Excellent thoughts, Maksym. If God has always had a faithful slave class, who each pass the baton of knowledge to another generation, with which members of the faithful slave class did CT Russell consult when he created his new and unique set of beliefs? Isn't it true, then, that the doctrines of JW, which evolved from his teachings, are based on the thoughts of one man? (and what does their bible say about putting faith in man?)
Furthermore, in 1917 Russell's successor, JF Rutherford, removed four of the seven members of the Watch Tower Society board of directors because they tried to stop him publishing an article with a doctrine that contradicted the religion's doctrine. By overriding the wishes of the majority, wasn't he again forcing on the organisation his own personal view? Wasn't he challenging the governing body of the time .... and if so, what does that mean about all those doctrines he introduced (Armageddon, the "torture stake", a birthday ban, the concept of God's "organisation", the requirement for all JWs to go witnessing, the blood ban ....) maybe they are all doctrines God disapproves of?
Here are a few more lines of thought if a Witness calls.
1. "You must meet a lot of people from different religions when you call door to door. Do you find many people remain in a religion only because they have never really examined it?" (they'll say yes.) "That must be so frustrating for you! Those people are just blinkered. But what about you? Would you ever read a book or website that criticised or analysed your religion ... or do you restrict your reading to just what your leaders tell you?"
2. "What would I have to do to become a JW?" (you study, attend meetings, get baptised.) "If I went through that process and later decided for whatever reason -- growing knowledge, for example -- that I had made the wrong decision and resigned, what would be the consequences?" (they'll say you can just leave freely.) "But say you and I had become close friends, or my relatives also joined, but stayed in the religion when I left. Would you still talk to me ...or would you be prevented from talking to me? If I still believed in God and Christ, wouldn't I still be a Christian? Why would I be shunned? Isn;t that just a cult control tactic?"
3. "Where do JWs get their doctrines? I've heard there's a faithful slave. What's that? Who is he?" (they'll explain). "Ah, so someone in your own congregation could be a member of the slave class? If God's using him or her, and that person thought very deeply and decided a JW doctrine was wrong, would the Governing Body listen to them and consider changing the doctrine? What if 10 or 100 anointed JWs all wrote to the Governing Body and said this doctrine is wrong; that the teaching of the 144,000 being a literal number is wrong; that the prohibition on blood transfusions is wrong; that when Jesus spoke about the other sheep he just meant Gentiles? Would the Governing Body listen to them?"
