Chapter 21 — Part II: The Sacraments — Holy Orders
Section 41. Acolyte — The fourth degree is that of acolytes, and it is the last of the orders that are called minor and not sacred. Their duty is to attend and serve the ministers who are in major orders, that is, the deacon and subdeacon, in the Sacrifice of the altar. They also carry and attend to the lights during the celebration of the Sacrifice of the Mass, and especially during the reading of the Gospel, from which fact they are also called candle-bearers.
