this chapter. From the account given here we see that he attended the first, or at least one of the earlier councils of Antioch in which the case of Paul was discussed (undoubtedly as the representative of Dionysius, whose age prevented his attending the first one, as mentioned in chap. 27), and the Laodiceans, becoming acquainted with him there, compelled him to accept the bishopric of their church, at that time vacant. As we see from the account of Anatolius’ appointment farther on in this chapter, he died before the meeting of the council which condemned Paul. We know in regard to him only what is told us in these two chapters. The name Eusebius was a very common one in the early Church. The Dict. of Christ. Biog. mentions 137 persons of that name belonging to the first eight centuries.
