Any vessel touched by the Sacred Species, including the chalice, the ciborium, the paten, the communion paten, the pyx, and the luna.

The sacred vessels should be treated with the utmost reverence and handled sparingly, and even then only by the clergy, instituted acolytes, and members of the altar guild in connection with their pious usage, care, and cleaning.

At mass, the sacred vessels are placed on the credence table before mass by a member of the altar guild, and removed by the altar guild afterward.

At the preparation of the altar and the Ablutions, the sacred vessels are moved between the altar and the credence table by the acolyte, or in the absence of the acolyte by the deacon or celebrant.
