The Altar Server assists the priest and deacon in carrying out their ministry. The various tasks include: carrying the processional candles in the opening and closing processions; assisting with the book of prayers (Sacramentary) when the presider (priest) needs to read from it; helping to set the altar table; assisting with incense when used during Mass. Altar Servers should participate fully in the Mass by singing, listening, and keeping good silence. They are to be attentive to the priest and deacon at all times in case any special need arises. Training is provided and new servers are initially paired with veteran servers until they feel comfortable in the ministry.
