  This sort of says it all. Being the official voice of the Pope, while recognizing the Pope as the #1 teacher in the Church, would be an impossible job if he disagreed with the Pope. He did not disagree with the Pope or Schönborn, since he was part of the German language group at the Synod that unanimously proposed the solution to the divorce question that was accepted by the Synod. 
  
  I have expected Müller's term would end on this day for the last few years, ever since Francis confirmed his 5 year term in 2013.
