what makes holy water holy

Holy water is made holy primarily through a blessing by a member of the clergy, such as a priest or bishop, who prays over the water to invoke God's grace and protection. In the Catholic tradition, holy water is often made by mixing blessed salt with water; the salt is exorcised and blessed to purify and protect. The blessing includes prayers and sometimes exorcisms to drive away evil spirits, protect against sickness, and sanctify those who use it. Holy water symbolizes purification, the cleansing of venial sins, protection from evil, and a reminder of baptism and spiritual renewal. It is considered a sacramental, meaning it obtains actual graces for the faithful through God's power, although it is not a sacrament itself. The spiritual efficacy of holy water lies in the blessing it receives and the faith of the user in God's grace working through it.
