You will sometimes see Scientology described as “non-denominational” This is not accurate. The correct term is “all-denominational.”
Here are a few quotes from L. Ron Hubbard on the subject:
“We are all denominational rather than non-denominational, and so we should be perfectly willing to include in our ranks a Moslem or a Taoist, as well as any Protestant or Catholic…”
From the book "Scientology: The Fundamentals of Thought":
“The eighth dynamic is the urge toward existence as infinity. This is also identified as the Supreme Being. This is called the eighth dynamic because the symbol of infinity stood upright makes the numeral “8.” This can be called the infinity or God dynamic…. "
“These dynamics could best be represented as a series of concentric circles wherein the first dynamic would be the center and each new dynamic would be successively a circle outside it.
“The basic characteristic of the individual includes his ability to so expand into the other dynamics, but when the seventh dynamic is reached in its entirety one will only then discover the true eighth dynamic.” (emphasis added)
Scientology is a path to personal spiritual enlightenment and knowledge. Or, as Hubbard phrased it in a discussion with a student on the nature of God in a lecture of 12 February 1957 entitled "Final Lecture: Questions and Answers" (Released as part of the "Anatomy of Cause" lectures):
“Don’t ever miss this in what I teach you don’t ever miss this: I am telling you how to get there, not what is there….We are studying a way of traveling rather than a series of destinations….”
“Now, there is an eighth dynamic which so far exceeds the ability of man to describe, and so calls into paucity his language, that for a couple of thousand or twenty-five hundred years, he has been totally confused and inarticulate on the subject. And never at any time would I put my foot in that morass, unless I wanted to go morass swimming.”
