NEW YORK — Comedian and SiriusXM host John Fugelsang is taking direct aim at Christian nationalism in his New York Times bestselling book “Separation of Church and Hate”, released Sept. 9, 2025. He argues the movement doesn’t need more slogans — it needs a closer reading of Jesus, Dec. 15, 2025.
Part political critique, part Bible study, the book frames Christian nationalism as a bait-and-switch: Christianity’s language, stripped of Jesus’ ethics, repackaged as culture-war permission. Fugelsang, the son of a former Catholic nun and a Franciscan brother, writes for believers and skeptics who are tired of watching scripture get used as a cudgel — and who suspect the loudest “Christian” voices in politics aren’t always the most Christ-like.
Christian nationalism is the target — and the test
In Fugelsang’s telling, Christian nationalism isn’t simply “religion in public life.” It’s a power project that borrows Christian identity while sidelining the harder parts of Jesus’ message: humility, mercy, care for outsiders and resistance to cruelty. In a recent interview, he put it this way: “Jesus is on your side, whether you believe him or not.”
And it isn’t a fringe conversation. The Public Religion Research Institute reported that in 2024, about three in 10 Americans qualified as Christian nationalism “adherents” or “sympathizers,” with attitudes largely stable since late 2022.
How Fugelsang builds his case
Fugelsang doesn’t write like a professor. He writes like someone who’s argued with a relative online — and came prepared. A recent review described the formula as pairing extremists’ stated beliefs with Christ’s words, then letting the contrast speak for itself.
He tackles abortion, immigration, LGBTQ rights and guns by contrasting modern talking points with the passages people cite in God’s name.
He treats Christian nationalism as a Bible problem, not just a politics problem — and urges readers to debate with scripture, not vibes.
He’s funny on purpose: the jokes aren’t decoration; they’re a way to keep a heavy argument readable.
The long argument over Christian nationalism
Fugelsang’s book arrives after years of warnings — and plenty of confusion over what the label means. A 2022 Pew Research Center survey found 45% of U.S. adults said the country should be a “Christian nation,” even as large majorities said houses of worship shouldn’t endorse candidates or wade into day-to-day politics.
That same year, UC Berkeley scholars warned that Christian nationalism can harden into an exclusionary identity politics that treats democratic compromise as a spiritual threat. Meanwhile, a Yale-led conference pushed for clearer definitions, drawing a bright line between patriotism (loyalty to shared ideals) and nationalism (loyalty to “your tribe”).
By 2023, Interfaith America writers were tracking how the surge in attention around Christian nationalism accelerated after the 2016 election cycle and Jan. 6 — and urging more precision about what the term includes, and what it doesn’t.
The bottom line
Fugelsang’s message is less “don’t be religious” than “be honest about what you’re worshipping.” If the politics being sold in Jesus’ name looks nothing like the Jesus described in the text, he argues, it isn’t faith — it’s branding. And that’s why, in his view, Christian nationalism collapses the moment readers stop outsourcing belief to the loudest voices and start checking the receipts.
