At some point this arsehole will ask you the loyalty question, something like "But you do believe we are in God's organization don't you?"
it will come, in some form, over dinner, in front of witnesses, now, what do you do ? Lie ? O.K if you want to, but that doesn't get you anywhere, he will then ask you why you are not fully supporting God's Org. etc etc
DO NOT GO, as they used to say on the old maps "There be dragons"
