Asperges is a traditional Roman Catholic ritual that involves the sprinkling of holy water on the congregation as a reminder of baptism and purification. Typically performed during Mass, especially on certain feast days like Easter, it symbolizes renewal and the washing away of sin. The term “asperges” is derived from the Latin word "aspergere," meaning "to sprinkle." The rite often includes the chanting of Psalm verses, enhancing its liturgical significance.
