I think that the idea's taught by the WTBTS lead inevitably to people adopting them. So for instance the WTBTS divides humanity up into classes. There are the 144,000 class, and the other sheep. Then there are demon possessed people. Apostates. and people to witness to. People find for themselves a place within this heirarchy. I want none of it.
I personally think that if you believe in taking the wine and the bread in memory of Jesus then you are perfectly entitled to doing so. And you don't have to worry about it being an exclusionary doctrine.
Do you think the '144,000' (symbolic or not) are only jews or spiritual jews? ; Then who do you think the great crowd is.. I think it's going to be ;people from every walk of life and every religion..even atheists..with the good and honest .
I actually believe that Revelation (as with the rest of the bible) cannot be trusted as a document, since no original document survives - in legal terms it is hearsay. I don't put any faith in it.
I listen to the words ascribed to Jesus but I recognise that they have been adulterated. I believe that Jesus teachings, - turn the other cheek, love thy enemy, are worthy of following because they live and breathe life. I am awed by them even right now as I think about it.
