Have you worked out a meaning yet? lain:
Yes. Some years ago here on TOL. You used to be able to "google" it but not any more. It has not survived TOL's many remakes. I do remember a few of it's tenets.
I do remember that Nonismatists believed that the answer to Cain's question was, "yes".
They reject any and all "isms" while reserving the right to embrace the portions of any that they find useful. This, of course, also requires some sense of irony and humor... being that Nonismatism is yet another "ism".
They also believe that one's understanding of the word of God is an ongoing process and the fact that any two adherent's understanding of said word might differ at any particular point in time was not necessarily a hanging offense. Suffice to say that notion was not readily embraced by all that frequent this establishment.
I do seem to remember an admonition to maintain the purity of Nonismatic thought and not drift into Ultranonismatism or Antinonismatism.
It's been a while. Perhaps other points of Nonismatic faith will surface with further cogitation.
