The sacristan lays out the vestments and anything else needed for the Mass or celebration, such as cruets, chalices, ciboria, linens, oils, processional crosses, candles and torches.

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.

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.
