Anyone know all the names of the cults that are under the umbrella of the Gu-Won-Pa?
I know that Good News Mission is one.
Four years later...
The name Gu Won Pa (Salvation Sect) has come up in relation to the sinking of the Sewol ferry. I've been gathering articles and information specifically about that here.
What does this have to do with Ock Soo Park and his groups? Well I'm not entirely sure, but it sounds like Park's groups (Good News Baptists/IYF etc.) and Mr Yoo's groups are both splinters of a cult that started in the 60s, splintering from a theological school run by American missionary Dick York. It is known as The Salvation Church or Gu Won Pa. Certainly the name Gu Won Pa (구원파) has been mentioned in the Korean press in relation to both men and their cults. And as Mr Esfes's question indicates, there are groups under the umbrella of the name Gu Won Pa.
There was one interesting mention of Mr Yoo about a month before the sinking which answers his question. Yoo is mentioned in this article:
Salvation Church (Park Ock-Soo Faction) International Youth Fellowship (IYF)
There are three factions in the Salvation Church. They are the Kwon Shin-chan (deceased)-Yoo Byeong-Eon faction, the Lee Yo-han faction, and the Park Ock-soo faction. All of them have been officially classified as cults by the main denominations of Korean churches.
