In this episode of The UpWords Podcast, host Jean Geran sits down with biblical scholar Seth Whitaker to explore a question at the heart of Christianity's origins: how do Jews and Christians read Scripture differently—and what holds their interpretive traditions together?
Drawing on his doctoral research at the University of St Andrews on the use of the Psalms in the book of Hebrews, Seth argues that the earliest followers of Jesus were Jews wrestling with their own religious heritage in light of the Messiah. Rather than a clean break, he traces a story of deep continuity — one in which the God of Abraham, Isaac, and Jacob is the same God who raised Jesus from the dead.
Jean and Seth examine why the Old Testament can feel “more vengeful” than the New, and why that contrast is more caricature than reality. Seth offers a striking image: Scripture is not a flat plain where every verse carries equal weight, but a landscape of mountains and valleys, with high peaks of revelation — like God revealing himself as “abounding in steadfast love” at Sinai — that give us a vantage point on the harder passages.
The conversation also draws on a previous UpWords episode with AJ Levine to consider what Christians might learn from Jewish interpretive practices: the “70 faces” of Scripture, a comfort with multiple readings, and the practice of reading sacred texts in community as a guard against going off the rails. Seth closes by tracing how rabbinic Judaism and early Christianity gradually defined themselves over and against one another — shaped by events like the expulsion of Jews from Rome, the destruction of the Temple in 70 CE, and the Bar Kokhba revolt — and why he encourages readers to approach the Hebrew Bible less like a prophecy-fulfillment checklist and more like an ongoing dialogue.
Whether you've wondered how Christianity emerged from Judaism, struggled with the difficult passages of the Old Testament, or simply want a richer way to read sacred texts, this conversation offers thoughtful insight and plenty to ponder.
