At the WT study, JWs will marvel at how humble the GB is to admit that they are neither inspired nor infallible.
Then they will resolve to double down on obeying them without question and to wait on Jehovah to make any corrections that may be needed.
Interesting though.
How will Jehovah make corrections given that He is not directing the GB?
How can anyone obey without question when what you are obeying may be wrong?
Imagine a child needing a blood transfusion now to save their lives and the parents have just read that WT study article that the GB may get doctrines wrong. How can they obey them by refusing a blood transfusion when the GB MAY be wrong about their interpretation of the meaning of that scripture about blood?
You may have future JC's where the person involved can say "well the GB may have it wrong, look it says here that they can err in doctrines".
A dub can turn round and say to an elder "Is it wise to obediently follow 100% what the GB says when they themselves admit they can be wrong in matters?"
What is now the difference between say Catholics (a man in charge, no direct inspiration from God and can get doctrines wrong and change them) and the GB (group of men in charge, no direct inspiration from God and can get doctrines wrong and change them)?
This is why I say this WT opens up a can of worms in my opinion. To say, in print, the GB can get it wrong means if anyone follows it blindly and obediently then it is just the same as other religions in that they are following men.
And to follow it blindly just adds to the fact it is indeed a cult.
