I did my own extensive research as I was getting out, and by exploring actual changes and mentions of core doctrine, I learned how it came about that the GB teach that only THEY know the truth and only THEY get holy spirit.
I was checking if JWFacts had it, and although they mention many older articles, it seems they didn't realize they taught there was no holy spirit.
This was a real big eye opener for me, so thought I'd share it, and curious if any of you knew about this yourselves????
I may open up my folder of custom research later and quote the articles but here is a brief description of how from Russell "anybody" could get Holy Spirit down to today where only the GB get it for understanding.
Russell correctly taught what the bible said that anybody can get holy spirit and understanding. The spirit of truth, etc. When Rutherford took over, he got very butthurt when people were questioning him, etc, and opposition that was going to come when he was going to try to make everybody become sales people for him.
So suddenly WT's released that claim that Jesus HAS returned!!!! His invisible rule!!! AND "Evidently", the holy spirit was only operating while Jesus was away. Because when Jesus was with his apostles they didn't have it, but when Jesus left, he told them he would send the teacher, the holy spirit. So since Jesus is back, there is no holy spirit anymore. Jesus has picked his faithful slave and channel to give all his people the truth and his commands. Rutherford speaking about HIMSELF in the third person, instructing how it's nobodys business HOW Jesus does it, but it's through angels or even dead brother Russell who is now serving as the annointed. But Jesus commands that there be pioneers who spend 140 hours a month doing door to door. And everybody should be selling magazines door to door. And nobody better dare question, because Jesus himself is commanding that, else it wouldn't be mentioned in the WT.
For the rest of Rutherfords life, that was the teaching. There was no holy spirit, nobody can understand the bible except through Rutherford/WT.
When Rutherford died, Knorr slowly reincorporated the holy spirit. Never an article saying the past 40 years were incorrect. Just one day it's explained that holy spirit directs the governing body and it's only through them you can get the truth. Never an explanation why only through them and no other anointed or anybody else in general. The entire basis for only the GB or president of WT having "the truth" was Rutherford saying Jesus abolished holy spirit on his return and was directly communicating through his chain of command. Later Knorr brought back holy spirit but replacing Jesus and angels for somehow holy spirit mysteriously only gets to the GB for 'new light' etc.
If nobody really knew of it like this, or there is no online way to find it, I'll make a note to list the articles and quotes in that order.
