Pope Francis urges Catholics to value the liturgical reform borne out of Sacrosanctum Concilium, Vatican II’s Constitution on the Sacred Liturgy. He calls for a “serious and dynamic liturgical formation” for all. Without a proper understanding, the celebration can easily fall “into a preoccupation with the exterior (more or less refined) or into a concern only for rubrics (more or less rigid).”
Pope Francis adds: “With this letter I simply want to invite the whole Church to rediscover, to safeguard, and to live the truth and power of the Christian celebration. I want the beauty of the Christian celebration and its necessary consequences for the life of the Church not to be spoiled by a superficial and foreshortened understanding of its value or, worse yet, by its being exploited in service of some ideological vision, no matter what the hue.”
