A Busan megachurch pastor’s political sermons turned into an election law case, a jail stint, and a rare public split inside his own denomination.
A South Korean pastor known for mixing Sunday sermons with hard-right politics has become one of the country’s most talked-about religious figures — not for a miracle or a mega-donation, but for a criminal conviction. Pastor Son Hyun-bo, senior pastor of World Mission Church in Busan, was arrested, jailed for roughly five months, and later convicted of violating South Korea’s election law. His case has split his own denomination down the middle and drawn attention as far as Washington, D.C.
Here’s what’s actually going on, explained for readers outside Korea.
Who Is Son Hyun-bo?
Son Hyun-bo leads World Mission Church (세계로교회) in Busan, one of South Korea’s larger congregations, and heads a conservative Christian coalition called Save Korea. The group became prominent during the political turmoil surrounding former President Yoon Suk-yeol, organizing large rallies that defended Yoon’s martial law declaration and opposed his impeachment. Critics inside and outside the church describe Son as having built a media-savvy, YouTube-driven political brand — some commentators have compared his rise to that of far-right pastor Jun Kwang-hoon.
Son also has a prior legal history: during the COVID-19 pandemic, he was prosecuted for repeatedly holding large in-person services in defiance of public health orders, drawing hundreds to thousands of worshippers at a time between September 2020 and January 2021. That case wound through the courts for years and ended with a finalized fine in early 2026.
What Is Son Hyun-bo Accused Of?
The bigger case — the one driving current headlines — centers on South Korea’s Public Official Election Act, which bars religious leaders from using their official role inside a religious organization to campaign for or against a candidate.
Prosecutors say that around South Korea’s 2025 presidential election and a separate Busan education-superintendent by-election, Son used church services and prayer meetings to:
- Publicly back a conservative presidential candidate and criticize his rival during sermons and prayer gatherings attended by hundreds to nearly 2,000 congregants
- Interview a conservative education-board candidate from the pulpit and hold a rally at that candidate’s campaign office urging his opponent’s defeat
Under Korean law, this kind of activity — campaigning through a position of religious authority — can carry up to three years in prison or a fine of up to 6 million won (roughly $4,300).
The Arrest and Trial Timeline
- September 2025: Prosecutors sought an arrest warrant; a Busan court granted it, citing flight risk, and Son was jailed pending trial.
- January 30, 2026: The Busan District Court convicted Son on all counts, sentencing him to six months in prison, suspended for one year — a verdict that freed him immediately after roughly five months in detention. Prosecutors had sought a full one-year prison term.
- February 2026: Son’s legal team filed an appeal, arguing the case should never have been treated as a crime and signaling plans to challenge the constitutionality of the underlying election law provision.
- 2026, ongoing: The appellate trial is underway, with witness hearings scheduled through mid-2026. Son continues to argue the prosecution amounts to political retaliation.
The judge in the first trial pointed to Son’s reach — congregation size plus a large YouTube following — as evidence he wielded real influence over voters, concluding he intended to help elect one candidate and defeat another.
Why the Church Is Divided
What makes this story unusual isn’t just the criminal case — it’s the reaction inside Son’s own denomination, the Presbyterian Church of Korea (Kosin), a conservative Presbyterian body.
Denominational leadership sided with Son. Kosin’s general assembly leadership called his arrest a “signal of political persecution against the entire Kosin church” and pledged to resist what it called excessive law enforcement.
Many rank-and-file pastors and elders pushed back hard. A group calling itself “Church Members Who Love Kosin” held a press conference outside the denomination’s headquarters demanding Son be formally disciplined, arguing he’d turned Sunday worship into a political rally and damaged the church’s credibility. A Protestant watchdog group, the Church Reform and Practice Solidarity, went further, publicly criticizing Kosin’s leadership for defending someone it says clearly broke the law.
The dispute reflects a broader argument playing out in Korean Protestantism: how far a pastor’s political speech can go before it crosses from “religious conviction” into unlawful campaigning — and whether framing a conviction as “religious persecution” undermines the credibility of Korean churches more broadly.
The Trump Visit and U.S. Angle
After his release, Son traveled to the United States and met with President Trump and Republican political figures, telling supporters that American backers — including, he claimed, roughly 10,000 signatories and a U.S. pastor network — had rallied behind him. He has also said U.S. officials suggested his continued freedom in Korea, though details of these conversations haven’t been independently confirmed.
Back home, this drew criticism even from some conservative Christian commentators, who argued that promoting his case abroad while a criminal appeal is pending — and while he continues to describe a lawful conviction as “religious persecution” — was inappropriate.
What Happens Next
Son’s appeal is ongoing, with his defense team pursuing a constitutional challenge to the election law provision itself. If the appellate court or Constitutional Court sides with him, it could reshape how far Korean courts allow religious leaders to go in political speech from the pulpit — a live and unresolved question in South Korean law. If the conviction is upheld, it would reinforce existing limits on clergy campaigning that prosecutors say Son knowingly crossed.
