Christ is present on the Altar, but Memorial A referes to Him in the 3rd Person. That is kind of rude, don’t you think?
No, not rude at all. Lots of prayers refer to Christ in the third person after the consecration. From the Roman Canon alone, consider:
Father, we celebrate the memory of Christ, your Son. We, your people and your ministers, recall his passion, his resurrection from the dead, and his ascension into glory . . . .
Almighty God, we pray that your angel may take this sacrifice to your altar in heaven. Then, as we receive from this altar the sacred body and blood of your Son, let us be filled with every grace and blessing. . . .
Through Christ our Lord you give us all these gifts. You fill them with life and goodness, you bless them and make them holy.
Frankly, if anything is out of place here, it’s the acclamation to Christ – which, let it be remembered, is purely a “Novus Ordo novelty,” as some would put it. Traditionally, the prayers here are all directed to the Father; indeed we pray the Our Father (“in the words our Savior taught us”) while the consecrated Eucharist just sits there on the altar.
I’m all for correct translations from the Latin, and if “Christ has died, Christ is risen” isn’t in the Latin, then it shouldn’t be in the English. But let’s not pretend that the “memorial acclamation” to Christ has a millennium of history and a deep theology to it which is being contravened by speaking of Christ in the third person. As far as I’m aware, the “memorial acclamation” was invented in 1969, and Memorial Acclamation A was introduced in 1973 . . . giving us a whole four-year stretch of history in which the acclamation always spoke to Christ directly.
