3. 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.
[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 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”.
[99.] Communion under both kinds is always permitted “to Priests who are not able to celebrate or concelebrate Mass”.
