Q: Whether the Mixing with Water Is Essential to This Sacrament?

A: On the contrary,
Cyprian says (Ep. lxiii): "If any of our predecessors, out of ignorance or simplicity, has not kept this usage," i.e. of mixing water with the wine, "one may pardon his simplicity"; which would not be the case if water were essential to the sacrament, as the wine or the bread. Therefore the mingling of water with the wine is not essential to the sacrament.

I answer that,
Judgment concerning a sign is to be drawn from the thing signified. Now the adding of water to the wine is for the purpose of signifying the sharing of this sacrament by the faithful, in this respect that by the mixing of the water with the wine is signified the union of the people with Christ, as stated (A. 6). Moreover, the flowing of water from the side of Christ hanging on the cross refers to the same, because by the water is denoted the cleansing from sins, which was the effect of Christ's Passion. Now it was observed above (Q. 73, A. 1, ad 3), that this sacrament is completed in the consecration of the matter: while the usage of the faithful is not essential to the sacrament, but only a consequence thereof. Consequently, then, the adding of water is not essential to the sacrament.

Reply Obj. 1: Cyprian's expression is to be taken in the same sense in which we say that a thing cannot be, which cannot be suitably. And so the comparison refers to what ought to be done, not to what is essential to be done; since water is of the essence of bread, but not of the essence of wine.

Reply Obj. 2: The shedding of the blood belonged directly to Christ's Passion: for it is natural for blood to flow from a wounded human body. But the flowing of the water was not necessary for the Passion; but merely to show its effect, which is to wash away sins, and to refresh us from the heat of concupiscence. And therefore the water is not offered apart from the wine in this sacrament, as the wine is offered apart from the bread; but the water is offered mixed with the wine to show that the wine belongs of itself to this sacrament, as of its very essence; but the water as something added to the wine.

Reply Obj. 3: Since the mixing of water with the wine is not necessary for the sacrament, it does not matter, as to the essence of the sacrament, what kind of water is added to the wine, whether natural water, or artificial, as rose-water, although, as to the propriety of the sacrament, he would sin who mixes any other than natural and true water, because true water flowed from the side of Christ hanging on the cross, and not phlegm, as some have said, in order to show that Christ's body was truly composed of the four elements; as by the flowing blood, it was shown to be composed of the four humors, as Pope Innocent III says in a certain Decree. But because the mixing of water with flour is essential to this sacrament, as making the composition of bread, if rose-water, or any other liquor besides true water, be mixed with the flour, the sacrament would not be valid, because it would not be true bread.
Q: Objection 1: It seems that the mixing with water is essential to this sacrament. Because Cyprian says to Cecilius (Ep. lxiii): "Thus the Lord's chalice is not water only and wine only, but both must be mixed together: in the same way as neither the Lord's body be of flour only, except both," i.e. the flour and the water "be united as one." But the admixture of water with the flour is necessary for this sacrament. Consequently, for the like reason, so is the mixing of water with the wine.

Obj. 2: Further, at our Lord's Passion, of which this is the memorial, water as well as blood flowed from His side. But wine, which is the sacrament of the blood, is necessary for this sacrament. For the same reason, therefore, so is water.

Obj. 3: Further, if water were not essential to this sacrament, it would not matter in the least what kind of water was used; and so water distilled from roses, or any other kind might be employed; which is contrary to the usage of the Church. Consequently water is essential to this sacrament.
Q: Whether Water Should Be Added in Great Quantity?

A: On the contrary,
It is said in the Decretals (Extra, De Celeb. Miss.): "The pernicious abuse has prevailed in your country of adding water in greater quantity than the wine, in the sacrifice, where according to the reasonable custom of the entire Church more wine than water ought to be employed."

I answer that,
There is a threefold opinion regarding the water added to the wine, as Pope Innocent III says in a certain Decretal. For some say that the water remains by itself when the wine is changed into blood: but such an opinion cannot stand, because in the sacrament of the altar after the consecration there is nothing else save the body and the blood of Christ. Because, as Ambrose says in De Officiis (De Mysteriis ix): "Before the blessing it is another species that is named, after the blessing the Body is signified; otherwise it would not be adored with adoration of latria." And therefore others have said that as the wine is changed into blood, so the water is changed into the water which flowed from Christ's side. But this cannot be maintained reasonably, because according to this the water would be consecrated apart from the wine, as the wine is from the bread.

And therefore as he (Innocent III, Decretals, Extra, De Celeb. Miss.) says, the more probable opinion is that which holds that the water is changed into wine, and the wine into blood. Now, this could not be done unless so little water was used that it would be changed into wine. Consequently, it is always safer to add little water, especially if the wine be weak, because the sacrament could not be celebrated if there were such addition of water as to destroy the species of the wine. Hence Pope Julius I reprehends some who "keep throughout the year a linen cloth steeped in must, and at the time of sacrifice wash a part of it with water, and so make the offering."

Reply Obj. 1: For the signification of this sacrament it suffices for the water to be appreciable by sense when it is mixed with the wine: but it is not necessary for it to be sensible after the mingling.

Reply Obj. 2: If no water were added, the signification would be utterly excluded: but when the water is changed into wine, it is signified that the people is incorporated with Christ.

Reply Obj. 3: If water were added to a cask, it would not suffice for the signification of this sacrament, but the water must be added to the wine at the actual celebration of the sacrament.

QUESTION 75

OF THE CHANGE OF BREAD AND WINE INTO THE BODY AND BLOOD OF CHRIST (In Eight Articles)

We have to consider the change of the bread and wine into the body and blood of Christ; under which head there are eight points of inquiry:

(1) Whether the substance of bread and wine remain in this sacrament after the consecration?*

(2) Whether it is annihilated?

(3) Whether it is changed into the body and blood of Christ?

(4) Whether the accidents remain after the change?

(5) Whether the substantial form remains there?

(6) Whether this change is instantaneous?

(7) Whether it is more miraculous than any other change?

(8) By what words it may be suitably expressed?
Q: Objection 1: It seems that water ought to be added in great quantity, because as blood flowed sensibly from Christ's side, so did water: hence it is written (John 19:35): "He that saw it, hath given testimony." But water could not be sensibly present in this sacrament except it were used in great quantity. Consequently it seems that water ought to be added in great quantity.

Obj. 2: Further, a little water mixed with much wine is corrupted. But what is corrupted no longer exists. Therefore, it is the same thing to add a little water in this sacrament as to add none. But it is not lawful to add none. Therefore, neither is it lawful to add a little.

Obj. 3: Further, if it sufficed to add a little, then as a consequence it would suffice to throw one drop of water into an entire cask. But this seems ridiculous. Therefore it does not suffice for a small quantity to be added.
Q: Objection 1: It seems that the body of Christ is not in this sacrament in very truth, but only as in a figure, or sign. For it is written (John 6:54) that when our Lord had uttered these words: "Except you eat the flesh of the Son of Man, and drink His blood," etc., "Many of His disciples on hearing it said: 'this is a hard saying'": to whom He rejoined: "It is the spirit that quickeneth; the flesh profiteth nothing": as if He were to say, according to Augustine's exposition on Ps. 4 [*On Ps. 98:9]: "Give a spiritual meaning to what I have said. You are not to eat this body which you see, nor to drink the blood which they who crucify Me are to spill. It is a mystery that I put before you: in its spiritual sense it will quicken you; but the flesh profiteth nothing."

Obj. 2: Further, our Lord said (Matt. 28:20): "Behold I am with you all days even to the consummation of the world." Now in explaining this, Augustine makes this observation (Tract. xxx in Joan.): "The Lord is on high until the world be ended; nevertheless the truth of the Lord is here with us; for the body, in which He rose again, must be in one place; but His truth is spread abroad everywhere." Therefore, the body of Christ is not in this sacrament in very truth, but only as in a sign.

Obj. 3: Further, no body can be in several places at the one time. For this does not even belong to an angel; since for the same reason it could be everywhere. But Christ's is a true body, and it is in heaven. Consequently, it seems that it is not in very truth in the sacrament of the altar, but only as in a sign.

Obj. 4: Further, the Church's sacraments are ordained for the profit of the faithful. But according to Gregory in a certain Homily (xxviii in Evang.), the ruler is rebuked "for demanding Christ's bodily presence." Moreover the apostles were prevented from receiving the Holy Ghost because they were attached to His bodily presence, as Augustine says on John 16:7: "Except I go, the Paraclete will not come to you" (Tract. xciv in Joan.). Therefore Christ is not in the sacrament of the altar according to His bodily presence.
Q: Whether in This Sacrament the Substance of the Bread and Wine Remains After the Consecration?

A: On the contrary,
Ambrose says (De Sacram. iv): "Although the figure of the bread and wine be seen, still, after the Consecration, they are to be believed to be nothing else than the body end blood of Christ."

I answer that,
Some have held that the substance of the bread and wine remains in this sacrament after the consecration. But this opinion cannot stand: first of all, because by such an opinion the truth of this sacrament is destroyed, to which it belongs that Christ's true body exists in this sacrament; which indeed was not there before the consecration. Now a thing cannot be in any place, where it was not previously, except by change of place, or by the conversion of another thing into itself; just as fire begins anew to be in some house, either because it is carried thither, or because it is generated there. Now it is evident that Christ's body does not begin to be present in this sacrament by local motion. First of all, because it would follow that it would cease to be in heaven: for what is moved locally does not come anew to some place unless it quit the former one. Secondly, because every body moved locally passes through all intermediary spaces, which cannot be said here. Thirdly, because it is not possible for one movement of the same body moved locally to be terminated in different places at the one time, whereas the body of Christ under this sacrament begins at the one time to be in several places. And consequently it remains that Christ's body cannot begin to be anew in this sacrament except by change of the substance of bread into itself. But what is changed into another thing, no longer remains after such change. Hence the conclusion is that, saving the truth of this sacrament, the substance of the bread cannot remain after the consecration.

Secondly, because this position is contrary to the form of this sacrament, in which it is said: "This is My body," which would not be true if the substance of the bread were to remain there; for the substance of bread never is the body of Christ. Rather should one say in that case: "Here is My body."

Thirdly, because it would be opposed to the veneration of this sacrament, if any substance were there, which could not be adored with adoration of latria.

Fourthly, because it is contrary to the rite of the Church, according to which it is not lawful to take the body of Christ after bodily food, while it is nevertheless lawful to take one consecrated host after another. Hence this opinion is to be avoided as heretical.

Reply Obj. 1: God "wedded His Godhead," i.e. His Divine power, to the bread and wine, not that these may remain in this sacrament, but in order that He may make from them His body and blood.

Reply Obj. 2: Christ is not really present in the other sacraments, as in this; and therefore the substance of the matter remains in the other sacraments, but not in this.

Reply Obj. 3: The species which remain in this sacrament, as shall be said later (A. 5), suffice for its signification; because the nature of the substance is known by its accidents.
Q: Objection 1: It seems that the substance of the bread and wine does remain in this sacrament after the consecration: because Damascene says (De Fide Orth. iv): "Since it is customary for men to eat bread and drink wine, God has wedded his Godhead to them, and made them His body and blood": and further on: "The bread of communication is not simple bread, but is united to the Godhead." But wedding together belongs to things actually existing. Therefore the bread and wine are at the same time, in this sacrament, with the body and the blood of Christ.

Obj. 2: Further, there ought to be conformity between the sacraments. But in the other sacraments the substance of the matter remains, like the substance of water in Baptism, and the substance of chrism in Confirmation. Therefore the substance of the bread and wine remains also in this sacrament.

Obj. 3: Further, bread and wine are made use of in this sacrament, inasmuch as they denote ecclesiastical unity, as "one bread is made from many grains and wine from many grapes," as Augustine says in his book on the Creed (Tract. xxvi in Joan.). But this belongs to the substance of bread and wine. Therefore, the substance of the bread and wine remains in this sacrament.
Q: Objection 1: It seems that the substance of the bread is annihilated after the consecration of this sacrament, or dissolved into its original matter. For whatever is corporeal must be somewhere. But the substance of bread, which is something corporeal, does not remain, in this sacrament, as stated above (A. 2); nor can we assign any place where it may be. Consequently it is nothing after the consecration. Therefore, it is either annihilated, or dissolved into its original matter.

Obj. 2: Further, what is the term
wherefrom
in every change exists no longer, except in the potentiality of matter; e.g. when air is changed into fire, the form of the air remains only in the potentiality of matter; and in like fashion when what is white becomes black. But in this sacrament the substance of the bread or of the wine is the term
wherefrom,
while the body or the blood of Christ is the term "whereunto": for Ambrose says in De Officiis (De Myster. ix): "Before the blessing it is called another species, after the blessing the body of Christ is signified." Therefore, when the consecration takes place, the substance of the bread or wine no longer remains, unless perchance dissolved into its (original) matter.

Obj. 3: Further, one of two contradictories must be true. But this proposition is false: "After the consecration the substance of the bread or wine is something." Consequently, this is true: "The substance of the bread or wine is nothing."
Q: Whether Bread Can Be Converted into the Body of Christ?

A: On the contrary,
Eusebius Emesenus says: "To thee it ought neither to be a novelty nor an impossibility that earthly and mortal things be changed into the substance of Christ."

I answer that,
As stated above (A. 2), since Christ's true body is in this sacrament, and since it does not begin to be there by local motion, nor is it contained therein as in a place, as is evident from what was stated above (A. 1, ad 2), it must be said then that it begins to be there by conversion of the substance of bread into itself.

Yet this change is not like natural changes, but is entirely supernatural, and effected by God's power alone. Hence Ambrose says [(De Sacram. iv): "See how Christ's word changes nature's laws, as He wills: a man is not wont to be born save of man and woman: see therefore that against the established law and order a man is born of a Virgin": and] [*The passage in the brackets is not in the Leonine edition] (De Myster. iv): "It is clear that a Virgin begot beyond the order of nature: and what we make is the body from the Virgin. Why, then, do you look for nature's order in Christ's body, since the Lord Jesus was Himself brought forth of a Virgin beyond nature?" Chrysostom likewise (Hom. xlvii), commenting on John 6:64: "The words which I have spoken to you," namely, of this sacrament, "are spirit and life," says: i.e. "spiritual, having nothing carnal, nor natural consequence; but they are rent from all such necessity which exists upon earth, and from the laws here established."

For it is evident that every agent acts according as it is in act. But every created agent is limited in its act, as being of a determinate genus and species: and consequently the action of every created agent bears upon some determinate act. Now the determination of every thing in actual existence comes from its form. Consequently, no natural or created agent can act except by changing the form in something; and on this account every change made according to nature's laws is a formal change. But God is infinite act, as stated in the First Part (Q. 7, A. 1; Q. 26, A. 2); hence His action extends to the whole nature of being. Therefore He can work not only formal conversion, so that diverse forms succeed each other in the same subject; but also the change of all being, so that, to wit, the whole substance of one thing be changed into the whole substance of another. And this is done by Divine power in this sacrament; for the whole substance of the bread is changed into the whole substance of Christ's body, and the whole substance of the wine into the whole substance of Christ's blood. Hence this is not a formal, but a substantial conversion; nor is it a kind of natural movement: but, with a name of its own, it can be called "transubstantiation."
Q: Objection 1: It seems that bread cannot be converted into the body of Christ. For conversion is a kind of change. But in every change there must be some subject, which from being previously in potentiality is now in act. because as is said in
Phys.
iii: "motion is the act of a thing existing in potentiality." But no subject can be assigned for the substance of the bread and of the body of Christ, because it is of the very nature of substance for it "not to be in a subject," as it is said in
Praedic.
iii. Therefore it is not possible for the whole substance of the bread to be converted into the body of Christ.

Obj. 2: Further, the form of the thing into which another is converted, begins anew to inhere in the matter of the thing converted into it: as when air is changed into fire not already existing, the form of fire begins anew to be in the matter of the air; and in like manner when food is converted into non-pre-existing man, the form of the man begins to be anew in the matter of the food. Therefore, if bread be changed into the body of Christ, the form of Christ's body must necessarily begin to be in the matter of the bread, which is false. Consequently, the bread is not changed into the substance of Christ's body.

Obj. 3: Further, when two things are diverse, one never becomes the other, as whiteness never becomes blackness, as is stated in
Phys.
i. But since two contrary forms are of themselves diverse, as being the principles of formal difference, so two signate matters are of themselves diverse, as being the principles of material distinction. Consequently, it is not possible for this matter of bread to become this matter whereby Christ's body is individuated, and so it is not possible for this substance of bread to be changed into the substance of Christ's body.
Q: Whether the Accidents of the Bread and Wine Remain in This Sacrament After the Change?

A: On the contrary,
Augustine says in his book on the Sentences of Prosper (Lanfranc, De Corp. et Sang. Dom. xiii): "Under the species which we behold, of bread and wine, we honor invisible things, i.e. flesh and blood."

I answer that,
It is evident to sense that all the accidents of the bread and wine remain after the consecration. And this is reasonably done by Divine providence. First of all, because it is not customary, but horrible, for men to eat human flesh, and to drink blood. And therefore Christ's flesh and blood are set before us to be partaken of under the species of those things which are the more commonly used by men, namely, bread and wine. Secondly, lest this sacrament might be derided by unbelievers, if we were to eat our Lord under His own species. Thirdly, that while we receive our Lord's body and blood invisibly, this may redound to the merit of faith.

Reply Obj. 1: As is said in the book
De Causis,
an effect depends more on the first cause than on the second. And therefore by God's power, which is the first cause of all things, it is possible for that which follows to remain, while that which is first is taken away.

Reply Obj. 2: There is no deception in this sacrament; for the accidents which are discerned by the senses are truly present. But the intellect, whose proper object is substance as is said in
De Anima
iii, is preserved by faith from deception.

And this serves as answer to the third argument; because faith is not contrary to the senses, but concerns things to which sense does not reach.

Reply Obj. 4: This change has not properly a subject, as was stated above (A. 4, ad 1); nevertheless the accidents which remain have some resemblance of a subject.
Q: Objection 1: It seems that the accidents of the bread and wine do not remain in this sacrament. For when that which comes first is removed, that which follows is also taken away. But substance is naturally before accident, as is proved in
Metaph.
vii. Since, then, after consecration, the substance of the bread does not remain in this sacrament, it seems that its accidents cannot remain.

Obj. 2: Further, there ought not to be any deception in a sacrament of truth. But we judge of substance by accidents. It seems, then, that human judgment is deceived, if, while the accidents remain, the substance of the bread does not. Consequently this is unbecoming to this sacrament.

Obj. 3: Further, although our faith is not subject to reason, still it is not contrary to reason, but above it, as was said in the beginning of this work (I, Q. 1, A. 6, ad 2; A. 8). But our reason has its origin in the senses. Therefore our faith ought not to be contrary to the senses, as it is when sense judges that to be bread which faith believes to be the substance of Christ's body. Therefore it is not befitting this sacrament for the accidents of bread to remain subject to the senses, and for the substance of bread not to remain.

Obj. 4: Further, what remains after the change has taken place seems to be the subject of change. If therefore the accidents of the bread remain after the change has been effected, it seems that the accidents are the subject of the change. But this is impossible; for "an accident cannot have an accident" (Metaph. iii). Therefore the accidents of the bread and wine ought not to remain in this sacrament.
