The Church History (Greek: Ἐκκλησιαστικὴ ἱστορία; Latin: Historia Ecclesiastica or Historia Ecclesiae) of Eusebius, the bishop of Caesarea was a 4th-century pioneer work giving a chronological account of the development of Early Christianity from the 1st century to the 4th century. It was written in Koine Greek, and survives also in Latin, Syriac and Armenian manuscripts.
The result was the first full-length historical narrative written from a Christian point of view. In the early 5th century, two advocates in Constantinople, Socrates Scholasticus and Sozomen, and a bishop, Theodoret of Cyrrhus, Syria, wrote continuations of Eusebius' church history, establishing the convention of continuators that would determine to a great extent the way history was written for the next thousand years. Eusebius' Chronicle, which attempted to lay out a comparative timeline of pagan and Old Testament history, set the model for the other historiographical genre, the medieval chronicle or universal history.
Eusebius had access to the Theological Library of Caesarea and made use of many ecclesiastical monuments and documents, acts of the martyrs, letters, extracts from earlier Christian writings, lists of bishops, and similar sources, often quoting the originals at great length so that his work contains materials not elsewhere preserved. For example, he wrote that Matthew composed the Gospel according to the Hebrews and his Church Catalogue suggests that it was the only Jewish gospel.
It is therefore of historical value, though it pretends neither to completeness nor to the observance of due proportion in the treatment of the subject-matter. Nor does it present in a connected and systematic way the history of the early Christian Church. It is to no small extent a vindication of the Christian religion, though the author did not primarily intend it as such. Eusebius has been often accused of intentional falsification of the truth; in judging persons or facts he is not entirely unbiased.
Eusebius attempted according to his own declaration (I.i.1) to present the history of the Church from the apostles to his own time, with special regard to the following points:
He grouped his material according to the reigns of the emperors, presenting it as he found it in his sources. The contents are as follows:
Andrew Louth has argued that the Church History was first published in 313 CE. In its present form, the work was brought to a conclusion before the death of Crispus (July 326), and, since book x is dedicated to Paulinus, Archbishop of Tyre, who died before 325, at the end of 323 or in 324. This work required the most comprehensive preparatory studies, and it must have occupied him for years. His collection of martyrdoms of the older period may have been one of these preparatory studies.
The accuracy of Eusebius' account has often been called into question. In the 5th century, the Christian historian Socrates Scholasticus described Eusebius as writing for “rhetorical finish” in his Vita Constantini and for the “praises of the Emperor” rather than the “accurate statement of facts.” The methods of Eusebius were criticised by Edward Gibbon in the 18th century. In the 19th century Jacob Burckhardt viewed Eusebius as 'a liar', the “first thoroughly dishonest historian of antiquity.” Ramsay MacMullen in the 20th century regarded Eusebius' work as representative of early Christian historical accounts in which “Hostile writings and discarded views were not recopied or passed on, or they were actively suppressed... matters discreditable to the faith were to be consigned to silence.” As a consequence this kind of methodology in MacMullen's view has distorted modern attempts, (e.g. Harnack, Nock, and Brady), to describe how the Church grew in the early centuries. Arnaldo Momigliano wrote that in Eusebius' mind "chronology was something between an exact science and an instrument of propaganda "
The work was translated into other languages in ancient time (Latin, Syriac, Armenian). Codex Syriac 1 housed at the National Library of Russia is one of the oldest Syriac manuscripts, dated to the year 462. The first English translation was by Mary Basset, the granddaughter of Sir Thomas More, made between 1544 and 1553; the first version to be printed was by Meredith Hanmer, in 1576.
