Snow White?
Nah, that was later. Maybe late seventies? That was a genuine fiasco. CofS tried a counter-infiltration operation of some kind and it blew up on them. They got tired of playing defense all the time and tried an offensive move. Bad idea. Playing defense sucks, but it means the government is committing all the crimes, even if none of them go to jail about it. The moment you try offensive infiltration . . . and they catch you . . . you become the criminal. There were some honchos that did prison time over that.
The DC raid was . . . let me think . . . had to be early sixties. The thing that stuck with me on that was that Kennedy was in the White House when the initial letter was written. So I would think that the raid was in 1961 or 1962, certainly no later than early 1963. I was in Europe in 1973 (ten years later), and that's when I heard about it.
I understand your objection to using the term "church" for their organization.
I, personally, would have preferred "research foundation" or maybe "scientific foundation," or something of that kind, from my own observations of their work.
Speculating here . . . (again, I only have sketchy information . . .)
Evidently, once the medical and scientific community found that Hubbard proposed a spiritual model (this would have been in the early fifties, I guess) as the foundation for his methodologies, they pretty much used their authority and influence to scupper the "foundation" approach to non-profit status. It was pointed out that "spirits" didn't belong in science, but in religion.
I'd say, in that kind of "the rest is history" way, that the decision was made to pursue that avenue.
It's been the subject of a couple of legal actions, one of which resulted in a formal acknowledgement by the IRS of their religion/church status and a confirmation of non-profit.
I've never been terribly fond of the "church" moniker. I was baptized in a church as an adult (Baptist, if you must know), and I sang in the choir, and we did the usual worship services and bible studies. There is a certain "feel" to the conventional "church" (well, Christian church, anyway) that the CofS doesn't have. Reverence? Something like that.
I guess, if I had to take a stab at the main difference between conventional churches and CofS, it would be that a conventional church is about faith and observance, whereas CofS is about understanding and application of principles and methods.
I've been told (by an outsider) that "Scientology is kind of a Westernized, technology-driven version of many of the Buddhist ideas." He wasn't trying to be flattering. I've never been a Buddhist nor have I studied Buddhism, so I couldn't speak to the accuracy of that.
So, whether I like it or not, the CofS has established its "bona fides" as a church in every country where it has branches, and the US government has "certified" them as such.
Call them a cult? I could, but I've seen their work, and I respect that. I guess I'll stick with church.
