Perhaps before the most "evil and apostate" books to have is WT's old publications. A "religion" that their founder is considered to have "apostate" teachings according to WT's new understanding...Can you walked on the KH with the books of Russell(Study of the Scriptures)and give answers from those books?
Or can you take those books to a new Bible study? The answer is simply NO...You will considered an "apostate"and if you continue to use them you will be kicked out from the Organization...simple as that...
It takes a LOT of courage to open the gates of your mind. It takes a LOT of courage to explore and discover new things. Most of all it takes a lot of courage to USE your mind and have your OWN opinion in certain matters.
Jesus said that "light does not afraid of the darkness". If WT has the light then they have nothing to be afraid. But instead of accepting an honest invenstication of their doctrines, they send to hell anyone who dares to question them. It is the opposite of what Jesus said, that the "truth will set you free".
