above (Q. 76, A. 4), the accidents of
Christ's body are in this sacrament by real concomitance, but not by
the power of the sacrament, whereby the substance of Christ's body
comes to be there. And therefore the power of the sacramental words
extends to this, that the body, i.e. Christ's, is under this
sacrament, whatever accidents really exist in it.

FOURTH ARTICLE [III, Q. 81, Art. 4]

Whether, If This Sacrament Had Been Reserved in a Pyx, or Consecrated
at the Moment of Christ's Death by One of the Apostles, Christ
Himself Would Have Died There?

Objection 1: It seems that if this sacrament had been reserved in a
pyx at the moment of Christ's death, or had then been consecrated by
one of the apostles, that Christ would not have died there. For
Christ's death happened through His Passion. But even then He was in
this sacrament in an impassible manner. Therefore, He could not die
in this sacrament.

Obj. 2: Further, on the death of Christ, His blood was separated from
the body. But His flesh and blood are together in this sacrament.
Therefore He could not die in this sacrament.

Obj. 3: Further, death ensues from the separation of the soul from
the body. But both the body and the soul of Christ are contained in
this sacrament. Therefore Christ could not die in this sacrament.

_On the contrary,_ The same Christ Who was upon the cross would have
been in this sacrament. But He died upon the cross. Therefore, if
this sacrament had been reserved, He would have died therein.

_I answer that,_ Christ's body is substantially the same in this
sacrament, as in its proper species, but not after the same fashion;
because in its proper species it comes in contact with surrounding
bodies by its own dimensions: but it does not do so as it is in this
sacrament, as stated above (A. 3). And therefore, all that belongs to
Christ, as He is in Himself, can be attributed to Him both in His
proper species, and as He exists in the sacrament; such as to live,
to die, to grieve, to be animate or inanimate, and the like; while
all that belongs to Him in relation to outward bodies, can be
attributed to Him as He exists in His proper species, but not as He
is in this sacrament; such as to be mocked, to be spat upon, to be
crucified, to be scourged, and the rest. Hence some have composed
this verse:

"Our Lord can grieve beneath the sacramental veils
But cannot feel the piercing of the thorns and nails."
