The Communion rite
All together recite or sing the "Lord's Prayer" ("Pater Noster" or "Our Father"). The priest introduces it with a short phrase and follows it up with the prayer: "Deliver us, Lord, from every evil, and grant us peace in our day. In your mercy keep us free from sin and protect us from all anxiety as we wait in joyful hope for the coming of our Savior, Jesus Christ." The people then add the doxology: "For the kingdom, the power, and the glory are yours, now and forever."
Next comes the rite of peace (pax). After praying: "Lord Jesus Christ, you said to your apostles: 'I leave you peace, my peace I give you.' Look not on our sins, but on the faith of your Church, and grant us the peace and unity of your kingdom where you live for ever and ever ", the priest wishes the people the peace of Christ: "The peace of the Lord be with you always." The deacon or, in his absence, the priest may then invite those present to offer each other the sign of peace. The form of the sign of peace varies according to local custom. A handshake is common in many countries, including the United States. In India a person will give the sign of peace by joining his or her hands and bowing to another. In the Philippines the sign of peace is usually a smile and a polite nod.
While the "Lamb of God" ("Agnus Dei" in Latin) litany is sung or recited, the priest breaks the host and places a piece in the main chalice; this is known as the rite of fraction and commingling.
If extraordinary ministers of Holy Communion are required, they may come forward at this time, but they are not allowed to go to the altar itself until after the priest has received Communion (General Instruction of the Roman Missal, 162). The priest then presents the transubstantiated elements to the congregation, saying: "This is the Lamb of God who takes away the sin of the world. Happy are those who are called to his supper." Then all repeat: "Lord, I am not worthy to receive you, but only say the word and I shall be healed." The priest then receives Communion and, with the help, if necessary, of extraordinary ministers, distributes Communion to the people, who generally approach in procession. Before receiving, each communicant is supposed to make a sign of reverence, such as a bow. The distributing minister says: "The body of Christ" or "The blood of Christ", according as the element distributed is the consecrated bread or the consecrated wine, or: "The body and blood of Christ", if both are distributed together (by intinction). The communicant responds: "Amen." Catholic Eucharistic theology points out that, because Christ is not now divided, whoever receives only the bread that has become his body also receives his blood, together with his soul and divinity.
While Communion is distributed, an appropriate song is recommended. If that is not possible, a short antiphon is recited before the distribution begins.
"The sacred vessels are purified by the priest, the deacon, or an instituted acolyte after Communion or after Mass, insofar as possible at the credence table" (GIRM 279). Then the priest concludes the Liturgy of the Eucharist with the Prayer after Communion, for which the people are invited to stand.
