How I believe it should be.
Loosely organised with congregations being autonomous. No rigidity in either beliefs or purpose. The unity should be love based and not works based. No heirachy. All are merely brothers with only Christ as Master.
No one should be penalised or castigated for having different views. Elders should have far less to do, the red tape should be got rid of and brothers and sisters should be free to live their lives as they wish, according to their own bible based consciences. Elders should be there to be real shepherds, looking after the physical needs of the sick, elderly and destitute. Spritual needs should be cared for in a non legalistic way.
Unscriptural beliefs as far as I see it:-
Jesus is mediator of ALL and not of only 144,000.
Great Crowd are a heavenly group (all christians)
Emblems are to be partaken of by ALL christians
8 billion people are NOT going to die at Armageddon. It will not be only JWs who are saved.
The 'other sheep' are gentiles. The little flock are 1stC christian jews.
Baptism questions are totally wrong now.
Jesus became king in 33CE and not 1914
When he comes again it will be visible and not invisible
Overlapping generation is a farce
607 BCE is totally wrong.
The 'faithful and discreet slave' is a parable and not a prophecy. (Just like the slaves with the talents)
No single group of brothers should be above their other brothers.
There are many other things I think should be changed. However, I can't see it ever happening!
