Then why did the Watchtower ever change anything if everything was directly from scripture? Obviously you are saying that this might not have been true last year, because some things have already changed since then, but it must be true this year. But if it's true this year, then you are claiming that any changes made for next year are no longer directly from Scripture, unless of course you are arguing that the Scriptures contradict themselves. You are using cult-speak even though the Watchtower is not a cult.
Obviously we need to question ourselves first, but to answer your first question, it's our Christian obligation to question the anointed ones. You've seen a dozen scriptures to this effect, and you evidently do not believe in them. By whose power and authority do you decide it's OK to go against the Bible, and not to question the anointed ones?
