If Francis does nothing to make such structural and juridical changes, it is not inconceivable that when the overwhelmingly conservative College of Cardinals elects his successor -- and most likely in the not too distant future -- the new pope would reverse the movement for reform that's currently underway.
And if it were a Pope Cyprian I or Pius XIII (also known as Cardinal Robert Sarah), the reversal would be swift and uncompromising. Of course, they'd have to tear down the walls of our churches to prevent people from crushing each other in the mass exodus that might cause.
