"Paul abstracted this universal principle from the concrete phenomenon in the man Jesus, in whom it was interlaced with Jewish presuppositions and strivings, which as such would have been a hindrance to the universal and abiding effectiveness of that principle. ... The religious principle of Jesus was thus certainly freed by Paul from its original Jewish and national husk, but only to be immediately clothed again in a new supernaturalistic envelope, the origin of which likewise lay in the historically given ideas of Hellenism and Pharisaism. Therefore the Pauline Christ can just as little be for us a binding object of faith as the Jesus of history."
