Reniaa...why do you feel the need to deflect from the question. To say we are bringing up dates and that these are irrelevant seems a bit insincere. The reason 1919 is important is that it is the basis for the authority of everything else the WTBTS speaks to. Again, is this appointment as God's channel on earth a fact because they say it is?? As Besty points out...if you don't accept the unique teachings of JW's (including 1919), you can't be one of them. Acceptance is not optional...approved association requires COMPLETE acceptance.
I have to say, that if you were trying to bring me around to your point of view with these non-linear lines of reasoning, you would lose me to frustration. I feel like you are a politician speaking double-talk without ever directly answering a question. Help me out here Reniaa!
