the pharmer,
C.T. Russell stated that if someone were to read the Bible without the benefit of his writings to "help" them understand, they would be completely in darkness within 6 months. As far as I know, this belief hs not changed among the the powers that be at the WTS, be it Rutherford, Knorr, Franz or the subsequent Governing Bodies.
I think the question you asked would be easy for a JW to answer...you would be wrong and the WTS would be right if there was a conflict in understanding. If your understanding was the same, the WTS would still be correct...and you just happen to agree with it. A JW would also probably say if you did agree that it was because of the understanding you were given by the WTS!
