What is “CANTICUM”? This Beginning October 5, most Sundays there will be a small vocal (4 singers) called “Canticum” present for the 11:30 mass. On other Sundays, our musical worship at that mass will be led by the Archdiocesan Youth Choir or Students from Saint Cecilia Elementary School. Canticum means, “Song.” We bring ourselves, our joys, our sorrows and our hopes and express them through our responses. Singing our responses and prayers “heightens and unifies” our prayer to one voice. These singers are here to assist and support your sung prayer, the Assembled Body of Christ.
