Introduction

The Church draws her life from the Eucharist. (Editor's note: In Latin, “Ecclesia de Eucharistia”, hence the title of this encyclical letter.) This truth does not simply express a daily experience of faith, but recapitulates the heart of the mystery of the Church. In a variety of ways she joyfully experiences the constant fulfilment of the promise: “Lo, I am with you always, to the close of the age” (Mt 28:20), but in the Holy Eucharist, through the changing of bread and wine into the body and blood of the Lord, she rejoices in this presence with unique intensity. Ever since Pentecost, when the Church, the People of the New Covenant, began her pilgrim journey towards her heavenly homeland, the Divine Sacrament has continued to mark the passing of her days, filling them with confident hope.

The Second Vatican Council rightly proclaimed that the Eucharistic sacrifice is “the source and summit of the Christian life”. “For the most holy Eucharist contains the Church's entire spiritual wealth: Christ Himself, our passover and living bread. Through His own flesh, now made living and life-giving by the Holy Spirit, He offers life to men”. Consequently the gaze of the Church is constantly turned to her Lord, present in the Sacrament of the Altar, in which she discovers the full manifestation of His boundless love.

On March 23, 2000, Pope John Paul II celebrated Mass in the Upper Room of Jerusalem, the very place where the First Mass — the Last Supper — took place.

During the Great Jubilee of the Year 2000, I had an opportunity to celebrate the Eucharist in the Cenacle of Jerusalem where, according to tradition, it was first celebrated by Jesus Himself. The Upper Room was where this most holy Sacrament was instituted. It is there that Christ took bread, broke it and gave it to His disciples, saying: “Take this, all of you, and eat it: this is My body which will be given up for you” (cf. Mk 26:26; Lk 22:19; 1 Cor 11:24). Then He took the cup of wine and said to them: “Take this, all of you and drink from it: this is the cup of My blood, the blood of the new and everlasting covenant. It will be shed for you and for all, so that sins may be forgiven” (cf. Mt 14:24; Lk 22:20; 1 Cor 11:25). I am grateful to the Lord Jesus for allowing me to repeat in that same place, in obedience to His command: “Do this in memory of Me” (Lk 22:19), the words which He spoke two thousand years ago.

Did the Apostles who took part in the Last Supper understand the meaning of the words spoken by Christ? Perhaps not. Those words would only be fully clear at the end of the Triduum sacrum, the time from Thursday evening to Sunday morning. Those days embrace the mysterium paschale; they also embrace the mysterium eucharisticum.

The Church was born of the paschal mystery. For this very reason the Eucharist, which is in an outstanding way the sacrament of the paschal mystery, stands at the centre of the Church's life. This is already clear from the earliest images of the Church found in the Acts of the Apostles: “They devoted themselves to the Apostles' teaching and fellowship, to the breaking of bread and the prayers” (2:42). The “breaking of the bread” refers to the Eucharist. Two thousand years later, we continue to relive that primordial image of the Church. At every celebration of the Eucharist, we are spiritually brought back to the paschal Triduum: to the events of the evening of Holy Thursday, to the Last Supper and to what followed it. The institution of the Eucharist sacramentally anticipated the events which were about to take place, beginning with the agony in Gethsemane. (...)

“Mysterium fidei! — The Mystery of Faith!”. When the priest recites or chants these words, all present acclaim: “We announce Your death, O Lord, and we proclaim Your resurrection, until You come in glory”.

In these or similar words the Church, while pointing to Christ in the mystery of His passion, also reveals her own mystery: Ecclesia de Eucharistia. By the gift of the Holy Spirit at Pentecost the Church was born and set out upon the pathways of the world, yet a decisive moment in her taking shape was certainly the institution of the Eucharist in the Upper Room. Her foundation and wellspring is the whole Triduum paschale, but this is as it were gathered up, foreshadowed and “concentrated' for ever in the gift of the Eucharist. In this gift Jesus Christ entrusted to His Church the perennial making present of the paschal mystery. With it He brought about a mysterious “oneness in time” between that Triduum and the passage of the centuries.

The thought of this leads us to profound amazement and gratitude. In the paschal event and the Eucharist which makes it present throughout the centuries, there is a truly enormous “capacity” which embraces all of history as the recipient of the grace of the redemption. This amazement should always fill the Church assembled for the celebration of the Eucharist. But in a special way it should fill the minister of the Eucharist. For it is he who, by the authority given him in the sacrament of priestly ordination, effects the consecration. It is he who says with the power coming to him from Christ in the Upper Room: “This is My body which will be given up for you This is the cup of My blood, poured out for you...”. The priest says these words, or rather he puts his voice at the disposal of the One who spoke these words in the Upper Room and who desires that they should be repeated in every generation by all those who in the Church ministerially share in His priesthood.

To contemplate Christ

I would like to rekindle this Eucharistic “amazement” by the present Encyclical Letter, in continuity with the Jubilee heritage which I have left to the Church in the Apostolic Letter Novo Millennio Ineunte and its Marian crowning, Rosarium Virginis Mariae. To contemplate the face of Christ, and to contemplate it with Mary, is the “programme” which I have set before the Church at the dawn of the third millennium, summoning her to put out into the deep on the sea of history with the enthusiasm of the new evangelization.

To contemplate Christ involves being able to recognize Him wherever He manifests Himself, in His many forms of presence, but above all in the living sacrament of His body and His blood. The Church draws her life from Christ in the Eucharist; by Him she is fed and by Him she is enlightened. The Eucharist is both a mystery of faith and a “mystery of light”. Whenever the Church celebrates the Eucharist, the faithful can in some way relive the experience of the two disciples on the road to Emmaus: “their eyes were opened and they recognized Him” (Lk 24:31).

From the time I began my ministry as the Successor of Peter, I have always marked Holy Thursday, the day of the Eucharist and of the priesthood, by sending a letter to all the priests of the world. This year, the twenty-fifth of my Pontificate, I wish to involve the whole Church more fully in this Eucharistic reflection, also as a way of thanking the Lord for the gift of the Eucharist and the priesthood: “Gift and Mystery”. By proclaiming the Year of the Rosary, I wish to put this, my twenty-fifth anniversary, under the aegis of the contemplation of Christ at the school of Mary. Consequently, I cannot let this Holy Thursday 2003 pass without halting before the “Eucharistic face” of Christ and pointing out with new force to the Church the centrality of the Eucharist.

From it the Church draws her life. From this “living bread” she draws her nourishment. How could I not feel the need to urge everyone to experience it ever anew?

When I think of the Eucharist, and look at my life as a priest, as a Bishop and as the Successor of Peter, I naturally recall the many times and places in which I was able to celebrate it. I remember the parish church of Niegowiæ, where I had my first pastoral assignment, the collegiate church of Saint Florian in Krakow, Wawel Cathedral, Saint Peter's Basilica and so many basilicas and churches in Rome and throughout the world. I have been able to celebrate Holy Mass in chapels built along mountain paths, on lakeshores and seacoasts; I have celebrated it on altars built in stadiums and in city squares... This varied scenario of celebrations of the Eucharist has given me a powerful experience of its universal and, so to speak, cosmic character. Yes, cosmic!

Because even when it is celebrated on the humble altar of a country church, the Eucharist is always in some way celebrated on the altar of the world. It unites heaven and earth. It embraces and permeates all creation. The Son of God became man in order to restore all creation, in one supreme act of praise, to the One who made it from nothing. He, the Eternal High Priest who by the blood of His Cross entered the eternal sanctuary, thus gives back to the Creator and Father all creation redeemed. He does so through the priestly ministry of the Church, to the glory of the Most Holy Trinity. Truly this is the mysterium fidei which is accomplished in the Eucharist: the world which came forth from the hands of God the Creator now returns to Him redeemed by Christ.

The Eucharist, as Christ's saving presence in the community of the faithful and its spiritual food, is the most precious possession which the Church can have in her journey through history. This explains the lively concern which she has always shown for the Eucharistic mystery, a concern which finds authoritative expression in the work of the Councils and the Popes. How can we not admire the doctrinal expositions of the Decrees on the Most Holy Eucharist and on the Holy Sacrifice of the Mass promulgated by the Council of Trent? For centuries those Decrees guided theology and catechesis, and they are still a dogmatic reference-point for the continual renewal and growth of God's People in faith and in love for the Eucharist. In times closer to our own, three Encyclical Letters should be mentioned: the Encyclical Mirae Caritatis of Leo XIII (May 28, 1902), the Encyclical Mediator Dei of Pius XII (November 20, 1947) and the Encyclical Mysterium Fidei of Paul VI (September 3, 1965).

The Second Vatican Council, while not issuing a specific document on the Eucharistic mystery, considered its various aspects throughout its documents, especially the Dogmatic Constitution on the Church Lumen Gentium and the Constitution on the Sacred Liturgy Sacrosanctum Concilium.

I myself, in the first years of my apostolic ministry in the Chair of Peter, wrote the Apostolic Letter Dominicae Cenae (February 24, 1980), in which I discussed some aspects of the Eucharistic mystery and its importance for the life of those who are its ministers. Today I take up anew the thread of that argument, with even greater emotion and gratitude in my heart, echoing as it were the word of the Psalmist: “What shall I render to the Lord for all His bounty to me? I will lift up the cup of salvation and call on the name of the Lord” (Ps 116:12-13).

Lights and shadows

The Magisterium's commitment to proclaiming the Eucharistic mystery has been matched by interior growth within the Christian community. Certainly the liturgical reform inaugurated by the Council has greatly contributed to a more conscious, active and fruitful participation in the Holy Sacrifice of the Altar on the part of the faithful. In many places, adoration of the Blessed Sacrament is also an important daily practice, and becomes an inexhaustible source of holiness. The devout participation of the faithful in the Eucharistic procession on the Solemnity of the Body and Blood of Christ is a grace from the Lord which yearly brings joy to those who take part in it. Other positive signs of Eucharistic faith and love might also be mentioned.

Unfortunately, alongside these lights, there are also shadows. In some places, the practice of Eucharistic adoration has been almost completely abandoned. In various parts of the Church abuses have occurred, leading to confusion with regard to sound faith and Catholic doctrine concerning this wonderful sacrament. At times one encounters an extremely reductive understanding of the Eucharistic mystery. Stripped of its sacrificial meaning, it is celebrated as if it were simply a fraternal banquet.

Furthermore, the necessity of the ministerial priesthood, grounded in apostolic succession, is at times obscured, and the sacramental nature of the Eucharist is reduced to its mere effectiveness as a form of proclamation. This has led here and there to ecumenical initiatives which, albeit well-intentioned, indulge in Eucharistic practices contrary to the discipline by which the Church expresses her faith. How can we not express profound grief at all this? The Eucharist is too great a gift to tolerate ambiguity and depreciation.

It is my hope that the present Encyclical Letter will effectively help to banish the dark clouds of unacceptable doctrine and practice, so that the Eucharist will continue to shine forth in all its radiant mystery.
