If you are to believe what the Tower says, the Catholic church is part of Satan's organization. And so are the Protestants. So those organizations would not be Jehovah's. In fact, since about 100 AD when the original Christian congregation fizzled, there was no organization that would possibly have been Jehovah's true organization.
Even more interesting is the kind of people that the Tower claims as likely candidates for the "heavenly hope" during that period. Every single one of them was an independent thinker! Some were trying to get the Bible into the hands of the common people. The composers of the King James version, which today is the gold standard, were supposedly in that class though the Tower claims it full of errors that were put there to support false religion.
And what about the scientists? Copernicus, Galileo, and Newton are among those who the Tower claims probably had the heavenly hope. All three challenged the Establishment and are now accepted as founders of truths in science (and yet Einstein and Linus Pauling were not in the heavenly class??). All three were the type of people that, had they been in the Tower today, would likely have turned apostate and sought the real truth. As for those trying to spread the Bible to the common people, they were the Raymond Franzes of the Catholic Church (which had them burned to the stake for it).
The original Bible translators that sought to bring the Bible to the masses were in the heavenly class, yet Raymond Franz (who did effectively the same thing) is a wicked apostate that is spreading poison. What sense does that make? The only difference is that Franz did his apostasy while there was an organization, and the Bible translators did theirs when there was none. Divine justice??
