Vatican II & Liturgy - Part 3
“[T]he liturgy is the summit toward which the activity of the Church is directed; at the same time it is the font from which all her power flows. For the aim and object of apostolic works is that all who are made sons of God by faith and baptism should come together to praise God in the midst of His Church, to take part in the sacrifice, and to eat the Lord's supper.
The liturgy in its turn moves the faithful, filled with ‘the paschal sacraments,’ to be ‘one in holiness’ (Postcommunion for both Masses of Easter Sunday); it prays that ‘they may hold fast in their lives to what they have grasped by their faith’ (Collect of the Mass for Tuesday of Easter Week); the renewal in the Eucharist of the covenant between the Lord and man draws the faithful into the compelling love of Christ and sets them on fire. From the liturgy, therefore, and especially from the Eucharist, as from a font, grace is poured forth upon us; and the sanctification of men in Christ and the glorification of God, to which all other activities of the Church are directed as toward their end, is achieved in the most efficacious possible way.
“But in order that the liturgy may be able to produce its full effects, it is necessary that the faithful come to it with proper dispositions, that their minds should be attuned to their voices, and that they should cooperate with divine grace lest they receive it in vain (Cf. 2 Cor. 6:1). Pastors of souls must therefore realize that, when the liturgy is celebrated, something more is required than the mere observation of the laws governing valid and licit celebration; it is their duty also to ensure that the faithful take part fully aware of what they are doing, actively engaged in the rite, and enriched by its effects.
“Mother Church earnestly desires that all the faithful should be led to that fully conscious, and active participation in liturgical celebrations which is demanded by the very nature of the liturgy. Such participation by the Christian people as ‘a chosen race, a royal priesthood, a holy nation,’ a redeemed people (1 Pet. 2:9; cf. 2:4-5), is their right and duty by reason of their baptism.
“In the restoration and promotion of the sacred liturgy, this full and active participation by all the people is the aim to be considered before all else; for it is the primary and indispensable source from which the faithful are to derive the true Christian spirit; and therefore pastors of souls must zealously strive to achieve it, by means of the necessary instruction, in all their pastoral work.
“Yet it would be futile to entertain any hopes of realizing this unless the pastors themselves, in the first place, become thoroughly imbued with the spirit and power of the liturgy, and undertake to give instruction about it” (Second Vatican Council, Sacrosanctum Concilium, para. 10-11, 14).
