The Presence of Angels at the Eucharist
The angels are present especially at the Eucharistic Sacrifice. The Mass is, actually, a sacramental participation in the liturgy of heaven, the cult* officially rendered to the Trinity by the full host of the spiritual creation. The presence of the angels introduces the Eucharist into heaven itself. They help to surround it with a sacred mystery.
“The angels surround the priest,” writes St. John Chrysostom. “The whole sanctuary and the space before the altar is filled with the heavenly Powers come to honor Him who is present upon the altar.” And elsewhere: “Think now of what kind of choir you are going to enter. Although vested with a body, you have been judged worthy to join the Powers of heaven in singing the praises of Him who is Lord of all.” “Behold the royal table. The angels serve at it. The Lord Himself is present.”
There is only one priestly activity, and that is Jesus Christ’s. By it the whole of creation glorifies the Trinity. This is this same activity that is offered by the angels in heaven and the saints on earth. This participation appears in the New Testament, where the liturgy of the Church is presented as a participation in that of the angels. Thus, in the letter to the Hebrews, we read: “But you have come to Mount Sion, and to the city of the living God, the heavenly Jerusalem, and to the company of many thousands of angels, and to the Church of the firstborn who are enrolled in the heavens, and to God, the judge of all, and to the spirits of the just made perfect, and to Jesus, mediator of a new testament, and to a sprinkling of blood which speaks better than Abel.”
As for the Apocalypse, it is the vision of the Christian Sunday worship that the visionary sees as prolonged in the liturgy of heaven.
The Heavenly Liturgy
The angels are associated with the different parts of the sacrifice. Theodore of Mopsuestia shows them symbolized by the ministers who arrange the offerings upon the altar: “By means of the deacons who minister in what is being accomplished, we can see in spirit the invisible Powers ministering as they assist in this ineffable liturgy.”
Further on he adds, “You must realize that there is an image of the invisible Powers in this service that the deacons are charged with now, as they bear the offering for the oblation . . . And when they have brought it in, it is placed upon the holy altar by the angels for the perfect fulfillment of the Passion. The deacons who spread the cloths upon the altar recall the burial linens; and those who, once the sacred Body has been produced, stand on either side and fan the air around it, represent the angels who remained by Christ all the while He was dead, to honor Him, until they had seen His Resurrection.”
