Chapter IV-C. Masses without a Congregation
209. This section gives the norms for Mass celebrated by a priest with only one server to assist him and to make the responses.
210. In general this form of Mass follows the rite of Mass with a congregation. The server takes the people's part to the extent possible.
211. Mass should not be celebrated without a server or the participation of at least one of the faithful, except for some legitimate and reasonable cause. In this case the greetings and the blessing at the end of Mass are omitted.
212. The chalice is prepared before Mass, either on a side table near the altar or on the altar itself; the missal is placed on the left side of the altar.
213. After he reverences the altar, the priest crosses himself, saying: In the name of the Father, etc. He turns to the server and gives one of the forms of greeting. For the penitential rite the priest stands at the foot of the altar.
214. The priest then goes up to the altar and kisses it, goes to the missal at the left side of the altar, and remains there until the end of the general intercessions.
215. He reads the entrance antiphon and says the Kyrie and the Gloria, in keeping with the rubrics.
216. Then, with hands joined, the priest says: Let us pray. After a suitable pause, he says the opening prayer, with hands outstretched. At the end the server responds: Amen.
Liturgy of the Word
217. After the opening prayer, the server or the priest himself reads the first reading and psalm, the second reading, when it is to be said, and the Alleluia verse or other chant.
218. The priest remains in the same place, bows and says inaudibly: Almighty God, cleanse my heart. He then reads the gospel and at the conclusion kisses the book, saying: MAy the words of the gospel wipe away our sins. The server says the acclamation.
219. The priest then says the profession of faith with the server, if the rubrics call for it.
220. The general intercessions may be said even in this form of Mass; the priest gives the intentions and the server makes the response.
Liturgy of the Eucharist
221. The antiphon for the preparation of the gifts is omitted. The minister places the corporal, purificator, and chalice on the altar, unless they have already been put there at the beginning of Mass.
222. Preparation of the bread and wine, including the pouring of the water, are carried out as at a Mass with a congregation., with the formularies given in the Order of Mass. After placing the bread and wine on the altar, the priest washes his hands at the side of the altar as the server pours the water.
223. The priest says the prayer over the gifts and the eucharistic prayer, following the rite described for Mass with a congregation.
224. The Lord's Prayer and the embolism, Deliver us, are said as at a Mass with a congregation.
225. After the acclamation concluding the embolism, the priest says the prayer, Lord Jesus Christ, you said. He then adds: The peace of the Lord be with you always, and the server answers: And also with you. The priest may give the sign of peace to the server.
226. Then, while he says the Agnus Dei with the server, the priest breaks the eucharistic bread over the paten. After the Agnus Dei, he places a particle in the chalice, saying inaudibly: May this mingling.
227. After the commingling, the priest says inaudibly the prayer, Lord Jesus Christ, Son of the living God, or Lord Jesus Christ, with faith in Your love and mercy. Then he genuflects and takes the eucharistic bread. If the server is to receive communion, the priest turns to him and, holding the eucharistic bread a little above the paten, says: This is the Lamb of God, adding once with the server: Lord I am not worthy. Facing the altar, the priest then receives the body of Christ. If the server is not receiving communion, the priest, after making a genuflection, takes the host and, facing the altar, says once inaudibly: Lord I am not worthy, and eats the body of Christ. The blood of Christ is received in the way described in the Order of Mass with a congregation.
228. Before giving communion to the server, the priest says the communion antiphon.
229. The chalice is washed at the side of the altar and then may be carried by the server to a side table or left on the altar, as at the beginning.
230. After the purification of the chalice, the priest may observe a period of silence. Then he says the prayer after communion.
231. The concluding rites are carried out as at Mass with a congregation, but the dismissal formulary is omitted.
