I'm not sure this is true under Canon Law. The Bishop controls the faculties of priests in his diocese, and he can grant and suspend priestly faculties at will. The same goes for an Abbot.
As Cardinal, Burke is not necessarily this Abbot-Povost's ecclesiatical superior, on the Abbot's own territory.
Nevertheless, what this Abbot did was obnoxiously insulting. Burke has been singled out for public humiliation. THis --- and his equanimity, his refusal to lash out --- makes me think God is choosing him to be a great saint.
I still think Burke could be the next Pope.
Oremus.
My copy of Canon Law is at work, and I wouldn’t count on my memory for details, but things do work differently for Bishops, and it wouldn’t surprise me if they were even more different for Cardinals.
Any cardinal possesses faculties to celebrate the sacraments anywhere on earth, and presumably beyond. What Cardinal Burke does not possess is the right to celebrate at a place where he’s unwelcome. He was refused a venue, perhaps because pressure was applied to deny him access; so far as I can tell this has nothing to do with faculties.
St. John Paul the Great referenced Cardinal Burke as "My Little Raimundo" and sped his course up the hierarchichal ladder. God can facilitate his final earthly ascent. The progressives will be in complete panic over such an election.
Certainly, as pope, Burke would be the religious superior of all concerned and might well wish to invite the abbot ans Christoph Cardinal Schonbrun for a little conversation about manners and clerical ethics at the newly restored papal palace residence of Burke as Pius XIII or whatever, The discussion might take place right after the guests attend Papa Burke's daily Tridentine Mass at St. Peter's and just before that day's announcement of the retirement to cloister of Schonbrun and the abbot.
From your lips to God's ears.
