Asperges

Asperges is the rite of sprinkling a congregation with holy water. The name comes from the first word in the 9th verse of Psalm 51 (Psalm 50 in the Vulgate and Septuagint) in the Latin translation which is sung during the traditional form of the rite (or optionally in the ordinary rite) except during Eastertide. The 51st Psalm is also one of the antiphons that may be sung in the rite under the Mass of Paul VI.

Where the 1962 Latin Missal is used, the Asperges is done before the principal Mass on Sunday, except on Palm Sunday, when it is replaced with the blessing of palms followed by a procession; it is also omitted when a Pontifical High Mass is celebrated on Sundays. The Asperges is so called from the words intoned at the beginning of the ceremony, taken from Psalm 50:3, throughout the year except at Eastertide, when Vidi aquam (based on Ezechiel 47), with Psalm 116:1, is intoned. It precedes every other ceremony that may take place before the Mass, such as the blessing of palms or of candles. It is performed by the celebrant priest wearing a cope of the liturgical color of the day. It is omitted when the Blessed Sacrament is exposed, though many rubricists think that the sprinkling of the altar only, not of the congregation, should then be omitted. After intoning the antiphon the priest recites the psalm Miserere or Confitemini, according to the season, sprinkling first the front and platform of the altar, then himself, next the ministers and choir, and lastly the congregation, usually walking through the main part of the church, though he need not go beyond the gate of the sanctuary or choir. The ceremony has been in use at least from the tenth century, growing out of the custom of early antiquity of blessing water for the faithful on Sundays. Its object is to prepare the congregation for the celebration of the Mass by moving them to sentiments of penance and reverence suggested by the words of the 50th psalm, or by impressing on them that they are about to assist at the sacrifice of our redemption as suggested in the psalm used at Easter time.

Both the Asperges and the Vidi aquam are structured like the Introit of the Tridentine Mass: 1st verse (which includes Alleluias in Eastertide), 2nd verse (always from the Psalms), Gloria Patri (omitted in Passiontide), and then the 1st verse again.

"On Sundays, especially in Eastertide, the blessing of holy water and sprinkling with it may be carried out in memory of baptism. ... If the rite is performed within Mass it takes the place of the usual penitential act at the beginning of the Mass."

During the Easter Vigil, Christmas, and the Feast of the Baptism of the Lord, many Catholic parish Masses reserve a part of the Mass during which the Confiteor or tropes may be said (at the start of the Mass) to renew the Baptismal promises; this may be accompanied by the use of holy water to bless the congregation. This Renewal of Baptismal Vows, along with Asperges, is common among Lutherans and Anglicans as well. During the Funeral Mass, the casket is blessed with holy water and incense.

The priest blesses the water with one of the three prayers proposed (one of which is reserved for Eastertide). He may also bless salt and put it in the water, if local conditions or custom of the people favours doing so. Then he takes a sprinkler (called an aspergillum, while the container it is dipped into is called an aspersorium), and sprinkles the clergy and people, preferably walking through the church to do so.

While the sprinkling is being done, an antiphon or a hymn is sung. The Roman Missal proposes several, based on the following verses of Scripture:

But other suitable hymns are permitted.
