Sanders argued that the traditional Christian interpretation that Paul was condemning Rabbinic legalism was a misunderstanding of both Judaism and Paul's thought, especially since it assumed a level of individualism in these doctrines that was not present, and disregarded notions of group benefit or collective privilege. Rather, Sanders argued, the key difference between pre-Christian Judaism and Pauline teaching was to be found in ideas of how a person becomes one of the People of God. Sanders termed the Jewish belief "covenantal nomism": one was a member of the people by virtue of God's covenant with Abraham, and one stayed in it by keeping the Law.
