Nevertheless, from the fact that the liturgical celebration obviously entails activity, it does not follow that everyone must necessarily have something concrete to do beyond the actions and gestures, as if a certain specific liturgical ministry must necessarily be given to the individuals to be carried out by them. Instead, catechetical instruction should strive diligently to correct those widespread superficial notions and practices often seen in recent years in this regard, and ever to instill anew in all of Christ’s faithful that sense of deep wonder before the greatness of the mystery of faith that is the Eucharist, in whose celebration the Church is forever passing from what is obsolete into newness of life: "in novitatem a vetustate".[101] For in the celebration of the Eucharist, as in the whole Christian life which draws its power from it and leads toward it, the Church, after the manner of Saint Thomas the Apostle, prostrates herself in adoration before the Lord who was crucified, suffered and died, was buried and arose, and perpetually exclaims to him who is clothed in the fullness of his divine splendour: "My Lord and my God!"[102]

The reprobated practice by which Priests, Deacons or the faithful here and there alter or vary at will the texts of the Sacred Liturgy that they are charged to pronounce, must cease. For in doing thus, they render the celebration of the Sacred Liturgy unstable, and not infrequently distort the authentic meaning of the Liturgy.

In selecting the biblical readings for proclamation in the celebration of Mass, the norms found in the liturgical books are to be followed,[136] so that indeed "a richer table of the word of God will be prepared for the faithful, and the biblical treasures opened up for them".[137]
#62
It is also illicit to omit or to substitute the prescribed biblical readings on one's own initiative, and especially "to substitute other, non-biblical texts for the readings and responsorial Psalm, which contain the word of God".[138]
