In Christian tradition, Paul is the apostle to the nations. However, his portrayal in the Book of Acts is more nuanced. For a longer period, Paul's ministry is limited to Jews. Only from Acts 13 onwards does Paul slowly emerge as ministering to non-Jews. Yet even then, Paul remains foremost an emissary to diaspora Judaism. In its apology for Paul and his disputed way of including non-Jews into the people of God, Acts emphasises that Paul did so without diminishing the priority of Israel, as a staunch proponent of Jewish monotheism and in a way that took full account of the precarious situation of diaspora Judaism.
