At the Council of Nicæa, which met pursuant to an imperial summons in the year 315 Ensebius played a very prominent part. A description of the opening scenes of the Council is given in his Vita Constantini, III. 10 sq. After the Emperor had entered in pomp and had taken his seat, a bishop who sat next to him upon his right arose and delivered in his honor the opening oration, to which the Emperor replied in a brief Latin address. There can be no doubt that this bishop was our Eusebius. Sozomen (H. E. I. 19) states it directly; and Eusebius, although he does not name the speaker, yet refers to him, as he had referred to the orator at the dedication of Paulinus' church at Tyre, in such a way as to make it clear that it was himself; and moreover in his Fita Constantini, I. 1, he mentions the fact that he had in the midst of an assembly of the servants of God addressed an oration to the Emperor on the occasion of the latter's vicennalia, i.e. in 325 A.D. On the other hand, however, Theodoret (H. E. I. 7) states that this opening oration was delivered by Eustathius, bishop of Antioch; while Theodore of Mopsuestia and Philostorgius (according to Nicetas Choniates, Thes. de arthod. rid. V. 7) assign it to Alexander of Alexandria. As Lightfoot suggests, it is possible to explain the discrepancy in the reports by supposing that Eustathius and Alexander, the two great patriarchs, first addressed a few words to the Emperor and that then Eusebius delivered the regular oration. This supposition is not at all unlikely, for it would be quite proper for the two highest ecclesiastics present to welcome the Emperor formally in behalf of the assembled prelates, before the regular oration was delivered by Eusebius. At the same time, the supposition that one or the other of the two great patriarchs must have delivered the opening address was such a natural one that it may have been adopted by Theodoret and the other writers referred to without any historical basis. It is in any case certain that the regular oration was delivered by Eusebius himself (see the convincing arguments adduced by Stroth, p. xxvii. sq.). This oration is no longer extant, but an idea of its character may be formed from the address delivered by Eusebius at the Emperor's tricennalia (which is still extant under the title De laudibus Canstantini; see below, p. 43) and from the general tone of his Life of Constantine. It was avowedly a panegyric, and undoubtedly as fulsome as it was possible to make it, and his powers in that direction were by no means slight.

That Eusebius, instead of the bishop of some more prominent church, should have been selected to deliver the opening address, may have been in part owing to his recognized standing as the most learned man and the most famous writer in the Church, in part to the fact that he was not as pronounced a partisan as some of his distinguished brethren; for instance, Alexander of Alexandria, and Eusebius of Nicomedia; and finally in some measure to his intimate relations with the Emperor. How and when his intimacy with the latter grew up we do not know. As already remarked, he seems to have become personally acquainted with him many years before, when Constantine passed through Cæsarea in the train of Diocletian, and it may be that a mutual friendship, which was so marked in later years, began at that time. However that may be, Eusebius seems to have possessed special advantages of one kind or another, enabling him to come into personal contact with official circles, and once introduced to imperial notice, his wide learning, sound common sense, genial temper and broad charity would insure him the friendship of the Emperor himself, or of any other worthy officer of state. We have no record of an intimacy between Constantine and Eusebius before the Council of Nicæa, but many clear intimations of it after that time. In fact, it is evident that during the last decade at least of the Emperor's life, few, if any, bishops stood higher in his esteem or enjoyed a larger measure of his confidence. Compare for instance the records of their conversations (contained in the Vita Canstantini, I. 28 and II. 9), of their correspondence (ib. II. 46, III. 61, IV. 35 and 36), and the words of Constantine himself (ib. III. 60). The marked attention paid by him to the speeches delivered by Eusebius in his presence (ib. IV. 33 and 46) is also to be noticed. Eusebius' intimacy with the imperial family is shown likewise in the tone of the letter which he wrote to Constantia, the sister of Constantine and wife of Licinius, in regard to a likeness of Christ which she had asked him to send her. The frankness and freedom with which he remonstrates with her for what he considers mistaken zeal on her part, reveal a degree of familiarity which could have come only from long and cordial relations between himself and his royal correspondent. Whatever other reasons therefore may have combined to indicate Eusebius as the most fitting person to deliver the oration in honor of the Emperor at the Council of Nicæa, there can be little doubt that Constantine's personal friendship for him had much to do with his selection. The action of the Council on the subject of Arianism, and Eusebius' conduct in the matter, have already been discussed. Of the bishops assembled at the Council, not far from three hundred in number (the reports of eye-witnesses vary from two hundred and fifty to three hundred and eighteen), all but two signed the Nicene creed as adopted by the Council. These two, both of them Egyptians, were banished with Arius to Illyria, while Eusebius of Nicomedia, and Theognis of Nicæa, who subscribed the creed itself but refused to assent to its anathemas, were also banished for a time, but soon yielded, and were restored to their churches.

Into the other purposes for which the Nicene Council was called,--the settlement of the dispute respecting the time of observing Easter and the healing of the Meletian schism,--it is not necessary to enter here. We have no record of the part which Eusebius took in these transactions. Lightfoot has abundantly shown (p. 313 sq.) that the common supposition that Eusebius was the author of the paschal cycle of nineteen years is false, and that there is no reason to suppose that he had anything particular to do with the decision of the paschal question at this Council.

PART 7 § 7. Continuance of the Arian Controversy. Eusebius' Relations to the Two Parties.

The Council of Nicæa did not bring the Arian controversy to an end. The orthodox party was victorious, it is true, but the Arians were still determined, and could not give up their enmity against the opponents of Arius, and their hope that they might in the end turn the tables on their antagonists. Meanwhile, within a few years after the Council, a quarrel broke out between our Eusebius and Eustathius, bishop of Antioch, a resolute supporter of Nicene orthodoxy. According to Socrates (H. E. I. 23) and Sozomen (H. E. II. 18) Eustathius accused Eusebius of perverting the Nicene doctrines, while Eusebius denied the charge, and in turn taxed Eustathius with Sabellianism. The quarrel finally became so serious that it was deemed necessary to summon a Council for the investigation of Eustathius' orthodoxy and the settlement of the dispute. This Council met in Antioch in 330 A.D. (see Tillemont, VII. p. 651 sq., for a discussion of the date), and was made up chiefly of bishops of Arian or semi-Arian tendencies. This fact, however, brings no discredit upon Eusebius. The Council was held in another province, and he can have had nothing to do with its composition. In fact, convened, as it was, in Eustathius' own city, it must have been legally organized; and indeed Eustathius himself acknowledged its jurisdiction by appearing before it to answer the charges made against him. Theodoret's absurd account of the origin of the synod and of the accusations brought against Eustathius (H. E. I. 21) bears upon its face the stamp of falsehood, and is, as Hefele has shown (Canciliengeschichte, I. 451), hopelessly in error in its chronology. It is therefore to be rejected as quite worthless. The decision of the Council doubtless fairly represented the views of the majority of the bishops of that section, for we know that Arianism had a very strong hold there. To think of a packed Council and of illegal methods of procedure in procuring the verdict against Eustathius is both unnecessary and unwarrantable. The result of the Council was the deposition of Eustathius from his bishopric and his banishment by the Emperor to Illyria, where he afterward died. There is a division of opinion among our sources in regard to the immediate successor of Eustathius. All of them agree that Eusebius was asked to become bishop of Antioch, but that he refused the honor, and that Euphronius was chosen in his stead. Socrates and Sozomen, however, inform us that the election of Eusebius took place immediately after the deposition of Eustathius, while Theodoret (H. E. I. 22) names Eulalius as Eustathius' immediate successor, and states that he lived but a short time, and that Eusebius was then asked to succeed him. Theodoret is Supported by Jerome (Chron., year of Abr. 2345) and by Philostorgius (H. E. III. 15), both of whom insert a bishop Eulalius between Eustathius and Euphronius. It is easier to suppose that Socrates and Sozomen may have omitted so unimportant a name at this point than that the other three witnesses inserted it without warrant. Socrates indeed implies in the same chapter that his knowledge of these affairs is limited, and it is not surprising that Eusebius' election, which caused a great stir, should have been connected in the mind of later writers immediately with Eustathius' deposition, and the intermediate steps forgotten. It seems probable, therefore, that immediately after the condemnation of Eustathius, Eulalius was appointed in his place, perhaps by the same Council, and that after his death, a few months later, Eusebius, who had meanwhile gone back to Cæsarea, was elected in due order by another Council of neighboring bishops summoned for the purpose, and that he was supported by a large party of citizens. It is noticeable that the letter written by the Emperor to the Council, which wished to transfer Eusebius to Antioch (see Vita Const. III. 62), mentions in its salutation the names of five bishops, but among them is only one (Theodotus who is elsewhere named as present at the Council which deposed Eustathius, while Eusebius of Nicomedia, and Theognis of Nicæa, as well as others whom we know to have been on hand on that occasion, are not referred to by the Emperor. This fact certainly seems to point to a different council.

It is greatly to Eusebius' credit that he refused the call extended to him. Had he been governed simply by selfish ambition he would certainly have accepted it, for the patriarchate of Antioch stood at that time next to Alexandria in point of honor in the Eastern Church. The Emperor commended him very highly for his decision, in his epistles to the people of Antioch and to the Council (Vita Const. III. 60, 62 ), and in that to Eusebius himself (ib. III. 61). He saw in it a desire on Eusebius' part to observe the ancient canon of the Church, which forbade the transfer of a bishop from one see to another. But that in itself can hardly have been sufficient to deter the latter from accepting the high honor offered him, for it was broken without scruple on all sides. It is more probable that he saw that the schism of the Antiochenes would be embittered by the induction into the bishopric of that church of Eustathius' chief opponent, and that he did not feel that he had a right so to divide the Church of God. Eusebius' general character, as known to us, justifies us in supposing that this high motive had much to do with his decision. We may suppose also that so difficult a place can have had no very great attractions for a man of his age and of his peace-loving disposition and scholarly tastes. In Cæsarea he had spent his life; there he had the great library of Pamphilus at his disposal, and leisure to pursue his literary work. In Antioch he would have found himself compelled to plunge into the midst of quarrels and seditions of all kinds, and would have been obliged to devote his entire attention to the performance of his official duties. His own tastes therefore must have conspired with his sense of duty to lead him to reject the proffered call and to remain in the somewhat humbler station which he already occupied.

Not long after the deposition of Eustathius, the Arians and their sympathizers began to work more energetically to accomplish the ruin of Athanasius, their greatest foe. He had become Alexander's successor as bishop of Alexandria in the year 326, and was the acknowledged head of the orthodox party. If he could be brought into discredit, there might be hopes of restoring Arius to his position in Alexandria, and of securing for Arianism a recognition, and finally a dominating influence in the church at large. To the overthrow of Athanasius therefore all good Arians bent their energies. They found ready accomplices in the schismatical Meletians of Egypt, who were bitter enemies of the orthodox church of Alexandria. It was useless to accuse Athanasius of heterodoxy; he was too widely known as the pillar of the orthodox faith. Charges must be framed of another sort, and of a sort to stir up the anger of the Emperor against him. The Arians therefore and the Meletians began to spread the most vile and at the same time absurd stories about Athanasius (see especially the latter's Apol. c. Arian. § 59 sq.). These at last became so notorious that the Emperor summoned Athanasius to appear and make his defense before a council of bishops to be held in Cæsarea (Sozomen, H. E. II. 25; Theodoret, H. E. I. 28). Athanasius, however, fearing that the Council would be composed wholly of his enemies, and that it would therefore be impossible to secure fair play, excused himself and remained away. But in the following year (see Sozomen, H. E. II, 25) he received from the Emperor a summons to appear before a council at Tyre. The summons was too peremptory to admit of a refusal, and Athanasius therefore attended, accompanied by many of his devoted adherents (see Sozomen, ib.; Theodoret, H. E. I. 30; Socrates, H. E. I. 28; Athanasius, Apol. c. Arian. § 71 sq.; Eusebius, Vita Const. IV. 41 sq., and Epiphanius, Hær. LXVIII. 8). After a time, perceiving that he had no chance of receiving fair play, he suddenly withdrew from the Council and proceeded directly to Constantinople, in order to lay his case before the Emperor himself, and to induce the latter to allow him to meet his accusers in his presence, and plead his cause before him. There was nothing for the Synod to do after his flight but to sustain the charges brought against him, some of which he had not stayed to refute, and to pass condemnation upon him. Besides various immoral and sacrilegious deeds of which he was accused, his refusal to appear before the Council of Cæsarea the previous year was made an important item of the prosecution. It was during this Council that Potamo flung at Eusebius the taunt of cowardice, to which reference was made above, and which doubtless did much to confirm Eusebius' distrust of and hostility to the Athanasian party-Whether Eusebius of Cæsarea, as is commonly supposed, or Eusebius of Nicomedia, or some other bishop, presided at this Council we are not able to determine. The account of Epiphanius seems to imply that the former was presiding at the time that Potamo made his untimely accusation. Our sources are, most of them, silent on the matter, but according to Valesius, Eusebius of Nicomedia is named by some of them, but which they are I have not been able to discover. We learn from Socrates (H. E. I. 28), as well as from other sources, that this Synod of Tyre was held in the thirtieth year of Constantine's reign, that is, between July, 334, and July, 335. As the Council was closed only in time for the bishops to reach Jerusalem by July, 335, it is probable that it was convened in 335 rather than in 334. From Sozomen (H. E. II. 25) we learn also that the Synod of Cæsarea had been held the preceding year, therefore in 333 or 334 (the latter being the date commonly given by historians). While the Council of Tyre was still in session, the bishops were commanded by Constantine to proceed immediately to Jerusalem to take part in the approaching festival to be held there on the occasion of his tricennalia. The scene was one of great splendor. Bishops were present from all parts of the world, and the occasion was marked by the dedication of the new and magnificent basilica which Constantine had erected upon the site of Calvary (Theodoret, I. 31; Socrates, I. 28 and 33; Sozomen, II. 26; Eusebius, Vita Canst. IV. 41 and 43). The bishops gathered in Jerusalem at this time held another synod before separating. In this they completed the work begun at Tyre, by re-admitting Arius and his adherents to the communion of the Church (see Socrates, 1. 33, and Sozomen, II. 27). According to Sozomen the Emperor, having been induced to recall Arius from banishment in order to reconsider his case, was presented by the latter with a confession of faith, which was so worded as to convince Constantine of his orthodoxy. He therefore sent Arius and his companion Euzoius to the bishops assembled in Jerusalem with the request that they would examine the confession, and if they were satisfied with its orthodoxy would re-admit them to communion. The Council, which was composed largely of Arius' friends and sympathizers, was only too glad to accede to the Emperor's request.

Meanwhile Athanasius had induced Constantine, out of a sense of justice, to summon the bishops that had condemned him at Tyre to give an account of their proceedings before the Emperor himself at Constantinople. This unexpected, and, doubtless, not altogether welcome summons came while the bishops were at Jerusalem, and the majority of them at once returned home in alarm, while only a few answered the call and repaired to Constantinople. Among these were Eusebius of Nicomedia, Theognis of Nicæa, Patrophilus of Scythopolis, and other prominent Arians, and with them our Eusebius (Athanasius, Apol. c. Arian. §§ 86 and 87; Socrates, I. 33-35; Sozomen, II. 28). The accusers of Athanasius said nothing on this occasion in regard to his alleged immoralities, for which he had been condemned at Tyre, but made another equally trivial accusation against him, and the result was his banishment to Gaul. Whether Constantine banished him because he believed the charge brought against him, or because he wished to preserve him from the machinations of his enemies (as asserted by his son Constantine, and apparently believed by Athanasius himself; see his Apol. c. Arian. § 87), or because he thought that Athanasius' absence would allay the troubles in the Alexandrian church we do not know. The latter supposition seems most probable. In any case he was not recalled from banishment until after Constantine's death. Our Eusebius has been severely condemned by many historians for the part taken by him in the Eustathian controversy and especially in the war against Athanasius. In justice to him a word or two must be spoken in his defense. So far as his relations to Eustathius are concerned, it is to be noticed that the latter commenced the controversy by accusing Eusebius of heterodoxy. Eusebius himself did not begin the quarrel, and very likely had no desire to engage in any such doctrinal strife; but he was compelled to defend himself, and in doing so he could not do otherwise than accuse Eustathius of Sabellianism; for if the latter was not satisfied with Eusebius' orthodoxy, which Eusebius himself believed to be truly Nicene, then he must be leaning too far toward the other extreme; that is, toward Sabellianism. There is no reason to doubt that Eusebius was perfectly straightforward and honorable throughout the whole controversy, and at the Council of Antioch itself. That he was not actuated by unworthy motives, or by a desire for revenge, is evinced by his rejection of the proffered call to Antioch, the acceptance of which would have given him so good an opportunity to triumph over his fallen enemy. It must be admitted, in fact, that Eusebius comes out of this controversy without a stain of any kind upon his character. He honestly believed Eustathius to be a Sabellian, and he acted accordingly.

Eusebius has been blamed still more severely for his treatment of Athanasius. But again the facts must be looked at impartially. It is necessary always to remember that Sabellianism was in the beginning and remained throughout his life the heresy which he most dreaded, and which he had perhaps most reason to dread. He must, even at the Council of Nicæa, have suspected Athanasius, who laid so much stress upon the unity of essence on the part of Father and Son, of a leaning toward Sabellianistic principles; and this suspicion must have been increased when he discovered, as he believed, that Athanasitis' most staunch supporter, Eustathius, was a genuine Sabellian. Moreover, on the other side, it is to be remembered that Eusebius of Nicomedia, and all the other leading Arians, had signed the Nicene creed and had proclaimed themselves thoroughly in sympathy with its teaching. Our Eusebius, knowing the change that had taken place in his own mind upon the controverted points, may well have believed that their views had undergone even a greater change, and that they were perfectly honest in their protestations of orthodoxy. And finally, when Arius himself presented a confession of faith which led the Emperor, who had had a personal interview with him, to believe that he had altered his views and was in complete harmony with the Nicene faith, it is not surprising that our Eusebius, who was naturally unsuspicious, conciliatory and peace-loving, should think the same thing, and be glad to receive Arius back into communion, while at the same time remaining perfectly loyal to the orthodoxy of the Nicene creed which he had subscribed. Meanwhile his suspicions of the Arian party being in large measure allayed, and his distrust of the orthodoxy of Athanasius and of his adherents being increased by the course of events, it was only natural that he should lend more or less credence to the calumnies which were so industriously circulated against Athanasius. To charge him with dishonesty for being influenced by these reports, which seem to us so absurd and palpably calumnious, is quite unwarranted. Constantine, who was, if not a theologian, at least a clear-headed and sharp-sighted man, believed them, and why should Eusebius not have done the same? The incident which took place at the Council of Tyre in connection with Potamo and himself was important; for whatever doubts he may have had up to that time as to the truth of the accusations made against Athanasius and his adherents, Potamo's conduct convinced him that the charges of tyranny and high-handed dealing brought against the whole party were quite true. It could not be otherwise than that he should believe that the good of the Alexandrian church, and therefore of the Church at large, demanded the deposition of the seditious and tyrannous archbishop, who was at the same time quite probably Sabellianistic in his tendencies. It must in justice be noted that there is not the slightest reason to suppose that our Eusebius had anything to do with the dishonorable intrigues of the Arian party throughout this controversy. Athanasius, who cannot say enough in condemnation of the tactics of Eusebius of Nicomedia and his supporters, never mentions Eusebius of Cæsarea in a tone of bitterness. He refers to him occasionally as a member of the opposite party, but he has no complaints to utter against him, as he has against the others. This is very significant, and should put an end to all suspicions of unworthy conduct on Eusebius' part. It is to be observed that the latter, though having good cause as he believed to condemn Athanasius and his adherents, never acted as a leader in the war against them. His name, if mentioned at all, occurs always toward the end of the list as one of the minor combatants, although his position and his learning would have entitled him to take the most prominent position in the whole affair, if he had cared to. He was but true to his general character in shrinking from such a controversy, and in taking part in it only in so far as his conscience compelled him to. We may suspect indeed that he would not have made one of the small party that repaired to Constantinople in response to the Emperor's imperious summons had it not been for the celebration of Constantine's tricennalia, which was taking place there at the time, and at which he delivered, on the special invitation of the Emperor and in his presence, one of his greatest orations. Certain it is, from the account which he gives in his Vita Constantini, that both in Constantinople and in Jerusalem the festival of the tricennalia, with its attendant ceremonies, interested him much more than did the condemnation of Athanasius.

PART 8 § 8. Eusebius and Marcellus.

It was during this visit to Constantinople that another synod was held, at which Eusebius was present, and the result of which was the condemnation and deposition of the bishop Marcellus of Ancyra (see Socrates, I. 36; Sozomen, II. 33; Eusebius, Contra Marc. II. 4). The attitude of our Eusebius toward Marcellus is again significant of his theological tendencies. Marcellus had written a book against Asterius, a prominent Arian, in which, in his zeal for the Nicene orthodoxy, he had laid himself open to the charge of Sabellianism. On this account he was deposed by the Constantinopolitan Synod, and our Eusebius was urged to write a work exposing his errors and defending the action of the Council. As a consequence he composed his two works against Marcelins which will be described later. That Eusebius, if not in the case of Athanasius and possibly not in that of Eustathius, had at least in the present case good ground for the belief that Marcellus was a Sabellian, or Sabellianistic in tendency, is abundantly proved by the citations which he makes from Marcellus' own works; and, moreover, his judgment and that of the Synod was later confirmed even by Athanasius himself. Though not suspecting Marcellus for some time, Athanasius finally became convinced that he had deviated from the path of orthodoxy, and, as Newman has shown (in his introduction to Athanasius' fourth discourse against the Arians, Oxford Library of the Fathers, vol. 19, p. 503 sq.), directed that discourse against his errors and those of his followers.

The controversy with Marcellus seems to have been the last in which Eusebius was engaged, and it was opposition to the dreaded heresy of Sabellius which moved him here as in all the other cases. It is important to emphasize, however, what is often overlooked, that though Eusebius during these years was so continuously engaged in controversy with one or another of the members of the anti-Arian party, there is no evidence that he ever deviated from the doctrinal position which he took at the Council of Nicæa. After that date it was never Arianism which he consciously supported; it was never the Nicene orthodoxy which he opposed. He supported those members of the old Arian party who had signed the Nicene creed and protested that they accepted its teaching, against those members of the opposite party whom he believed to be drifting toward Sabellianism, or acting tyrannously and unjustly toward their opponents. The anti-Sabellianistic interest influenced him all the time, but his post-Nicene writings contain no evidence that he had fallen back into the Arianizing position which he had held before 325. They reveal, on the contrary, a fair type of orthodoxy, colored only by its decidedly anti-Sabellian emphasis.

PART 9 § 9. The Death of Eusebius.

In less than two years after the celebration of his tricennalia, on May 22, 337 A.D., the great Constantine breathed his last, in Nicomedia, his former Capital. Eusebius, already an old man, produced a lasting testimonial of his own unbounded affection and admiration for the first Christian emperor, in his Life of Constantine. Soon afterward he followed his imperial friend at the advanced age of nearly, if not quite, eighty years. The exact date of his death is unknown, but it can be fixed approximately. We know from Sozomen (H. E. III. 5) that in the summer of 341, when a council was held at Antioch (on the date of the Council, which we are able to fix with great exactness, see Hefele, Conciliengesch. I. p. 502 sq.) Acacius, Eusebius' successor, was already bishop of Cæsarea. Socrates (H. E. II. 4) and Sozomen (H. E. III. 5) both mention the death of Eusebius and place it shortly before the death of Constantine the younger, which took place early in 340 (see Tillemont's Hist. des Emp. IV. p. 357 sq.), and after the intrigues had begun which resulted in Athanasius' second banishment. We are thus led to place Eusebius' death late in the year 339, or early in the year 340 (cf. Lightfoot's article, p. 318).
