Following the release of the Netflix documentary "In the Name of God: A Holy Betrayal" and a growing public outcry against Jesus Morning Star (JMS) and its leader Jeong Myeong-seok, some doctors have expressed concerns about the possible impact on their business.

"In the Name of God: A Holy Betrayal" is an eight-part documentary that tracks four self-proclaimed messiahs and the events and people behind them in South Korea's modern history. The first three episodes covered JMS and its leader Jeong.

Since the broadcast, citizens have been sharing how to identify institutions possibly affiliated with JMS, including churches, clinics, and restaurants, as the show showed that most of the victims had unintentionally encountered JMS in their daily lives.

The most famous JMS distinction method spreading online is the so-called “Jeong Myeong-seok font.”

According to Korean netizens, the font shows long strokes under every letter.

Churches, restaurants, clinics, and academies that have used the font on their signages are surfacing online, mostly on blogs. 

Some clinic-owning doctors have expressed concerns as the list includes a significant number of clinics with signs that appear to be written similarly to Jung's handwriting.

The doctors stressed that some of the clinics on the list might face repercussions even though they have no affiliation with JMS because they used the font by mistake or used a similar font.

Online doctors’ communities have advised members to take precautions, saying they need to check the font of their clinic signages to prevent possible damage.

Meanwhile, the medical community expressed shock after Kim Do-hyung, a professor of mathematics at Dankook University who has been tracking JMS for 30 years, revealed that JMS members include doctors and medical professors at university hospitals.

In an interview with JTBC, a nationwide pay television network station, Kim said that a gynecologist who was a member of JMS tampered with evidence during the investigation into Jung's sexual crimes, making it impossible for the victims to tell the truth.

"In 1999, when law enforcement agencies first began investigating Jeong Myeong-seok's sex crimes, there was a female follower who was believed to have had sex with Jeong," Kim said. "However, the gynecologist performed a hymen reconstruction surgery on a victim of Jeong Myeong-seok's sex crimes without leaving any medical records."

The woman went to a university hospital and received a medical certificate stating that her hymen had been observed, and the case was dropped, Kim added.

Kim also recalled how his father was terrorized for his activism and testified that even a plastic surgeon at the university hospital where his father was scheduled to undergo surgery was a JMS member.

"After JMS members attacked my father, he was taken to the emergency room of a university hospital in Gyeonggi Province, where he was scheduled to have surgery by a plastic surgeon, who was also a JMS member," Kim said. "The situation was horrifying."

Kim also stressed that he suspected the doctor intentionally wrote a medical certificate that understated the degree of his father's injuries.
