The CDWDS addresses in three short sections “The Communion of Priests.”
[97.] A Priest must communicate at the altar at the moment laid down by the Missal each time he celebrates Holy Mass, and the concelebrants must communicate before they proceed with the distribution of Holy Communion. The Priest celebrant or a concelebrant is never to wait until the people’s Communion is concluded before receiving Communion himself. [Cf. Sacrosanctum Concilium 55; GIRM 158-160, 243-244, 246]
The impulse to wait for the end of the communion procession is perhaps something of an attempt to be polite, to get the smell of sheep. I can’t be sure, as no pastor I’ve ever worked for has done it. It was perceived to be a problem, I suppose.
[98.] The Communion of Priest concelebrants should proceed according to the norms prescribed in the liturgical books, always using hosts consecrated at the same Mass [Cf. GIRM 237-249; cf. also nn. 85, 157] and always with Communion under both kinds being received by all of the concelebrants. It is to be noted that if the Priest or Deacon hands the sacred host or chalice to the concelebrants, he says nothing; that is to say, he does not pronounce the words “The Body of Christ” or “The Blood of Christ”.
Did any of you know this was spelled out? I’ve rarely been close enough to notice.
[99.] Communion under both kinds is always permitted “to Priests who are not able to celebrate or concelebrate Mass”. [Cf. GIRM 283a]
I wonder how this is coordinated if the “priest in the pew” makes himself known. I imagine it happens more frequently in retirement days, possibly even outside of Mass.
I’m sure there’s an American sense of fairness that gets bruised with these insistences on behalf of clergy that seem lacking at times for lay people in some places and situations. I don’t get as bothered about such things anymore, but that could just be my golden situation. What about anyone else?
