The label “Old Testament” would not have made sense to anyone in the first century as a description of Jewish sacred writings. The bottom line is that Scripture for Paul always refers to a collection of unambiguously Jewish sacred texts, that he uses the terminology of law (nomos, which may also be translated “Torah”) as a synonym for the Scriptures, and these sacred writings are no less authoritative for the apostle after his encounter with Jesus than they were before it.
