If the lex orandi (law of prayer) is the lex credendi (law of belief), as the venerable old adage goes, then we should not be surprised that just beneath the surface of this liturgical decree lays the real concern of Francis’s striking intervention: the legacy of the Second Vatican Council and the contested lex credendi of the Catholic Church. Much more than a decree regulating liturgy, Traditionis Custodes is a decisive moment in the history of papal reception of Vatican II.
