Was reading up on the World Mission Society Church of God, or WMSCOG for short, a South Korean Church founded in the early 60s by Ahn Sahn-hong. The church has a million+ members in over 100 countries. They believe in God the Father (Jehovah) and a God the Mother, whom they claim to be a living South Korean woman named Jan Gil-ja.
Like Watchtower, they claim to be the only church to have true understanding and interpretation of the bible. Other similarities include:
-They claim to have restored the truths of the Early Church
-No Christmas / Easter celebration
-Encourages it's members to preach door to door and in public spaces
-They offer bible studies
-No idols, including crosses, statues or even stained glass
-Has hinted at possible dates for the end of the world various times
While watching some of their propaganda videos, I found this one that attempts to discredit their ex-member community as a hateful Pharisee-like bunch, driven by emotion to speak lies against God's servants, as they claim has always happened throughout history. I found it interesting how similar their tone and logic is to Watchtower's. Substitute their use of the word "Church" with "Congregation" and you can almost say this is a video from JW.org
