The three subchapters illustrate, how the authors from the Medieval period down to the fifth century have heavily relied on Eusebius of Caesarea’s Church history to writing their own beginnings of Christianity. In addition, they drew heavily on pseudonymous material outside the New Testament canon which they largely ignored. Driven by the challenges of their own times and in answering questions of their own days they developed the beginnings of Christianity from Frankish and late Roman perspectives. In these, vernacular, Greek and Roman cultural elements were deeply inter-related and re-projected into earlier times, while Christianity became regarded as the filter through which to perceive and judge the past.
