The Communion Hymn

This action by Christ's body, the Church assembled for the Eucharist, is manifested and supported by the Communication Hymn, a hymn in praise of Christ sung by the united voices of those who believe in him and share his life. The General Instruction of the Roman Missal takes this hymn very seriously, mandating that it should begin at the Communion of the priest and extend until the last person has received Communion.
For some, however, the singing of this hymn is perceived as an intrusion on their own prayer, their private thanksgiving after Communion. In fact, however, this hymn is prayer, the corporate thanksgiving prayer of the members of Christ's Body, united with one another. Over and over again the prayers of the liturgy and the norms of the General Instruction emphasize this fundamental concept of the unity of the baptized, stressing that when we come together to participate in the Eucharistic celebration we come, not as individuals, but as united members of Christ's body. In each of the Eucharistic Prayers, though the petition is worded in slightly different ways, God is asked to send his Holy Spirit to make us one body, one spirit in Christ; the General Instruction admonishes the faithful that they should become one body, whether by hearing the word of God, or joining in prayers and liturgical song.. (n.96) it describes one of the purposes of the opening song of the Mass as to ...intensify the unity of those who have assembled and says of the Communion Song that its function is to express outwardly the communicants' union in spirit by means of the unity of their voices, ...and to highlight the 'communitarian' character of the Communion Procession.

Communion as an Act of Unity

It is difficult for some of us to embrace this emphasis on Mass as the action of a community rather than an individual act of my own faith and piety, but it is important that we make every effort to do so. Christ himself at the Last Supper pleaded with his Father: Holy Father, keep those you have given me true to your name, so that they may be one like us... Father may they be one in us, as you are in me and I am in you.. Jn. 17:11;21. Baptism has joined us to Christ and to one another as the vine and its branches. The life of Christ, the Holy Spirit, animates each of us individually, and all of us corporately and guides us together in our efforts to become one Christ.
Finally, the fact that the Communion Procession is a profoundly religious action tells us something about the way in which we should participate in this procession. We are the Body of Christ, moving forward to receive the Christ who makes us one with himself and with one another. Our procession should move with dignity; our bearing should be that of those who know they have been redeemed by Christ and are coming to receive their God!

The Posture and Sign of Reverence for Receiving Communion

The new edition of the General Instruction asks the Conference of Bishops in each country to determine the posture to be used for the reception of Communion and the act of reverence to be made by each person as he or she receives Communion. The Conference of Bishops in Canada has determined that in this country Communion will be received standing and that a bow will be the act of reverence made by those receiving communion. This act of reverence is to be made in procession just before it is your turn to receive the Body of the Lord and just before it is your turn to leave receive the Precious Blood. The diocesan bishop may also determine the posture following the Lamb of God (Agnus Dei) when the priest shows the Body and Blood of the Lord to the people. After the communion procession ends, when the priest sits, all sit or kneel for a significant period of religious silence to meditate on the great gift they have received in the Eucharist. These norms may require some adjustment on the part of those who have been used to other practices, however the significance of unity in posture and gesture is a symbol of our unity as members of the one body of Christ should be the governing factor in our own actions.

How To Receive Communion

Those who receive Communion may receive either in the hand or on the tongue, and the decision should be that of the individual receiving, not of the person distributing Communion. If Communion is received in the hand, the hands should first of all be clean. If one is right-handed the left hand should rest upon the right. The host will then be laid in the palm of the left hand and then taken by the right hand to the mouth. If one is left-handed this is reversed. It is not appropriate to reach out with the fingers and take the host from the person distributing.
The person distributing Communion says audibly to each person approaching, "The Body of Christ". This formula should not be altered, as it is a proclamation which calls for the response of faith on the part of the one who receives. The communicant should audibly respond "Amen" indicating by that response his or her belief that this small wafer of bread, the wine in this chalice are in reality the body and blood of Christ the Lord.
When one receives from the chalice, the same proclamation is made by the person distributing Communion and the communicant again responds "Amen". It should be noted that it is never permissible for a person to dip the host he or she has received into the chalice. If, for some reason, the communicant is not able or willing to drink from the cup than that person should receive only under the form of bread.

After receiving communion all return to their place and continue singing the communion hymn until all have received and the priest sits down after any remaining host are reserved in the tabernacle. Then all sit or kneel for a period of religious silence. The assembly may then stand and join in singing a hymn of praise if desired. The Communion Rite concludes with the prayer after communion.

It seems appropriate to conclude this reflection on the Communion Procession and the reception of Communion with a quotation from the Catechism of the Catholic Church:

In Baptism we have been called to form but one body. The Eucharist fulfills this call: "The cup of blessing in which we bless, is it not participation in the blood of Christ? The bread which we break, is it not participation in the body of Christ? Because there is one breed, we who are many are one body, for we all partake of the one bread (1 Cor 10:16,17)"

If you are the body and members of Christ, then it is your sacrament that is placed on the table of the Lord: it is your sacrament that you receive. To that which you are you respond, "Amen" ("yes, it is true!") and by responding to it you assent to it. For you hear the words, "The Body of Christ" and respond to them "Amen." Be then a member of the Body of Christ that your Amen be true. (St. Augustine) CCC n.1936
