I have figure a way out of all your current "problems" simple - just do this:
#1 - Announce all mistakes you have made for the past 100+ years
#2 - Connect this "confession" with the fact that Moses also made grave mistakes along with the Hebrews, so was forced to wander around in the desert for 40 years.
You guys are so good, you could definitely "link" these events with current events - you've been doing stuff like this for years!!! On top of that - the 40 years could be "prophetic" - so this "new light" could last decades and make everyone feel really bad & guilty! And, even if you "go under", you could still link that to the fact that Moses never got to see the promised land - he died at the entrance. That way, you could totally break off into little sects (i.e. different corporate names) and link this to the leaders that surely took up moses place after he died.
Okay, I think I've given you some decent groundwork here - so chop chop to work with you. I don't want any credit for this "new light" - but if you do choose to quote the source - just say it was me "Pettygrudger".
