The Church History (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. 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, that 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.
