"It doesn't matter how good, how sincere, how much they help the poor, how much they believe in the bible, etc they are, if they aren't part of Jehovah's visible organization which the bible clearly says is through a faithful and discreet slave, then they will die at armageddon."
I think I would counter with: Can you show me anywhere that says the "domestics" must eat the food distributed by that slave or else die at Armageddon?
