I remember at a book study the conductor saying something about ho simple everything was and that anyone of us could easily talk for a minute about our beliefs.
Everybody froze of course and was hoping he wouldn't pick them.
No one could or wanted to do it even amongst each other !
It's a sad indictment of the 'faith' isn't it. I have a theory that 90% of JW's could not tell you what the current beliefs were. You'd just get a few stock phrases about blood, 1914 and generation which would be out of date anyway.
