In several Christian denominations, such as Catholicism, Lutheranism, Anglicanism, Eastern Orthodoxy, Oriental Orthodoxy; holy water is water that has been sanctified by a priest for the purpose of baptism, for the blessing of persons, places, and objects, or as a means of repelling evil.
History
The Apostolic Constitutions, whose texts date to c. 400 AD, attribute the precept of using holy water to the Apostle Matthew. It is plausible that the earliest Christians may have used water for expiatory and purificatory purposes in a way analogous to its employment in Jewish Law ("And he shall take holy water in an earthen vessel, and he shall cast a little earth of the pavement of the tabernacle into it", Numbers 5:17). Yet in many cases, the water used for the sacrament of Baptism was flowing water, sea- or river-water, which — in the view of the Catholic Church — could not receive the same blessing as that water contained in the baptisteries. However, Eastern Orthodox Christians perform the same blessing, whether in a baptistery or at an outdoor body of water.
Use and storage Sprinkling with holy water is used as a sacramental that recalls baptism. In the West, the blessing of the water is traditionally accompanied by exorcism and by the addition of exorcised and blessed salt.
Holy water is kept in the holy water font, which is typically located at the entrance to the church (or sometimes in a separate room or building called a baptistery). Smaller vessels, called stoups, are usually placed at the entrances of the church, to enable people to bless themselves with it on entering. In the Middle Ages, Christians esteemed the power of holy water so highly that in some places fonts had locked covers to prevent the theft of holy water for unauthorized magic practices. The Constitutions of Archbishop Edmund Rich (1236) prescribe that: "Fonts are to be kept under lock and key, because of witchcraft (sortilege). Similarly the chrism and sacred oil are kept locked up."
In Catholicism, holy water, as well as the water used during the washing of the priest's hands at Mass, is not allowed to be disposed of in regular plumbing. Roman Catholic churches will usually have a special basin (a sacrarium) that leads directly into the ground for the purpose of proper disposal. A hinged lid is kept over the holy water basin to distinguish it from a regular sink basin, which is often just beside it. Items that contained holy water are separated, drained of the holy water, and then washed in a regular manner in the adjacent sink.
Hygiene Holy water fonts have been identified as a potential source of bacterial and viral infection. In the late-19th century, bacteriologists found staphylococci, streptococci, coli bacilli, Loeffler's bacillus, and other bacteria in samples of holy water taken from a church in Sassari, Italy. In a study performed in 1995, 13 samples were taken when a burn patient acquired a bacterial infection after exposure to holy water. The samples in that study were shown to have a "wide range of bacterial species", some of which could cause infection in humans. During the swine-flu epidemic of 2009, Bishop John Steinbock of Fresno, California, recommended that "holy water should not be in the fonts" for fear of spreading infections. Also in response to the swine flu, an automatic, motion-detecting holy-water dispenser was invented and installed in an Italian church in 2009. In 2020, because of the COVID-19 pandemic, Episcopal Conferences directed that holy water be removed from the fonts or stoups.
In Catholicism
Sacramental and sanctification A blessing, as a prayer, is a sacramental. By blessing water, Catholic priests praise God and ask for his grace. As a reminder of baptism, Catholic Christians dip their fingers in holy water and make the sign of the cross when entering a church. Fr. John F. Sullivan, writing in the early twentieth century, noted that, "Besides the pouring of baptismal water ... the sprinkling with holy water is a part of the ceremonies of Matrimony, of Extreme Unction and of the administration of the Holy Eucharist to the sick, and it is employed also in services for the dead." The Sunday liturgy may begin with the Rite of Blessing and Sprinkling Holy Water, in which holy water is sprinkled upon the congregation; this is called "aspersion" (from the Latin, aspergere, "to sprinkle"). This ceremony dates back to the 9th century. An "aspergill" or aspergillum is a brush or branch used to sprinkle the water. An aspersorium is the vessel which holds the holy water and into which the aspergillum is dipped, though elaborate Ottonian examples are known as situlae. Blessed salt may be added to the water where it is customary to do so. The Catholic Church teaches that this use of holy water and making a sign of the cross when entering a church reflects a renewal of baptism, a cleansing of venial sin, as well as providing protection against evil. It is sometimes accompanied by the following prayer:
By this holy water and by your Precious Blood, wash away all my sins, O Lord. Some Catholics believe that water from specific shrines (such as Lourdes) can bring healing – although that water is not the same as typical holy water found in parishes, since it has not been blessed by a priest.
Formula The traditional Latin formula for blessing the water is as follows:
