From the 2004 Instruction Redemptionis Sacramentum: “[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.[footnote 180: Cf. Missale Romanum, Institutio Generalis, n. 118.]”
The footnote refers to the direction to have a communion-plate on the credence table at the beginning of Mass.
Part of the problem is that the instructions for using the communion-plate are unclear. Before the 2002 GIRM there were clear instructions in the 1975 GIRM:
“117. 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.”
Clearly the communicants hold the communion-plate under their chin. Despite this instruction it was not often followed. If the communion-plate was used (my impression is) that it was more likely to be held by an altar server than by the communicant.
This paragraph was replaced in 2002 GIRM with:
“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 the 2002 GIRM the communion-plate is only referred to in n. 118 and n. 287:
“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.”
So, again, no mention of an altar server holding the communion-plate, only the communicant.
So if a priest is to follow these instructions considerable training and instruction is necessary. The process would be something like:
- Person coming to communion indicates to altar server holding the communion-plate if they wish to receive in the hand or on the tongue.
- If in the hand, the communion-plate is not used.
- If on the tongue, the communicant holds communion-plate beneath their chin. The communion-plate is then given back to the altar server to hold the communion-plate.
