The Order of Mass part of the 2002 Missale Romanum has:
“137. Distributione Communionis expleta, sacerdos vel diaconus vel acolythus purificat patenam super calicem et ipsum calicem.
Dum purificationem peragit, sacerdos dicit secreto:
Quod ore sumpsimus, …”.
(Missale Romanum, Libreria Editrice Vaticana, 2002, ISBN: 8820972719, page 602.)
Here’s what the 1985 Roman Missal has (in its appendix containing the Latin for the Novus Ordo ordinary):
138. Distributione Communionis expleta, sacerdoes vel diaconus purificat patenam super calicem et ipsum calicem.
Dum purificationem peragit, sacerdos dicit secreto:
Quod ore sumpsimus…
This is essentially identical with the 2002
Ordo Missae, with the exception of “vel acolythus”.
A translation of these words in a book I have “Daily Roman Missal” (Scepter Publishers, 1996, ISBN 0-933932-58-8, page 741) is:
“The vessels are cleansed by the priest or deacon or acolyte after the communion or after Mass, if possible at the side table. [footnote 18: General Instruction, no. 238.]
Meanwhile he says inaudibly:
Lord, may I receive …”.
Except that’s not a translation. Let me try:
The distribution of Communion being completed, the priest or the deacon [or the acolyte] purifies the paten over the chalice, and the chalice itself.
While the purification is being carried out, the priest says inaudibly: “That which we have taken by our mouths…”
So I am curious if the priest says the prayer, regardless of
who does the purification, or if
sacerdos dicit is shorthand for
sacerdos vel diaconus [vel acolythus] dicit, given the prescription for
who can do the actual purifying.
Granted, the 2002 GIRM (#279) says: “
Vasa sacra purificantur a sacerdote vel a diacono vel ab acolytho instituto post Communionem vel post Missam, quantum fieri potest ad abacum.” (“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.”) GIRM #163 also covers the purification in slightly more detail:
Sacerdos, ad altare reversus, colligit fragmenta, si quae sint; deinde, stans ad latus altaris vel ad abacum, purificat patenam vel pyxidem super calicem, postea purificat calicem, dicens secreto: Quod ore súmpsimus, et calicem purificatorio exterget. Si vasa purificata sunt ad altare, a ministro deferuntur ad abacum. Licet tamen vasa purificanda, praesertim si sint plura, opportune cooperta, in altari vel in abaco super corporale relinquere eaque statim post Missam, populo dimisso, purificare.
Upon returning to the altar, the priest collects any fragments that may remain. Then, standing
at the altar or at the credence table, he purifies the paten or ciborium over the chalice then purifies the chalice, saying quietly,
Quod ore sumpsimus (
Lord, may I receive), and dries the chalice with a purificator. If the vessels are purified at the altar, they are carried to the credence table by a minister. Nevertheless, it is also permitted, especially if there are several vessels to be purified, to leave them suitably covered on a corporal, either at the altar or at the credence table, and to purify them immediately after Mass following the dismissal of the people.
Here there is preference (by virtue of the order of the options) for the purification to take place
at Mass at the altar.
I find it unsettling, sometimes,
how much of the Mass is left up to the whim of the priest. There are so many options in the
Novus Ordo Mass.
