St Thomas Aquinas Interpretation.
The priest does not pray that the sacramental species may be borne up to heaven; nor that Christ’s true body may be borne thither, for it does not cease to be there; but he offers this prayer for Christ’s mystical body, which is signified in this sacrament, that the angel standing by at the divine mysteries may present to God the prayers of both priest and people, according to the Apocalypse, ‘And the smoke of incense of the prayers of the saints ascended up before God from the hand of the angel.’ (Apocalypse 8:4) But God’s altar on high means either the Church triumphant, unto which we pray to be translated, or else God Himself, in whom we ask to share; because it is said of this altar, ‘Thou shall not go up by steps unto My altar,’ i.e., thou shall make no steps towards the Trinity. (Exodus 20:26) Or else by the angel we are to understand Christ Himself, who is the Angel of great council (Isaias 9:6), who unites His mystical body with God the Father and the Church Triumphant." (Summa theol., IIIa, q.83, a.4, ad 9.)
In these few words the Angelic Doctor says all that may be said regarding the meaning of this prayer. He leaves us free to favor one or the other interpretation. However, apart from the discussion of the words, this prayer contains a certain aspect that is not easy to express in earthly language, for, its meaning is in the spheres of heaven, far beyond the reach of earthly comprehension. Its meaning approaches the most sacred precincts of the heavenly courts, and penetrates into the regions where angels dwell. Here the most blessed spirits hover before the presence of the divine Majesty, singing hymns of praise and adoration to the name of God, and, here in the celestial sanctuary, angels chant the glories of God forever. Here, in the holy of holies, the melodies of the angelic choir re-echo through all eternity.
I think about the time when we pray beside the bed of a dying loved one, and how we call on the Angel of God to carry our love one on his wings to the Father.
