Paul's letters depict gentiles and Jews with different characteristics of sin. This article focuses on Paul's rhetoric about Jewish shortcomings and argues that he has an eschatological myth of Jewish sin: it is the period in the Jewish deity's plan when he has hardened his people into disobedience and disloyalty. While scholars have traditionally tried to connect Paul's ideas about Jewish sin to deficiencies of historical Jews, Paul's claims are primarily animated by his Jewish eschatological scheme and competitive rhetorical needs. Paul re-emerges as a Jewish writer within his competitive social landscape wherein ethnic differentiation was an expected way of imagining the human and divine realms.
