Joh 6:53 B]
*15. The sacramental re-presentation of Christ’s sacrifice, crowned by the resurrection, in the Mass involves a most special presence which – in the words of Paul VI – “is called ‘real’ not as a way of excluding all other types of presence as if they were ‘not real’, but because it is a presence in the fullest sense: a substantial presence whereby Christ, the God-Man, is wholly and entirely present”.22 This sets forth once more the perennially valid teaching of the Council of Trent: “the consecration of the bread and wine effects the change of the whole substance of the bread into the substance of the body of Christ our Lord, and of the whole substance of the wine into the substance of his blood. And the holy Catholic Church has fittingly and properly called this change transubstantiation”.23 Truly the Eucharist is a mysterium fidei, a mystery which surpasses our understanding and can only be received in faith, as is often brought out in the catechesis of the Church Fathers regarding this divine sacrament: “Do not see – Saint Cyril of Jerusalem exhorts – in the bread and wine merely natural elements, because the Lord has expressly said that they are his body and his blood: faith assures you of this, though your senses suggest otherwise”.24
Adoro te devote, latens Deitas, we shall continue to sing with the Angelic Doctor. Before this mystery of love, human reason fully experiences its limitations. One understands how, down the centuries, this truth has stimulated theology to strive to understand it ever more deeply.
These are praiseworthy efforts, which are all the more helpful and insightful to the extent that they are able to join critical thinking to the “living faith” of the Church, as grasped especially by the Magisterium’s “sure charism of truth” and the “intimate sense of spiritual realities”25 which is attained above all by the saints. There remains the boundary indicated by Paul VI: “Every theological explanation which seeks some understanding of this mystery, in order to be in accord with Catholic faith, must firmly maintain that in objective reality, independently of our mind, the bread and wine have ceased to exist after the consecration, so that the adorable body and blood of the Lord Jesus from that moment on are really before us under the sacramental species of bread and wine”.26
- The saving efficacy of the sacrifice is fully realized when the Lord’s body and blood are received in communion. The Eucharistic Sacrifice is intrinsically directed to the inward union of the faithful with Christ through communion; we receive the very One who offered himself for us, we receive his body which he gave up for us on the Cross and his blood which he “poured out for many for the forgiveness of sins” (Mt 26:28). We are reminded of his words: “As the living Father sent me, and I live because of the Father, so he who eats me will live because of me” (Jn 6:57). Jesus himself reassures us that this union, which he compares to that of the life of the Trinity, is truly realized. The Eucharist is a true banquet, in which Christ offers himself as our nourishment. When for the first time Jesus spoke of this food, his listeners were astonished and bewildered, which forced the Master to emphasize the objective truth of his words: “Truly, truly, I say to you, unless you eat the flesh of the Son of Man and drink his blood, you have no life within you” (Jn 6:53). This is no metaphorical food: “My flesh is food indeed, and my blood is drink indeed” (Jn 6:55).
- Through our communion in his body and blood, Christ also grants us his Spirit. Saint Ephrem writes: “He called the bread his living body and he filled it with himself and his Spirit…
He who eats it with faith, eats Fire and Spirit… Take and eat this, all of you, and eat with it the Holy Spirit. For it is truly my body and whoever eats it will have eternal life”.27 The Church implores this divine Gift, the source of every other gift, in the Eucharistic epiclesis. In the Divine Liturgy of Saint John Chrysostom, for example, we find the prayer: “We beseech, implore and beg you: send your Holy Spirit upon us all and upon these gifts… that those who partake of them may be purified in soul, receive the forgiveness of their sins, and share in the Holy Spirit”.28 And in the Roman Missal the celebrant prays: “grant that we who are nourished by his body and blood may be filled with his Holy Spirit, and become one body, one spirit in Christ”.29 Thus by the gift of his body and blood Christ increases within us the gift of his Spirit, already poured out in Baptism and bestowed as a “seal” in the sacrament of Confirmation. * (ENCYCLICAL LETTER ECCLESIA DE EUCHARISTIA OF HIS HOLINESS POPE JOHN PAUL II TO THE BISHOPS PRIESTS AND DEACONS MEN AND WOMEN IN THE CONSECRATED LIFE AND ALL THE LAY FAITHFUL ON THE EUCHARIST IN ITS RELATIONSHIP TO THE CHURCH, excerpt from CHAPTER ONE, THE MYSTERY OF FAITH)
