I first met Ed Gruss in 1981 when I was writing up my tract, "What Happened at the World Headquarters of Jehovah's Witnesses in the Spring of 1980?" and we became good friends. His now out-of-print book, "Apostles of Denial" was the first comprehensive study of the JWs by an ex-JW in 1970. Now, he has published the most comprehensive book on the JWs printed to date, entitled,
"Jehovah's Witnesses: Their Claims, Doctrinal Changes and Prophetic Speculation."
I know it is the best because I got to help proofread it. A must have for anyone wanting a good book on history and the JWs. Check it out!
