Actually even if you coalate folks purely on congruent beleifs (rather than congruent beleifs divided amoung different administrations that may or may not be in communion with eachother) there are still thousands of denominations, and I’d wager far more than 30,000 actually.
and that number would HAVE to include also RC’s and orthos. But I realize that you won’t see that, and I know I won’t convince you, so I don’t really see a need to continue. Besides, I have stuff I have to get acomplished today.
