Did Jesus Really Change Western Morality? Bart Ehrman

How much of what we call "basic morality" is actually inherited from Christianity? Bart Ehrman joins Michael Shermer for a wide-ranging conversation about one of the biggest moral questions in history: why do we feel obligated to care for strangers at all? Drawing from his new book Love Th

Topics Discussed

Episode Summary

Executive Summary: The conversation centers on Bart Ehrman’s claim that Jesus was an apocalyptic Jewish preacher whose teachings on repentance, forgiveness, and care for strangers helped reshape Western moral norms. Ehrman contrasts ancient kin-based ethics with Jesus-inspired altruism, traces how Christianity institutionalized charity, and critiques modern political uses of the Bible on immigration, abortion, slavery, and social welfare.

Main Topics: Bart Ehrman’s intellectual and religious journey (Priority: 5/5): Ehrman explains how studying Greek, Hebrew, and biblical textual history moved him from evangelical inerrancy to liberal Christianity and then atheism/agnosticism, with suffering as the decisive issue. Jesus as an apocalyptic preacher (Priority: 5/5): The discussion argues that Jesus expected the end of the age soon, preached repentance for imminent judgment, and did not teach a long-term social ethic in the modern sense. Altruism vs. kin-based morality (Priority: 5/5): Ehrman frames the book around why humans help strangers, contrasting evolutionary explanations and ancient moral systems that favored family, tribe, or civic insiders over outsiders. Christianity’s moral legacy in the West (Priority: 5/5): Ehrman argues that institutions like hospitals, orphanages, disaster relief, and charity for the poor emerged from Christian teachings and altered Western conscience over centuries. Biblical interpretation and political weaponization (Priority: 4/5): The speakers challenge modern claims that the Bible straightforwardly supports anti-immigration, anti-abortion, anti-government welfare, or conservative political positions. Atonement, forgiveness, and the post-Jesus church (Priority: 4/5): They distinguish Jesus’ message of forgiveness from later Christian atonement theology, arguing that early followers transformed his teaching after his death and resurrection beliefs. End-times culture and failed predictions (Priority: 3/5): The discussion covers rapture date-setting, including the 1988 prediction craze, as an example of how apocalyptic belief shapes ethics and politics even when predictions fail.

Key Arguments: Jesus was historically an apocalyptic Jew, not a teacher of long-term personal happiness or modern social ethics. Most ancient moral systems emphasized helping kin, civic members, or socially defined insiders, not complete strangers. Ehrman argues that Jesus’ command to love and aid strangers helped create a broader moral circle in the West. The earliest Christians shifted from Jesus’ message of forgiveness to a doctrine of atonement, making Jesus’ death central to salvation. Modern Christians often read the Bible selectively, using it to justify positions that are not actually supported by the text. Public hospitals, orphanages, and organized charity in the West were Christian innovations that institutionalized concern for the vulnerable. Apocalyptic belief can distort present-day priorities by making people discount climate change, social policy, or long-term planning.

Data Points: Copies circulated of end-times book: 2 million - Discussing 88 Reasons Why the Rapture Will Occur in 1988 Predicted rapture date: September 1988 - The book’s author claimed the rapture would occur that month Biblical passages referring to abortion: 2 - Ehrman says the Bible contains only two relevant passages Years since conversion to atheism/agnosticism: About 35 years - Ehrman dates his shift away from belief to roughly 35 years earlier Languages studied for biblical scholarship: Greek, Hebrew, Latin, Aramaic - Needed to read texts in original languages and pursue advanced scholarship Translated languages for Ehrman’s books: 27 - His books have been translated widely Copies and courses sold: Over 2 million - Combined sales of books and Great Courses audio/video programs Bible books in the New Testament: 27 - Ehrman’s next book will analyze how the canon was formed Timing of public hospitals in the West: Middle of the 4th century - He says they were Christian inventions and can be dated historically Generational calculation used by rapture interpreters: 40 years - Applied to 1948 plus 40 to reach 1988 in end-times speculation

Pivotal Quotes: "No one knows the day or the hour, I just know the week." — Bart Ehrman (relaying the 1988 rapture predictor): Used to illustrate failed date-setting in apocalyptic Christianity "It takes a while to do it. Yeah, yeah, yeah." — Bart Ehrman: On how Jesus’ ethics of caring for strangers gradually became part of Western moral intuition "You're not reading it. That's that idea." — Bart Ehrman: On modern politicians and believers using the Bible selectively to justify preexisting views

Implications: The episode suggests Western moral norms are deeply shaped by Christianity even for nonbelievers, while warning listeners against proof-texting scripture for politics. It also shows how apocalyptic belief can distort ethics, policy, and historical interpretation.
