A few excerpts from the 2004 Instruction
Redemptionis Sacramentum:
"[11.] The Mystery of the Eucharist “is too great for anyone to permit himself to treat it according to his own whim, so that its sacredness and its universal ordering would be obscured”.[27] On the contrary, anyone who acts thus by giving free reign to his own inclinations, even if he is a Priest, injures the substantial unity of the Roman Rite, which ought to be vigorously preserved,[28] and becomes responsible for actions that are in no way consistent with the hunger and thirst for the living God that is experienced by the people today. "
“[13.] All of the norms and exhortations set forth in this Instruction are connected, albeit in various ways, with the mission of the Church, whose task it is to be vigilant concerning the correct and worthy celebration of so great a mystery.”
"
6. Complaints Regarding Abuses in Liturgical Matters
[183.] In an altogether particular manner, let everyone do all that is in their power to ensure that the Most Holy Sacrament of the Eucharist will be protected from any and every irreverence or distortion and that all abuses be thoroughly corrected. This is a most serious duty incumbent upon each and every one, and all are bound to carry it out without any favouritism.
[184.] Any Catholic, whether Priest or Deacon or lay member of Christ’s faithful, has the right to lodge a complaint regarding a liturgical abuse to the diocesan Bishop or the competent Ordinary equivalent to him in law, or to the Apostolic See on account of the primacy of the Roman Pontiff.[290] It is fitting, however, insofar as possible, that the report or complaint be submitted first to the diocesan Bishop. This is naturally to be done in truth and charity."
From 186: "Let Bishops, Priests and Deacons, in the exercise of the sacred ministry, examine their consciences as regards the authenticity and fidelity of the actions they have performed in the name of Christ and the Church in the celebration of the Sacred Liturgy. Let each one of the sacred ministers ask himself, even with severity, whether he has respected the rights of the lay members of Christ’s faithful, who confidently entrust themselves and their children to him, relying on him to fulfill for the faithful those sacred functions that the Church intends to carry out in celebrating the sacred Liturgy at Christ’s command.[294] For each one should always remember that he is a servant of the Sacred Liturgy.[295]
All things to the contrary notwithstanding.
This Instruction, prepared by the Congregation for Divine Worship and the Discipline of the Sacraments by mandate of the Supreme Pontiff John Paul II in collaboration with the Congregation for the Doctrine of the Faith, was approved by the same Pontiff on the Solemnity of St. Joseph, 19 March 2004, and he ordered it to be published and to be observed immediately by all concerned."
