Perhaps Raymond Cardinal Burke, could be be offered the opportunity to enter into the same spiritual retreat from the concerns of the world as his equally esteemed colleague, Keith Cardinal O'Brien.  Sharing a small house together would create enormous domestic economies that the whole Church could applaud.  Not to mention the spiritual benefit they might enjoy in such fraternal company: Every morning they could serve each other as Acolyte for their daily Mass ; they could hear each-others confessions ; they could read the Catechism of the Catholic Church together antiphonally over lunch, or some other spiritual reading approved for retired clerics.   Their selfless obedience to silence would, of course, edify all of Christendom.
