The Catholic Church is huge, and contrary to popular paranoia and myth, the hierarchy isn’t as unified nor does it micromanage the affairs of all of its members.
The rules are more or less enforced on the honor system, particularly with the rank and file.
But if there's ever a case to be made for "micromanaging" it's with someone like Nan...or Teddy K....or John F'ing Kerry.Their Bishop could publicly announce "recant,repent and change your attitude or don't even bother coming to the Communion rail in my Diocese...or in any other".
