Making it compulsory is an abuse.
Banning it completely is an abuse.
I must take issue with that last sentence in your post.
I am not asking you to take my word for it. Please refer to *Redemptionis Sacramentum *(2004) a legally binding
Instruction from the Congregation for Divine Worship and the Discipline of the Sacraments
(The bold type is my own emphasis)
[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”. 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, 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, 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. **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.
[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.
[18.] **Christ’s faithful have the right that ecclesiastical authority should fully and efficaciously regulate the Sacred Liturgy **lest it should ever seem to be “anyone’s private property, whether of the celebrant or of the community in which the mysteries are celebrated”
[30.] The office “that belongs to Priests in particular in the celebration of the Eucharist” is a great one, "for
it is their responsibility to preside at the Eucharist in persona Christi and to provide a witness to and a service of communion not only for the community directly taking part in the celebration, but also for the universal Church, which is always brought into play within the context of the Eucharist.
It must be lamented that, especially in the years following the post-Conciliar liturgical reform, as a result of a misguided sense of creativity and adaptation, there have been a number of abuses which have been a source of suffering for many".
[31.] [with regard to priests]…
They ought not to detract from the profound meaning of their own ministry by corrupting the liturgical celebration either through alteration or omission, or through arbitrary additions… Let the Church of God not be injured, then, by Priests who have so solemnly dedicated themselves to the ministry. Indeed, under the Bishop’s authority
let them faithfully seek to prevent others as well from committing this type of distortion.
Extra emphasis was added by me in #31. My own words follow:
You see, my friend, a priest has a solemn obligation NOT to permit unauthorized changes to the Mass. The faithful have a RIGHT to clerics who faithfully follow the liturgical norms of the Church.
These are not merely my words, these is not merely my opinion, this is not merely my interpretation of vague instructions open to many interpretations. This is the teaching and liturgical law of the Church. Read it for yourself. Don’t take my word. Don’t take the word of anyone else posting here. Read it for yourself.
