Thank you. I’ll need to research the way in which schism is being discussed.
Meanwhile, I am very grateful for *your* summary. I had no idea Muller had been in a position to override the Pope on doctrinal matters. That was an extremely helpful insight. To think Muller (apparently) tried to play it safe, only to be shunted aside. That is food for thought.
He may have been doing that in the hopes of keeping his job longer so that Francis wouldn't replace him with someone who's heterodox sooner. So, it may have been with good intentions, but it's had bad results.
