In faith healing the guy just sits and "gets healed" by Jesus or whoever. He is there purely as the recipient of the grace that will be bestowed on him.
In Scientology, by complete contrast, the person is the agent and source of his own betterment.
I reckon that qualifies as a difference.
One would think that, but that's not quite true.
In scientology, if you grabbed a person off the street, raw meat,
the first thing a scientology auditor has to do is explain things. That right there, in that first step, is indoctrination, or getting agreement (no agreement, you're out of here, PTS/SP, open mind, etc LOL).
I believe it's called a CS-1, one has to learn the terms of ARC, e-meter, etc.
Can you grab somebody off the streets and just audit him/her?
What would the results be?
Well, the first step is to indoctrinate or educate into hubbards system, on a gradient no doubt. But isn't this an evaluation, when one indoctrinates a new person, one is telling the person what to think (hey got an F/N), but yet hubbard said auditing is not evaluation (F/N is an evaluation). But yet subtlety he did, by his subtle indoctrination or education. This is also known as persuasion or hypnosis, getting a person to think per the operators instructions.
Per the hubbard system, there is no way to audit a person to the state of clear or ot, as it is all evaluation. The whole clear or ot concept has to be introduced somewhere, and that is in itself an evaluation of what a person should think, be, do, or have, or act.
