I tried to research this cult, Shincheonji, a little(!) bit:
Unknown regarding their leader & the virus.
The cult has over 120,000 members. Something tells me they are NOT mostly out in the villages in the hills. (This outbreak is in SK’s 3rd largest metro area.)
Once converted, members are said to spend less time with friends and family, neglect work, etc., but OTOH they proselytize a LOT. How much intra-cult socialization they do I could not find good info. on, but they do apparently hold a “Shincheonji National Olympiad” in Olympic Stadium, South Korea - how often, I don’t know.
To what extent the group might or might not cooperate with medical personnel, report illnesses, contacts, etc., I haven’t a clue. Hopefully they do not have a sense of being persecuted by the gov’t, and / or get persecuted by “non-believers” - that could make things very bad.
Is this trouble? I honestly don’t know. Not enough info. I’d guess there is a small chance this could blow up.
The ministry is warning military not to attend services. I hope our military warned them to stay clear of these people a long time ago.
