When the principal celebrant does not consume both species the Sacrifice is incomplete. An incomplete Sacrifice does not make for a valid Mass.

Walking Home, and others,
First,
please take my assurance (for what it is worth) that I strive for utter and complete orthodoxy – If anything I say is not consistent with the authentic magisterial teaching of the Church it ought to be rejected.
The reason I felt it necessary to state the above is because what follows is: a)I question the surety of the statement “the Mass is invalid if the priest does not communicate under both species”; b) a possible contradiction of Walking Home; and c) a possible agreement with diggerdomer (whom I have heretofore tended to *disagree *with on several issues – no offense intended, dd.)
Now to it:
Walking Home, you pointed us to Fr. McNamara above. Unfortunately
he elsewhere says this (correctly, I believe):
Code:
This situation is different from one illustrated by a reader from the United Kingdom in which a priest forgot to receive from the chalice before distributing Communion and remembered only after the chalice had been emptied.
Technically this would be called an irregularity, as the priest is obliged to receive under both kinds. This error also occurs sometimes at large concelebrations at which, due to lack of careful planning, some priests are left by the wayside in the distribution of the chalice.
** While it should not happen, it does not affect the validity of the Mass** for either priest or faithful. The only thing to be done about it is to learn the lesson the hard way, ask forgiveness for any culpable negligence, and be more careful and attentive the next time.
Walking Home you are correct, of course, that the priest’s communion completes the sacrifice (this is the teaching of the Church). But what does that mean, exactly? It seems to me something distinct from “the sacrifice is incomplete”. How so? Because completing the
sacrifice means that the sacrifice has already occurred (i.e. at the double consecration). It is not, then, a matter of the sacrifice being incomplete in the sense of not occurring, I would say. Your phrase “the sacrifice is incomplete” would certainly be appropriate to describe a priest forgetting and not yet consecrating the precious blood. . . because until he or another priest does so the sacrifice would not have occurred.
Strictly speaking, though, the above doesn’t tell us about the validity or lack of validity (to use those terms) of the Mass – it just tells us that the sacrifice occurs after the double consecration. Regarding the priest’s communion, we know that it belongs to the integrity of the Mass. Here is
Mediator Dei:
- The august sacrifice of the altar is concluded with communion or the partaking of the divine feast. But, as all know, the integrity of the sacrifice only requires that the priest partake of the heavenly food.
Later the Holy Father restates it as the communion belonging to the “integrity of the Mass” (115)
We find the same in the old
Catholic Encyclopedia:
the Communion of the priest is not the sacrifice, but only the completion of, and participation in, the sacrifice; it belongs therefore not to the essence, but to the integrity of the sacrifice.( “Sacrifice of the Mass,” J. Pohle, The Catholic Encyclopedia, 1914 (San Diego, Catholic Answers, 2007)
As to whether or not this lack of integrity means the Mass itself is invalid, I’m leaning towards no. Fr. Hardon says in his Catholic Dictionary, under
Double Consecration:
The separate consecration of the bread and wine into the body and blood of Christ. This separate consecration constitutes the essence of the Mass as a renewal of Calvary. It symbolizes the death of Christ caused by the separation of his body and blood. All other parts of the Mass are not absolutely essential, even the priest’s Communion, which, though gravely binding, belongs rather to the integrity than to the essence of the Eucharistic sacrifice.
St. Thomas in the Summa mentions two kinds of integrity: that which belongs to the essence of a thing and that which belongs to its use. I
think here we
might being speaking of the latter type of integrity.
I’ll just note again, that whatever else it is, the priest’s communion if gravely binding. Very serious in Canon Law. It also seems to be a Divine command on the part of Christ to his priests.
So, that is where I am at the moment. Can anyone help me see it more clearly?
Walking Home, I welcome your thoughts. Do you know of any authoritative source that might help clear this up?
Thanks,
VC
P.S. JRKH, you are right, too, that the above discussion doesn’t bear directly on your question. I think it might have some oblique bearing though. Hope you don’t mind.
