Sacramentum Caritatis - Part 73 - Pope Benedict XVI

Living the Sunday obligation

73. Conscious of this new vital principle which the Eucharist imparts to the Christian, the Synod Fathers reaffirmed the importance of the Sunday obligation for all the faithful, viewing it as a wellspring of authentic freedom enabling them to live each day in accordance with what they celebrated on "the Lord's Day." The life of faith is endangered when we lose the desire to share in the celebration of the Eucharist and its commemoration of the paschal victory. Participating in the Sunday liturgical assembly with all our brothers and sisters, with whom we form one body in Jesus Christ, is demanded by our Christian conscience and at the same time it forms that conscience. 

To lose a sense of Sunday as the Lord's Day, a day to be sanctified, is symptomatic of the loss of an authentic sense of Christian freedom, the freedom of the children of God. (206) Here some observations made by my venerable predecessor John Paul II in his Apostolic Letter Dies Domini(207) continue to have great value. Speaking of the various dimensions of the Christian celebration of Sunday, he said that it is Dies Domini with regard to the work of creation, Dies Christi as the day of the new creation and the Risen Lord's gift of the Holy Spirit, Dies Ecclesiae as the day on which the Christian community gathers for the celebration, and Dies hominis as the day of joy, rest and fraternal charity.  Sunday thus appears as the primordial holy day, when all believers, wherever they are found, can become heralds and guardians of the true meaning of time. 

It gives rise to the Christian meaning of life and a new way of experiencing time, relationships, work, life and death. On the Lord's Day, then, it is fitting that Church groups should organize, around Sunday Mass, the activities of the Christian community: social gatherings, programmes for the faith formation of children, young people and adults, pilgrimages, charitable works, and different moments of prayer. For the sake of these important values – while recognizing that Saturday evening, beginning with First Vespers, is already a part of Sunday and a time when the Sunday obligation can be fulfilled – we need to remember that it is Sunday itself that is meant to be kept holy, lest it end up as a day "empty of God."

Sacramentum Caritatis - Parts 36 & 37. Pope Benedict XVI

The eucharistic celebration, the work of "Christus Totus"

Christus totus in capite et in corpore

36. The "subject" of the liturgy's intrinsic beauty is Christ himself, risen and glorified in the Holy Spirit, who includes the Church in his work. (109) Here we can recall an evocative phrase of Saint Augustine which strikingly describes this dynamic of faith proper to the Eucharist. The great Bishop of Hippo, speaking specifically of the eucharistic mystery, stresses the fact that Christ assimilates us to himself: "The bread you see on the altar, sanctified by the word of God, is the body of Christ. The chalice, or rather, what the chalice contains, sanctified by the word of God, is the blood of Christ. In these signs, Christ the Lord willed to entrust to us his body and the blood which he shed for the forgiveness of our sins. If you have received them properly, you yourselves are what you have received." (110) Consequently, "not only have we become Christians, we have become Christ himself." (111) We can thus contemplate God's mysterious work, which brings about a profound unity between ourselves and the Lord Jesus: "one should not believe that Christ is in the head but not in the body; rather he is complete in the head and in the body." (112)

The Eucharist and the risen Christ

37. Since the eucharistic liturgy is essentially an actio Dei which draws us into Christ through the Holy Spirit, its basic structure is not something within our power to change, nor can it be held hostage by the latest trends. Here too Saint Paul's irrefutable statement applies: "no one can lay any foundation other than the one that has been laid, which is Jesus Christ" (1 Cor 3:11). Again it is the Apostle of the Gentiles who assures us that, with regard to the Eucharist, he is presenting not his own teaching but what he himself has received (cf. 1 Cor 11:23). The celebration of the Eucharist implies and involves the living Tradition. The Church celebrates the eucharistic sacrifice in obedience to Christ's command, based on her experience of the Risen Lord and the outpouring of the Holy Spirit. For this reason, from the beginning, the Christian community has gathered for the fractio panis on the Lord's Day. Sunday, the day Christ rose from the dead, is also the first day of the week, the day which the Old Testament tradition saw as the beginning of God's work of creation. The day of creation has now become the day of the "new creation," the day of our liberation, when we commemorate Christ who died and rose again (113).

Encyclical Letter on the Holy Eucharist - Parts 41 & 42

41. The Eucharist's particular effectiveness in promoting communion is one of the reasons for the importance of Sunday Mass. I have already dwelt on this and on the other reasons which make Sunday Mass fundamental for the life of the Church and of individual believers in my Apostolic Letter on the sanctification of Sunday Dies Domini.⁸⁶ There I recalled that the faithful have the obligation to attend Mass, unless they are seriously impeded, and that Pastors have the corresponding duty to see that it is practical and possible for all to fulfil this precept.⁸⁷ More recently, in my Apostolic Letter Novo Millennio Ineunte, in setting forth the pastoral path which the Church must take at the beginning of the third millennium, I drew particular attention to the Sunday Eucharist, emphasizing its effectiveness for building communion. “It is” – I wrote – “the privileged place where communion is ceaselessly proclaimed and nurtured. Precisely through sharing in the Eucharist, the Lord's Day also becomes the Day of the Church, when she can effectively exercise her role as the sacrament of unity”.⁸⁸ 

42. The safeguarding and promotion of ecclesial communion is a task of each member of the faithful, who finds in the Eucharist, as the sacrament of the Church's unity, an area of special concern. More specifically, this task is the particular responsibility of the Church's Pastors, each according to his rank and ecclesiastical office. For this reason the Church has drawn up norms aimed both at fostering the frequent and fruitful access of the faithful to the Eucharistic table and at determining the objective conditions under which communion may not be given. The care shown in promoting the faithful observance of these norms becomes a practical means of showing love for the Eucharist and for the Church.
