Eusebius of Caesarea is best known for his work as a historian: his Chronicle of world history, his Church History and his Life of Constantine. Eusebius was an accomplished biblical scholar. Eusebius virtually created the type of the learned cleric, which has played such an influential role in the history of the Christian Bible. Eusebiusʾ biblical education began when he was a youth living in the household of the wealthy presbyter Pamphilus of Caesarea. Pamphilus had dedicated his wealth to preserving the legacy of Origen of Alexandria. Eusebius devotes greater care and attention to the limits of the incipient New Testament canon. In assessing Eusebiusʾ actual performance as an interpreter of the Bible, it is helpful to distinguish technical aids to exegesis, biblical commentaries in the strict sense of the term, and the use of the Bible in his apologetics.
