punkofnice: The term CULT springs to mind.
That's what it is. Question everything, except what we tell you.
The WTS stance, for a very long time, has been to give the impression that you can test what they say with the Scriptures to see if they are being truthful. But what they are specifically saying is that, if you test what they say with the Scriptures, you will see that they are being truthful. It's not a subtle difference! The latter is making clear that if you disagree with them, you are going against the will of Jehovah and are at risk of eternal death.
And it is not a matter of whether they got it right or wrong, but whether you followed them. If you test them and find that they got it wrong and you got it right, Jehovah is upset at you for getting too far ahead of his 'light.'
