Sancta Missa - Rituale Romanum (Roman Ritual) - Forty Hours' Adoration


Where the Forty Hours Adoration is Celebrated According to the Clementine Instruction


1. For the solemn exposition of the Blessed Sacrament in the Forty Hours prayer, first the solemn votive Mass of the Blessed Sacrament is celebrated according to the Instruction of the S. C. R., issued on April 7, 1927, which is likewise to be followed for the other Masses during this devotion. Consult also the new Code of Rubrics of July 26, 1960.

2. At the end of the solemn Mass the procession with the Blessed Sacrament is held inside the church, during which the hymn Sing, my tongue, the Saviour's glory is sung (see below), as far as the verse Down in adoration falling exclusive. The hymn may be repeated until the end of the procession.

3. At the end of the procession the Blessed Sacrament is exposed for adoration upon a throne, and then the two final verses of the hymn are sung. The celebrant incenses the Blessed Sacrament as usual.

{The music and organ accompaniment to the following hymn, Litany of the Saints, etc., are given in the music supplement.}

Hymn: Pange lingua

Sing, my tongue, the Savior's glory,

Of His flesh the mystery sing;

Of the blood, all price exceeding,

Shed by our immortal king,

Destined, for the world's redemption,

From a noble womb to spring.

Of a pure and spotless virgin

Born for us on earth below,

He, as man, with man conversing,

Stayed, the seeds of truth to sow;

Then He closed in solemn order

Wondrously His life of woe.

On the night of that Last Supper

Seated with His chosen band,

He, the paschal victim eating,

First fulfills the Law's command:

Then as food to all His Brethren

Gives Himself with His own hand.

Word made flesh, the bread of nature

By His word to flesh He turns;

Wine into His blood He changes:

What though sense no change discerns?

Only be the heart in earnest,

Faith her lesson quickly learns.

Down in adoration falling,

Lo! the sacred host we hail;

Lo! o'er ancient forms departing,

Newer rites of grace prevail;

Faith for all defects supplying,

Where the feeble senses fail.

To the everlasting Father,

And the Son who reigns on high,

With the Holy Spirit proceeding

Forth from Each eternally,

Be salvation, honor, blessing.

Might, and endless majesty. Amen.

4. At the end of the hymn the versicle and response are omitted. The chanters begin the litany at once with all present responding followed by psalm 69 and the versicles, as far as "The Lord be with you," etc., exclusive.

(See Litany of the Saints for litany). At the end of the Litany the celebrant stands and sings the orations:

Celebrant: The Lord be with you.

All: May He also be with you.

Let us pray.

God, who left us in this wondrous sacrament a memorial of your passion, help us, we beg you, so to reverence the sacred mysteries of your body and blood, that we may always experience the effects of your redemption.

From Advent Until Christmas

God, who willed that your Word take flesh in the womb of the blessed Virgin Mary at the Angel's message; grant that we, your petitioners, who believe she is truly the Mother of God, may be aided by her intercession.

From Christmas to the Purification

God, who brought to mankind the gift of eternal salvation through the virginal motherhood of blessed Mary; let us be helped by her prayers, since through her we have been favored with the source of life, our Lord Jesus Christ, your Son.

From the Purification to Easter and After Eastertime to Advent

We entreat you, Lord God, grant us, your servants, the enjoyment of lasting health of body and mind; and by the glorious intercession of blessed Mary, ever a Virgin, free us from present sorrow and give us everlasting joy.


God, who mercifully brought joy into the world by the resurrection of your Son, our Lord Jesus Christ; grant that we may come to the joy of everlasting life through the prayers of His Mother, the Virgin Mary.

Almighty everlasting God, be gracious to your servant, N., our sovereign Pontiff, and in your kindness lead him on the path of everlasting salvation; may he by your grace seek only that which pleases you and carry it out with all his might.

God, our refuge and our strength and source of all goodness, heed the holy prayers of your Church, and grant that we fully obtain whatever we ask for in faith.

Almighty everlasting God, who will the salvation of every man and would have no one perish; see how many souls are deceived by the wiles of the devil and how their hearts are gone astray; help them to escape the evils of heresy, to repent and to return to the unity of your truth.

Almighty everlasting God, Lord of both the living and the dead; deal mercifully with all whom you foresee shall be yours by faith and good works. Hear us, your lowly servants, and grant that those for whom we earnestly offer our prayers, whether this present world still detains them in the flesh or the world to come has already claimed their souls, may obtain pardon of all their sins, through your mercy and goodness and through the intercession of your saints. We ask this through our Lord Jesus Christ, your Son, who lives and reigns with you, in the unity of the Holy Spirit, God, forever and ever.

All: Amen.

P: Lord, heed my prayer.

All: And let my cry be heard by you.

P: May the almighty and merciful Lord graciously hear us.

All: And may He ever preserve us. Amen.

P: May the souls of the faithful departed through the mercy of God rest in peace.

All: Amen.

If the papacy is vacant, in place of the invocation "That you graciously preserve our Holy Father and all orders of the Church," etc., the invocation will be "That you graciously preserve all orders of the Church," etc. And the verse "Let us pray for our Sovereign Pontiff, N.," together with its response and prayer is omitted.


1. At the reposition of the Blessed Sacrament on the third day, after the celebration of the solemn votive Mass as on the first day, the celebrant removes his chasuble and maniple at the sedilia. Having put on the cope he returns to the altar, genuflects on both knees, and then kneels on the lowest step.

2. The Litany of the Saints is sung together with psalm 69 and the prayers that follow, as far as "The Lord be with you" exclusive. Then the Blessed Sacrament is taken from the throne and placed on the altar: having put incense in two thuribles for the procession, the celebrant incenses the Blessed Sacrament as usual.

3. Then the procession with the Blessed Sacrament takes place in church as on the first day, and the hymn "Sing my tongue" is sung as far as the verse "Down in adoration" exclusive.

4. At the end of the procession the Blessed Sacrament is placed on the altar table, and the chanters intone "Down in adoration" and all join in singing the last two verses. The celebrant again incenses the Blessed Sacrament as usual.

5. Afterward the versicle is sung:

Chanters: You have given them the bread of heaven (Alleluia).

All: Which has all delight within it (Alleluia).

Then the celebrant stands and sings Let us pray.

God, who left us in this wondrous sacrament, etc., and all the other prayers sung on the first day at exposition, up to and including May the souls, etc. Then the blessing with the Blessed Sacrament is given in the usual way and the sacred host is replaced in the tabernacle.
