A pilgrim people
37. As the Church journeys through time, the reference to Christ's Resurrection and the weekly recurrence of this solemn memorial help to remind us of the pilgrim and eschatological character of the People of God. Sunday after Sunday the Church moves towards the final "Lord's Day", that Sunday which knows no end. The expectation of Christ's coming is inscribed in the very mystery of the Church(55) and is evidenced in every Eucharistic celebration. But, with its specific remembrance of the glory of the Risen Christ, the Lord's Day recalls with greater intensity the future glory of his "return". This makes Sunday the day on which the Church, showing forth more clearly her identity as "Bride", anticipates in some sense the eschatological reality of the heavenly Jerusalem. Gathering her children into the Eucharistic assembly and teaching them to wait for the "divine Bridegroom", she engages in a kind of "exercise of desire",(56) receiving a foretaste of the joy of the new heavens and new earth, when the holy city, the new Jerusalem, will come down from God, "prepared as a bride adorned for her husband" (Rev 21:2).
The day of hope
38. Viewed in this way, Sunday is not only the day of faith, but is also the day of Christian hope. To share in "the Lord's Supper" is to anticipate the eschatological feast of the "marriage of the Lamb" (Rev 19:9). Celebrating this memorial of Christ, risen and ascended into heaven, the Christian community waits "in joyful hope for the coming of our Saviour, Jesus Christ".(57) Renewed and nourished by this intense weekly rhythm, Christian hope becomes the leaven and the light of human hope. This is why the Prayer of the Faithful responds not only to the needs of the particular Christian community but also to those of all humanity; and the Church, coming together for the Eucharistic celebration, shows to the world that she makes her own "the joys and hopes, the sorrows and anxieties of people today, especially of the poor and all those who suffer".(58) With the offering of the Sunday Eucharist, the Church crowns the witness which her children strive to offer every day of the week by proclaiming the Gospel and practising charity in the world of work and in all the many tasks of life; thus she shows forth more plainly her identity "as a sacrament, or sign and instrument of intimate union with God and of the unity of the entire human race".(59)
