GIRM 80 through 89 covers the Communion Rite. Lest there’s any doubt that meal, food, and spiritual nourishment join sacrifice as part of the meaning of the Eucharist, here’s the black in blue of it:
80. Since the celebration of the Eucharist is the Paschal Banquet, it is desirable that in accordance with the Lord’s command his Body and Blood should be received as spiritual food by those of the faithful who are properly disposed. This is the sense of the fraction and the other preparatory rites by which the faithful are led more immediately to Communion.
The preparatory rites for the Communion procession continue the bivalent sense of meal + sacrifice. It’s good to recall when the usual liturgy tussles on this issue break out. Just ask: what do the rites tell us?
