Vatican II & Liturgy - Part 4
“In order that the Christian people may more certainly derive an abundance of graces from the sacred liturgy, holy Mother Church desires to undertake with great care a general restoration of the liturgy itself. For the liturgy is made up of immutable elements divinely instituted, and of elements subject to change. These not only may but ought to be changed with the passage of time if they have suffered from the intrusion of anything out of harmony with the inner nature of the liturgy or have become unsuited to it.
“[T]he sacred Council establishes the following general norms:
1. Regulation of the sacred liturgy depends solely on the authority of the Church, that is, on the Apostolic See and, as laws may determine, on the bishop.
2. In virtue of power conceded by the law, the regulation of the liturgy within certain defined limits belongs also to various kinds of competent territorial bodies of bishops legitimately established.
3. Therefore no other person, even if he be a priest, may add, remove, or change anything in the liturgy on his own authority.
“That sound tradition may be retained, and yet the way remain open to legitimate progress careful investigation is always to be made into each part of the liturgy which is to be revised. This investigation should be theological, historical, and pastoral. Also the general laws governing the structure and meaning of the liturgy must be studied in conjunction with the experience derived from recent liturgical reforms and from the indults conceded to various places. Finally, there must be no innovations unless the good of the Church genuinely and certainly requires them; and care must be taken that any new forms adopted should in some way grow organically from forms already existing” (Second Vatican Council, Sacrosanctum Concilium, para. 21-23).
In our endeavors to give God the greatest glory in the Mass, let us be guided by the instructions the Church gives us in how we celebrate the august sacrifice. The Council was clear when it forbids even a priest to add, remove, or change anything when he presides at liturgical celebrations.
