ToursExplore Lably’s 3D toursTogether with Pamphilus, Eusebius was a scholar of the biblical canon and is regarded as one of the most learned Christians during late antiquity. He wrote the Demonstrations of the Gospel, Preparations for the Gospel and On Discrepancies between the Gospels, studies of the biblical text. His work Onomasticon is an early geographical lexicon of places in the Holy Land mentioned in the Bible. As "Father of Church history" (not to be confused with the title of Church Father), he produced the Ecclesiastical History, On the Life of Pamphilus, the Chronicle and On the Martyrs. He also produced a biographical work on Constantine the Great, the first Christian Roman emperor, who was Augustus between AD 306 and AD 337.
Early life
Most scholars date the birth of Eusebius to some point between AD 260 and 265. He was most likely born in or around Caesarea Maritima. Nothing is known about his parents. He was baptized and instructed in the city, and lived in Syria Palaestina in 296, when Diocletian's army passed through the region (in the Life of Constantine, Eusebius recalls seeing Constantine traveling with the army).
Eusebius was made presbyter by Agapius of Caesarea. Some, like theologian and ecclesiastical historian John Henry Newman, understand Eusebius's statement that he had heard Dorotheus of Tyre "expound the Scriptures wisely in the Church" to indicate that Eusebius was Dorotheus's pupil while the priest was resident in Antioch; others, like the scholar D. S. Wallace-Hadrill, deem the phrase too ambiguous to support the contention.
Through the activities of the theologian Origen (185/6–254) and the school of his follower Pamphilus (later 3rd century – 309), Caesarea became a center of Christian learning. Origen was largely responsible for the collection of usage information, or which churches were using which gospels, regarding the texts which became the New Testament. The information used to create the late-fourth-century Easter Letter, which declared accepted Christian writings, was probably based on the Ecclesiastical History [HE] of Eusebius of Caesarea, wherein he uses the information passed on to him by Origen to create both his list at HE 3:25 and Origen's list at HE 6:25. Eusebius got his information about what texts were accepted by the third-century churches throughout the known world, a great deal of which Origen knew of firsthand from his extensive travels, from the library and writings of Origen.
On his deathbed, Origen had made a bequest of his private library to the Christian community in the city. Together with the books of his patron Ambrosius, Origen's library (including the original manuscripts of his works) formed the core of the collection that Pamphilus established. Pamphilus also managed a school that was similar to (or perhaps a re-establishment of) that of Origen. He was compared to Demetrius of Phalerum—as well as to another (evidently, learnèd) scholar by the name of "Pisistratus"—for Pamphilus had gathered Bibles "from all parts of the world". Like his model Origen, Pamphilus maintained close contact with his students. Eusebius, in his history of the persecutions, alludes to the fact that many of the Caesarean martyrs lived together, presumably under Pamphilus.
Soon after Pamphilus settled in Caesarea (c. 280s), he began teaching Eusebius, who was then somewhere between twenty and twenty-five. Because of his close relationship with his schoolmaster, Eusebius was sometimes called Eusebius Pamphili: "Eusebius, son of Pamphilus". The name may also indicate that Eusebius was made Pamphilus's heir. Pamphilus gave Eusebius a strong admiration for the thought of Origen. Neither Pamphilus nor Eusebius knew Origen personally; Pamphilus probably picked up Origenist ideas during his studies under Pierius (nicknamed "Origen Junior") in Alexandria.
Eusebius's Preparation for the Gospel bears witness to the literary tastes of Origen: Eusebius quotes no comedy, tragedy, or lyric poetry, but makes reference to all the works of Plato and to an extensive range of later philosophic works, largely from Middle Platonists from Philo to the late 2nd century. Whatever its secular contents, the primary aim of Origen and Pamphilus's school was to promote sacred learning. The library's biblical and theological contents were more impressive: Origen's Hexapla and Tetrapla; a copy of the original Aramaic version of the Gospel of Matthew; and many of Origen's own writings. Marginal comments in extant manuscripts note that Pamphilus and his friends and pupils, including Eusebius, corrected and revised much of the biblical text in their library. Their efforts made the hexaplaric Septuagint text increasingly popular in Syria and Palestine. Soon after joining Pamphilus's school, Eusebius started helping his master expand the library's collections and broaden access to its resources. At about this time Eusebius compiled a Collection of Ancient Martyrdoms, presumably for use as a general reference tool.
In the 290s, Eusebius began work on his most important work, the Ecclesiastical History, a narrative history of the Church and Christian community from the Apostolic Age to Eusebius's own time. At about the same time, he worked on his Chronicle, a universal calendar of events from the Creation to, again, Eusebius's own time. He completed the first editions of the Ecclesiastical History and Chronicle before 300.

Bishop of Caesarea
Eusebius succeeded Agapius as Bishop of Caesarea soon after 313 and was called on by Arius who had been excommunicated by his bishop Alexander of Alexandria. An episcopal council in Caesarea pronounced Arius blameless. Eusebius enjoyed the favor of the Emperor Constantine. Because of this he was called upon to present the creed of his own church to the 318 attendees of the Council of Nicaea in 325. However, the anti-Arian creed from Palestine prevailed, becoming the basis for the Nicene Creed.
The theological views of Arius, that taught the subordination of the Son to the Father, continued to be controversial. Eustathius of Antioch strongly opposed the growing influence of Origen's theology as the root of Arianism. Eusebius, an admirer of Origen, was reproached by Eustathius for deviating from the Nicene faith. Eusebius prevailed and Eustathius was deposed at a synod in Antioch.
However, Athanasius of Alexandria became a more powerful opponent and in 334 he was summoned before a synod in Caesarea (which he refused to attend). In the following year, he was again summoned before a synod in Tyre at which Eusebius of Caesarea presided. Athanasius, foreseeing the result, went to Constantinople to bring his cause before the Emperor. Constantine called the bishops to his court, among them Eusebius. Athanasius was condemned and exiled at the end of 335. Eusebius remained in the Emperor's favour throughout this time and more than once was exonerated with the explicit approval of the Emperor Constantine. After the Emperor's death (c. 337), Eusebius wrote the Life of Constantine, an important historical work because of eyewitness accounts and the use of primary sources.
Doctrine
Eusebius is fairly unusual in his preterist, or fulfilled, eschatological view. Saying "the Holy Scriptures foretell that there will be unmistakable signs of the Coming of Christ. Now there were among the Hebrews three outstanding offices of dignity, which made the nation famous, firstly the kingship, secondly that of prophet, and lastly the high priesthood. The prophecies said that the abolition and complete destruction of all these three together would be the sign of the presence of the Christ. And that the proofs that the times had come, would lie in the ceasing of the Mosaic worship, the desolation of Jerusalem and its Temple, and the subjection of the whole Jewish race to its enemies. ...The holy oracles foretold that all these changes, which had not been made in the days of the prophets of old, would take place at the coming of the Christ, which I will presently shew to have been fulfilled as never before in accordance with the predictions" (Demonstratio Evangelica VIII).
From a dogmatic point of view, Eusebius is related in his views to Origen. Like Origen, he started from the fundamental thought of the absolute sovereignty (monarchia) of God. God is the cause of all beings. But he is not merely a cause; in him everything good is included, from him all life originates, and he is the source of all virtue. God sent Christ into the world that it may partake of the blessings included in the essence of God. Eusebius expressly distinguishes the Son as distinct from Father as a ray is also distinct from its source the sun.
Eusebius held that men were sinners by their own free choice and not by the necessity of their natures. Eusebius said:
The Creator of all things has impressed a natural law upon the soul of every man, as an assistant and ally in his conduct, pointing out to him the right way by this law; but, by the free liberty with which he is endowed, making the choice of what is best worthy of praise and acceptance, he has acted rightly, not by force, but from his own free-will, when he had it in his power to act otherwise, As, again, making him who chooses what is worst, deserving of blame and punishment, because he has by his own motion neglected the natural law, and becoming the origin and fountain of wickedness, and misusing himself, not from any extraneous necessity, but from free will and judgment. The fault is in him who chooses, not in God. For God has not made nature or the substance of the soul bad; for he who is good can make nothing but what is good. Everything is good which is according to nature. Every rational soul has naturally a good free-will, formed for the choice of what is good. But when a man acts wrongly, nature is not to be blamed; for what is wrong, takes place not according to nature, but contrary to nature, it being the work of choice, and not of nature.
A letter Eusebius is supposed to have written to Constantine's daughter Constantina, refusing to fulfill her request for images of Christ, was quoted in the decrees (now lost) of the Iconoclast Council of Hieria in 754, and later quoted in part in the rebuttal of the Hieria decrees in the Second Council of Nicaea of 787, now the only source from which some of the text is known. The authenticity or authorship of the letter remains uncertain.
Nicene Creed
In the June 2002 issue of the Church History journal, Pier Franco Beatrice reports that Eusebius testified that the word homoousios (consubstantial) "was inserted in the Nicene Creed solely by the personal order of Constantine."
According to Eusebius of Caesarea, the word homoousios was inserted in the Nicene Creed solely by the personal order of Constantine. But this statement is highly problematic. It is very difficult to explain the seeming paradoxical fact that this word, along with the explanation given by Constantine, was accepted by the "Arian" Eusebius, whereas it has left no traces at all in the works of his opponents, the leaders of the anti-Arian party such as Alexander of Alexandria, Ossius of Cordova, Marcellus of Ancyra, and Eustathius of Antioch, who are usually considered Constantine's theological advisers and the strongest supporters of the council. Neither before nor during Constantine's time is there any evidence of a normal, well-established Christian use of the term homoousios in its strictly Trinitarian meaning. Having once excluded any relationship of the Nicene homoousios with the Christian tradition, it becomes legitimate to propose a new explanation, based on an analysis of two pagan documents which have so far never been taken into account. The main thesis of this paper is that homoousios came straight from Constantine's Hermetic background. As can be clearly seen in the Poimandres, and even more clearly in an inscription mentioned exclusively in the Theosophia, in the theological language of Egyptian paganism the word homoousios meant that the Nous-Father and the Logos-Son, who are two distinct beings, share the same perfection of the divine nature.
— Pier Franco Beatrice, "The Word 'Homoousios' from Hellenism to Christianity", Church History, Volume 71, № 2, June 2002, p. 243
However, the council evidently did not force the insertion of the word and instead adopted a text related to the confession of Jerusalem. The role of Constantine remained uncertain during the council.
Assessment
- Socrates Scholasticus (a 5th-century Christian historian), writing in his own Church History, criticized the Life of Constantine, stating that Eusebius was "more intent on the rhetorical finish of his composition and the praises of the emperor, than on an accurate statement of facts".
- Edward Gibbon openly distrusted the writings of Eusebius concerning the number of martyrs, by noting a passage in the shorter text of the Martyrs of Palestine attached to the Ecclesiastical History (Book 8, Chapter 2) in which Eusebius introduces his description of the martyrs of the Great Persecution under Diocletian with: "Wherefore we have decided to relate nothing concerning them except the things in which we can vindicate the Divine judgment. ... We shall introduce into this history in general only those events which may be useful first to ourselves and afterwards to posterity." In the longer text of the same work, chapter 12, Eusebius states: "I think it best to pass by all the other events which occurred in the meantime: such as ... the lust of power on the part of many, the disorderly and unlawful ordinations, and the schisms among the confessors themselves; also the novelties which were zealously devised against the remnants of the Church by the new and factious members, who added innovation after innovation and forced them in unsparingly among the calamities of the persecution, heaping misfortune upon misfortune. I judge it more suitable to shun and avoid the account of these things, as I said at the beginning."
- When his own honesty was challenged by his contemporaries, Gibbon appealed to a chapter heading in Eusebius's Praeparatio evangelica (Book XII, Chapter 31) in which Eusebius represents Plato as saying "that it will be necessary sometimes to use falsehood as a remedy for the benefit of those who require such a mode of treatment."
- Although Gibbon refers to Eusebius as the "gravest" of the ecclesiastical historians, he also suggests that Eusebius was more concerned with the passing political concerns of his time than with his duty as a reliable historian.
- Jacob Burckhardt (19th century cultural historian) dismissed Eusebius as "the first thoroughly dishonest historian of antiquity".
- Other critics of Eusebius's work cite the panegyrical tone of the Vita, plus the omission of internal Christian conflicts in the Canones, as reasons to interpret his writing with caution.
Alternate views have suggested that Gibbon's dismissal of Eusebius is inappropriate:
- With reference to Gibbon's comments, Joseph Barber Lightfoot (late 19th century theologian and former Bishop of Durham) pointed out that Eusebius's statements indicate his honesty in stating what he was not going to discuss, and also his limitations as a historian in not including such material. He also discusses the question of accuracy. "The manner in which Eusebius deals with his very numerous quotations elsewhere, where we can test his honesty, is a sufficient vindication against this unjust charge." Lightfoot also notes that Eusebius cannot always be relied on: "A far more serious drawback to his value as a historian is the loose and uncritical spirit in which he sometimes deals with his materials. This shows itself in diverse ways. He is not always to be trusted in his discrimination of genuine and spurious documents."
- Averil Cameron (professor at King's College London and Oxford) and Stuart Hall (historian and theologian), in their translation of the Life of Constantine, point out that writers such as Burckhardt found it necessary to attack Eusebius to undermine the ideological legitimacy of the Habsburg empire, which based itself on the idea of Christian empire derived from Constantine, and that the most controversial letter in the Life has since been found among the papyri of Egypt.
- In Church History (Vol. 59, 1990), Michael J. Hollerich (assistant professor at the Jesuit Santa Clara University, California) replies to Burckhardt's criticism of Eusebius, that "Eusebius has been an inviting target for students of the Constantinian era. At one time or another they have characterized him as a political propagandist, a good courtier, the shrewd and worldly adviser of the Emperor Constantine, the great publicist of the first Christian emperor, the first in a long succession of ecclesiastical politicians, the herald of Byzantinism, a political theologian, a political metaphysician, and a caesaropapist. It is obvious that these are not, in the main, neutral descriptions. Much traditional scholarship, sometimes with barely suppressed disdain, has regarded Eusebius as one who risked his orthodoxy and perhaps his character because of his zeal for the Constantinian establishment." Hollerich concludes that "the standard assessment has exaggerated the importance of political themes and political motives in Eusebius's life and writings and has failed to do justice to him as a churchman and a scholar".
While many have shared Burckhardt's assessment, particularly with reference to the Life of Constantine, others, while not pretending to extol his merits, have acknowledged the irreplaceable value of his works which may principally reside in the copious quotations that they contain from other sources, often lost.
Veneration
The earliest recorded feast day of Eusebius is found in the earliest known Syrian Martyrology dating to the year 411 translated by William Wright. The Martyrology lists his feast day as 30 May. Eusebius continues to be venerated as a Saint by the modern-day Syrian Orthodox Church as well, with a feast day on 29 February according to the official calendar of Saints created by Corbishop Rajan Achen.
Eusebius's status as a saint in the Catholic Church is at least unclear. He is listed in the Sacrae theologiae summa expressly as an 'ecclesiastical writer,' defined in contrast to Church Fathers as those writers in whom might be found "orthodoxy recognized by the Church, but no holiness or antiquity."
Bishop J. B. Lightfoot writes in his entry for Eusebius in Henry Wace's Dictionary of Christian Biography and Literature to the End of the Sixth Century AD, with an Account of Principal Sects and Heresies (1911) that "in the Martyrologium Romanum itself he held his place for centuries" and in "Gallican service-books the historian is commemorated as a saint." However, Lightfoot notes that in "the revision of this Martyrology under Gregory XIII his name was struck out, and Eusebius of Samosata was substituted, under the mistaken idea that Caesarea had been substituted for Samosata by a mistake." The Roman Catholic author Henri Valois includes in his translations on Eusebius's writings testimonies of ancient authors in favor and against Eusebius; in the former category he includes evidence of Eusebius in several martyrologies and being entitled "Blessed" dating back to Victorius of Aquitaine. Valois includes both Usuardus and Notker, who list his feast as 21 June in the Roman Martyrology, and a Gallican breviary is included for 21 June that reads as follows:
Of the holy Eusebius, bishop and confessor.
Lesson 1. Eusebius, bishop of Cæsarea in Palestine, on account of his friendship with Pamphilus the martyr, took from him the surname of Pamphili; inasmuch as along with this same Pamphilus he was a most diligent investigator of sacred literature. The man indeed is very worthy of being remembered in these times, both for his skill in many things, and for his wonderful genius, and by both Gentiles and Christians he was held distinguished and most noble among philosophers. This man, after having for a time labored in behalf of the Arian heresy, coming to the council of Nicæa, inspired by the Holy Spirit, followed the decision of the Fathers, and thereafter up to the time of his death lived in a most holy manner in the orthodox faith.
Lesson 2. He was, moreover, very zealous in the study of the sacred Scriptures, and along with Pamphilus the martyr was a most diligent investigator of sacred literature. At the same time he has written many things, but especially the following books: The Præparatio Evangelica, the Ecclesiastical History, Against Porphyry, a very bitter enemy of the Christians; he has also composed Six Apologies in Behalf of Origen, a Life of Pamphilus the Martyr, from whom on account of friendship he took his surname, in three books; likewise very learned Commentaries on the hundred and fifty Psalms.
Lesson 3. Moreover, as we read, after having ascertained the sufferings of many holy martyrs in all the provinces, and the lives of confessors and virgins, he has written concerning these saints twenty books; while on account of these books therefore, and especially on account of his Præparatio Evangelica, he was held most distinguished among the Gentiles, because of his love of truth he contemned the ancestral worship of the gods. He has written also a Chronicle, extending from the first year of Abraham up to the year 300 AD, which the divine Hieronymus has continued. Finally this Eusebius, after the conversion of Constantine the Great, was united to him by strong friendship as long as he lived.
A bone fragment relic of Eusebius within its original reliquary is on display at the Shrine of All Saints located within St. Martha's Catholic Church in Morton Grove, Illinois.
