Author(s): Bishop of Caesarea Eusebius
Eusebius' account is the only surviving historical record of the Church during its crucial first 300 years. Bishop Eusebius, a learned scholar who lived most of his life in Caesarea in Palestine, broke new ground in writing the History and provided a model for all later ecclesiastical historians. In tracing the history of the Church from the time of Christ to the Great Persecution at the beginning of the fourth century, and ending with the conversion of the Emperor Constantine, his aim was to show the purity and continuity of the doctrinal tradition of Christianity and its struggle against persecutors and heretics.
The so-called 'Father of Ecclesiastical History', Eusebius (263-339) was a Greek Christian. His prodigious literary output can be grouped into four categories: the historical, the apologetic, the Biblical and the dogmatic. G.A Williamson was a renowned scholar of the Classics.
