Eusebius of Caesarea, ca. 260–340 CE, born in Palestine, was a student of the presbyter Pamphilus whom he loyally supported during Diocletian's persecution. He was himself imprisoned in Egypt, but became Bishop of Caesarea about 314. At the Council of Nicaea in 325 he sat by the emperor, led a party of moderates, and made the first draft of the famous creed.
Of Eusebius's many learned publications we have Martyrs of Palestine and Life of Constantine; several apologetic and polemic works; parts of his commentaries on the Psalms and Isaiah; and the Chronographia, known chiefly in Armenian and Syriac versions of the original Greek. But Eusebius's chief fame rests on the History of the Christian Church in ten books published in 324–325, the most important ecclesiastical history of ancient times, a great treasury of knowledge about the early Church.
Eusebius of Caesarea (c. AD 263 – 339) also called Eusebius Pamphili, was a Roman historian, exegete and Christian polemicist. He became the Bishop of Caesarea in Palestine about the year 314. Together with Pamphilus, he was a scholar of the Biblical canon. He wrote Demonstrations of the Gospel, Preparations for the Gospel, and On Discrepancies between the Gospels, studies of the Biblical text. As "Father of Church History" he produced the Ecclesiastical History, On the Life of Pamphilus, the Chronicle and On the Martyrs.
I think the most interesting portion of Books VI-X is Eusebius' treatment of Nepos, an early millenarian (excerpt below). Beyond the obvious interestingness of someone in the middle of the third century not only viewing Revelation as authoritative but also reading it literally, it also interests me that the Alexandrian church, which was so ready to brand people as heretics, did not brand Nepos so, its bishop Dionysius acknowledging him as a beloved brother who was able in the Scriptures yet erring in one point.
Chapter 24. Nepos and his Schism.
1. Besides all these the two books on the Promises were prepared by him. The occasion of these was Nepos, a bishop in Egypt, who taught that the promises to the holy men in the Divine Scriptures should be understood in a more Jewish manner, and that there would be a certain millennium of bodily luxury upon this earth.
2. As he thought that he could establish his private opinion by the Revelation of John, he wrote a book on this subject, entitled Refutation of Allegorists.
3. Dionysius opposes this in his books on the Promises. In the first he gives his own opinion of the dogma; and in the second he treats of the Revelation of John, and mentioning Nepos at the beginning, writes of him in this manner:
4. But since they bring forward a certain work of Nepos, on which they rely confidently, as if it proved beyond dispute that there will be a reign of Christ upon earth, I confess that in many other respects I approve and love Nepos, for his faith and industry and diligence in the Scriptures, and for his extensive psalmody, with which many of the brethren are still delighted; and I hold him in the more reverence because he has gone to rest before us. But the truth should be loved and honored most of all. And while we should praise and approve ungrudgingly what is said aright, we ought to examine and correct what does not seem to have been written soundly.
