A contemporary of the emperor Constantine, Bishop Eusebius of Caesarea invested a considerable portion of his scholarly energy in a sweeping history of the Church from the era of the apostles until his own. In this volume of the Fathers of the Church series, Books Six through Ten of his Historia ecclesiastica describe the actors and events from the persecution of Septimius Severus (Roman emperor, 193-211) until the Constantinian era of toleration and the restoration of the churches. An oft-consulted source on the life of Origen (mid-third century), Eusebius's writing reveals his own perspective on divine providence acting in history.
