rament) irreverently; and such a one eats and drinks judgment,
i.e. damnation, unto himself." Therefore, he that is in mortal sin,
by taking the sacrament heaps sin upon sin, rather than obtains
forgiveness of his sin.

_I answer that,_ The power of this sacrament can be considered in two
ways. First of all, in itself: and thus this sacrament has from
Christ's Passion the power of forgiving all sins, since the Passion
is the fount and cause of the forgiveness of sins.

Secondly, it can be considered in comparison with the recipient of
the sacrament, in so far as there is, or is not, found in him an
obstacle to receiving the fruit of this sacrament. Now whoever is
conscious of mortal sin, has within him an obstacle to receiving the
effect of this sacrament; since he is not a proper recipient of this
sacrament, both because he is not alive spiritually, and so he ought
not to eat the spiritual nourishment, since nourishment is confined
to the living; and because he cannot be united with Christ, which is
the effect of this sacrament, as long as he retains an attachment
towards mortal sin. Consequently, as is said in the book _De Eccles.
Dogm.:_ "If the soul leans towards sin, it is burdened rather than
purified from partaking of the Eucharist." Hence, in him who is
conscious of mortal sin, this sacrament does not cause the
forgiveness of sin.

Nevertheless this sacrament can effect the forgiveness of sin in two
ways. First of all, by being received, not actually, but in desire;
as when a man is first justified from sin. Secondly, when received by
one in mortal sin of which he is not conscious, and for which he has
no attachment; since possibly he was not sufficiently contrite at
first, but by approaching this sacrament devoutly and reverently he
obtains the grace of charity, which will perfect his contrition and
bring forgiveness of sin.

Reply Obj. 1: We ask that this sacrament may be the "cleansing of
crimes," or of those sins of which we are unconscious, according to
Ps. 18:13: "Lord, cleanse me from my hidden sins"; or that our
contrition may be perfected for the forgiveness of our sins; or that
strength be bestowed on us to avoid sin.

Reply Obj. 2: Baptism is spiritual generation, which is a transition
from spiritual non-being into spiritual being, and is given by way of
ablution. Consequently, in both respects he who is conscious of
mortal sin does not improperly approach Baptism. But in this
sacrament man rec
