What spiritual consequence does blessing or holy water have? Is it a symbolic gesture of faith to bless something or does it impart some sort of effect?
First, let’s start with the
Catechism:
1668 Sacramentals are instituted for the sanctification of certain ministries of the Church, certain states of life, a great variety of circumstances in Christian life, and the use of many things helpful to man. In accordance with bishops’ pastoral decisions, they can also respond to the needs, culture, and special history of the Christian people of a particular region or time. They always include a prayer, often accompanied by a specific sign, such as the laying on of hands, the sign of the cross, or the sprinkling of holy water (which recalls Baptism).
1669 Sacramentals derive from the baptismal priesthood: every baptized person is called to be a “blessing,” and to bless. Hence lay people may preside at certain blessings; the more a blessing concerns ecclesial and sacramental life, the more is its administration reserved to the ordained ministry (bishops, priests, or deacons).
1670 Sacramentals do not confer the grace of the Holy Spirit in the way that the sacraments do, but by the Church’s prayer, they prepare us to receive grace and dispose us to cooperate with it. “For well-disposed members of the faithful, the liturgy of the sacraments and sacramentals sanctifies almost every event of their lives with the divine grace which flows from the Paschal mystery of the Passion, Death, and Resurrection of Christ. From this source all sacraments and sacramentals draw their power. There is scarcely any proper use of material things which cannot be thus directed toward the sanctification of men and the praise of God.”
And here’s something I found in the
Catholic Encyclopedia:
One of the most remarkable effects of sacramentals is the virtue to drive away evil spirits whose mysterious and baleful operations affect sometimes the physical activity of man. To combat this occult power the Church has recourse to exorcism and sacramentals. Another effect is the delivery of the soul from sin and the penalties therefor. Thus in the blessing of a cross the Church asks that this sacred sign may receive the heavenly blessing in order that all those who kneel before it and implore the Divine Majesty may be granted great compunction and a general pardon of faults committed. This means remission of venial sins, for the sacraments alone, with perfect contrition, possess the efficacy to remit mortal sins and to release from the penalties attached to them. St. Thomas is explicit on this point: “The episcopal blessing, the aspersion of holy water, every sacramental unction, prayer in a dedicated church, and the like, effect the remission of venial sins, implicitly or explicitly” (Summa III, Q. lxxxvii, a. 3, ad 1um). Finally the sacramentals may be employed to obtain temporal favours, since the Church herself blesses objects made use of in every-day life, e.g. the blessing of a house on which is called down the abundance of heavenly dew and the rich fruitfulness of the earth; so likewise in the benediction of the fields, in which God is asked to pour down His blessings on the harvests, so that the wants of the needy may be supplied by the fertile earth.
Finally, here’s a link to a good article on sacramentals:
