Cardinal Mueller's book, available in Spanish and German, about the Papal Ministry (The Pope: Mission and Mandate) is currently being translated into English.
He writes more and more with the decisive frankness of our own Blessed John Henry Newman. Consider this from his recent interview:
"The primacy of the Pope is being undermined by the sycophants and careerists at the papal court."
Increasingly I wonder if this might be the man to clear up the mess which will have been left by PF. As well as every other reason, there is the fact that Mueller knows where the bodies are buried.
God bless him for all that he does for Jesus Christ.
