In the early nineteenth century there was a [[Tübingen School]] of conservative theology led by J.C.F. Steudel at the University of Tübingen. But the Tübingen School commonly referred to is that headed by F.C. Baur,* who taught there from 1826 until his death in 1860. Baur’s teaching was characterized by his anti-supernaturalistic attitude to history, tendency criticism in the interpretation of biblical writings, and the use of idealist philosophy in the interpretation of history. He saw a fundamental conflict between the Jewish church led by Peter and the Hellenistic Gentile church led by Paul. The degree in which NT books exhibited tendencies of this conflict determined their authenticity. Baur assigned most of them to the second century.
