I'm not taking a shot at newton, except to say he had some very non-traditional ideas, and some interesting obsessions. Most of which are blessedly forgotten.
His science lives on. I rather doubt that his theology will ever be more than a curiosity, even though I lean toward Deism.
He sure did, js1138. But I'll tell you this: If Newton (or Galileo for that matter) was a "heretic," then there's an excellent chance that I am one, too. :^)
