In the Roman liturgy, when the priest has made the offering of the bread and the wine, he bows to the altar and prays quietly: “Lord God, we ask you to receive us and be pleased with the sacrifice we offer you with humble and contrite hearts”. In this way, together with the whole assembly of the faithful, he prepares to enter into the heart of the Eucharistic Mystery, into the heart of that heavenly liturgy to which the Second Reading from Revelation refers. St John presents an Angel who offers “much incense to mingle with the prayers of all the saints upon the golden altar before the throne” of God (cf. Rv 8: 3). The altar of the sacrifice becomes in a certain way the meeting point between Heaven and earth; the centre, we might say, of the One Church that is heavenly yet at the same time a pilgrim on this earth where, amidst the persecutions of the world and the consolations of God, disciples of the Lord proclaim his Passion and his death until he comes in glory (cf. Lumen Gentium, n. 8). Indeed, every Eucharistic Celebration already anticipates Christ’s triumph over sin and over the world and in the mystery shows the radiance of the Church, “the spotless spouse of the spotless Lamb. It is she whom Christ loved and for whom he delivered himself up that he might sanctify her’” (ibid., n. 6).
