Orthodox Conundrum

Zohran Mamdani - a politician who openly rejects Israel’s right to exist as a Jewish state, yet insists that this has nothing to do with antisemitism - is now the mayor-elect of New York City. He points to a small number of Jewish supporters as evidence, while promoting a worldview in which Israel is framed as a genocidal, apartheid project. New York is home to the largest Jewish community in the diaspora. When that city elects a proudly anti-Zionist mayor, it sends a message far beyond one municipality. It raises hard questions: What does it mean for Jewish security, for public discourse...

Mamdani, Fuentes, Tucker, and Mainstreaming Antisemitism: Jonathan Greenblatt on the Growing Threat from the Left and the Right (268) show art Mamdani, Fuentes, Tucker, and Mainstreaming Antisemitism: Jonathan Greenblatt on the Growing Threat from the Left and the Right (268)

Orthodox Conundrum

In recent weeks we have watched something many of us hoped we would not see in the United States: openly anti-Zionist and even openly antisemitic voices moving from the margins into the mainstream. Zohran Mamdani’s victory in New York raises the chilling possibility that hostility to Israel is now an electoral asset. At the same time, parts of the American right are flirting with figures like Nick Fuentes, a Holocaust denier who says Jews do not belong in Western civilization. To make sense of this moment, I spoke with Jonathan Greenblatt, CEO and National Director of the Anti Defamation...

Charedi, Dati Leumi, Modern Orthodox, Traditional, Secular: Is Jewish Unity Even Possible? A Conversation with Rav Yosef Zvi Rimon (267) show art Charedi, Dati Leumi, Modern Orthodox, Traditional, Secular: Is Jewish Unity Even Possible? A Conversation with Rav Yosef Zvi Rimon (267)

Orthodox Conundrum

Is Jewish unity even possible? In this urgent episode Rav Yosef Zvi Rimon faces the hardest questions raised by the draft crisis and by the widening gaps between Charedi, Dati Leumi, Modern Orthodox, Traditional, and Secular Jews. He explains why unity is not a slogan but a practical necessity and religious obligation with real consequences for security, community, and our shared future. With clarity and empathy he maps a path for principled disagreement, mutual responsibility, and practical steps that families, shuls, and schools can take right now. If you are tired of talking points and want...

The World is a Beautiful Place... and We Need to Earn It: Talking About The Morning After with Dr. Erica Brown (266) show art The World is a Beautiful Place... and We Need to Earn It: Talking About The Morning After with Dr. Erica Brown (266)

Orthodox Conundrum

What does the morning after really look like... when the dawn reveals not only light, but rubble and work? In this deeply personal conversation, Scott and Dr. Erica Brown ask how we craft a vision of where we’re going when optimism feels naïve, unity is fragile, and joy and grief insist on sharing the same space. Drawing on Rabbi Sacks’s distinction between optimism and hope, they explore how to build active hope through autonomy, giving, and purpose. They define Jewish unity as purposefulness rather than groupthink, wrestle with isolation and rising antisemitism in the diaspora, and...

Seven Facets of Healing: Rabbi Leo Dee’s Blueprint for Jewish Resilience (265) show art Seven Facets of Healing: Rabbi Leo Dee’s Blueprint for Jewish Resilience (265)

Orthodox Conundrum

This episode is dedicated to the complete recovery of יהונתן איתן בן בת שבע ברכה. How do we move from private anguish to collective strength? In this deeply personal and wide-ranging conversation, Rabbi Leo Dee shares the story of the day his wife and two daughters were murdered, and the seven-facet framework he built to keep living with faith and purpose. We walk through Family, Friends, Fitness, Frumkeit (spiritual life), Function (purpose), Finances (trust and control), and Fun (simcha/growth)... first as practices for an individual in pain, and then as a national...

Eulogies and Boundaries: Orthodox Jews and the Legacy of Charlie Kirk (264) show art Eulogies and Boundaries: Orthodox Jews and the Legacy of Charlie Kirk (264)

Orthodox Conundrum

Charlie Kirk’s assassination is a shocking, tragic act of violence. Murder is a desecration of the image of God, full stop. We condemn it unequivocally, and we pray for comfort for his family and for all who were harmed. At the same time, Charlie Kirk was a complicated public figure. He was outspokenly pro-Israel and often advocated for Jewish safety; he also voiced criticisms of Israel’s current government. He advanced positions that many in the Orthodox world consider essential, and others consider deeply problematic. He defended Israel vigorously, and he also gave a platform to voices...

God's Loyal Opposition: Anger, Faith, and Divine Confrontation, with Rabbi Dr. Raphael Zarum (263) show art God's Loyal Opposition: Anger, Faith, and Divine Confrontation, with Rabbi Dr. Raphael Zarum (263)

Orthodox Conundrum

Is it possible—maybe even Jewish—to be angry at God? From Abraham’s challenge at Sodom to Job’s cries of despair, Tanach is filled with voices that confront the Divine. But what does that mean for us today, when we struggle with personal tragedy, global antisemitism, and the ongoing pain of the seemingly endless war against Hamas? In this wide-ranging conversation on the Orthodox Conundrum, Scott Kahn speaks with Rabbi Dr. Raphael Zarum, Dean of the London School of Jewish Studies, about whether anger at God is heresy or a profound act of faith. Along the way, they discuss biblical...

Suppressed, Rediscovered, Essential: Rav Kook’s Lost Guide for Modern Faith (262) show art Suppressed, Rediscovered, Essential: Rav Kook’s Lost Guide for Modern Faith (262)

Orthodox Conundrum

This episode is partially a detective story, partially an analysis of daring ideas, and partially an invitation to discover new methodolgies of confronting challenges to Orthodox Judaism. Rav Kook drafted L’Nevuchei HaDor over a century ago—then the manuscript largely disappeared from view, resurfaced piecemeal, and sparked debates about redaction and “censorship.” In this follow-up to our popular episode with Professor Marc Shapiro, I speak with Rabbi Aryeh Sklar, translator of the new English edition, to unpack both the history of the text (why it was sidelined, what changed between...

Learning Tanach Daily Through 929: Opportunities, Challenges, and Dangers, with Rabbi Benny Lau (261) show art Learning Tanach Daily Through 929: Opportunities, Challenges, and Dangers, with Rabbi Benny Lau (261)

Orthodox Conundrum

As one 929 cycle ends and the next begins, Scott talks with Rabbi Benny Lau—founder of 929—about why the project started, what it hopes to change in Jewish life, and what a shared, chapter-a-day cadence can build across communities. They also tackle the harder questions: the risks of using Tanach as a direct guidebook without the mediating lens of the Oral Tradition, how to engage ethically with challenging passages, and where pluralism meets red lines. Practical takeaways included: how beginners can start this week, and what to do when you fall behind. Whether you’re all-in on 929 or...

Orthodox Parents and Their LGBTQ Children, with Rabbi Yakov Horowitz (260) show art Orthodox Parents and Their LGBTQ Children, with Rabbi Yakov Horowitz (260)

Orthodox Conundrum

When a child shares something deeply personal about his or her sexual orientation, Orthodox parents can feel love, concern, and uncertainty all at once. In this conversation, Rabbi Yakov Horowitz reflects on what he’s learned working with families and communal leaders: how to approach the first conversations, which words can prevent hurt, and where halacha and mesorah guide our choices. We also consider what he’s heard from senior rabbinic figures, how different communities navigate these moments, and what hope might look like over time. This is a tender, honest discussion meant to help...

Can science be a vehicle to get closer to God? The Rambam famously answered in the affirmative. In the second of the 1000 chapters of his Mishneh Torah, Hilchot Yesodei HaTorah chapter 2, the Rambam writes, “What is the method towards loving and fearing God? At the moment that a person investigates His wondrous and massive actions and creations, and sees through them His endless and infinite wisdom, he immediately loves, praises, and extols, and desires tremendously to know the great Name. In the words of David, ‘My soul thirsts for God, the living divine.’ And when he thinks about these things themselves, he immediately recoils backward and is awestruck and fears, realizing that he is a small, lowly, and beclouded creature, with minimal and superficial knowledge compared to God’s perfect intellect. As David said, ‘When I see your heavens… what is man that You should acknowledge him?’ According to these ideas I will clarify important principles of the works of the Master of the worlds so that they will be an introduction to one who understands in order to love God. As the Sages said with regard to love, from this you recognize the One who spoke and the world came into being.” The Rambam then proceeds to give an introduction to the Aristotelian world view that was presumed true in his time. While we no longer accept the Rambam’s science as accurate, his principle that knowledge of the universe is a vehicle to loving and fearing God remains an essential principle.

What about using science to demonstrate God’s existence? The Rambam, again, was willing to use philosophical arguments for this purpose; but others recoil from the concept. Many people have no interest in examining theories such as intelligent design and creationism, and find them absurd. There’s a different but somewhat similar phenomenon which Professor David Shatz calls “bold concordism,” where scientists attempt to demonstrate that the first chapter of Bereshit and modern physics are in complete agreement, as long as the words of the Torah are read in a literal, albeit non-obvious way. Some people find this inspiring and helpful, while others dismiss it altogether.

My guests today, Rabbi Aaron Zimmer and Rabbi Dr. Elie Feder, propose something quite different. They use established scientific facts based on up-to-date physics - scientific facts, that is, which no one denies - and argue that the most logical conclusion from this science is that the universe was created by an intelligent designer. This has nothing to do with the argument of intelligent design from biology, and is not based on any verses in the Torah. It doesn’t even deal with questions around divine providence or other aspects of Jewish belief. Instead, they argue that modern physics has offered a brand new and extremely compelling version of the argument from design: that the values of the constants are so unusual and so inherently unlikely, that the most obvious conclusion by far is that they were designed so that our complex universe, which includes atoms, molecules, stars, galaxies, and life, would come into existence. As they explain, almost all serious physicists were bothered by the problem of why the constants are what they are; physicists almost universally acknowledge that the reason that the constants have the values that they do is a huge mystery. Elie and Aaron only differ with most other physicists in that many others try to solve this mystery by positing the existence of a multiverse - that is, infinitely many worlds, each with different values of the constants; whereas my guests argue that this is far more unlikely than the obvious answer: that something with intelligence chose these constants for a reason.

Regardless of whether you like the idea of using science to demonstrate God’s existence or disagree with the enterprise, Elie and Aaron’s argument demands serious attention. I’m honored to present it today, and look forward to hearing what you think.
