As I have posted in another thread (#21 of
forums.catholic-questions.org/showthread.php?t=593313&page=2 ):
From the 2002 General Instruction of the Roman Missal (GIRM) approved for the USA, which can be accessed from
romanrite.com/girm.html :
“287. If Communion from the chalice is carried out by intinction, each communicant, holding a communion-plate under the chin, approaches the priest, who holds a vessel with the sacred particles, a minister standing at his side and holding the chalice. The priest takes a host, dips it partly into the chalice and, showing it, says, Corpus et Sanguis Christi (The Body and Blood of Christ). The communicant responds, Amen, receives the Sacrament in the mouth from the priest, and then withdraws.”
Here is the description of the normal manner of receiving Communion, from the GIRM:
“161. If Communion is given only under the species of bread, the priest raises the host slightly and shows it to each, saying, Corpus Christi (The Body of Christ). The communicant replies, Amen, and receives the Sacrament either on the tongue or, where this is allowed and if the communicant so chooses, in the hand. As soon as the communicant receives the host, he or she consumes it entirely.”
In both cases the Communion Minister is described as “the priest”. But lay people can also be the communion ministers. From the GIRM:
“100. In the absence of an instituted acolyte, lay ministers may be deputed to serve at the altar and assist the priest and the deacon; they may carry the cross, the candles, the thurible, the bread, the wine, and the water, and they may also be deputed to distribute Holy Communion as extraordinary ministers.”
So my understanding is that lay people can distribute communion, including by intinction, as extraordinary ministers.
Newly posted:
Maybe tomorrow the Pope will approve a document saying something like deacons and extraordinary ministers, in the Ordinary Form of the Roman Rite, may distribute the Precious Blood and the consecrated hosts, but not the two together in the form of intinction. But I am not aware of an official document that has this very specific instruction, the reasoning of which would be difficult to understand given the Eastern Rite practice.
