“The following also exercise a liturgical function: The sacristan, who carefully arranges the liturgical books, the vestments, and other things necessary in the celebration of Mass.” ~GIRM, No. 105
The sacristan, always under the general direction of the clergy, undertakes the overall preparation of liturgical celebrations, including all that is needed for special days such as Ash Wednesday and Palm Sunday. The sacristan thus arranges the books needed for the celebration, marking all of the divisions. He or she lays out the vestments and anything else needed for the celebration, such as cruets, chalices, ciboria, linens, oils, processional crosses, candles and torches. He or she also takes care of the ringing of bells that announce the celebrations in the absence of an altar server. The sacristan should ensure the observance of silence in the sacristy.
The sacristan in harmony with the pastor also makes sure that the vestments, church furnishings, liturgical vessels and decorative objects are kept in good condition and, if necessary, sent for gilding or repair. Other practical indications apart from these official recommendations are that the sacristan ensures that the things necessary for worship are always available. There should be a ready supply of fresh hosts and of duly authorized wine, sufficient clean purificators, corporals, hand towels, incense and coals. In this context the sacristan is responsible for making sure that those who wash the altar linens do so according to the indications of the missal and that the water for the first wash is poured down the sacrarium or to the earth. The sacristan also takes care of burning old linens and other objects that are no longer suitable for liturgical use.
