So your contention, CC23, is that the Church is being kept alive solely by Bishop Neal Webster? Because without bishops there is no Church, no apostolic succession. And if NFP, BOD and invincible ignorance are heresies, then all the bishops except him are heretics who are outside the Church.
I wonder if this fantasy appeals to some people; makes them feel special to be part of the last few. At any rate, the very least you should be doing is praying that Bishop Neal Webster has a nice long life.
By the way, if Bp. Neal Webster agrees with them, yes, they should seek him out and put themselves under his authority. If there are no bishops who agree with them, they can't be monks, as far as I understand it. Until I hear exactly who this "valid priest" was who they took vows in front of, that is.
I wouldn't agree with S2Srea that they're in it for the money. That may be rash judgment there, S2Srea. I think they probably believe in what they're doing and justify it to themselves, probably have fooled themselves into believing they have to do what they're doing.
