The Altar Server assists the members of the liturgical assembly by presenting or arranging vessels and other items used in the celebrations. Their reverent and efficient service enable other ministers to attend to their own roles while the liturgical actions unfold with calm, order and appropriate decorum. As members of the assembly who are often visible to all, the Altar Servers also model good liturgical participation. There are many tasks carried out by Altar Servers: carrying the cross, the processional candles, holding the book for the priest, carrying the incense and censer, presenting the bread, wine, and water to the priest, washing the hands of the priest and being called upon by the priest to assist where necessary. Since Altar Servers are often visible to all, they complete their tasks in a reverent, calm and orderly manner.
