My entry into the 'you might be x if you y' genre... enjoy.

Your church might be post-traditional if:
  • A denomination is seeking to assimilate you or reel you back in
  • A denomination is trying to take credit for what you are doing
  • A denomination is preaching against what you are doing
btw, denominations are defenders of a particular tradition, so you would expect them to see a post-traditional group as a threat to their well-being.
