Latin: sacer, sacred
Officers charged with the care of the sacristy, church, sacred vessels, etc. They prepare the vestments, altar vessels, and other things required by the ceremonial for any liturgical function. The Council of Trent desired that clerics should hold such offices, and this is complied with wherever possible, though the difficulty of obtaining clerics has often necessitated that laymen should discharge these duties. See also patrons of sacristans.
