If that principle held true, then nobody would be able to call themselves "reformed church" of anything, yet it happens all the time.
But Fluffy, there has NEVER been another "religion" or "movement" that took some much time, effort and energy to MAKE SURE that it NEVER CHANGED (i.e. "reformed" being one possible version of change)!!!!!!
Scientology IS very unique in that regard when compared to other movements and social activities.
Hubbard took incredible effort to write ENDLESS policies that set out HOW it MUST be run, down to his
anal-retentive exquisite detail of certain endless requirements (various EPs, "products", etc), and also to ensure the subject would NEVER CHANGE through an exactly set-up Qual, ethics, and everything else to monitor, detect, catch and CORRECT ANY DEVIATION from the subject. This sort of planning and behavior is NOT common in just about ANY "modern" religion. I am not saying that the Catholic Church doesn't "plan", it surely does, but the DEGREE to which Hubbard took "executing programs" and "getting things done just as intended", well, Scientology stands alone in this regard.
You don't find things like:
"Keeping Islam Working"
or
"Hard Sell" by the minister at the local Christian Church soliciting donations, after he has just spent 3 hours doing TRs (to not betray his real feelings), TR lying, various "dissem drills", and other assorted "drilled practices" designed to MAXIMIZE the effectiveness of the indoctrination & selling tools. Oh, you find it in companies and MLM groups, but NOT most religions.
Fluffernutter, in words not much unlike Hubbard's own, and he was RIGHT in this regard, humans seem to love to and generally will ALTER everything one touches. It might not even be a "human" factor alone, but ANYTHING existing in this universe eventually morphs into something else - given enough time. But also, people are notorious for "getting it wrong" - poor duplication or tendency to alter by way of "fixed ideas" and preconceived notions in ones thinking.
So, yes, many other "isms" and "ologies" suffer from, or go through an endless changing into something else. Hubbard was unique in this, and maybe entirely alone, in that he clearly recognized this tendency for human created things to change (a correct observation as I see it), and he took amazing far-past-the-usual efforts to prevent it from happening to HIS subject. That the thing he was trying to stop from morphing into something else, the subject of Scientology itself, was grossly flawed, is another topic entirely.
Saying it "happens all of the time", while using other past religions as examples of "reformation", is NOT a valid comparison, because ONLY Hubbard and Scientology, within the large expanse of ALL religions, involve EXTENSIVE carefully laid-out intentions, plans, programs and policies, right down to amazing detail, with exact patter, exact responses, and so forth, specifically designed to realize the clearly stated INTENTION of "a subject left forever unchanged" by the "reactive" impulses of humans with avid cravings to be liked. A policy or essay like "KSW" is NOT common in other "isms" or "ologies".
On an IQ test:
Scientology is to KSW
as
The Catholic Church is to ( blank).
It's a trick question. None of the other religions have anything even closely resembling such an intention, plan, design, or aim.
Flunk!
But, you know I love you anyway.
