I am thinking about the problems with the translation of SacrCar 23. They are serious. As you know, the translation distorted the Latin and/or Italian focus on the priest leading the liturgical "action" toward the priest leading the "assembly". That is wrong in so many way, one hardly knows where to begin.
However, a friend reminded me of Card. Arinze’s marvelous speech in London on 3 April 2006 which I want to call to your minds. This is a very good lens, or hermeneutic, with which to read SacrCar 23.
Try this on for size (my emphasis).
"Liturgy", says Pope John Paul II, "is never anyone’s private property, be it of the celebrant or of the community in which the mysteries are celebrated. Priests who faithfully celebrate Mass according to the liturgical norms, and communities which conform to those norms, quietly but eloquently demonstrate their love for the Church" (Eccl. de Euch., 52). At the direction of Pope John Paul II, the Congregation for Divine Worship and the Discipline of the Sacraments, in collaboration with the Congregation for the Doctrine of the Faith, issued the Instruction Redemptionis Sacramentum in March 2004 "precisely to bring out more clearly this deeper meaning of liturgical norms" (Eccl. de Euch., 52).
It follows that individuals, whether they be priests or lay faithful, are not free to add or subtract any details in the approved rites of the celebration of the Holy Eucharist (cf Sacrosanctum Concilium, 22). A do-it-yourself mentality, an attitude of nobody-will-tell-me-what-to-do, or a defiant sting of if-you-do-not-like-my-Mass-you-can-go-to-another-parish, is not only against sound theology and ecclesiology, but also offends against common sense. Unfortunately, sometimes common sense is not very common, when we see a priest ignoring liturgical rules and installing creativity in his case personal idiosyncracy as the guide to the celebration of Holy Mass. Our faith guides us and our love of Jesus and of his Church safeguards us from taking such unwholesome liberties. Aware that we are only ministers, not masters of the mysteries of Christ (cf I Cor 4:1), we follow the approved liturgical books so that the people of God are respected and their faith nourished, and so that God is honoured and the Church is gradually being built up.
Notice the how Card. Arinze made the connection between obedience to the RITE with both respect for the people and building up the Church.
