Pope Francis recently accepted the resignation of Cardinal Robert Sarah as prefect of the Congregation for Divine Worship and Discipline of the Sacraments.
There should have been nothing particularly controversial about the news. The cardinal had already turned 75 last June, the age when all bishops are expected to submit their resignation to the pope.
It's true that Francis has allowed several cardinals who are approaching 80 years of age to keep their Roman Curia posts up till now. But that is, after all, his prerogative.
The real news concerning Cardinal Sarah — besides the fact that no one was immediately named to replace him — was actually made in 2014 when the pope appointed the ultra-conservative Guinean to head Divine Worship in the first place.
