The history of the development of Christianity dates of course form the departure of Jesus from the world. But in Paul, this history has a new beginning; from this point we are able to trace it not only in its external features, but also in its inner connection. F.C. Baur traces the rise and development of Christianity through the first three centuries.
Ferdinand Christian Baur (1792–1860) was educated at the University of Tübingen where he later taught as a professor of theology and is credited with founding the movement known as the “Tübingen School” of New Testament criticism. He applied Hegelian philosophy to Christian history in order to develop a new understanding about how Christianity developed.
