Catechesis. The Documents of the Second Vatican Council. III. Constitution Sacrosanctum Concilium. 8. The motivations of the liturgical reform

Dear brothers and sisters,

In this final catechesis on the Constitution Sacrosanctum Concilium, today I would like to look at the reasons why the Council Fathers sought to promote a reform of the liturgy. In this regard, the third Letter from the Council, which Cardinal Giovanni Battista Montini, then Archbishop of Milan, sent on 28 October 1962 to the faithful of his Church, is particularly enlightening. The liturgy, he wrote, “is a sincere expression of both the divine and the human. It is language. On the one hand, it is a vehicle for divine teaching; on the other, it is a voice in dialogue with God. It is clear that it cannot renounce its didactic function, nor can it fail to offer faith and piety the opportunity to be expressed with spontaneous intelligibility”. (G. B. Montini, «Third Letter from the Council», Rivista Diocesana Milanese 51 (1962) 921-923: 922.) Motivated by these convictions, the future Pope Saint Paul VI affirmed that the faithful “cannot and must no longer remain silent and passive. Their physical presence cannot be reconciled with their spiritual absence”. (Ibid.)

The similarity between these statements and those which would appear in no. 48 of the Conciliar Constitution is evident: “The Church … earnestly desires that Christ’s faithful, when present at this mystery of faith, should not be there as strangers or silent spectators; on the contrary, through a good understanding of the rites and prayers they should take part in the sacred action conscious of what they are doing, with devotion and full collaboration. They should be instructed by God’s word and be nourished at the table of the Lord’s body; they should give thanks to God; by offering the Immaculate Victim, not only through the hands of the priest, but also with him, they should learn also to offer themselves; through Christ the Mediator they should be drawn day by day into ever more perfect union with God and with each other, so that finally God may be all in all”. These words express a renewed awareness of the value of the liturgy. Through the Church’s ritual actions, while the memorial of the work of salvation is celebrated, the opportunity is provided to experience a true relationship with God, coming into contact with the salvific event. Since the gestures and the words of the sacred liturgy are critical to realizing this experience, the participation of the faithful cannot be passive.

By placing what constitutes the heart of the ecclesial experience at the centre, the Conciliar reform was intended to allow the liturgy to shine forth as “the primary source of that divine exchange in which the life of God is communicated to us” (Solemn Closing of the Second Session of the Council, Allocution of the Holy Father Paul VI (4 December 1963)). From this conviction, the need arose to make the richness of biblical texts and prayers more accessible to all the faithful, and to streamline the order of the celebration compared with what had been set out in the liturgical books in use at the time.

Indeed, since the liturgy is a living entity, it has always been subjected to developments and changes throughout the centuries. The Magisterium adapted its forms to the needs of different eras. It is therefore not surprising that the Second Vatican Council too, with the utmost respect for the heritage of tradition, and precisely in order to make it more accessible, considered it necessary to revise the liturgical books.

The aim that the Fathers had in mind is explained in no. 21 of the Constitution Sacrosanctum Concilium: “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. In this restoration, both texts and rites should be drawn up so that they express more clearly the holy things which they signify; the Christian people, so far as possible, should be enabled to understand them with ease and to take part in them fully, actively, and as befits a community”. The distinction, within the liturgy, between divine, immutable elements, and human elements, which instead “admit of various modifications, as the needs of the age, circumstance and the good of souls may require, and as the ecclesiastical hierarchy, under guidance of the Holy Spirit, may have authorized”, dates back to Pope Pius XII’s Encyclical Mediator Dei  (Acta Apostolicae Sedis 39, 1947, 541–542).

Moreover, the desire for a “general reform” did not come about suddenly, but had been evident in the actions of successive Popes since the beginning of the 20th century, in keeping with the demands of the Liturgical Movement. The assertion that the faithful should not attend celebrations “as strangers or silent spectators” had already been raised in Pope Pius XI’s Apostolic Constitution Divini Cultus . Furthermore, one may recall Pope Pius XII’s interventions regarding the ordering of the rites of Holy Week, which he rescheduled to the hours corresponding to the events of Easter, after they had for centuries been brought forward to the morning hours. Nor should it be forgotten that Saint John XXIII regarded it necessary to simplify the rubrics of the Breviary and the Missal, approving this with the Motu proprio Rubricarum instructum  of 25 July 1960, in which he referred the proposal of fundamental principles for a reform of the liturgy at the forthcoming Ecumenical Council.

The liturgical reform promoted by the Second Vatican Council is thus firmly rooted in the living tradition of the Church. A correct understanding of it also enables us to reject the abuses that occurred in certain sectors of the Church during the post-Conciliar period, and which, unfortunately, still occur from time to time today, where some of the principles underlying the reform itself have been taken to extremes or misunderstood.

In this regard, it is worth recalling that the Conciliar Constitution affirms that “Liturgical services are not private functions, but are celebrations of the Church, which is the ‘sacrament of unity’, namely, the holy people united and ordered under their bishops. Therefore liturgical services pertain to the whole body of the Church; they manifest it and have effects upon it” (Sacrosanctum Concilium, no. 26).

It is therefore the primary responsibility of pastors, of bishops, but also of each individual priest, to safeguard and promote a liturgy which, while respecting liturgical norms, shines with noble simplicity (cf. no. 34) and thus manifests the one, holy, catholic and apostolic Church. Such a liturgy will also be a fundamental vehicle for evangelization, the instrument of grace through which, as the Council teaches, we may learn to offer ourselves and, through Christ’s mediation, be perfected in unity with God and amongst ourselves (cf. no. 48).

I greet all the English-speaking pilgrims and visitors taking part in today’s Audience, particularly the groups from Malta, Senegal and Canada. A special greeting to those serving in the National Offices of the Pontifical Mission Societies. Upon you and your families, I invoke the joy and peace of our Lord Jesus Christ. God bless you all!

Il mio pensiero va, infine, ai giovani, ai malati e agli sposi novelli. Domani e dopo domani la liturgia fa memoria di due grandi Santi, santa Monica e sant’Agostino, uniti in terra da vincoli familiari e in cielo dallo stesso destino di gloria. Il loro esempio susciti in ciascuno una ricerca sincera e appassionata della Verità evangelica, per testimoniarla con gioia nella vita di ogni giorno. A tutti la mia benedizione!

Dear brothers and sisters, in this final catechesis on the Second Vatican Council’s Constitution on the Sacred Liturgy, Sacrosanctum Concilium, we recall the reasons the Council Fathers promoted a liturgical reform. When the Church carries out a reform of the liturgy — a constant process of development across the centuries — there is an important distinction to be made between the divine, immutable elements, and the human elements, which may undergo various modifications. The need arose for the faithful to celebrate the liturgies more consciously and actively, not “as strangers and silent spectators,” but participating fully in the salvific mystery. In this way, the Christian people learn to recognize sacred realities, offer themselves with and through the hands of the priest, and become more open to receiving God’s grace. At every celebration of the Sacraments, especially the Eucharist, let us ask for God’s help to be strengthened on our journey and to enter into a deeper relationship with the Lord.
