Compiled from Naked Bible Podcast episode 420, continuing the “Paul’s Use of the Old Testament” series directly from episode 419 (Romans 1–3). Opening small talk has been trimmed; content is organized topically rather than strictly chronologically.
Halstead frames Romans 4 as serving two purposes at once: first, to show that covenant membership with God never depended on works of Torah such as circumcision, since Abraham himself — the patriarch of the Jewish nation — was declared righteous before he was circumcised; second, to show how God has been faithful to fulfill the Abrahamic covenant specifically through Christ. Both purposes, in Halstead’s framing, continue the project announced across the prior nine episodes: Paul reconfigures inherited Old Testament categories — here, the Abraham story itself — around the Messiah, consistent with (not detached from) what Malachi had already anticipated for Israel’s vocation generally.
Halstead reads Romans 4:1–3 and 4:9–11 closely. Citing Genesis 15:6 (“Abraham believed God, and it was counted to him as righteousness”), Paul’s argument turns on chronology: Abraham is declared righteous in Genesis 15, by faith, and only receives circumcision as “a seal of the righteousness that he had by faith” two chapters later, in Genesis 17. The gap between the two events is, for Halstead, the whole engine of the chapter — Paul exploits the gap (his word, used in a positive sense) to argue that if the founding patriarch of the Jewish nation was justified without circumcision, then Gentiles can be justified the same way, while Abraham simultaneously remains “father” both of uncircumcised believers and of circumcised Jews who walk in Abraham’s own footsteps of faith.
Halstead situates this within the social conflict of the Roman church: “works of law,” in his reading, is a technical term — not works or good deeds generally, but specifically the cultic boundary markers that distinguished Jews as a people (circumcision, Sabbath-keeping, dietary law). Jewish believers in Rome, having come to faith in Jesus, were nonetheless pressing Gentile believers to adopt these same boundary markers as proof of covenant membership. Paul’s counter-argument, via Abraham, is that faith in Christ — not adherence to Jewish cultic markers — is what actually marks out a covenant member.
Halstead pauses to ask a question he frames as genuinely destabilizing: does the historical fact alone — that Abraham was justified before circumcision — logically prove that circumcision is no longer required? He proposes a thought experiment: if Paul traveled back in time and made this same argument to the priests serving at the tabernacle or temple under Moses, Joshua, David, or Solomon, those priests would simply respond that the Torah still commanded circumcision regardless of what happened to Abraham personally. The historical sequence in Genesis, taken by itself, would not have persuaded them, and — Halstead concedes directly — would not actually settle the question on its own terms even for Paul’s own argument.
His resolution is that Paul’s argument does not rest on the bare historical sequence alone. Paul is reading Genesis through two additional lenses simultaneously: his Christology (his settled convictions about who Jesus is) and the Genesis 11–12 narrative arc — humanity’s failure at Babel followed immediately by God’s call of Abraham’s family as the means of rescuing and blessing the nations. On this reading, the Abrahamic covenant was never merely a historical episode; it is, in Halstead’s phrase, “an ongoing story” beginning before the Mosaic law was ever given, a story Paul believes reaches its completion in Christ. Reading Genesis “christologically,” for Halstead, means reading it through that lens — not detaching the text from its own context, but extending a trajectory the text itself already pointed toward.
Working through Romans 4:13–17 verse by verse, Halstead argues: the promise to Abraham and his offspring did not come through Torah but through “the righteousness of faith” (v.13) — a straightforward restatement of the Genesis chronology. If adherents of the law alone are the heirs, “faith is null and the promise is void” (v.14) — meaning, for Halstead, that the Mosaic covenant cannot be read as nullifying or supplanting the earlier Abrahamic promise; whatever Torah’s purpose, that purpose cannot cancel a promise made centuries before Torah existed. Verse 15 (“the law brings wrath”) is read as describing Torah’s actual historical function: it made Israel distinct from the nations (through dietary law restricting shared meals, an ancient marker of social solidarity) but also exposed Israel’s own sinfulness, ultimately driving Israel into exile among the very nations she was supposed to rescue. A law that produces exile cannot be the mechanism by which Abraham’s family blesses the nations; therefore the promise “depends on faith… and is guaranteed to all his offspring” (v.16), both Jewish adherents of the law and Gentiles who share Abraham’s own faith, with Genesis 17:5 (“father of many nations”) cited as confirmation.
Halstead names this reading method explicitly as a “storied approach”: the Abrahamic covenant is read as an ongoing narrative finding completion in Christ, not a closed historical episode reinterpreted after the fact. He is careful to distinguish this from imposing later assumptions onto the text — he draws an analogy to reading Genesis 1–2 without smuggling in modern scientific assumptions, arguing interpretation should be “dialogical” (the interpreter brings assumptions to the text but lets the text correct or confirm them) rather than “unilateral” (imposing assumptions the text cannot speak back to). Heiser presses him on whether this amounts to forcing messianism onto material that doesn’t name Christ; Halstead and Heiser agree that pre-Christian readers could already have expected the Abrahamic covenant to culminate in a messianic figure without yet knowing who that figure was — Paul, writing after the Damascus road christophany, is “not out of step” with that expectation but extends it a further step available only in hindsight. Discontinuity in the details, on this account, turns out to be continuity at the level of the larger story.
Halstead also credits the Damascus road christophany itself as indispensable — not a replacement for Old Testament grounding, but the experiential catalyst that let Paul see what the Old Testament had already been pointing toward. He frames his own approach (citing a colleague, biblical scholar Matthew Thomas, author of a study on Paul and “works of the law”) as that of a “referee”: reporting what the textual data supports rather than either defending Paul reflexively or conceding that Paul invented his theology from nothing.
Halstead’s closing argument turns on vocabulary the ESV obscures. Romans 4:17 describes God as the one “who gives life to the dead” (τοὺς νεκρούς); verse 19 describes Abraham’s own body as “as good as dead” (νενεκρωμένον) and Sarah’s womb as marked by “deadness” (νέκρωσις) — the same νεκρ- root recurring three times across the passage. Halstead argues Paul has deliberately retold the Abraham story using death-and-resurrection vocabulary: Abraham’s body was dead, Sarah’s womb was dead, and God raised life from both — priming the entire Abraham narrative to connect directly to the death and resurrection of Jesus named explicitly in verses 24–25 (“raised for our justification”), and setting up the Adam material Paul will take up next, in Romans 5.
Both hosts close by noting that Romans 4 does not argue for the resurrection as a contested claim; Paul writes to a community that already believes it, and uses it as an interpretive lens — a “prejudgment,” in Halstead’s word — through which the Abraham story is reread, without (in his view) doing interpretive violence to Genesis, since Paul’s christology itself derives from the Old Testament rather than being imported from outside it. The chapter’s payoff, in Halstead’s reading, is ultimately ethical and communal: Abraham stands as father both to circumcised Jewish believers and to uncircumcised Gentile believers on identical terms (faith in the Messiah who fulfills the Abrahamic covenant), addressing the Jew/Gentile tension within the Roman church directly. Halstead notes the same move recurs explicitly in Galatians 3 (“if you are Christ’s, you are Abraham’s seed”). The series will turn to Romans 9–11 next.
