I noticed that the title of this post is incorrect: “Lay mininsters may not cleanse Communion vessels, Pope Benedict says”.
An instituted acolyte is a lay minister. He has not been ordained. An instituted acolyte may cleanse the Communion vessels.
From the 2002 General Introduction to the Roman Missal (GIRM) which can be accessed from
romanrite.com/girm.html :
“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.”
So the CNS headline was also incorrect. The CNS story has: “with instituted acolytes being permitted in the Roman Missal to help the priest or deacon “to purify and arrange the sacred vessels.””
But the insituted acolyte can do the purifications on his own. More quotes from the GIRM on this:
“192. Likewise, when the distribution of Communion is completed, a duly instituted acolyte helps the priest or deacon to purify and arrange the sacred vessels. When no deacon is present, a duly instituted acolyte carries the sacred vessels to the credence table and there purifies, wipes, and arranges them in the usual way.”
“247. The deacon reverently drinks at the altar all of the Blood of Christ that remains, assisted, if necessary, by some of the concelebrants. He then carries the chalice over to the credence table and there he or a duly instituted acolyte purifies, wipes, and arranges it in the usual way (cf. above, no. 183).”
“249. … The deacon, however, consumes at the altar all that remains of the Precious Blood, assisted, if necessary, by some of the concelebrants. He carries the chalice to the credence table and there he or a duly instituted acolyte purifies, wipes and arranges it in the usual way.”
“284. … b. Whatever may remain of the Blood of Christ is consumed at the altar by the priest or the deacon or the duly instituted acolyte who ministered the chalice. The same then purifies, wipes, and arranges the sacred vessels in the usual way.”
