Where did it come from?
Translation: Eusebius concocted the "history" of the church!
Quote:By the time Eusebius became bishop of Caesarea around 315, a new vision of the church began to develop. The fantasy of a well-ordered, centralized, and monolithic church had always been around, but Eusebius wanted to make it a reality. In periods of peace, Christians were able to imagine themselves as a church of the present. It was no longer necessary to look to the future for redemption and vindication; they could create the Kingdom of God in the here and now. This possibility and the exciting vision for the church required a new version of the church’s history. Eusebius provided it. Drawing upon the work of Irenaeus and other early church writers, Eusebius set about telling the history of the “apostles” from the time of Christ to his own day.
