Catholic Q/A Eucharist - Del

From Del April 2, 2009 The Catholic Eucharist - Q/A from Catholics

There are many questions about the Catholic Eucharist. Catholics

believe that Christ is truly with them in the body of the Priest, so

to speak.

I took this paragraph out from below:

What does it mean that Jesus Christ is present in the Eucharist under

the appearances of bread and wine? How does this happen? The presence

of the risen Christ in the Eucharist is an inexhaustible mystery that

the Church can never fully explain in words. We must remember that the

TRIUNE GOD is the creator of all that exists and has the power to do

more than we can possibly imagine. As St. Ambrose said: "If the word

of the Lord Jesus is so powerful as to bring into existence things

which were not, then a fortiori those things which already exist can

be changed into something else"

You might find the following interesting.

Introduction

The Lord Jesus, on the night before he suffered on the cross, shared

one last meal with his disciples. During this meal our Savior

instituted the sacrament of his Body and Blood. He did this in order

to perpetuate the sacrifice of the Cross throughout the ages and to

entrust to the Church his Spouse a memorial of his death and

resurrection. As the Gospel of Matthew tells us:

While they were eating, Jesus took bread, said the blessing, broke

it, and giving it to his disciples said, "Take and eat; this is my

body." Then he took a cup, gave thanks, and gave it to them, saying,

"Drink from it, all of you, for this is my blood of the covenant,

which will be shed on behalf of many for the forgiveness of sins." (Mt

26:26-28; cf. Mk 14:22-24, Lk 22:17-20, 1 Cor 11:23-25)

Recalling these words of Jesus, the Catholic Church professes that, in

the celebration of the Eucharist, bread and wine become the Body and

Blood of Jesus Christ through the power of the Holy Spirit and the

instrumentality of the priest. Jesus said: "I am the living bread that

came down from heaven; whoever eats this bread will live forever; and

the bread that I will give is my flesh for the life of the world. . .

. For my flesh is true food, and my blood is true drink" (Jn 6:51-55).

The whole Christ is truly present, body, blood, soul, and divinity,

under the appearances of bread and wine—the glorified Christ who rose

from the dead after dying for our sins. This is what the Church means

when she speaks of the "Real Presence" of Christ in the Eucharist.

This presence of Christ in the Eucharist is called "real" not to

exclude other types of his presence as if they could not be understood

as real (cf. Catechism, no. 1374). The risen Christ is present to his

Church in many ways, but most especially through the sacrament of his

Body and Blood.

What does it mean that Jesus Christ is present in the Eucharist under

the appearances of bread and wine? How does this happen? The presence

of the risen Christ in the Eucharist is an inexhaustible mystery that

the Church can never fully explain in words. We must remember that the

triune God is the creator of all that exists and has the power to do

more than we can possibly imagine. As St. Ambrose said: "If the word

of the Lord Jesus is so powerful as to bring into existence things

which were not, then a fortiori those things which already exist can

be changed into something else" (De Sacramentis, IV, 5-16). God

created the world in order to share his life with persons who are not

God. This great plan of salvation reveals a wisdom that surpasses our

understanding. But we are not left in ignorance: for out of his love

for us, God reveals his truth to us in ways that we can understand

through the gift of faith and the grace of the Holy Spirit dwelling in

us. We are thus enabled to understand at least in some measure what

would otherwise remain unknown to us, though we can never completely

comprehend the mystery of God.

As successors of the Apostles and teachers of the Church, the bishops

have the duty to hand on what God has revealed to us and to encourage

all members of the Church to deepen their understanding of the mystery

and gift of the Eucharist. In order to foster such a deepening of

faith, we have prepared this text to respond to fifteen questions that

commonly arise with regard to the Real Presence of Christ in the

Eucharist. We offer this text to pastors and religious educators to

assist them in their teaching responsibilities. We recognize that some

of these questions involve rather complex theological ideas. It is our

hope, however, that study and discussion of the text will aid many of

the Catholic faithful in our country to enrich their understanding of

this mystery of the faith.

1. Why does Jesus give himself to us as food and drink?

Jesus gives himself to us in the Eucharist as spiritual

nourishment because he loves us. God's whole plan for our salvation is

directed to our participation in the life of the Trinity, the

communion of Father, Son, and Holy Spirit. Our sharing in this life

begins with our Baptism, when by the power of the Holy Spirit we are

joined to Christ, thus becoming adopted sons and daughters of the

Father. It is strengthened and increased in Confirmation. It is

nourished and deepened through our participation in the Eucharist. By

eating the Body and drinking the Blood of Christ in the Eucharist we

become united to the person of Christ through his humanity. "Whoever

eats my flesh and drinks my blood remains in me and I in him" (Jn

6:56). In being united to the humanity of Christ we are at the same

time united to his divinity. Our mortal and corruptible natures are

transformed by being joined to the source of life. "Just as the living

Father sent me and I have life because of the Father, so also the one

who feeds on me will have life because of me" (Jn 6:57).

By being united to Christ through the power of the Holy Spirit

dwelling in us, we are drawn up into the eternal relationship of love

among the Father, the Son, and the Holy Spirit. As Jesus is the

eternal Son of God by nature, so we become sons and daughters of God

by adoption through the sacrament of Baptism. Through the sacraments

of Baptism and Confirmation (Chrismation), we are temples of the Holy

Spirit, who dwells in us, and by his indwelling we are made holy by

the gift of sanctifying grace. The ultimate promise of the Gospel is

that we will share in the life of the Holy Trinity. The Fathers of the

Church called this participation in the divine life "divinization"

(theosis). In this we see that God does not merely send us good things

from on high; instead, we are brought up into the inner life of God,

the communion among the Father, the Son, and the Holy Spirit. In the

celebration of the Eucharist (which means "thanksgiving") we give

praise and glory to God for this sublime gift.

2. Why is the Eucharist not only a meal but also a sacrifice?

While our sins would have made it impossible for us to share in

the life of God, Jesus Christ was sent to remove this obstacle. His

death was a sacrifice for our sins. Christ is "the Lamb of God, who

takes away the sin of the world" (Jn 1:29). Through his death and

resurrection, he conquered sin and death and reconciled us to God. The

Eucharist is the memorial of this sacrifice. The Church gathers to

remember and to re-present the sacrifice of Christ in which we share

through the action of the priest and the power of the Holy Spirit.

Through the celebration of the Eucharist, we are joined to Christ's

sacrifice and receive its inexhaustible benefits.

As the Letter to the Hebrews explains, Jesus is the one eternal

high priest who always lives to make intercession for the people

before the Father. In this way, he surpasses the many high priests who

over centuries used to offer sacrifices for sin in the Jerusalem

temple. The eternal high priest Jesus offers the perfect sacrifice

which is his very self, not something else. "He entered once for all

into the sanctuary, not with the blood of goats and calves but with

his own blood, thus obtaining eternal redemption" (Heb 9:12).

Jesus' act belongs to human history, for he is truly human and

has entered into history. At the same time, however, Jesus Christ is

the Second Person of the Holy Trinity; he is the eternal Son, who is

not confined within time or history. His actions transcend time, which

is part of creation. "Passing through the greater and more perfect

tabernacle not made by hands, that is, not belonging to this creation"

(Heb 9:11), Jesus the eternal Son of God made his act of sacrifice in

the presence of his Father, who lives in eternity. Jesus' one perfect

sacrifice is thus eternally present before the Father, who eternally

accepts it. This means that in the Eucharist, Jesus does not sacrifice

himself again and again. Rather, by the power of the Holy Spirit his

one eternal sacrifice is made present once again, re-presented, so

that we may share in it.

Christ does not have to leave where he is in heaven to be with

us. Rather, we partake of the heavenly liturgy where Christ eternally

intercedes for us and presents his sacrifice to the Father and where

the angels and saints constantly glorify God and give thanks for all

his gifts: "To the one who sits on the throne and to the Lamb be

blessing and honor, glory and might, forever and ever" (Rev 5:13). As

the Catechism of the Catholic Church states, "By the Eucharistic

celebration we already unite ourselves with the heavenly liturgy and

anticipate eternal life, when God will be all in all" (no. 1326). The

Sanctus proclamation, "Holy, Holy, Holy Lord . . . ," is the song of

the angels who are in the presence of God (Is 6:3). When in the

Eucharist we proclaim the Sanctus we echo on earth the song of angels

as they worship God in heaven. In the eucharistic celebration we do

not simply remember an event in history. Rather, through the

mysterious action of the Holy Spirit in the eucharistic celebration

the Lord's Paschal Mystery is made present and contemporaneous to his

Spouse the Church.

Furthermore, in the eucharistic re-presentation of Christ's

eternal sacrifice before the Father, we are not simply spectators. The

priest and the worshiping community are in different ways active in

the eucharistic sacrifice. The ordained priest standing at the altar

represents Christ as head of the Church. All the baptized, as members

of Christ's Body, share in his priesthood, as both priest and victim.

The Eucharist is also the sacrifice of the Church. The Church, which

is the Body and Bride of Christ, participates in the sacrificial

offering of her Head and Spouse. In the Eucharist, the sacrifice of

Christ becomes the sacrifice of the members of his Body who united to

Christ form one sacrificial offering (cf. Catechism, no. 1368). As

Christ's sacrifice is made sacramentally present, united with Christ,

we offer ourselves as a sacrifice to the Father. "The whole Church

exercises the role of priest and victim along with Christ, offering

the Sacrifice of the Mass and itself completely offered in it"

(Mysterium Fidei, no. 31; cf. Lumen Gentium, no. 11).

3. When the bread and wine become the Body and Blood of Christ, why

do they still look and taste like bread and wine?

In the celebration of the Eucharist, the glorified Christ

becomes present under the appearances of bread and wine in a way that

is unique, a way that is uniquely suited to the Eucharist. In the

Church's traditional theological language, in the act of consecration

during the Eucharist the "substance" of the bread and wine is changed

by the power of the Holy Spirit into the "substance" of the Body and

Blood of Jesus Christ. At the same time, the "accidents" or

appearances of bread and wine remain. "Substance" and "accident" are

here used as philosophical terms that have been adapted by great

medieval theologians such as St. Thomas Aquinas in their efforts to

understand and explain the faith. Such terms are used to convey the

fact that what appears to be bread and wine in every way (at the level

of "accidents" or physical attributes - that is, what can be seen,

touched, tasted, or measured) in fact is now the Body and Blood of

Christ (at the level of "substance" or deepest reality). This change

at the level of substance from bread and wine into the Body and Blood

of Christ is called "transubstantiation." According to Catholic faith,

we can speak of the Real Presence of Christ in the Eucharist because

this transubstantiation has occurred (cf. Catechism, no. 1376).

This is a great mystery of our faith—we can only know it from

Christ's teaching given us in the Scriptures and in the Tradition of

the Church. Every other change that occurs in the world involves a

change in accidents or characteristics. Sometimes the accidents change

while the substance remains the same. For example, when a child

reaches adulthood, the characteristics of the human person change in

many ways, but the adult remains the same person—the same substance.

At other times, the substance and the accidents both change. For

example, when a person eats an apple, the apple is incorporated into

the body of that person—is changed into the body of that person. When

this change of substance occurs, however, the accidents or

characteristics of the apple do not remain. As the apple is changed

into the body of the person, it takes on the accidents or

characteristics of the body of that person. Christ's presence in the

Eucharist is unique in that, even though the consecrated bread and

wine truly are in substance the Body and Blood of Christ, they have

none of the accidents or characteristics of a human body, but only

those of bread and wine.

4. Does the bread cease to be bread and the wine cease to be wine?

Yes. In order for the whole Christ to be present—body, blood,

soul, and divinity—the bread and wine cannot remain, but must give way

so that his glorified Body and Blood may be present. Thus in the

Eucharist the bread ceases to be bread in substance, and becomes the

Body of Christ, while the wine ceases to be wine in substance, and

becomes the Blood of Christ. As St. Thomas Aquinas observed, Christ is

not quoted as saying, "This bread is my body," but "This is my body"

(Summa Theologiae, III q. 78, a. 5).

5. Is it fitting that Christ's Body and Blood become present in the

Eucharist under the appearances of bread and wine?

Yes, for this way of being present corresponds perfectly to the

sacramental celebration of the Eucharist. Jesus Christ gives himself

to us in a form that employs the symbolism inherent in eating bread

and drinking wine. Furthermore, being present under the appearances of

bread and wine, Christ gives himself to us in a form that is

appropriate for human eating and drinking. Also, this kind of presence

corresponds to the virtue of faith, for the presence of the Body and

Blood of Christ cannot be detected or discerned by any way other than

faith. That is why St. Bonaventure affirmed: "There is no difficulty

over Christ's being present in the sacrament as in a sign; the great

difficulty is in the fact that He is really in the sacrament, as He is

in heaven. And so believing this is especially meritorious" (In IV

Sent., dist. X, P. I, art. un., qu. I). On the authority of God who

reveals himself to us, by faith we believe that which cannot be

grasped by our human faculties (cf. Catechism, no. 1381).

6. Are the consecrated bread and wine "merely symbols"?

In everyday language, we call a "symbol" something that points

beyond itself to something else, often to several other realities at

once. The transformed bread and wine that are the Body and Blood of

Christ are not merely symbols because they truly are the Body and

Blood of Christ. As St. John Damascene wrote: "The bread and wine are

not a foreshadowing of the body and blood of Christ—By no means!—but

the actual deified body of the Lord, because the Lord Himself said:

‘This is my body'; not ‘a foreshadowing of my body' but ‘my body,' and

not ‘a foreshadowing of my blood' but ‘my blood'" (The Orthodox Faith,

IV [PG 94, 1148-49]).

At the same time, however, it is important to recognize that the

Body and Blood of Christ come to us in the Eucharist in a sacramental

form. In other words, Christ is present under the appearances of bread

and wine, not in his own proper form. We cannot presume to know all

the reasons behind God's actions. God uses, however, the symbolism

inherent in the eating of bread and the drinking of wine at the

natural level to illuminate the meaning of what is being accomplished

in the Eucharist through Jesus Christ.

There are various ways in which the symbolism of eating bread

and drinking wine discloses the meaning of the Eucharist. For example,

just as natural food gives nourishment to the body, so the eucharistic

food gives spiritual nourishment. Furthermore, the sharing of an

ordinary meal establishes a certain communion among the people who

share it; in the Eucharist, the People of God share a meal that brings

them into communion not only with each other but with the Father, Son,

and Holy Spirit. Similarly, as St. Paul tells us, the single loaf that

is shared among many during the eucharistic meal is an indication of

the unity of those who have been called together by the Holy Spirit as

one body, the Body of Christ (1 Cor 10:17). To take another example,

the individual grains of wheat and individual grapes have to be

harvested and to undergo a process of grinding or crushing before they

are unified as bread and as wine. Because of this, bread and wine

point to both the union of the many that takes place in the Body of

Christ and the suffering undergone by Christ, a suffering that must

also be embraced by his disciples. Much more could be said about the

many ways in which the eating of bread and drinking of wine symbolize

what God does for us through Christ, since symbols carry multiple

meanings and connotations.

7. Do the consecrated bread and wine cease to be the Body and Blood

of Christ when the Mass is over?

No. During the celebration of the Eucharist, the bread and wine

become the Body and Blood of Christ, and this they remain. They cannot

turn back into bread and wine, for they are no longer bread and wine

at all. There is thus no reason for them to change back to their

"normal" state after the special circumstances of the Mass are past.

Once the substance has really changed, the presence of the Body and

Blood of Christ "endures as long as the Eucharistic species subsist"

(Catechism, no. 1377). Against those who maintained that the bread

that is consecrated during the Eucharist has no sanctifying power if

it is left over until the next day, St. Cyril of Alexandria replied,

"Christ is not altered, nor is his holy body changed, but the power of

the consecration and his life-giving grace is perpetual in it" (Letter

83, to Calosyrius, Bishop of Arsinoe [PG 76, 1076]). The Church

teaches that Christ remains present under the appearances of bread and

wine as long as the appearances of bread and wine remain (cf.

Catechism, no. 1377).

8. Why are some of the consecrated hosts reserved after the Mass?

While it would be possible to eat all of the bread that is

consecrated during the Mass, some is usually kept in the tabernacle.

The Body of Christ under the appearance of bread that is kept or

"reserved" after the Mass is commonly referred to as the "Blessed

Sacrament." There are several pastoral reasons for reserving the

Blessed Sacrament. First of all, it is used for distribution to the

dying (Viaticum), the sick, and those who legitimately cannot be

present for the celebration of the Eucharist. Secondly, the Body of

Christ in the form of bread is to be adored when it is exposed, as in

the Rite of Eucharistic Exposition and Benediction, when it is carried

in eucharistic processions, or when it is simply placed in the

tabernacle, before which people pray privately. These devotions are

based on the fact that Christ himself is present under the appearance

of bread. Many holy people well known to American Catholics, such as

St. John Neumann, St. Elizabeth Ann Seton, St. Katharine Drexel, and

Blessed Damien of Molokai, practiced great personal devotion to Christ

present in the Blessed Sacrament. In the Eastern Catholic Churches,

devotion to the reserved Blessed Sacrament is practiced most directly

at the Divine Liturgy of the Presanctified Gifts, offered on weekdays

of Lent.

9. What are appropriate signs of reverence with respect to the Body

and Blood of Christ?

The Body and Blood of Christ present under the appearances of

bread and wine are treated with the greatest reverence both during and

after the celebration of the Eucharist (cf. Mysterium Fidei, nos.

56-61). For example, the tabernacle in which the consecrated bread is

reserved is placed "in some part of the church or oratory which is

distinguished, conspicuous, beautifully decorated, and suitable for

prayer" (Code of Canon Law, Can. 938, §2). According to the tradition

of the Latin Church, one should genuflect in the presence of the

tabernacle containing the reserved sacrament. In the Eastern Catholic

Churches, the traditional practice is to make the sign of the cross

and to bow profoundly. The liturgical gestures from both traditions

reflect reverence, respect, and adoration. It is appropriate for the

members of the assembly to greet each other in the gathering space of

the church (that is, the vestibule or narthex), but it is not

appropriate to speak in loud or boisterous tones in the body of the

church (that is, the nave) because of the presence of Christ in the

tabernacle. Also, the Church requires everyone to fast before

receiving the Body and Blood of Christ as a sign of reverence and

recollection (unless illness prevents one from doing so). In the Latin

Church, one must generally fast for at least one hour; members of

Eastern Catholic Churches must follow the practice established by

their own Church.

10. If someone without faith eats and drinks the consecrated bread

and wine, does he or she still receive the Body and Blood of Christ?

If "to receive" means "to consume," the answer is yes, for what

the person consumes is the Body and Blood of Christ. If "to receive"

means "to accept the Body and Blood of Christ knowingly and willingly

as what they are, so as to obtain the spiritual benefit," then the

answer is no. A lack of faith on the part of the person eating and

drinking the Body and Blood of Christ cannot change what these are,

but it does prevent the person from obtaining the spiritual benefit,

which is communion with Christ. Such reception of Christ's Body and

Blood would be in vain and, if done knowingly, would be sacrilegious

(1 Cor 11:29). Reception of the Blessed Sacrament is not an automatic

remedy. If we do not desire communion with Christ, God does not force

this upon us. Rather, we must by faith accept God's offer of communion

in Christ and in the Holy Spirit, and cooperate with God's grace in

order to have our hearts and minds transformed and our faith and love

of God increased.

11. If a believer who is conscious of having committed a mortal sin

eats and drinks the consecrated bread and wine, does he or she still

receive the Body and Blood of Christ?

Yes. The attitude or disposition of the recipient cannot change

what the consecrated bread and wine are. The question here is thus not

primarily about the nature of the Real Presence, but about how sin

affects the relationship between an individual and the Lord. Before

one steps forward to receive the Body and Blood of Christ in Holy

Communion, one needs to be in a right relationship with the Lord and

his Mystical Body, the Church - that is, in a state of grace, free of

all mortal sin. While sin damages, and can even destroy, that

relationship, the sacrament of Penance can restore it. St. Paul tells

us that "whoever eats the bread or drinks the cup of the Lord

unworthily will have to answer for the body and blood of the Lord. A

person should examine himself, and so eat the bread and drink the cup"

(1 Cor 11:27-28). Anyone who is conscious of having committed a mortal

sin should be reconciled through the sacrament of Penance before

receiving the Body and Blood of Christ, unless a grave reason exists

for doing so and there is no opportunity for confession. In this case,

the person is to be mindful of the obligation to make an act of

perfect contrition, that is, an act of sorrow for sins that "arises

from a love by which God is loved above all else" (Catechism, no.

1452). The act of perfect contrition must be accompanied by the firm

intention of making a sacramental confession as soon as possible.

12. Does one receive the whole Christ if one receives Holy Communion

under a single form?

Yes. Christ Jesus, our Lord and Savior, is wholly present under

the appearance either of bread or of wine in the Eucharist.

Furthermore, Christ is wholly present in any fragment of the

consecrated Host or in any drop of the Precious Blood. Nevertheless,

it is especially fitting to receive Christ in both forms during the

celebration of the Eucharist. This allows the Eucharist to appear more

perfectly as a banquet, a banquet that is a foretaste of the banquet

that will be celebrated with Christ at the end of time when the

Kingdom of God is established in its fullness (cf. Eucharisticum

Mysterium, no. 32).

13. Is Christ present during the celebration of the Eucharist in

other ways in addition to his Real Presence in the Blessed Sacrament?

Yes. Christ is present during the Eucharist in various ways. He

is present in the person of the priest who offers the sacrifice of the

Mass. According to the Constitution on the Sacred Liturgy of the

Second Vatican Council, Christ is present in his Word "since it is he

himself who speaks when the holy scriptures are read in the Church."

He is also present in the assembled people as they pray and sing, "for

he has promised ‘where two or three are gathered together in my name

there am I in the midst of them' (Mt 18:20)" (Sacrosanctum Concilium,

no. 7). Furthermore, he is likewise present in other sacraments; for

example, "when anybody baptizes it is really Christ himself who

baptizes" (ibid.).

We speak of the presence of Christ under the appearances of

bread and wine as "real" in order to emphasize the special nature of

that presence. What appears to be bread and wine is in its very

substance the Body and Blood of Christ. The entire Christ is present,

God and man, body and blood, soul and divinity. While the other ways

in which Christ is present in the celebration of the Eucharist are

certainly not unreal, this way surpasses the others. "This 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" (Mysterium Fidei, no. 39).

14. Why do we speak of the "Body of Christ" in more than one sense?

First, the Body of Christ refers to the human body of Jesus

Christ, who is the divine Word become man. During the Eucharist, the

bread and wine become the Body and Blood of Christ. As human, Jesus

Christ has a human body, a resurrected and glorified body that in the

Eucharist is offered to us in the form of bread and wine.

Secondly, as St. Paul taught us in his letters, using the

analogy of the human body, the Church is the Body of Christ, in which

many members are united with Christ their head (1 Cor 10:16-17,

12:12-31; Rom 12:4-8). This reality is frequently referred to as the

Mystical Body of Christ. All those united to Christ, the living and

the dead, are joined together as one Body in Christ. This union is not

one that can be seen by human eyes, for it is a mystical union brought

about by the power of the Holy Spirit.

The Mystical Body of Christ and the eucharistic Body of Christ

are inseparably linked. By Baptism we enter the Mystical Body of

Christ, the Church, and by receiving the eucharistic Body of Christ we

are strengthened and built up into the Mystical Body of Christ. The

central act of the Church is the celebration of the Eucharist; the

individual believers are sustained as members of the Church, members

of the Mystical Body of Christ, through their reception of the Body of

Christ in the Eucharist. Playing on the two meanings of "Body of

Christ," St. Augustine tells those who are to receive the Body of

Christ in the Eucharist: "Be what you see, and receive what you are"

(Sermon 272). In another sermon he says, "If you receive worthily, you

are what you have received" (Sermon 227).

The work of the Holy Spirit in the celebration of the Eucharist

is twofold in a way that corresponds to the twofold meaning of "Body

of Christ." On the one hand, it is through the power of the Holy

Spirit that the risen Christ and his act of sacrifice become present.

In the eucharistic prayer, the priest asks the Father to send the Holy

Spirit down upon the gifts of bread and wine to transform them into

the Body and Blood of Christ (a prayer known as the epiclesis or

"invocation upon"). On the other hand, at the same time the priest

also asks the Father to send the Holy Spirit down upon the whole

assembly so that "those who take part in the Eucharist may be one body

and one spirit" (Catechism, no. 1353). It is through the Holy Spirit

that the gift of the eucharistic Body of Christ comes to us and

through the Holy Spirit that we are joined to Christ and each other as

the Mystical Body of Christ.

By this we can see that the celebration of the Eucharist does

not just unite us to God as individuals who are isolated from one

another. Rather, we are united to Christ together with all the other

members of the Mystical Body. The celebration of the Eucharist should

thus increase our love for one another and remind us of our

responsibilities toward one another. Furthermore, as members of the

Mystical Body, we have a duty to represent Christ and to bring Christ

to the world. We have a responsibility to share the Good News of

Christ not only by our words but also by how we live our lives. We

also have a responsibility to work against all the forces in our world

that oppose the Gospel, including all forms of injustice. The

Catechism of the Catholic Church teaches us: "The Eucharist commits us

to the poor. To receive in truth the Body and Blood of Christ given up

for us, we must recognize Christ in the poorest, his brethren" (no.

1397).

15. Why do we call the presence of Christ in the Eucharist a "mystery"?

The word "mystery" is commonly used to refer to something that

escapes the full comprehension of the human mind. In the Bible,

however, the word has a deeper and more specific meaning, for it

refers to aspects of God's plan of salvation for humanity, which has

already begun but will be completed only with the end of time. In

ancient Israel, through the Holy Spirit God revealed to the prophets

some of the secrets of what he was going to accomplish for the

salvation of his people (cf. Am 3:7; Is 21:28; Dan 2:27-45). Likewise,

through the preaching and teaching of Jesus, the mystery of "the

Kingdom of God" was being revealed to his disciples (Mk 4:11-12). St.

Paul explained that the mysteries of God may challenge our human

understanding or may even seem to be foolishness, but their meaning is

revealed to the People of God through Jesus Christ and the Holy Spirit

(cf. 1 Cor 1:18-25, 2:6-10; Rom 16:25-27; Rev 10:7).

The Eucharist is a mystery because it participates in the

mystery of Jesus Christ and God's plan to save humanity through

Christ. We should not be surprised if there are aspects of the

Eucharist that are not easy to understand, for God's plan for the

world has repeatedly surpassed human expectations and human

understanding (cf. Jn 6:60-66). For example, even the disciples did

not at first understand that it was necessary for the Messiah to be

put to death and then to rise from the dead (cf. Mk 8:31-33, 9:31-32,

10:32-34; Mt 16: 21-23, 17:22-23, 20:17-19; Lk 9:22, 9:43-45,

18:31-34). Furthermore, any time that we are speaking of God we need

to keep in mind that our human concepts never entirely grasp God. We

must not try to limit God to our understanding, but allow our

understanding to be stretched beyond its normal limitations by God's

revelation.

Conclusion

By his Real Presence in the Eucharist Christ fulfils his promise to be

with us "always, until the end of the age" (Mt 28:20). As St. Thomas

Aquinas wrote, "It is the law of friendship that friends should live

together. . . . Christ has not left us without his bodily presence in

this our pilgrimage, but he joins us to himself in this sacrament in

the reality of his body and blood" (Summa Theologiae, III q. 75, a.

1). With this gift of Christ's presence in our midst, the Church is

truly blessed. As Jesus told his disciples, referring to his presence

among them, "Amen, I say to you, many prophets and righteous people

longed to see what you see but did not see it, and to hear what you

hear but did not hear it" (Mt 13:17). In the Eucharist the Church both

receives the gift of Jesus Christ and gives grateful thanks to God for

such a blessing. This thanksgiving is the only proper response, for

through this gift of himself in the celebration of the Eucharist under

the appearances of bread and wine Christ gives us the gift of eternal

life.

Amen, amen, I say to you, unless you eat the flesh of the Son of

Man and drink his blood, you do not have life within you. Whoever eats

my flesh and drinks my blood has eternal life, and I will raise him on

the last day. For my flesh is true food, and my blood is true drink. .

. . Just as the living Father sent me and I have life because of the

Father, so also the one who feeds on me will have life because of me.

(Jn 6:53-57)
