First off, I’d like to weigh in on His Eminence by saying I think it was in pour taste to air his sour grapes but hardly worth a whole thread to complain about it. There have been far more vicious things written by bishops trying to constrain and intimidate their priests in order to thwart the MP.
That said, I think the discussion about charisms and the desire not to say the NO can be seen in a more balanced contest if we get away from the TLM/NO dichotomy and look at it in the larger context of all Latin liturgies before so many orders forsook their venerable distinctive uses. A Dominican priest didn’t get ordained only to celebrate the Dominican rite, but no one ever looked askance at him for wanting to celebrate solely his own rite which, being an integral part of the spirituality of his order, was bound up with the life he chose in entering a particular community. In fact, he often needed special permission to celebrate the Roman rite, even when saying Mass in a parish (it was not until the 1940s that parishes administered by the Dominicans received permission to use the Roman rite). The same for a Norbertine, a Carmelite, a Carthusian. There need not be some sort of rejection of the Roman rite in these cases, simply a devotion to the particular spirituality embraced by one’s order. Priests belonging to todays “traditional orders” similarly have a spirituality and liturgical use proper to their order, it just so happens that the liturgical use is one of two forms of the Roman rite. Devotion to the liturgical uses of one’s order need not entail an active rejection of other uses. If a priest really did on principle refuse to celebrate a vald right under licit conditions, we would have reason to worry. But if he simply asks permission to exclusively use his community’s particular rite, I’ve got no problem.
