Groups run by former TWI leaders seem to hide in plain sight, at least as far as the general public goes. Whenever I give presentations about Undertow, there is usually someone in the audience who asks about what shape TWI is in today. I inform them about the succession of presidents, the sale of properties, the decline of loyalists. BUT I also let them know about spinoff groups that perpetuate Way-style doctrines, teachings, meetings, behaviors, while most of the time NOT mentioning their origins in Wierwielle's outfit.
Signs of that origin would be catch phrases like "the accuracy of the Word," which is something fabricated by VPW, or rather stolen by him from other fundamentalist Christian writers. Most audiences have never heard of Bullinger, etc., so the challenge is to encourage folks who are more than casually interested to acquaint themselves with fundamentalism, not only cults. The ideology of cults varies. The Bible-based cults can seem legit at first, but research on them may tell a different story.
Reactions to this news of TWI spinoffs range between disgust and nervousness. I recommend people ask probing questions about the origin of any group recruiter who approaches them and ask about finances and what checks are in place on the power of the leader, and for the name of the person who ordained him or her, etc.
All the above is just my two cents ... Why do I still care about all this? Like most posters here at GSC, I don't like to see people betrayed like I was.
