If God is unchangeable and would not lie then either the angels were:
1. very careless and unreliable in bringing their messages to the governing
body and the writers of The Watchtower, (Can we believe God would pick such
messengers and allow this to happen?)
2. they were actually evil deceiving angels passing on erroneous messages to
confuse people. (Again could you believe that God would not be able to
recognize this and check them out before passing on Godly information to his
anointed followers on earth?)
3. it was a totally man made theory to try and give credibility to their
peculiar doctrines presented by the President and the leadership of the
Society.
4. or, a satanically inspired scheme to mislead the leadership and their
followers.
I think we would have to choose between these last two options.
There are no other sources.
