The Eucharist and the Christian Life
From Pope Benedict XVI, Sacramentum caritatis
The all-encompassing effect of eucharistic worship
71. Christianity’s new worship includes and transfigures every aspect of life: “Whether you eat or drink, or whatever you do, do all to the glory of God” (1 Cor 10:31). Christians, in all their actions, are called to offer true worship to God. Here the intrinsically eucharistic nature of Christian life begins to take shape. The Eucharist, since it embraces the concrete, everyday existence of the believer, makes possible, day by day, the progressive transfiguration of all those called by grace to reflect the image of the Son of God (cf. Rom 8:29ff.). There is nothing authentically human – our thoughts and affections, our words and deeds – that does not find in the sacrament of the Eucharist the form it needs to be lived to the full. Here we can see the full human import of the radical newness brought by Christ in the Eucharist: the worship of God in our lives cannot be relegated to something private and individual, but tends by its nature to permeate every aspect of our existence. Worship pleasing to God thus becomes a new way of living our whole life, each particular moment of which is lifted up, since it is lived as part of a relationship with Christ and as an offering to God. The glory of God is the living man (cf. 1 Cor 10:31). And the life of man is the vision of God.
Iuxta dominicam viventes – living in accordance with the Lord’s Day
72. From the beginning Christians were clearly conscious of this radical newness which the Eucharist brings to human life. The faithful immediately perceived the profound influence of the eucharistic celebration on their manner of life. Saint Ignatius of Antioch expressed this truth when he called Christians “those who have attained a new hope,” and described them as “those living in accordance with the Lord’s Day” (iuxta dominicam viventes). This phrase of the great Antiochene martyr highlights the connection between the reality of the Eucharist and everyday Christian life. The Christians’ customary practice of gathering on the first day after the Sabbath to celebrate the resurrection of Christ – according to the account of Saint Justin Martyr – is also what defines the form of a life renewed by an encounter with Christ. Saint Ignatius’ phrase – “living in accordance with the Lord’s Day” – also emphasizes that this holy day becomes paradigmatic for every other day of the week. Indeed, it is defined by something more than the simple suspension of one’s ordinary activities, a sort of parenthesis in one’s usual daily rhythm. Christians have always experienced this day as the first day of the week, since it commemorates the radical newness brought by Christ. Sunday is thus the day when Christians rediscover the eucharistic form which their lives are meant to have. “Living in accordance with the Lord’s Day” means living in the awareness of the liberation brought by Christ and making our lives a constant self-offering to God, so that his victory may be fully revealed to all humanity through a profoundly renewed existence.
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.
The meaning of rest and of work
74. Finally, it is particularly urgent nowadays to remember that the day of the Lord is also a day of rest from work. […] Christians, not without reference to the meaning of the Sabbath in the Jewish tradition, have seen in the Lord’s Day a day of rest from their daily exertions. This is highly significant, for it relativizes work and directs it to the person: work is for man and not man for work. It is easy to see how this actually protects men and women, emancipating them from a possible form of enslavement. […] It is on the day consecrated to God that men and women come to understand the meaning of their lives and also of their work.
