My priest barely pours water into one chalice and swishes it in all four to cleanse. He consumes it and doesn’t wipe them out but passes them over to the Eucharistic Ministers to wipe out after Mass. Is this acceptable?
Purification, or cleansing of a vessel includes the addition of water (and, necessarily wine in the Extraordinary Form), the consumption of that water, and the careful wiping out of the chalice or ciborium. If the priest has other Eucharistic Ministers to assist him with the purification, no problem: Eucharistic Ministers, by definition, are bishops and priests with deacons as Ordinary Ministers of Communion. If, on the other hand, he is having Extraordinary Ministers of Holy Communion (EMHCs) assist him with the purification of the vessels at the altar or at the credence table, that would be an abuse. If he has an instituted Acolyte assist him with in the sacristy after Mass, that would be acceptable.
Under normal circumstances it is neither hard nor time consuming to purify a chalice and ciborium. This is done all the time. Father should do it on the spot, at the altar, after Communion. Alas, the often unnecessary multiplication of lay distributors of Communion also multiplies the hardware to be cleansed. Reduction or elimination of unnecessary of EMHCs would reduce the number of vessels to be purified, which could, in turn, help to reduce the temptation of committing other liturgical abuses in regard to their purification.
Also, Fathers, please do be careful and diligent in the purification of vessels! I occasionally find particles on patens and in ciboria and chalices that were clearly cleansed in a sloppy, inattentive manner.
Moreover, priests and sacristans alike should ensure that purificators are made of good and absorbent material, such as linen. Once in a while I am confronted with a purificator which seems to be made of Gortex or some other water repellent fabric. All they seem to do is push the droplets around.
Don’t skimp on altar linens. Get the good stuff.
