From the General Instruction of the Roman Missal:
“279. The sacred vessels are purified by the Priest, the Deacon, or an instituted acolyte after Communion or after Mass, insofar as possible at the credence table.” This is under the heading “IV. SOME GENERAL NORMS FOR ALL FORMS OF MASS”. Under the heading “II. CONCELEBRATED MASS” it has:
“249. … Moreover, the Deacon consumes at the altar all that remains of the Precious Blood, assisted, if the case requires, by some of the concelebrants. He carries the chalice to the credence table and there he or a duly instituted acolyte purifies it, wipes it, and arranges it as usual.”
Under the heading “C) THE FUNCTIONS OF THE ACOLYTE” it has:
“192. Likewise, after the distribution of Communion is complete, a duly instituted acolyte helps the Priest or Deacon to purify and arrange the sacred vessels. In the absence of a Deacon, a duly instituted acolyte carries the sacred vessels to the credence table and there purifies them, wipes them and arranges them as usual.”
Only men can be instituted as acolytes, not women.
