Whether infusion of grace is necessary for the remission of venial sins?
Objection 1: It would seem that infusion of grace is necessary for the remission of venial sins. Because an effect is not produced without its proper cause. Now the proper cause of the remission of sins is grace; for man's sins are not forgiven through his own merits; wherefore it is written (Eph. 2:4,5): "God, Who is rich in mercy, for His exceeding charity, wherewith He loved us, even when we were dead in sins, hath quickened us together in Christ, by Whose grace you are saved." Therefore venial sins are not forgiven without infusion of grace.
Objection 2: Further, venial sins are not forgiven without Penance. Now grace is infused, in Penance as in the other sacraments of the New Law. Therefore venial sins are not forgiven without infusion of grace.
Objection 3: Further, venial sin produces a stain on the soul. Now a stain is not removed save by grace which is the spiritual beauty of the soul. Therefore it seems that venial sins are not forgiven without infusion of grace.
On the contrary, The advent of venial sin neither destroys nor diminishes grace, as stated in the SS, Q 24, A 10. Therefore, in like manner, an infusion of grace is not necessary in order to remove venial sin.
I answer that, Each thing is removed by its contrary. But venial sin is not contrary to habitual grace or charity, but hampers its act, through man being too much attached to a created good, albeit not in opposition to God, as stated in the FS, Q 88, A 1; SS, Q 24, A 10. Therefore, in order that venial sin be removed, it is not necessary that habitual grace be infused, but a movement of grace or charity suffices for its forgiveness.
Nevertheless, since in those who have the use of free-will (in whom alone can there be venial sins), there can be no infusion of grace without an actual movement of the free-will towards God and against sin, consequently whenever grace is infused anew, venial sins are forgiven.
Reply to Objection 1: Even the forgiveness of venial sins is an effect of grace, in virtue of the act which grace produces anew, but not through any habit infused anew into the soul.
Reply to Objection 2: Venial sin is never forgiven without some act, explicit or implicit, of the virtue of penance, as stated above (A 1): it can, however, be forgiven without the sacrament of Penance, which is formally perfected by the priestly absolution, as stated above (Q 87, A 2). Hence it does not follow that infusion of grace is required for the forgiveness of venial sin, for although this infusion takes place in every sacrament, it does not occur in every act of virtue.
Reply to Objection 3: Just as there are two kinds of bodily stain, one consisting in the privation of something required for beauty, e.g. the right color or the due proportion of members, and another by the introduction of some hindrance to beauty, e.g. mud or dust; so too, a stain is put on the soul, in one way, by the privation of the beauty of grace through mortal sin, in another, by the inordinate inclination of the affections to some temporal thing, and this is the result of venial sin. Consequently, an infusion of grace is necessary for the removal of mortal sin, but in order to remove venial sin, it is necessary to have a movement proceeding from grace, removing the inordinate attachment to the temporal thing.
III · Q. 87, Art. 3: Whether venial sins are removed by the sprinkling of holy water and the like?
Whether venial sins are removed by the sprinkling of holy water and the like?
Objection 1: It would seem that venial sins are not removed by the sprinkling of holy water, a bishop's blessing, and the like. For venial sins are not forgiven without Penance, as stated above (A 1). But Penance suffices by itself for the remission of venial sins. Therefore the above have nothing to do with the remission of venial sins.
Objection 2: Further, each of the above bears the same relation to one venial sin as to all. If therefore, by means of one of them, some venial sin is remitted, it follows that in like manner all are remitted, so that by beating his breast once, or by being sprinkled once with holy water, a man would be delivered from all his venial sins, which seems unreasonable.
Objection 3: Further, venial sins occasion a debt of some punishment, albeit temporal; for it is written (1 Cor. 3:12, 15) of him that builds up "wood, hay, stubble" that "he shall be saved, yet so as by fire." Now the above things whereby venial sins are said to be taken away, contain either no punishment at all, or very little. Therefore they do not suffice for the full remission of venial sins.
On the contrary, Augustine says in De Poenitentia [*Hom. 30 inter 1; Ep. cclxv] that "for our slight sins we strike our breasts, and say: Forgive us our trespasses," and so it seems that striking one's breast, and the Lord's Prayer cause the remission of venial sins: and the same seems to apply to the other things.
I answer that, As stated above (A 2), no infusion of fresh grace is required for the forgiveness of a venial sin, but it is enough to have an act proceeding from grace, in detestation of that venial sin, either explicit or at least implicit, as when one is moved fervently to God. Hence, for three reasons, certain things cause the remission of venial sins: first, because they imply the infusion of grace, since the infusion of grace removes venial sins, as stated above (A 2); and so, by the Eucharist, Extreme Unction, and by all the sacraments of the New Law without exception, wherein grace is conferred, venial sins are remitted. Secondly, because they imply a movement of detestation for sin, and in this way the general confession [*i.e. the recital of the Confiteor or of an act of contrition], the beating of one's breast, and the Lord's Prayer conduce to the remission of venial sins, for we ask in the Lord's Prayer: "Forgive us our trespasses." Thirdly, because they include a movement of reverence for God and Divine things; and in this way a bishop's blessing, the sprinkling of holy water, any sacramental anointing, a prayer said in a dedicated church, and anything else of the kind, conduce to the remission of venial sins.
Reply to Objection 1: All these things cause the remission of venial sins, in so far as they incline the soul to the movement of penance, viz., the implicit or explicit detestation of one's sins.
Reply to Objection 2: All these things, so far as they are concerned, conduce to the remission of all venial sins: but the remission may be hindered as regards certain venial sins, to which the mind is still actually attached, even as insincerity sometimes impedes the effect of Baptism.
Reply to Objection 3: By the above things, venial sins are indeed taken away as regards the guilt, both because those things are a kind of satisfaction, and through the virtue of charity whose movement is aroused by such things.
Yet it does not always happen that, by means of each one, the whole guilt of punishment is taken away, because, in that case, whoever was entirely free from mortal sin, would go straight to heaven if sprinkled with holy water: but the debt of punishment is remitted by means of the above, according to the movement of fervor towards God, which fervor is aroused by such things, sometimes more, sometimes less.
