Acolyte

An acolyte is an assistant or follower assisting the celebrant in a religious service or procession. In many Christian denominations, an acolyte is anyone performing ceremonial duties such as lighting altar candles. In others, the term is used for one who has been inducted into a particular liturgical ministry, even when not performing those duties.
The word acolyte is derived from the Greek word ἀκόλουθος (akolouthos), meaning an attendant, via Late Latin acolythus.
