SECOND ARTICLE [III, Q. 76, Art. 2]

Whether the Whole Christ Is Contained Under Each Species of This
Sacrament?

Objection 1: It seems that the whole Christ is not contained under
both species of this sacrament. For this sacrament is ordained for
the salvation of the faithful, not by virtue of the species, but by
virtue of what is contained under the species, because the species
were there even before the consecration, from which comes the power
of this sacrament. If nothing, then, be contained under one species,
but what is contained under the other, and if the whole Christ be
contained under both, it seems that one of them is superfluous in
this sacrament.

Obj. 2: Further, it was stated above (A. 1, ad 1) that all the other
parts of the body, such as the bones, nerves, and the like, are
comprised under the name of flesh. But the blood is one of the parts
of the human body, as Aristotle proves (De Anima Histor. i). If,
then, Christ's blood be contained under the species of bread, just as
the other parts of the body are contained there, the blood ought not
to be consecrated apart, just as no other part of the body is
consecrated separately.

Obj. 3: Further, what is once _in being_ cannot be again _in
becoming._ But Christ's body has already begun to be in this
sacrament by the consecration of the bread. Therefore, it cannot
begin again to be there by the consecration of the wine; and so
Christ's body will not be contained under the species of the wine,
and accordingly neither the entire Christ. Therefore the whole Christ
is not contained under each species.

_On the contrary,_ The gloss on 1 Cor. 11:25, commenting on the word
"Chalice," says that "under each species," namely, of the bread and
wine, "the same is received"; and thus it seems that Christ is entire
under each species.

_I answer that,_ After what we have said above (A. 1), it must be
held most certainly that the whole Christ is under each sacramental
species yet not alike in each. For the body of Christ is indeed
present under the species of bread by the power of the sacrament,
while the blood is there from real concomitance, as stated above (A.
1, ad 1) in regard to the soul and Godhead of Christ; and under the
species of wine the blood is present by the power of the sacramen
