"Sanctus" is a Latin term meaning "holy" or "sacred." It is often used in religious contexts, particularly in Christian liturgy, where it refers to a hymn that praises God. The Sanctus is typically part of the Eucharistic prayer during Mass, expressing the congregation's reverence and worship. In music, "Sanctus" has been set to various compositions by notable composers, including Johann Sebastian Bach and Wolfgang Amadeus Mozart. These musical settings often enhance the spiritual experience of the text, allowing worshippers to engage more deeply with the themes of holiness and divine presence.
