Once again Terry, a well written piece.
"Jehovah's witless claim God corrects them."
How does he do this? If he in fact does this, then why wouldn't he use this same method to allow them to get it right in the first place? The fact is, it is only from their own understandings, research, comparison's to other understandings and reflection that forces them to change things. They should not be printing anything without first having a complete conviction to being correct but they let so many other things influence their thoughts and none of that stems from God.
"3. God is not the author of confusion and yet what could be more confusing than being "in the Truth" and being wrong ?"
They will carry on about how unified they are and that they truelly are an organized organization and this proves they are the true religion because God is a God of organization. You make a good point here because their teachings are confusing and more so when they keep changing them.
