FIRST ARTICLE [III, Q. 79, Art. 1]

Whether Grace Is Bestowed Through This Sacrament?

Objection 1: It seems that grace is not bestowed through this
sacrament. For this sacrament is spiritual nourishment. But
nourishment is only given to the living. Therefore since the
spiritual life is the effect of grace, this sacrament belongs only to
one in the state of grace. Therefore grace is not bestowed through
this sacrament for it to be had in the first instance. In like manner
neither is it given so as grace may be increased, because spiritual
growth belongs to the sacrament of Confirmation, as stated above (Q.
72, A. 1). Consequently, grace is not bestowed through this sacrament.

Obj. 2: Further, this sacrament is given as a spiritual refreshment.
But spiritual refreshment seems to belong to the use of grace rather
than to its bestowal. Therefore it seems that grace is not given
through this sacrament.

Obj. 3: Further, as was said above (Q. 74, A. 1), "Christ's body is
offered up in this sacrament for the salvation of the body, and His
blood for that of the soul." Now it is not the body which is the
subject of grace, but the soul, as was shown in the Second Part
(I-II, Q. 110, A. 4). Therefore grace is not bestowed through this
sacrament, at least so far as the body is concerned.

_On the contrary,_ Our Lord says (John 6:52): "The bread which I will
give, is My flesh for the life of the world." But the spiritual life
is the effect of grace. Therefore grace is bestowed through this
sacrament.

_I answer that,_ The effect of this sacrament ought to be considered,
first of all and principally, from what is contained in this
sacrament, which is Christ; Who, just as by coming into the world, He
visibly bestowed the life of grace upon the world, according to John
1:17: "Grace and truth came by Jesus Christ," so also, by coming
sacramentally into man causes the life of grace, according to John
6:58: "He that eateth Me, the same also shall live by Me." Hence
Cyril says on Luke 22:19: "God's life-giving Word by uniting Himself
with His own flesh, made it to be productive of life. For it was
becoming that He should be united somehow with bodies through His
sacred flesh and precious blood, which we receive in a life-giving
blessing in the bread and wine."

Secondly, it is considered on the part of what i
