the resolution of this question will have to be a little subjective, my hope is it will be resolved YES if it seems people still believe the core beliefs (probably mainly that Ahn Sahng Hong is the second coming of christ, Zahng Gil-jah is God the Mother, your soul is saved by participating in passover, etc.) 20 years after the death of Zahng Gil-jah even if they go by a different name or have new additional beliefs. other wise should resolve NO. feel free to ask other questions in the comments.
