There seem to be a lot of bits in the media from Important People, even sometimes the Great and the Good, about how Benedict sinned and behaved "uncollegially" by issuing Anglicanorum coetibus without lengthy consultations with mainstream Anglican bishops and their liberal chums among the RC bishops and Uncle Tom Cobbly and All.
Personally, I regard it as one of the prime functions of the Successor of S Peter to reach out and protect small, orthodox, and persecuted minorities against all manner of heterodox local bully-boys and play-ground tyrants/tyrantesses.
I'm not quite sure where that is spelt out in Magisterial documents. "It isn't", you say? Well then, that is an important item for the agenda of Vatican III. What we need is a stronger and more interventionist Papacy.
