2. Certain Forms of Worship of the Most Holy Eucharist Outside Mass
[134.] “The worship of the Eucharist outside the Sacrifice of the Mass is a tribute of inestimable value in the life of the Church. Such worship is closely linked to the celebration of the Eucharistic Sacrifice.” Therefore both public and private devotion to the Most Holy Eucharist even outside Mass should be vigorously promoted, for by means of it the faithful give adoration to Christ, truly and really present, the “High Priest of the good things to come” and Redeemer of the whole world. “It is the responsibility of sacred Pastors, even by the witness of their life, to support the practice of Eucharistic worship and especially exposition of the Most Holy Sacrament, as well as prayer of adoration before Christ present under the eucharistic species.”
[135.] The faithful “should not omit making visits during the day to the Most Holy Sacrament, as a proof of gratitude, a pledge of love, and a debt of the adoration due to Christ the Lord who is present in it.” For the contemplation of Jesus present in the Most Holy Sacrament, as a communion of desire, powerfully joins the faithful to Christ, as is splendidly evident in the example of so many Saints. ‘Unless there is a grave reason to the contrary, a church in which the Most Holy Eucharist is reserved should be open to the faithful for at least some hours each day, so that they can spend time in prayer before the Most Holy Sacrament.”
[136.] The Ordinary should diligently foster Eucharistic adoration, whether brief or prolonged or almost continuous, with the participation of the people. For in recent years in so many places “adoration of the Most Holy Sacrament is also an important daily practice and becomes an inexhaustible source of holiness”, although there are also places “where there is evident almost a total lack of regard for worship in the form of eucharistic adoration.”
[137.] Exposition of the Most Holy Eucharist must always be carried out in accordance with the prescriptions of the liturgical books. Before the Most Holy Sacrament either reserved or exposed, the praying of the Rosary, which is admirable “in its simplicity and even its profundity”, is not to be excluded either. Even so, especially if there is Exposition, the character of this kind of prayer as a contemplation of the mystery of the life of Christ the Redeemer and the Almighty Father’s design of salvation should be emphasized, especially by making use of readings taken from Sacred Scripture.
[138.] Still, the Most Holy Sacrament, when exposed, must never be left unattended even for the briefest space of time. It should therefore be arranged that at least some of the faithful always be present at fixed times, even if they take alternating turns.
[139.] Where the diocesan Bishop has sacred ministers or others whom he can assign to this purpose, the faithful have a right to visit the Most Holy Sacrament of the Eucharist frequently for adoration, and to take part in adoration before the Most Holy Eucharist exposed at least at some time in the course of any given year.
[140.] It is highly recommended that at least in the cities and the larger towns the diocesan Bishop should designate a church building for perpetual adoration; in it, however, Holy Mass should be celebrated frequently, even daily if possible, while the Exposition should rigorously be interrupted while Mass is being celebrated. It is fitting that the host to be exposed for adoration should be consecrated in the Mass immediately preceding the time of adoration, and that it should be placed in the monstrance upon the altar after Communion.
[141.] The diocesan Bishop should acknowledge and foster insofar as possible the right of the various groups of Christ’s faithful to form guilds or associations for the carrying out of adoration, even almost continuous adoration. Whenever such associations assume an international character, it pertains to the Congregation for Divine Worship and the Discipline of the Sacraments to erect them and to approve their statutes.
