For a quick list of "characteristics of a cult or mind control organization," check out the book by
Dianne Wilson --- Awakenings of a Jehovah's Witness. She has one chapter that deals with that very topic. Very concise and lucid. I actually made my own file of those characteristics (on my home computer). I printed them up and read the list objectively and honestly. I checked nearly 95% of the traits when I evaluated the WTS. ( I would be happy to PM them to you this evening, if you like).
For a more in depth look at Cults, mind control, and intervention, Steve Hassan's book is the one to get -- Combatting Cult mind Control. It should help you with strategies for dealing with your dad, or any loved one in a cult environment. The author was a "moonie" before he came out. Dealing with cults and "deprogramming" is his specialty, or so it seems.
If you are looking for a quick reference to ALL of the false prophecies of the WTS, a quick index is Index of Watchtower Errors, 1879 to 1989, David A. Reed (Editor) --- available at amazon or barnes and noble. It reads easily, and is designed by topic.
Local libraries may well have these available...
False prophecy was a big thing for me. So much so that I paid big $$$ for some of the old Studies in the Scriptures volumes. I wanted to verify that the prophecies that were listed indeed were published by the WTS.---- thery were -- every one that I referenced to the ORIGINAL source material checked out.
The WTS hangs themselves with their own noose. No need for "apostate" literature. They discredit themselves with their own publications.
