I thought the previous WT teaching was that the anointed remnant was the faithful and discreet slave class and that they were always somehow faithfully proclaiming Jehovah's truth on earth throughout the centuries.
You are correct.
Given the WT views, how could anyone from 33 CE to 1919 CE understand Bible truth without "God's organization" to explain it to them?
That would be the $144,000 question, now, wouldn't it? The WT has no idea who these people were.
p. 10, par. 4: "Speaking about the wheat and the weeds, Jesus said: "Let both grow together until the harvest." This command reveals that from the first century until today, there have always been some anointed wheatlike Christians on earth...So anointed Christians would be protected by Jesus all the days leading up to the time of the end. However, since they were overgrown by weedlike Christians, we do not know for certain who belonged to the wheat class during that long period of time."
So while they will go so far as to say there have always been anointed Christians around in all those years, they provide no explanation as to how such individuals came to understand 'Bible truth'. If I had to offer a JW-based guess, I would say the answer would be that those anointed ones received spirit-directed guidance to grasp some small portion of Bible truth that was evidently hidden from the majority of Christendom, the weedlike Christians during that long period. Like say, one person or small group understood that the Trinity was wrong. Or that hellfire was wrong. Or [insert JW teaching here].
But the bottom line is that that's just guesswork. The Society apparently doesn't think that issue is particularly relevant; there may not have been an organization then, but there is one now, and you would do well to provide your loyal cooperation and leave matters in Jehovah's hands regarding this question. And for asking the question, you're officially marked.
