Summa Theologica

Objection 1: It seems that the aforesaid expressions are not true. Because when we say: "This is My body," the word "this" designates a substance. But according to what was said above (AA,4, ad 3; Q[75], AA,7), when the pronoun "this" is spoken, the substance of the bread is still there, because the transubstantiation takes place in the last instant of pronouncing the words. But it is false to say: "Bread is Christ's body." Consequently this expression, "This is My body," is false.

Objection 2: Further, the pronoun "this" appeals to the senses. But the sensible species in this sacrament are neither Christ's body nor even its accidents. Therefore this expression, "This is My body," cannot be true.

Objection 3: Further, as was observed above (A[4], ad 3), these words, by their signification, effect the change of the bread into the body of Christ. But an effective cause is understood as preceding its effect. Therefore the meaning of these words is understood as preceding the change of the bread into the body of Christ. But previous to the change this expression, "This is My body," is false. Therefore the expression is to be judged as false simply; and the same reason holds good of the other phrase: "This is the chalice of My blood," etc.

On the contrary, These words are pronounced in the person of Christ, Who says of Himself (Jn. 14:6): "I am the truth."

I answer that, There have been many opinions on this point. Some have said that in this expression, "This is My body," the word "this" implies demonstration as conceived, and not as exercised, because the whole phrase is taken materially, since it is uttered by a way of narration: for the priest relates that Christ said: "This is My body."

But such a view cannot hold good, because then these words would not be applied to the corporeal matter present, and consequently the sacrament would not be valid: for Augustine says (Tract. lxxx in Joan.): "The word is added to the element, and this becomes a sacrament." Moreover this solution ignores entirely the difficulty which this question presents: for there is still the objection in regard to the first uttering of these words by Christ; since it is evident that then they were employed, not materially, but significatively. And therefore it must be said that even when spoken by the priest they are taken significatively, and not merely materially. Nor does it matter that the priest pronounces them by way of recital, as though they were spoken by Christ, because owing to Christ's infinite power, just as through contact with His flesh the regenerative power entered not only into the waters which came into contact with Christ, but into all waters throughout the whole world and during all future ages, so likewise from Christ's uttering these words they derived their consecrating power, by whatever priest they be uttered, as if Christ present were saying them.

And therefore others have said that in this phrase the word "this" appeals, not to the senses, but to the intellect; so that the meaning is, "This is My body"—i.e. "The thing signified by 'this' is My body." But neither can this stand, because, since in the sacraments the effect is that which is signified, from such a form it would not result that Christ's body was in very truth in this sacrament, but merely as in a sign, which is heretical, as stated above (Q[85], A[1]).

Consequently, others have said that the word "this" appeals to the senses; not at the precise instant of its being uttered, but merely at the last instant thereof; as when a man says, "Now I am silent," this adverb "now" points to the instant immediately following the speech: because the sense is: "Directly these words are spoken I am silent." But neither can this hold good, because in that case the meaning of the sentence would be: "My body is My body," which the above phrase does not effect, because this was so even before the utterance of the words: hence neither does the aforesaid sentence mean this.

Consequently, then, it remains to be said, as stated above(A[4]), that this sentence possesses the power of effecting the conversion of the bread into the body of Christ. And therefore it is compared to other sentences, which have power only of signifying and not of producing, as the concept of the practical intellect, which is productive of the thing, is compared to the concept of our speculative intellect which is drawn from things. because "words are signs of concepts," as the Philosopher says (Peri Herm. i). And therefore as the concept of the practical intellect does not presuppose the thing understood, but makes it, so the truth of this expression does not presuppose the thing signified, but makes it; for such is the relation of God's word to the things made by the Word. Now this change takes place not successively, but in an instant, as stated above (Q[77], A[7]). Consequently one must understand the aforesaid expression with reference to the last instant of the words being spoken, yet not so that the subject may be understood to have stood for that which is the term of the conversion; viz. that the body of Christ is the body of Christ; nor again that the subject be understood to stand for that which it was before the conversion, namely, the bread. but for that which is commonly related to both, i.e. that which is contained in general under those species. For these words do not make the body of Christ to be the body of Christ, nor do they make the bread to be the body of Christ; but what was contained under those species, and was formerly bread, they make to be the body of Christ. And therefore expressly our Lord did not say: "This bread is My body," which would be the meaning of the second opinion; nor "This My body is My body," which would be the meaning of the third opinion: but in general: "This is My body," assigning no noun on the part of the subject, but only a pronoun, which signifies substance in common, without quality, that is, without a determinate form.

Reply to Objection 1: The term "this" points to a substance, yet without determining its proper nature, as stated above.

Reply to Objection 2: The pronoun "this" does not indicate the accidents, but the substance underlying the accidents, which at first was bread, and is afterwards the body of Christ, which body, although not informed by those accidents, is yet contained under them.

Reply to Objection 3: The meaning of this expression is, in the order of nature, understood before the thing signified, just as a cause is naturally prior to the effect; but not in order of time, because this cause has its effect with it at the same time, and this suffices for the truth of the expression.

Objection 1: It seems that the form of the consecration of the bread does not accomplish its effect until the form for the consecration of the wine be completed. For, as Christ's body begins to be in this sacrament by the consecration of the bread, so does His blood come to be there by the consecration of the wine. If, then, the words for consecrating the bread were to produce their effect before the consecration of the wine, it would follow that Christ's body would be present in this sacrament without the blood, which is improper.

Objection 2: Further, one sacrament has one completion: hence although there be three immersions in Baptism, yet the first immersion does not produce its effect until the third be completed. But all this sacrament is one, as stated above (Q[73], A[2]). Therefore the words whereby the bread is consecrated do not bring about their effect without the sacramental words whereby the wine is consecrated.

Objection 3: Further, there are several words in the form for consecrating the bread, the first of which do not secure their effect until the last be uttered, as stated above (A[4], ad 3). Therefore, for the same reason, neither do the words for the consecration of Christ's body produce their effect, until the words for consecrating Christ's blood are spoken.

On the contrary, Directly the words are uttered for consecrating the bread, the consecrated host is shown to the people to be adored, which would not be done if Christ's body were not there, for that would be an act of idolatry. Therefore the consecrating words of the bread produce their effect before. the words are spoken for consecrating the wine.

I answer that, Some of the earlier doctors said that these two forms, namely, for consecrating the bread and the wine, await each other's action, so that the first does not produce its effect until the second be uttered.

But this cannot stand, because, as stated above (A[5], ad 3), for the truth of this phrase, "This is My body," wherein the verb is in the present tense, it is required for the thing signified to be present simultaneously in time with the signification of the expression used; otherwise, if the thing signified had to be awaited for afterwards, a verb of the future tense would be employed, and not one of the present tense, so that we should not say, "This is My body," but "This will be My body." But the signification of this speech is complete directly those words are spoken. And therefore the thing signified must be present instantaneously, and such is the effect of this sacrament; otherwise it would not be a true speech. Moreover, this opinion is against the rite of the Church, which forthwith adores the body of Christ after the words are uttered.

Hence it must be said that the first form does not await the second in its action, but has its effect on the instant.

Reply to Objection 1: It is on this account that they who maintained the above opinion seem to have erred. Hence it must be understood that directly the consecration of the bread is complete, the body of Christ is indeed present by the power of the sacrament, and the blood by real concomitance; but afterwards by the consecration of the wine, conversely, the blood of Christ is there by the power of the sacrament, and the body by real concomitance, so that the entire Christ is under either species, as stated above (Q[76], A[2]).

Reply to Objection 2: This sacrament is one in perfection, as stated above (Q[73], A[2]), namely, inasmuch as it is made up of two things, that is, of food and drink, each of which of itself has its own perfection; but the three immersions of Baptism are ordained to one simple effect, and therefore there is no resemblance.

Reply to Objection 3: The various words in the form for consecrating the bread constitute the truth of one speech, but the words of the different forms do not, and consequently there is no parallel.

We must now consider the effects of this sacrament, and under this head there are eight points of inquiry:

(1) Whether this sacrament bestows grace?

(2) Whether the attaining of glory is an effect of this sacrament?

(3) Whether the forgiveness of mortal sin is an effect of this sacrament?

(4) Whether venial sin is forgiven by this sacrament?

(5) Whether the entire punishment due for sin is forgiven by this sacrament?

(6) Whether this sacrament preserves man from future sins?

(7) Whether this sacrament benefits others besides the recipients?

(8) Of the obstacles to the effect of 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.

Objection 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.

Objection 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 FS, 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 (Jn. 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 Jn. 1:17: "Grace and truth came by Jesus Christ," so also, by coming sacramentally into man causes the life of grace, according to Jn. 6:58: "He that eateth Me, the same also shall live by Me." Hence Cyril says on Lk. 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 is represented by this sacrament, which is Christ's Passion, as stated above (Q[74], A[1]; Q[76], A[2], ad 1). And therefore this sacrament works in man the effect which Christ's Passion wrought in the world. Hence, Chrysostom says on the words, "Immediately there came out blood and water" (Jn. 19:34): "Since the sacred mysteries derive their origin from thence, when you draw nigh to the awe-inspiring chalice, so approach as if you were going to drink from Christ's own side." Hence our Lord Himself says (Mat. 26:28): "This is My blood... which shall be shed for many unto the remission of sins."

Thirdly, the effect of this sacrament is considered from the way in which this sacrament is given; for it is given by way of food and drink. And therefore this sacrament does for the spiritual life all that material food does for the bodily life, namely, by sustaining, giving increase, restoring, and giving delight. Accordingly, Ambrose says (De Sacram. v): "This is the bread of everlasting life, which supports the substance of our soul." And Chrysostom says (Hom. xlvi in Joan.): "When we desire it, He lets us feel Him, and eat Him, and embrace Him." And hence our Lord says (Jn. 6:56): "My flesh is meat indeed, and My blood is drink indeed."

Fourthly, the effect of this sacrament is considered from the species under which it is given. Hence Augustine says (Tract. xxvi in Joan.): "Our Lord betokened His body and blood in things which out of many units are made into some one whole: for out of many grains is one thing made," viz. bread; "and many grapes flow into one thing," viz. wine. And therefore he observes elsewhere (Tract. xxvi in Joan.): "O sacrament of piety, O sign of unity, O bond of charity!"

And since Christ and His Passion are the cause of grace. and since spiritual refreshment, and charity cannot be without grace, it is clear from all that has been set forth that this sacrament bestows grace.

Reply to Objection 1: This sacrament has of itself the power of bestowing grace; nor does anyone possess grace before receiving this sacrament except from some desire thereof; from his own desire, as in the case of the adult. or from the Church's desire in the case of children, as stated above (Q[73], A[3]). Hence it is due to the efficacy of its power, that even from desire thereof a man procures grace whereby he is enabled to lead the spiritual life. It remains, then, that when the sacrament itself is really received, grace is increased, and the spiritual life perfected: yet in different fashion from the sacrament of Confirmation, in which grace is increased and perfected for resisting the outward assaults of Christ's enemies. But by this sacrament grace receives increase, and the spiritual life is perfected, so that man may stand perfect in himself by union with God.

Reply to Objection 2: This sacrament confers grace spiritually together with the virtue of charity. Hence Damascene (De Fide Orth. iv) compares this sacrament to the burning coal which Isaias saw (Is. 6:6): "For a live ember is not simply wood, but wood united to fire; so also the bread of communion is not simple bread but bread united with the Godhead." But as Gregory observes in a Homily for Pentecost, "God's love is never idle; for, wherever it is it does great works." And consequently through this sacrament, as far as its power is concerned, not only is the habit of grace and of virtue bestowed, but it is furthermore aroused to act, according to 2 Cor. 5:14: "The charity of Christ presseth us." Hence it is that the soul is spiritually nourished through the power of this sacrament, by being spiritually gladdened, and as it were inebriated with the sweetness of the Divine goodness, according to Cant 5:1: "Eat, O friends, and drink, and be inebriated, my dearly beloved."

Reply to Objection 3: Because the sacraments operate according to the similitude by which they signify, therefore by way of assimilation it is said that in this sacrament "the body is offered for the salvation of the body, and the blood for the salvation of the soul," although each works for the salvation of both, since the entire Christ is under each, as stated above (Q[76], A[2]). And although the body is not the immediate subject of grace, still the effect of grace flows into the body while in the present life we present "our [Vulg.: 'your'] members" as "instruments of justice unto God" (Rom. 6:13), and in the life to come our body will share in the incorruption and the glory of the soul.

Objection 1: It seems that the attaining of glory is not an effect of this sacrament. For an effect is proportioned to its cause. But this sacrament belongs to "wayfarers" [viatoribus], and hence it is termed "Viaticum." Since, then, wayfarers are not yet capable of glory, it seems that this sacrament does not cause the attaining of glory.

Objection 2: Further, given sufficient cause, the effect follows. But many take this sacrament who will never come to glory, as Augustine declares (De Civ. Dei xxi). Consequently, this sacrament is not the cause of attaining unto glory.

Objection 3: Further, the greater is not brought about by the lesser, for nothing acts outside its species. But it is the lesser thing to receive Christ under a strange species, which happens in this sacrament, than to enjoy Him in His own species, which belongs to glory. Therefore this sacrament does not cause the attaining of glory.

On the contrary, It is written (Jn. 6:52): "If any man eat of this bread, he shall live for ever." But eternal life is the life of glory. Therefore the attaining of glory is an effect of this sacrament.

I answer that, In this sacrament we may consider both that from which it derives its effect, namely, Christ contained in it, as also His Passion represented by it; and that through which it works its effect, namely, the use of the sacrament, and its species.

Now as to both of these it belongs to this sacrament to cause the attaining of eternal life. Because it was by His Passion that Christ opened to us the approach to eternal life, according to Heb. 9:15: "He is the Mediator of the New Testament; that by means of His death... they that are called may receive the promise of eternal inheritance." Accordingly in the form of this sacrament it is said: "This is the chalice of My blood, of the New and Eternal Testament."

In like manner the refreshment of spiritual food and the unity denoted by the species of the bread and wine are to be had in the present life, although imperfectly. but perfectly in the state of glory. Hence Augustine says on the words, "My flesh is meat indeed" (Jn. 6:56): "Seeing that in meat and drink, men aim at this, that they hunger not nor thirst, this verily nought doth afford save only this meat and drink which maketh them who partake thereof to be immortal and incorruptible, in the fellowship of the saints, where shall be peace, and unity, full and perfect."

Reply to Objection 1: As Christ's Passion, in virtue whereof this sacrament is accomplished, is indeed the sufficient cause of glory, yet not so that we are thereby forthwith admitted to glory, but we must first "suffer with Him in order that we may also be glorified" afterwards "with Him" (Rom. 8:17), so this sacrament does not at once admit us to glory, but bestows on us the power of coming unto glory. And therefore it is called "Viaticum," a figure whereof we read in 3 Kings 19:8: "Elias ate and drank, and walked in the strength of that food forty days and forty nights unto the mount of God, Horeb."

Reply to Objection 2: Just as Christ's Passion has not its effect in them who are not disposed towards it as they should be, so also they do not come to glory through this sacrament who receive it unworthily. Hence Augustine (Tract. xxvi in Joan.), expounding the same passage, observes: "The sacrament is one thing, the power of the sacrament another. Many receive it from the altar... and by receiving"... die... Eat, then, spiritually the heavenly "bread, bring innocence to the altar." It is no wonder, then, if those who do not keep innocence, do not secure the effect of this sacrament.

Reply to Objection 3: That Christ is received under another species belongs to the nature of a sacrament, which acts instrumentally. But there is nothing to prevent an instrumental cause from producing a more mighty effect, as is evident from what was said above (Q[77], A[3], ad 3).

Objection 1: It seems that the forgiveness of mortal sin is an effect of this sacrament. For it is said in one of the Collects (Postcommunion, Pro vivis et defunctis): "May this sacrament be a cleansing from crimes." But mortal sins are called crimes. Therefore mortal sins are blotted out by this sacrament.

Objection 2: Further, this sacrament, like Baptism, works by the power of Christ's Passion. But mortal sins are forgiven by Baptism, as stated above (Q[69], A[1]). Therefore they are forgiven likewise by this sacrament, especially since in the form of this sacrament it is said: "Which shall be shed for many unto the forgiveness of sins."

Objection 3: Further, grace is bestowed through this sacrament, as stated above(A[1]). But by grace a man is justified from mortal sins, according to Rom. 3:24: "Being justified freely by His grace." Therefore mortal sins are forgiven by this sacrament.

On the contrary, It is written (1 Cor. 11:29): "He that eateth and drinketh unworthily, eateth and drinketh judgment to himself": and a gloss of the same passage makes the following commentary: "He eats and drinks unworthily who is in the state of sin, or who handles (the sacrament) 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 to Objection 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 to Objection 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 receives Christ within himself by way of spiritual nourishment, which is unbecoming to one that lies dead in his sins. Therefore the comparison does not hold good.

Reply to Objection 3: Grace is the sufficient cause of the forgiveness of mortal sin; yet it does not forgive sin except when it is first bestowed on the sinner. But it is not given so in this sacrament. Hence the argument does not prove.

Objection 1: It seems that venial sins are not forgiven by this sacrament, because this is the "sacrament of charity," as Augustine says (Tract. xxvi in Joan.). But venial sins are not contrary to charity, as was shown in the FS, Q[88], AA,2; SS, Q[24], A[10]. Therefore, since contrary is taken away by its contrary, it seems that venial sins are not forgiven by this sacrament.

Objection 2: Further, if venial sins be forgiven by this sacrament, then all of them are forgiven for the same reason as one is. But it does not appear that all are forgiven, because thus one might frequently be without any venial sin, against what is said in 1 Jn. 1:8: "If we say that we have no sin, we deceive ourselves." Therefore no venial sin is forgiven by this sacrament.

Objection 3: Further, contraries mutually exclude each other. But venial sins do not forbid the receiving of this sacrament: because Augustine says on the words, "If any man eat of it he shall [Vulg.: 'may'] not die for ever" (Jn. 6:50): "Bring innocence to the altar: your sins, though they be daily... let them not be deadly." Therefore neither are venial sins taken away by this sacrament.

On the contrary, Innocent III says (De S. Alt. Myst. iv) that this sacrament "blots out venial sins, and wards off mortal sins."

I answer that, Two things may be considered in this sacrament, to wit, the sacrament itself, and the reality of the sacrament: and it appears from both that this sacrament has the power of forgiving venial sins. For this sacrament is received under the form of nourishing food. Now nourishment from food is requisite for the body to make good the daily waste caused by the action of natural heat. But something is also lost daily of our spirituality from the heat of concupiscence through venial sins, which lessen the fervor of charity, as was shown in the SS, Q[24], A[10]. And therefore it belongs to this sacrament to forgive venial sins. Hence Ambrose says (De Sacram. v) that this daily bread is taken "as a remedy against daily infirmity."

The reality of this sacrament is charity, not only as to its habit, but also as to its act, which is kindled in this sacrament; and by this means venial sins are forgiven. Consequently, it is manifest that venial sins are forgiven by the power of this sacrament.

Reply to Objection 1: Venial sins, although not opposed to the habit of charity, are nevertheless opposed to the fervor of its act, which act is kindled by this sacrament; by reason of which act venial sins are blotted out.

Reply to Objection 1: The passage quoted is not to be understood as if a man could not at some time be without all guilt of venial sin: but that the just do not pass through this life without committing venial sins.

Reply to Objection 3: The power of charity, to which this sacrament belongs, is greater than that of venial sins: because charity by its act takes away venial sins, which nevertheless cannot entirely hinder the act of charity. And the same holds good of this sacrament.

Objection 1: It seems that the entire punishment due to sin is forgiven through this sacrament. For through this sacrament man receives the effect of Christ's Passion within himself as stated above (AA,2), just as he does through Baptism. But through Baptism man receives forgiveness of all punishment, through the virtue of Christ's Passion, which satisfied sufficiently for all sins, as was explained above (Q[69], A[2]). Therefore it seems the whole debt of punishment is forgiven through this sacrament.

Objection 2: Further, Pope Alexander I says (Ep. ad omnes orth.): "No sacrifice can be greater than the body and the blood of Christ." But man satisfied for his sins by the sacrifices of the old Law: for it is written (Lev. 4, 5): "If a man shall sin, let him offer" (so and so) "for his sin, and it shall be forgiven him." Therefore this sacrament avails much more for the forgiveness of all punishment.

Objection 3: Further, it is certain that some part of the debt of punishment is forgiven by this sacrament; for which reason it is sometimes enjoined upon a man, by way of satisfaction, to have masses said for himself. But if one part of the punishment is forgiven, for the same reason is the other forgiven: owing to Christ's infinite power contained in this sacrament. Consequently, it seems that the whole punishment can be taken away by this sacrament.

On the contrary, In that case no other punishment would have to be enjoined; just as none is imposed upon the newly baptized.

I answer that, This sacrament is both a sacrifice and a sacrament. it has the nature of a sacrifice inasmuch as it is offered up; and it has the nature of a sacrament inasmuch as it is received. And therefore it has the effect of a sacrament in the recipient, and the effect of a sacrifice in the offerer, or in them for whom it is offered.

If, then, it be considered as a sacrament, it produces its effect in two ways: first of all directly through the power of the sacrament; secondly as by a kind of concomitance, as was said above regarding what is contained in the sacrament (Q[76], AA,2). Through the power of the sacrament it produces directly that effect for which it was instituted. Now it was instituted not for satisfaction, but for nourishing spiritually through union between Christ and His members, as nourishment is united with the person nourished. But because this union is the effect of charity, from the fervor of which man obtains forgiveness, not only of guilt but also of punishment, hence it is that as a consequence, and by concomitance with the chief effect, man obtains forgiveness of the punishment, not indeed of the entire punishment, but according to the measure of his devotion and fervor.

But in so far as it is a sacrifice, it has a satisfactory power. Yet in satisfaction, the affection of the offerer is weighed rather than the quantity of the offering. Hence our Lord says (Mk. 12:43: cf. Lk. 21:4) of the widow who offered "two mites" that she "cast in more than all." Therefore, although this offering suffices of its own quantity to satisfy for all punishment, yet it becomes satisfactory for them for whom it is offered, or even for the offerers, according to the measure of their devotion, and not for the whole punishment.

Reply to Objection 1: The sacrament of Baptism is directly ordained for the remission of punishment and guilt: not so the Eucharist, because Baptism is given to man as dying with Christ, whereas the Eucharist is given as by way of nourishing and perfecting him through Christ. Consequently there is no parallel.

Reply to Objection 2: Those other sacrifices and oblations did not effect the forgiveness of the whole punishment, neither as to the quantity of the thing offered, as this sacrament does, nor as to personal devotion; from which it comes to pass that even here the whole punishment is not taken away.

Reply to Objection 3: If part of the punishment and not the whole be taken away by this sacrament, it is due to a defect not on the part of Christ's power, but on the part of man's devotion.
