Found the 1975 (second edition of the Roman Missal of Pope Paul VI) General Instruction of the Roman Missal (GIRM) online and found some interesting things.
He then takes the paten or a ciborium and goes to the communicants. If communion is given only under the form of bread, he raises the eucharistic bread slightly and shows it to each one, saying: “The body of Christ.” The communicants reply: “Amen” and, holding the communion plate under their chin, receive the sacrament.
If there is no deacon, other priest, or acolyte:
a. The priest receives the Lord’s body and blood as usual, making sure enough remains in the chalice for the other communicants. He wipes the outside of the chalice with the purificator.
b. The priest then stations himself conveniently for communion and distributes the body of Christ in the usual way to all who are receiving under both kinds. The communicants approach, make the proper reverence, and stand in front of the priest. After receiving the body of Christ, they step back a little.
c. After all have received, the celebrant places the ciborium on the altar and takes the chalice with the purificator.** All those receiving from the chalice come forward again** and stand in front of the priest. He says: “The blood of Christ,” the communicant answers: Amen, and the priest presents the chalice with purificator. The communicants hold the purificator under their mouth with one hand, taking care that none of the precious blood is spilled, drink a little from the chalice, and then return to their place. The priest wipes the outside of the chalice with the purificator.
d. After the communion from the chalice, the priest places it on the altar and if there are others receiving under one kind only, he gives them communion in the usual way, then returns to the altar. He drinks whatever remains in the chalice and carries out the usual purifications.
It also talks about (for Communion under both kinds) intinction, tube, spoon.
The 2011 GIRM states
118. Likewise these should be prepared: …the Communion-plate for the Communion of the faithful…
The above is in Redemptionis Sacramentum too.
[93.] The Communion-plate for the Communion of the faithful should be retained, so as to avoid the danger of the sacred host or some fragment of it falling.
The 2011 GIRM also states
162. In the distribution of Communion the Priest may be assisted by other Priests who happen to be present. If such Priests are not present and there is** a truly large number of communicants,** the Priest may call upon extraordinary ministers to assist him, that is, duly instituted acolytes or even other faithful who have been duly deputed for this purpose. In case of necessity, the Priest may depute suitable faithful for this single occasion.
These ministers should not approach the altar before the Priest has received Communion, and they are always to receive from the hands of the Priest Celebrant the vessel containing the species of the Most Holy Eucharist for distribution to the faithful.
Does your Parish use the communion plate?
How many faithful present for your Parish to use EMHC
Do the EMHC come after the Priest’s Communion, or as I see often, after the Agnus Dei/Lamb of God?
