When I first heard about this group, I thought it was a front group for the Moonies. Then I thought the people who started it were former Moonies who decided to start their own group (cult).
from wikipedia (9/8/10)
"The World Mission Society Church of God (Korean: 하나님의교회 세계복음선교협회) was founded by Ahn Sahng-hong (안상홍) in 1964. The church believes that he is the second coming of Christ. Ahn Sahng-Hong was baptized in 1948 and died in 1985 and the current leader of the church is Ahn's spiritual wife, Zang Gil-Jah (장길자), known in the church as "the Heavenly Mother", and the General Pastor is Kim Joo-Cheol."
I shot this video in July 2010 of Professor Tark at a conference where many former members of a wide variety of destructive, totalitarian groups met. I had never heard of Professor Tark, but came to learn that his father was the mosst famous anti-cult minister in Korea. He was unfortunately assassinated by a cult member (not someone from WMSCOG). He is professor of Religion at Busan Presbyterian University. His web site, unfortunately only in Korean is hdjongkyo.co.kr
