Ferdinand Christian Baur (21 June 1792 – 2 December 1860) was a German Protestant theologian and founder and leader of the (new) Tübingen School of theology (named for the University of Tübingen where Baur studied and taught). Following Hegel's theory of dialectic, Baur argued that second century Christianity represented the synthesis of two opposing theses: Jewish Christianity (Petrine Christianity) and Gentile Christianity (Pauline Christianity). This and the rest of Baur's work had a profound impact upon higher criticism of biblical and related texts.
