large number of articles promoting traditional Chinese mythology and Biblical storiesI don't think the Chinese edition contains a significant amount of Biblical stories in any sence. Maybe Falun Gong stories'' is a better term. 

Actually they refered to the CCP as the anti-Christ and that the CCP will be destroyed by "God". I didn't know Falun Gong worshipped a god. 

maybe they were refer to Li Hongzhi, but I am not sure because they have their own definition of Christianity. 

Falun Gong practitioners don't worship anybody, Li Hongzhi included (or at least they're definitely not supposed to, or they're not following the teachings of Falun Gong!).

Based on what I've read and heard from practitioners' perspectives, I don't think that practitioners mean that Li Hongzhi will destroy the CCP as "God," although he certainly seems to play that role in many regards.  I think in general practitioners believe that given the nature/laws of the universe, heaven, earth, today's society, etc, or however you wish to express everything that is relevant to us currently, put together with the past and present of the CCP, the CCP cannot survive and will (and is) destroying itself.
