Instruction on Eucharistic Worship - Sacred Congregation of Rites 1967 (Conclusion)

VI. Eucharistic Congresses

67. In Eucharistic congresses Christians seek to understand this mystery more deeply through a consideration of its many aspects (cf. above, no. 3). But they should celebrate it in accordance with the norms of the Second Vatican Council and should venerate it through devotions and private prayers, especially by solemn processions, in such a way that all these forms of devotion find their climax in the solemn celebration of Mass.

For the duration of the Eucharistic congress of an entire region, it is fitting that some churches should be reserved for perpetual adoration.

In the audience granted on the 13th of April, 1967, to His Eminence Arcadio M. Cardinal Larraona, Prefect of the Sacred Congregation of Rites, His Holiness Pope Paul VI, by his authority approved and confirmed this instruction, ordered that it should be published, and established that it should come into effect on the feast of the Assumption of the Blessed Virgin Mary, 15 August 1967.

All things to the contrary notwithstanding.

Rome, 25th May, 1967, the Feast of Corpus Christi.

65. Interrupting Exposition
 

If, because there is not a suitable number of faithful for the adoration of the Blessed Sacrament, continuous exposition is not possible, it is permissible to replace the Host in the tabernacle, at pre-arranged and publicized times. This should not be done however more than twice in a day, for example, at midday and at night.
This reposition may be carried out in the more simple way and without singing: the priest dressed in surplice and stole, having adored the Blessed Sacrament for a short time, replaces it in the tabernacle. In the same way, at a set time, the Blessed Sacrament is again exposed; the priest retires after a short period of adoration.

66. Exposition for Short Periods

Even brief exposition of the Blessed Sacrament, held in accordance with the law, should be so arranged that before the blessing with the Blessed Sacrament reasonable time is provided for readings of the Word of God, hymns, prayers, and silent prayer, as circumstances permit.
Local Ordinaries will make certain that these expositions of the Blessed Sacrament are always and everywhere carried out with due reverence.

Exposition merely for the purpose of giving Benediction after Mass is forbidden.

62. How the Rite of Exposition Is to Be Carried Out

If the exposition is to be only a short one, then the monstrance or ciborium should be placed on the altar table. If exposition is over a longer period, then a throne may be used, placed in a prominent position; care should be taken, however, that it is not too high or far away.

During the exposition everything should be so arranged that the faithful can devote themselves attentively in prayer to Christ our Lord.
To foster personal prayer, there may be readings from the Scriptures together with a homily, or brief exhortations which lead to a better understanding of the Mystery of the Eucharist. It is also good for the faithful to respond to the Word of God in song. It is desirable that there should be periods of silence at suitable times.
At the end of exposition, Benediction with the Blessed Sacrament is given.
If the vernacular is used, instead of singing the <Tantum Ergo> before the blessing, another Eucharistic hymn may be used, as laid down by the episcopal conference.

63. Solemn Annual Exposition

In churches where the Blessed Sacrament is normally reserved, there may be a protracted period of solemn exposition each year, even if not strictly continuous, giving the local community the opportunity to adore and meditate on this mystery more deeply and fervently.
Exposition of this kind should be held only if it is seen that there will be a reasonable number of the faithful, with the consent of the local Ordinary and according to the law.

64. Prolonged Exposition

For any grave and general need, the local Ordinary can order that there should be prayer before the Blessed Sacrament exposed over a long period, which may be strictly continuous, in those churches where there are large numbers of the faithful.

55. A Tabernacle on an Altar where Mass is Celebrated with a Congregation

In the celebration of Mass the principal modes of worship by which Christ is present to His Church116 are gradually revealed. First of all, Christ is seen to be present among the faithful gathered in His name; then in his Word, as the Scriptures are read and explained; in the person of the minister; finally and in a unique way (modo singular)) under the species of the Eucharist. Consequently, because of the sign, it is more in keeping with the nature of the celebration that the Eucharistic presence of Christ, which is the fruit of the consecration and should be seen as such, should not be on the altar from the very beginning of Mass through the reservation of the sacred species in the tabernacle.

56. The Tabernacle in the Construction of New Churches and the Adaptation of Existing Churches and Altars
The principles stated in nos. 53 and 55 ought to be kept in mind in the building of new churches.
The adaptation of existing churches and altars may take place only according to the principles laid down in no. 24 of this instruction.

57. The Means of Indicating the Presence of the Blessed Sacrament in the Tabernacle
Care should be taken that the presence of the Blessed Sacrament in the tabernacle is indicated to the faithful by a tabernacle veil or some other suitable means prescribed by the competent authority.
According to the traditional practice, a lamp should burn continually near the tabernacle as a sign of the honor paid to the Lord.117
