The Eucharist is first and foremost praise and thanksgiving.
THE DIGNITY OF THE EUCHARISTIC CELEBRATION
48. Like the woman who anointed Jesus in Bethany, the Church has feared no “extravagance”, devoting the best of her resources to expressing her wonder and adoration before the unsurpassable gift of the Eucharist. No less than the first disciples charged with preparing the “large upper room”, she has felt the need, down the centuries and in her encounters with different cultures, to celebrate the Eucharist in a setting worthy of so great a mystery. In the wake of Jesus’ own words and actions, and building upon the ritual heritage of Judaism, the Christian liturgy was born. Could there ever be an adequate means of expressing the acceptance of that self-gift which the divine Bridegroom continually makes to his Bride, the Church, by bringing the Sacrifice offered once and for all on the Cross to successive generations of believers and thus becoming nourishment for all the faithful? Though the idea of a “banquet” naturally suggests familiarity, the Church has never yielded to the temptation to trivialize this “intimacy” with her Spouse by forgetting that he is also her Lord and that the “banquet” always remains a sacrificial banquet marked by the blood shed on Golgotha. The Eucharistic Banquet is truly a “sacred” banquet, in which the simplicity of the signs conceals the unfathomable holiness of God: O sacrum convivium, in quo Christus sumitur! The bread which is broken on our altars, offered to us as wayfarers along the paths of the world, is panis angelorum, the bread of angels, which cannot be approached except with the humility of the centurion in the Gospel: “Lord, I am not worthy to have you come under my roof ” (Mt 8:8; Lk7:6).
49. With this heightened sense of mystery, we understand how the faith of the Church in the mystery of the Eucharist has found historical expression not only in the demand for an interior disposition of devotion, but also in outward forms meant to evoke and emphasize the grandeur of the event being celebrated. This led progressively to the development of a particular form of regulating the Eucharistic liturgy, with due respect for the various legitimately constituted ecclesial traditions. On this foundation a rich artistic heritage also developed. Architecture, sculpture, painting and music, moved by the Christian mystery, have found in the Eucharist, both directly and indirectly, a source of great inspiration.
58. In the Eucharist the Church is completely united to Christ and his sacrifice, and makes her own the spirit of Mary. This truth can be understood more deeply by re-reading the Magnificat in a Eucharistic key. The Eucharist, like the Canticle of Mary, is first and foremost praise and thanksgiving. When Mary exclaims: “My soul magnifies the Lord and my spirit rejoices in God my Saviour”, she already bears Jesus in her womb. She praises God “through” Jesus, but she also praises him “in” Jesus and “with” Jesus. This is itself the true “Eucharistic attitude”.
