In recent years, a growing number of New Testament scholars have questioned traditional portrayals of the Apostle Paul as a leader of a new religious movement that set faith in Christ in opposition to the Jewish tradition. Instead, they have stressed the need to interpret Paul from within the Judaism of his day, regarding him as a faithful Jew who cherished deeply his Jewish identity and saw observance of the Mosaic law or Torah among Jewish believers in Christ as a good thing. While the present work argues strongly in favor of this latter interpretation of Paul, it also seeks to delve deeper into his thought in order to explore at length the points of continuity and convergence between Paul and the Judaism(s) of his day as well as the beliefs that distinguished him from his fellow Jews who did not share his faith in Christ.Chief among these beliefs was the conviction that the identity and will of God were now to be defined primarily on the basis of his relation to Jesus his Son, through whom he had intended from the start to accomplish his purposes for Israel and the world.

While Paul expected his fellow Jews to continue to live as Jews and members of Israel within this community, which he called the ekklēsia, his conviction that those non-Jews who lived faithfully as part of the same community yet did not submit fully to the Mosaic law were equally acceptable and righteous in God's sight led him to oppose all attempts to impose on them the observance of that law. Such attempts implied that the members of the community who observed the law were to be regarded as more righteous or as superior in some way to those who did not and thus threatened to destroy the very fabric of the communities that Paul had worked so hard to establish.Rather than running contr
