EUSEBIUS (Gr. Εὐσέβιος, from εὐσεβής, pious, cf. the Latin name Pius), a name borne by a large number of bishops and others in the early ages of the Christian Church. Of these the most important are separately noticed below. No less than 25 saints of this name (sometimes corrupted into Eusoge, Euruge, Usoge, Usuge, Uruge and St Sebis) are venerated in the Roman Catholic Church, of whom 23 are included in the Bollandist Acta Sanctorum; many are obscure martyrs, monks or anchorites, but two deserve at least a passing notice.
Eusebius, bishop of Vercelli (d. 371), is notable not only as a stout opponent of Arianism, but also as having been, with St Augustine, the first Western bishop to unite with his clergy in adopting a strict monastic life after the Eastern model (see Ambrose, Ep. 63 ad Vercellenses, § 66). The legend that he was stoned to death by the Arians was probably invented for the edification of the Orthodox.
Eusebius, bishop of Samosata (d. 380), played a considerable part in the later stages of the Arian controversy in the East. He is first mentioned among the Homoean and Homoeusian bishops who in 363 accepted the Homousian formula at the synod of Antioch presided over by Meletius, with whose views he seems to have identified himself (see [Meletius of Antioch]). According to Theodoret (5, 4, 8) he was killed at Doliche in Syria, where he had gone to consecrate a bishop, by a stone cast by an Arian woman. He thus became a martyr, and found a place in the Catholic calendar (see the article by Loofs in Herzog-Hauck, Realencykl., ed. 1898, v. p. 620).
Eusebius of Laodicea, though not included among the saints, was noted for his saintly life. He was an Alexandrian by birth, and gained so great a reputation for his self-denial and charity that when in 262 the city was besieged by the troops of the emperor Gallienus he obtained permission, together with Anatolius, from their commander Theodotus, to lead out the non-combatants, whom he tended “like a father and physician.” He went with Anatolius to Syria, and took part in the controversy against Paul of Samosata, bishop of Antioch. He became bishop of Laodicea, probably in the following year (263), and died some time before 268. His friend Anatolius succeeded him as bishop in the latter year (see the article by E. Hennecke in Herzog-Hauck, v. 619).
EUSEBIUS, bishop of Rome for four months under the emperor Maxentius, in 309 or 310. The Christians in Rome, divided on the question of the reconciliation of apostates, on which Eusebius held the milder view, brought forward a competitor, Heraclius. Both competitors were expelled by the emperor, Eusebius dying in exile in Sicily. He was buried in the cemetery of St Calixtus at Rome; and the extant epitaph, in eight hexameter lines, set up here by his successor Damasus, contains all the information there is about his life.
EUSEBIUS [of Caesarea] (c. 260-c. 340), ecclesiastical historian, who called himself Eusebius Pamphili, because of his devotion to his friend and teacher Pamphilus, was born probably in Palestine between A.D. 260 and 265, and died as bishop of Caesarea in the year 339 or 340. We know little of his youth beyond the fact that he became associated at an early day with Pamphilus, presbyter of the Church of Caesarea, and founder of a theological school there (see Hist. Eccl. vii. 32). Pamphilus gathered about him a circle of earnest students who devoted themselves especially to the study of the Bible and the transcription of Biblical codices, and also to the defence and spread of the writings of Origen, whom they regarded as their master. Pamphilus had a magnificent library, which Eusebius made diligent use of, and a catalogue of which he published in his lost Life of Pamphilus (Hist. Eccl. vi. 32). In the course of the Diocletian persecution, which broke out in 303, Pamphilus was imprisoned for two years, and finally suffered martyrdom. During the time of his imprisonment (307-309) Eusebius distinguished himself by assiduous devotion to his friend, and assisted him in the preparation of an apology for Origen’s teaching (Hist. Eccl. vi. 33), the first book of which survives in the Latin of Rufinus (printed in Routh’s Reliquiae sacrae, iv. 339 sq., and in Lommatzsch’s edition of Origen’s Works, xxiv. p. 293 sq.). After the death of Pamphilus Eusebius withdrew to Tyre, and later, while the Diocletian persecution was still raging, went to Egypt, where he seems to have been imprisoned, but soon released. He became bishop of Caesarea between 313 and 315, and remained such until his death. The patriarchate of Antioch was offered him in 331, but declined (Vita Constantini, iii. 59 sq.).
Eusebius was a very important figure in the church of his day. He was not a great theologian nor a profound thinker, but he was the most learned man of his age, and stood high in favour with the emperor Constantine. At the council of Nicaea in 325 he took a prominent part, occupying a seat at the emperor’s right hand, and being appointed to deliver the panegyrical oration in his honour. He was the leader of the large middle party of Moderates at the council, and submitted the first draft of the creed which was afterwards adopted with important changes and additions. In the beginning he was the most influential man present, but was finally forced to yield to the Alexandrian party, and to vote for a creed which completely repudiated the position of the Arians, with whom he had himself been hitherto more in sympathy than with the Alexandrians. He was placed in a difficult predicament by the action of the council, and his letter to the Caesarean church explaining his conduct is exceedingly interesting and instructive (see Socrates, Hist. Eccl. i. 8, and cf. McGiffert’s translation of Eusebius’ Church History, p. 15 sq.). To understand his conduct, it is necessary to look briefly at his theological position. By many he has been called an Arian, by many his orthodoxy has been defended. The truth is, three stages are to be distinguished in his theological development. The first preceded the outbreak of the Arian controversy, when, as might be expected in a follower of Origen, his interest was anti-Sabellian and his emphasis chiefly upon the subordination of the Son of God. In his works written during this period (for instance, the Praeparatio evangelica and Demonstratio evangelica), as in the works of Origen himself and other ante-Nicene fathers, expressions occur looking in the direction of Arianism, and others looking in the opposite direction. The second stage began with the outbreak of the controversy in 318, and continued until the Nicene Council. During this period he took the side of Arius in the dispute with Alexander of Alexandria, and accepted what he understood to be the position of Arius and his supporters, who, as he supposed, taught both the divinity and subordination of the Son. It was natural that he should take this side, for in his traditional fear of Sabellianism, in which he was one with the followers of Origen in general, he found it difficult to approve the position of Alexander, who seemed to be doing away altogether with the subordination of the Son. And, moreover, he believed that Alexander was misrepresenting the teaching of Arius and doing him great injustice (cf. his letters to Alexander and Euphration preserved in the proceedings of the second council of Nicaea, Act. vi. tom. 5: see Mansi’s Concilia, xiii. 316 sq.; English translation in McGiffert, op. cit. p. 70). Meanwhile at the council of Nicaea he seems to have discovered that the Alexandrians were right in claiming that Arius was carrying his subordinationism so far as to deny all real divinity to Christ. To this length Eusebius himself was unwilling to go, and so, convinced that he had misunderstood Arius, and that the teaching of the latter was imperilling the historic belief in the divinity of Christ, he gave his support to the opposition, and voted for the Nicene Creed, in which the teachings of the Arians were repudiated. From this time on he was a supporter of Nicene orthodoxy over against Arianism (cf., e.g., his Contra Marcellum, De ecclesiastica theologia, and Theophania). But he never felt in sympathy with the extreme views of the Athanasian party, for they seemed to him to savour of Sabellianism, which always remained his chief dread (cf. his two works against Marcellus of Ancyra). His personal friends, moreover, were principally among the Arians, and he was more closely identified with them than with the supporters of Athanasius. But he was always a man of peace, and while commonly counted one of the opponents of Athanasius, he did not take a place of leadership among them as his position and standing would have justified him in doing, and Athanasius never spoke of him with bitterness as he did of other prominent men in the party.
