Mysterium Fidei
Christ Sacramentally Present in the Sacrifice of the Mass
34The few things that We have touched upon concerning the Sacrifice of the Mass encourage Us to say something about the Sacrament of the Eucharist, since both Sacrifice and Sacrament pertain to the same mystery and cannot be separated from each other. The Lord is immolated in an unbloody way in the Sacrifice of the Mass and He re-presents the sacrifice of the Cross and applies its salvific power at the moment when he becomes sacramentally present—through the words of consecration—as the spiritual food of the faithful, under the appearances of bread and wine.
Various Ways in Which Christ is Present
35All of us realize that there is more than one way in which Christ is present in His Church. We want to go into this very joyful subject, which the Constitution on the Sacred Liturgy presented briefly, (30) at somewhat greater length. Christ is present in His Church when she prays, since He is the one who "prays for us and prays in us and to whom we pray: He prays for us as our priest, He prays in us as our head, He is prayed to by us as our God" (31); and He is the one who has promised, "Where two or three are gathered together in my name, I am there in the midst of them." (32) He is present in the Church as she performs her works of mercy, not just because whatever good we do to one of His least brethren we do to Christ Himself, (33) but also because Christ is the one who performs these works through the Church and who continually helps men with His divine love. He is present in the Church as she moves along on her pilgrimage with a longing to reach the portals of eternal life, for He is the one who dwells in our hearts through faith, (34) and who instills charity in them through the Holy Spirit whom He gives to us. (35)
36In still another very genuine way, He is present in the Church as she preaches, since the Gospel which she proclaims is the word of God, and it is only in the name of Christ, the Incarnate Word of God, and by His authority and with His help that it is preached, so that there might be "one flock resting secure in one shepherd." (36)
37He is present in His Church as she rules and governs the People of God, since her sacred power comes from Christ and since Christ, the "Shepherd of Shepherds," (37) is present in the bishops who exercise that power, in keeping with the promise He made to the Apostles.
38Moreover, Christ is present in His Church in a still more sublime manner as she offers the Sacrifice of the Mass in His name; He is present in her as she administers the sacraments. On the matter of Christ's presence in the offering of the Sacrifice of the Mass, We would like very much to call to mind what St. John Chrysostom, overcome with awe, had to say in such accurate and eloquent words: "I wish to add something that is clearly awe-inspiring, but do not be surprised or upset. What is this? It is the same offering, no matter who offers it, be it Peter or Paul. It is the same one that Christ gave to His disciples and the same one that priests now perform: the latter is in no way inferior to the former, for it is not men who sanctify the latter, but He who sanctified the former. For just as the words which God spoke are the same as those that the priest now pronounces, so too the offering is the same." (38) No one is unaware that the sacraments are the actions of Christ who administers them through men. And so the sacraments are holy in themselves and they pour grace into the soul by the power of Christ, when they touch the body.
The Highest Kind of Presence
These various ways in which Christ is present fill the mind with astonishment and offer the Church a mystery for her contemplation. But there is another way in which Christ is present in His Church, a way that surpasses all the others. It is His presence in the Sacrament of the Eucharist, which is, for this reason, "a more consoling source of devotion, a lovelier object of contemplation and holier in what it contains" (39) than all the other sacraments; for it contains Christ Himself and it is "a kind of consummation of the spiritual life, and in a sense the goal of all the sacraments." (40)
39This presence is called "real" not to exclude the idea that the others are "real" too, but rather to indicate presence par excellence, because it is substantial and through it Christ becomes present whole and entire, God and man. (41) And so it would be wrong for anyone to try to explain this manner of presence by dreaming up a so-called "pneumatic" nature of the glorious body of Christ that would be present everywhere; or for anyone to limit it to symbolism, as if this most sacred Sacrament were to consist in nothing more than an efficacious sign "of the spiritual presence of Christ and of His intimate union with the faithful, the members of His Mystical Body." (42)
The Proper Use of Symbolism
40It is true that the Fathers and Scholastics had a great deal to say about symbolism in the Eucharist, especially with regard to the unity of the Church. The Council of Trent, in re-stating their doctrine, taught that our Saviour bequeathed the Eucharist to His Church "as a symbol . . . of the unity and charity with which He wished all Christians to be joined among themselves," "and hence as a symbol of that one Body of which He is the Head." (43)
41When Christian literature was still in its infancy, the unknown author of the work called the "Didache or Teaching of the Twelve Apostles" had this to write on the subject: "As far as the Eucharist is concerned, give thanks in this manner: . . . just as this bread had been broken and scattered over the hills and was made one when it was gathered together, so too may your church be gathered into your kingdom from the ends of the earth." (44)
42St. Cyprian too, in the course of laying stress on the Church's unity in opposition to schism, said this: "Finally the Lord's sacrifices proclaim the unity of Christians who are bound together by a firm and unshakeable charity. For when the Lord calls the bread that has been made from many grains of wheat His Body, He is describing our people whose unity He has sustained; and when He refers to wine pressed from many grapes and berries as His Blood, once again He is speaking of our flock which has been formed by fusing many into one." (45)
43But before all of these, St. Paul had written to the Corinthians: "The one bread makes us one body, though we are many in number; the same bread is shared by all." (46)
Symbolism Inadequate to Express Real Presence
44While Eucharistic symbolism is well suited to helping us understand the effect that is proper to this Sacrament—the unity of the Mystical Body—still it does not indicate or explain what it is that makes this Sacrament different from all the others. For the constant teaching that the Catholic Church has passed on to her catechumens, the understanding of the Christian people, the doctrine defined by the Council of Trent, the very words that Christ used when He instituted the Most Holy Eucharist, all require us to profess that "the Eucharist is the flesh of Our Savior Jesus Christ which suffered for our sins and which the Father in His loving kindness raised again." (47) To these words of St. Ignatius, we may well add those which Theodore of Mopsuestia, who is a faithful witness to the faith of the Church on this point, addressed to the people: "The Lord did not say: This is a symbol of my body, and this is a symbol of my blood, but rather: This is my body and my blood. He teaches us not to look to the nature of what lies before us and is perceived by the senses, because the giving of thanks and the words spoken over it have changed it into flesh and blood." (48)
45The Council of Trent, basing itself on this faith of the Church, "openly and sincerely professes that after the consecration of the bread and wine, Our Lord Jesus Christ, true God and man, is really, truly and substantially contained in the Blessed Sacrament of the Holy Eucharist under the outward appearances of sensible things." And so Our Savior is present in His humanity not only in His natural manner of existence at the right hand of the Father, but also at the same time in the sacrament of the Eucharist "in a manner of existing that we can hardly express in words but that our minds, illumined by faith, can come to see as possible to God and that we must most firmly believe." (49)
