Priest - "I will
go unto the Altar of God."
Server - "Even unto the God of my joy and gladness."
-from the Preparation for Mass (Psalm 43)
Although the term "Acolyte" means one who carries a torch lighting the path of the cross in processions, the term is also used to mean anyone who helps the clergy during a service. Acolytes may be asked to perform any jobs for which they are trained. Acolytes may also be called on to "run errands" (move something, hold something or otherwise assist) during the service. Their training and experience allow them to do this without being conspicuous or interrupting the worship.
