Most religions get altered in some way by someone. In Scientology, we have a word for this. It's called "squirrelling".
The Scientology definition of "squirrelling" is: "Squirrelling (going off into weird practices or altering Scientology) only comes about from noncomprehension."
It's interesting to look at, because you see this happening with other religions a lot. People interpret what others have said differently, the religions branch out and end up saying something very different from what the original said. It makes sense that this would all stem from someone not understanding why something is that way, then changing it.
