The CDWDS instruction Redemptionis Sacramentum does contain norms to be received and followed:
[3.] The norms contained in the present Instruction are to be understood as pertaining to liturgical matters in the Roman Rite, and, mutatis mutandis, in the other Rites of the Latin Church that are duly acknowledged by law.
Also acknowledged yet again is the importance of participation. This participation is the springboard for the CDWDS and CDF’s concern about liturgical abuse:
[4.] “Certainly the liturgical reform inaugurated by the Council has greatly contributed to a more conscious, active and fruitful participation in the Holy Sacrifice of the Altar on the part of the faithful.”[Ecclesia de Eucharistia 10] Even so, “shadows are not lacking”.[Ibidem; Vicesimus quintus annus 12-13; cf. also Sacrosanctum Concilium 48] In this regard it is not possible to be silent about the abuses, even quite grave ones, against the nature of the Liturgy and the Sacraments as well as the tradition and the authority of the Church, which in our day not infrequently plague liturgical celebrations in one ecclesial environment or another. In some places the perpetration of liturgical abuses has become almost habitual, a fact which obviously cannot be allowed and must cease.
“Not infrequently” and “almost habitual” are serious charges. The culture of complaint encouraged by the curia in the later years of the John Paul II papacy almost invite a dour outlook on the state of the Church.
It is undeniable that for many Catholics, “liturgical abuse” is synonymous with “Liturgical stuff I don’t like.” RS will get specific. But for now, my sense is that liturgical abuse (conceding the term for authentic abuse) is less an issue now than it was in previous generations. Although questionable practices, like Communion from the tabernacle, have become part of the habit in many faith communities.
It is one thing to suggest abuses cannot be allowed. It is another to ensure their eradication. Is it enough to subtract? Do clergy and people need something better to put into place?
