Excellent point Lisabobeesa!
I thought the same thing. They never really believed in an FDS class from 33 CE onward themselves! If they did, then they would know who these persons are, and would have gladly sought out their advice, just like the supposed " Governing Body " of the Christian era! Since the slave " class " was a bunch of filler and bullarky to begin with, the GB were waiting for the chance to refine this " truth." What better time to do some refining than the age of rising numbers of the conscious class/partakers?
The GB predicted that the diminishing number of partakers was a sure sign that the end was close! Uh-oh!!! Now what?! The GB=the FDS, of course! Throw in some hate speech about partakers being mental. If that doesn't work just come out and say it, " Partaking is forbidden!" In other words, " WE ARE THE BOSS OF YOU!"
Of course had any of us said there was no FDS class 2 years ago ( Heck, 2 months before the nu-light last year) , we would have been harboring private beliefs and could not have been in good standing among Jehovah's people. If we had insisted on teaching this " nu-light " before it's time then we could have been removed as apostates for spreading gangrenous talk, just like Korah.
