Geiger equated Jewish Orthodoxy with Catholic-style hegemonic claims

Evidence

In an 1841 letter to the historian Leopolz Zunz, Geiger even compared Orthodoxy to Catholicism in the way it sought hegemony! … By contrast, Geiger asserted that the Judaism from which Islam emerged had been the purest form of the Jewish religion and that which most closely corresponded to Reform Judaism: it was monotheistic, bound to biblical prophecy, and based on divine revelation. — Ivan Davidson Kalmar, Derek Penslar, Orientalism and the Jews, 387
