Lift up Your Hearts: Liturgical Devotion
“The Christians’ customary practice of gathering on the first day … to celebrate the resurrection of Christ – according to the account of Saint Justin Martyr(205) – is also what defines the form of a life renewed by an encounter with Christ.”

“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…, 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’ [cf. St. Ignatius of Antioch] 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.”

  1. Sunday as the Lord’s Day is…
    “Dies Domini with regard to the work of creation” [the day the Lord rested after the six days of creation]
    “Dies Christi as the day of the new creation and the Risen Lord’s gift of the Holy Spirit” Resurrection and Pentecost
    “Dies Ecclesiae as the day on which the Christian community gathers for the celebration”
    “Dies hominis as the day of joy, rest and fraternal charity.”
    1. Finally, it is particularly urgent nowadays to remember that the day of the Lord is also a day of rest from work. It is greatly to be hoped that this fact will also be recognized by civil society, so that individuals can be permitted to refrain from work without being penalized. 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. As I have had occasion to say, “work is of fundamental importance to the fulfilment of the human being and to the development of society. Thus, it must always be organized and carried out with full respect for human dignity and must always serve the common good. At the same time, it is indispensable that people not allow themselves to be enslaved by work or to idolize it, claiming to find in it the ultimate and definitive meaning of life.” (209) 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. (210)

    “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 … 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’ (208)” (SacCar 73).

    The importance of Sunday as the Dies Ecclesiae brings us back to the intrinsic relationship between Jesus’ victory over evil and death, and our membership in his ecclesial body. On the Lord’s Day, each Christian rediscovers the communal dimension of his life as one who has been redeemed. Taking part in the liturgy and receiving the Body and Blood of Christ intensifies and deepens our belonging to the one who died for us (cf. 1 Cor 6:19ff; 7:23). Truly, whoever eats of Christ lives for him. The eucharistic mystery helps us to understand the profound meaning of the communio sanctorum. Communion always and inseparably has both a vertical and a horizontal sense: it is communion with God and communion with our brothers and sisters. Both dimensions mysteriously converge in the gift of the Eucharist. “Wherever communion with God, which is communion with the Father, with the Son and with the Holy Spirit, is destroyed, the root and source of our communion with one another is destroyed. And wherever we do not live communion among ourselves, communion with the Triune God is not alive and true either.”(215) Called to be members of Christ and thus members of one another (cf. 1 Cor 12:27), we are a reality grounded ontologically in Baptism and nourished by the Eucharist, a reality that demands visible expression in the life of our communities. The eucharistic form of Christian life is clearly an ecclesial and communitarian form. Through the Diocese and the parish, the fundamental structures of the Church in a particular territory, each individual believer can experience concretely what it means to be a member of Christ’s Body. Associations, ecclesial movements and new communities – with their lively charisms bestowed by the Holy Spirit for the needs of our time – together with Institutes of Consecrated Life, have a particular responsibility for helping to make the faithful conscious that they belong to the Lord (cf. Rom 14:8). Secularization, with its inherent emphasis on individualism, has its most negative effects on individuals who are isolated and lack a sense of belonging. Christianity, from its very beginning, has meant fellowship, a network of relationships constantly strengthened by hearing God’s word and sharing in the Eucharist, and enlivened by the Holy Spirit.
