Redemptionis Sacramentum 2004 - Part 3

[10.]  The Church herself has no power over those things which were established by Christ Himself and which constitute an unchangeable part of the Liturgy.23 Indeed, if the bond were to be broken which the Sacraments have with Christ Himself who instituted them, and with the events of the Church's founding,24 it would not be beneficial to the faithful but rather would do them grave harm. For the Sacred Liturgy is quite intimately connected with principles of doctrine,25 so that the use of unapproved texts and rites necessarily leads either to the attenuation or to the disappearance of that necessary link between the lex orandi and the lex credendi.26

[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 rein 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. Nor do such actions serve authentic pastoral care or proper liturgical renewal; instead, they deprive Christ's faithful of their patrimony and their heritage. For arbitrary actions are not conducive to true renewal,29 but are detrimental to the right of Christ's faithful to a liturgical celebration that is an expression of the Church's life in accordance with her tradition and discipline. In the end, they introduce elements of distortion and disharmony into the very celebration of the Eucharist, which is oriented in its own lofty way and by its very nature to signifying and wondrously bringing about the communion of divine life and the unity of the People of God.30 The result is uncertainty in matters of doctrine, perplexity and scandal on the part of the People of God, and, almost as a necessary consequence, vigorous opposition, all of which greatly confuse and sadden many of Christ's faithful in this age of ours when Christian life is often particularly difficult on account of the inroads of "secularization" as well.31

[12.] On the contrary, it is the right of all of Christ's faithful that the Liturgy, and in particular the celebration of Holy Mass, should truly be as the Church wishes, according to her stipulations as prescribed in the liturgical books and in the other laws and norms. Likewise, the Catholic people have the right that the Sacrifice of the Holy Mass should be celebrated for them in an integral manner, according to the entire doctrine of the Church's Magisterium. Finally, it is the Catholic community's right that the celebration of the Most Holy Eucharist should be carried out for it in such a manner that it truly stands out as a sacrament of unity, to the exclusion of all blemishes and actions that might engender divisions and factions in the Church.32

[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. The last chapter of the present Instruction will treat of the varying degrees to which the individual norms are bound up with the supreme norm of all ecclesiastical law, namely concern for the salvation of souls.33
