Whether man is preserved by this sacrament from future sins?

❌ Objection 1 : It seems that man is not preserved by this sacrament from future sins. For there are many that receive this sacrament worthily, who afterwards fall into sin. Now this would not happen if this sacrament were to preserve them from future sins. Consequently, it is not an effect of this sacrament to preserve from future sins.

❌ Objection 2 : Further, the Eucharist is the sacrament of charity, as stated above (Article [4]). But charity does not seem to preserve from future sins, because it can be lost through sin after one has possessed it, as was stated in the SS, Question [24], Article [11]. Therefore it seems that this sacrament does not preserve man from sin.

❌ Objection 3 : Further, the origin of sin within us is "the law of sin, which is in our members," as declared by the Apostle (Rm. 7:23). But the lessening of the fomes, which is the law of sin, is set down as an effect not of this sacrament, but rather of Baptism. Therefore preservation from sin is not an effect of this sacrament.
