Parish youth in Grade 4 and up are invited to join this ministry. Altar Servers help the priest and the deacon during Mass, as well as completing other duties before Mass begins. Servers enhance the quality of celebration for the whole gathered assembly by taking part in processions and they participate not only in their distinctive ministerial functions but also together with the worshiping Assembly by singing, listening, responding and through their posture and gestures.
Each St. Leonard server is scheduled one weekend Mass about once a month, and after being trained, new servers are paired with more experienced servers for their first Masses in this important role.
