How would you suggest one go about proving the existence of invisible beings? Actually I'm sure you have a few watching you this very minute but they wouldn't want to blow their cover with you since it benefits them not to be believed in.
I can only guess that you're talking about demons. Of course it would also apply to your God. How does it benefit Him to not be believed in?
That lots of intelligent sane people describe them to you really ought to count as a good enough reason to think there might be something to it....
No, that isn't how the brain works. It is possible to be intelligent and sane in some parts of your brain while holding silly thoughts in another part. What distinguishes blind believers is their inability to assess their own thoughts for silliness.
There's a good reason why we often ask each other, "Did you see that?" Our social connections help us to filter out the individual silliness.
I can't even figure out how anyone calls mainstream Protestant traditional Christianity a "cult."
I have said somewhere else what I consider a cult to be: a group that considers itself (its leaders) the authority on everything, that discourages its members from looking/learning outside the group, that cites "authorities" rather than evidence. You certainly fit that description, as do the Moonies, Jehovah's Witnesses, etc.
The list of well known Christians in Message 777....
I have pointed out to you before that you have cited Catholics as authorities. Do you relly want that list scrutinized? I suspect we would find people on it who disagree with you.
You are the one inventing a "fixed dogmatic" doctrine, not I.
On the contrary, you're the one who insists that all truth comes from the Bible - but not from what the Bible actually says, only what your "orthodox authorities" say it says. To me that describes a cult.
