" The apostle Paul often appears in Christian thought as the one chiefly responsible for the de-Judaization of the gospel and even for the transmutation of the person of Jesus from a rabbi in the Jewish sense to a divine being in the Greek sense. Such an interpretation of Paul became almost canonical in certain schools of biblical criticism during the nineteenth century, especially that of Ferdinand Christian Baur, who saw the controversy between Paul and Peter as a conflict between the party of Peter, with its 'Judaizing' distortion of the gospel into a new law, and the party of Paul, with its universal vision of the gospel as a message about Jesus for all humanity. Very often, of course, this description of the opposition between Peter and Paul and between law and gospel was cast in the language of the opposition between Roman Catholicism (which traced its succession to Peter as the first pope) and Protestantism (which arose from Luther's interpretation of the epistles of Paul). Luther's favorite among those epistles, the letter to the Romans, became the charter for this supposed declaration of independence from Judaism. "
