Please describe what you read in the letter that shouldn't be present in Daniel chapter 11. I'm curious because I still attend but have doubts.
Did you know in 1964 they believed the original serpent had limbs. Then the new leadership in 2007 decided the old leadership was wrong and said it didn't. They were in Watchtower articles in the "Questions from Readers" section. There's actually pictures of it with limbs in the book, "New Heavens and a New Earth" published in 1953, page 81.
If there was time machine and the old leaders came to greet the new leaders the new ones would be disfellowshipped in a heartbeat due to all the changes they made.
