The notion of the variety of Jewish theologies echoes the variety found within Israel's sacred scriptures. Paul, in his Torah-centred period, based his theology mainly on notions derived from the Deuteronomistic school; later, after his call to be the apostle of Jesus Christ, he was indebted to the theology of the Priestly Code (see especially the figure of Abraham in Rom 4). Just as the Torah remains the privilege of Israel, so also the covenant. Non-Jews participate in the divine promises. Accordingly, ‘scripture’ as such cannot be invoked as witnessing to Paul's gospel; instead, Pauline theology is constituted on the basis of certain passages found within the corpus of Israel's sacred scriptures.
