Many pastors throughout the United States bless a large quantity of water on Holy Saturday, and urge the people to take some of it home for use during the year. Is there any authority for this? From the few rubrics available to the ordinary priest it seems that this water is to be used only on Holy Saturday for sprinkling the people and their homes, and on Easter for the "Vidi aquam". May this water be used on Holy Saturday for the Blessing of the "Indumenta Sacerdotalia" ?
The water blessed on Holy Saturday, and set apart before the holy chrism is added for the blessing of the Paschal Candle, is in the first instance intended to be used for the blessing of the people and their homes and belongings on Holy Saturday and Easter. This is plainly indicated in the Roman Ritual (Cap. " Benedictio Domorum in Sabbato Sancto Paschae"). Symbolically it corresponds to the rite which preceded the first Pasch of the Israelites, in which they and the door posts of their homes were sprinkled with the blood of the lamb, as it prefigured the freedom of the faithful from the bondage of Satan, through Baptism in Christ. The rubrics of the Mass, at the blessing of the baptismal font, prescribe that one of the attendant ministers take some of this water in a separate vessel for the purpose of blessing the houses and other places.
There is nothing to prohibit the preservation of this blessed water for the purpose of renewing the application of the sacramental graces. These are a call or invitation to the angel of God, as the prayer used in the blessing indicates, to guard, protect, and favor the inhabitants, and a petition that health, chastity, and every virtue may be the fruit of the repeated blessing. (Cf. " Benedictio Domorum, Loci, Thalami," etc., Rom. Rit.).
Since, however, similar blessings of water take place, not only on great festivals like the Epiphany, Pentecost, St. John Baptist's, but on every Sunday during the year, there is no need of attributing an exclusive virtue to the Easter water.
For the rest, we have the testimony of early Christian writers like St. Chrysostom (Oratio de Bapt. Christi., Op. torn. II, 366), that the faithful frequently kept this blessed water during the course of the year. It may be used for any blessing of worthy objects by the priest.
