A sacristan is an officer who is charged with the care of the
sacristy, the
church, and their contents. In ancient times many duties of the sacristan were performed by the doorkeepers (ostiarii), later by the mansionarii and the treasurers. The Decretals of
Gregory IX (lib. I, tit. xxvi, "De officio sacristæ speak of the sacristan as if he had an honourable office attached to a certain benefice, and say that his duty was to care for the sacred vessels, vestments, lights, etc. Nowadays the sacristan is elected or appointed. The "Cæremoniale episcoporum" prescribed that in
cathedral and collegiate churches the sacristan should be a
priest, and describes his duties in regard to the sacristy, the Blessed
Eucharist, the
baptismal font, the
holy oils, the sacred
relics, the decoration of the church for the different seasons and feasts, the preparation of what is necessary for the various ceremonies, the pregustation in pontifical
Mass, the ringing of the church bells, the preservation of order in the church, and the distribution of Masses; and finally it suggests that one or two canons be appointed each year to supervise the work of the sacristan and his assistants.
