Rosemarie:
The bottom line..is what the society teaches about the basic
doctrines....death, ressurecction.paradise earth.the kingdom. Armageddon
.....Etc is totally correct.....
Nope. Most JW beliefs, including their basic organisational structure, their view of the Bible and the general theme of their end-times dogma are derived from their Protestant origins via Adventism. (And the concept of a global paradise appears in the Bible exactly zero times.)
The few beliefs unique to JWs are pointedly false; most significantly, the doctrinal basis for their self-appointed claim of authority directly contracits the Bible.
At the foundation of JW theology relating to their claim of authority (see here) is their mishandling of the 70 years mentioned by Jeremiah. JW beliefs about the 70 years contradict what the Bible explicitly states about that period.
There are many additional problems as well. Feel free to ask.
