Q: Objection 1: It seems that the body of Christ, as it is in this sacrament, can be seen by the eye, at least by a glorified one. For our eyes are hindered from beholding Christ's body in this sacrament, on account of the sacramental species veiling it. But the glorified eye cannot be hindered by anything from seeing bodies as they are. Therefore, the glorified eye can see Christ's body as it is in this sacrament.

Obj. 2: Further, the glorified bodies of the saints will be "made like to the body" of Christ's "glory," according to Phil. 3:21. But Christ's eye beholds Himself as He is in this sacrament. Therefore, for the same reason, every other glorified eye can see Him.

Obj. 3: Further, in the resurrection the saints will be equal to the angels, according to Luke 20:36. But the angels see the body of Christ as it is in this sacrament, for even the devils are found to pay reverence thereto, and to fear it. Therefore, for like reason, the glorified eye can see Christ as He is in this sacrament.
Q: Objection 1: It seems that Christ's body is not truly there when flesh or a child appears miraculously in this sacrament. Because His body ceases to be under this sacrament when the sacramental species cease to be present, as stated above (A. 6). But when flesh or a child appears, the sacramental species cease to be present. Therefore Christ's body is not truly there.

Obj. 2: Further, wherever Christ's body is, it is there either under its own species, or under those of the sacrament. But when such apparitions occur, it is evident that Christ is not present under His own species, because the entire Christ is contained in this sacrament, and He remains entire under the form in which He ascended to heaven: yet what appears miraculously in this sacrament is sometimes seen as a small particle of flesh, or at times as a small child. Now it is evident that He is not there under the sacramental species, which is that of bread or wine. Consequently, it seems that Christ's body is not there in any way.

Obj. 3: Further, Christ's body begins to be in this sacrament by consecration and conversion, as was said above (Q. 75, AA. 2, 3, 4). But the flesh and blood which appear by miracle are not consecrated, nor are they converted into Christ's true body and blood. Therefore the body or the blood of Christ is not under those species.
Q: Objection 1: It seems that the accidents do not remain in this sacrament without a subject, because there ought not to be anything disorderly or deceitful in this sacrament of truth. But for accidents to be without a subject is contrary to the order which God established in nature; and furthermore it seems to savor of deceit, since accidents are naturally the signs of the nature of the subject. Therefore the accidents are not without a subject in this sacrament.

Obj. 2: Further, not even by miracle can the definition of a thing be severed from it, or the definition of another thing be applied to it; for instance, that, while man remains a man, he can be an irrational animal. For it would follow that contradictories can exist at the one time: for the "definition of a thing is what its name expresses," as is said in
Metaph.
iv. But it belongs to the definition of an accident for it to be in a subject, while the definition of substance is that it must subsist of itself, and not in another. Therefore it cannot come to pass, even by miracle, that the accidents exist without a subject in this sacrament.

Obj. 3: Further, an accident is individuated by its subject. If therefore the accidents remain in this sacrament without a subject, they will not be individual, but general, which is clearly false, because thus they would not be sensible, but merely intelligible.

Obj. 4: Further, the accidents after the consecration of this sacrament do not obtain any composition. But before the consecration they were not composed either of matter and form, nor of existence (
quo est
) and essence ( quod est ). Therefore, even after consecration they are not composite in either of these ways. But this is unreasonable, for thus they would be simpler than angels, whereas at the same time these accidents are perceptible to the senses. Therefore, in this sacrament the accidents do not remain without a subject.
Q: Objection 1: It seems that in this sacrament the dimensive quantity of the bread or wine is not the subject of the other accidents. For accident is not the subject of accident; because no form can be a subject, since to be a subject is a property of matter. But dimensive quantity is an accident. Therefore dimensive quantity cannot be the subject of the other accidents.

Obj. 2: Further, just as quantity is individuated by substance, so also are the other accidents. If, then, the dimensive quantity of the bread or wine remains individuated according to the being it had before, in which it is preserved, for like reason the other accidents remain individuated according to the existence which they had before in the substance. Therefore they are not in dimensive quantity as in a subject, since every accident is individuated by its own subject.

Obj. 3: Further, among the other accidents that remain, of the bread and wine, the senses perceive also rarity and density, which cannot be in dimensive quantity existing outside matter; because a thing is rare which has little matter under great dimensions, while a thing is dense which has much matter under small dimensions, as is said in
Phys.
iv. It does not seem, then, that dimensive quantity can be the subject of the accidents which remain in this sacrament.

Obj. 4: Further, quantity abstract from matter seems to be mathematical quantity, which is not the subject of sensible qualities. Since, then, the remaining accidents in this sacrament are sensible, it seems that in this sacrament they cannot be subjected in the dimensive quantity of the bread and wine that remains after consecration.
Q: Whether the Species Remaining in This Sacrament Can Change External Objects?

A: On the contrary,
If they could not change external bodies, they could not be felt; for a thing is felt from the senses being changed by a sensible thing, as is said in De Anima ii.

I answer that,
Because everything acts in so far as it is an actual being, the consequence is that everything stands in the same relation to action as it does to being. Therefore, because, according to what was said above (A. 1), it is an effect of the Divine power that the sacramental species continue in the being which they had when the substance of the bread and wine was present, it follows that they continue in their action. Consequently they retain every action which they had while the substance of the bread and wine remained, now that the substance of the bread and wine has passed into the body and blood of Christ. Hence there is no doubt but that they can change external bodies.

Reply Obj. 1: The sacramental species, although they are forms existing without matter, still retain the same being which they had before in matter, and therefore as to their being they are like forms which are in matter.

Reply Obj. 2: The action of an accidental form depends upon the action of a substantial form in the same way as the being of accident depends upon the being of substance; and therefore, as it is an effect of Divine power that the sacramental species exist without substance, so is it an effect of Divine power that they can act without a substantial form, because every action of a substantial or accidental form depends upon God as the first agent.

Reply Obj. 3: The change which terminates in a substantial form is not effected by a substantial form directly, but by means of the active and passive qualities, which act in virtue of the substantial form. But by Divine power this instrumental energy is retained in the sacramental species, just as it was before: and consequently their action can be directed to a substantial form instrumentally, just in the same way as anything can act outside its species, not as by its own power, but by the power of the chief agent.
Q: Objection 1: It seems that the species which remain in this sacrament cannot affect external objects. For it is proved in
Phys.
vii, that forms which are in matter are produced by forms that are in matter, but not from forms which are without matter, because like makes like. But the sacramental species are species without matter, since they remain without a subject, as is evident from what was said above (A. 1). Therefore they cannot affect other matter by producing any form in it.

Obj. 2: Further, when the action of the principal agent ceases, then the action of the instrument must cease, as when the carpenter rests, the hammer is moved no longer. But all accidental forms act instrumentally in virtue of the substantial form as the principal agent. Therefore, since the substantial form of the bread and wine does not remain in this sacrament, as was shown above (Q. 75, A. 6), it seems that the accidental forms which remain cannot act so as to change external matter.

Obj. 3: Further, nothing acts outside its species, because an effect cannot surpass its cause. But all the sacramental species are accidents. Therefore they cannot change external matter, at least as to a substantial form.
Q: Objection 1: It seems that the sacramental species cannot be corrupted, because corruption comes of the separation of the form from the matter. But the matter of the bread does not remain in this sacrament, as is clear from what was said above (Q. 75, A. 2). Therefore these species cannot be corrupted.

Obj. 2: Further, no form is corrupted except accidentally, that is, when its subject is corrupted; hence self-subsisting forms are incorruptible, as is seen in spiritual substances. But the sacramental species are forms without a subject. Therefore they cannot be corrupted.

Obj. 3: Further, if they be corrupted, it will either be naturally or miraculously. But they cannot be corrupted naturally, because no subject of corruption can be assigned as remaining after the corruption has taken place. Neither can they be corrupted miraculously, because the miracles which occur in this sacrament take place in virtue of the consecration, whereby the sacramental species are preserved: and the same thing is not the cause of preservation and of corruption. Therefore, in no way can the sacramental species be corrupted.
Q: Objection 1: It seems that nothing can be generated from the sacramental species: because, whatever is generated, is generated out of some matter: for nothing is generated out of nothing, although by creation something is made out of nothing. But there is no matter underlying the sacramental species except that of Christ's body, and that body is incorruptible. Therefore it seems that nothing can be generated from the sacramental species.

Obj. 2: Further, things which are not of the same genus cannot spring from one another: thus a line is not made of whiteness. But accident and substance differ generically. Therefore, since the sacramental species are accidents, it seems that no substance can be generated from them.

Obj. 3: Further, if any corporeal substance be generated from them, such substance will not be without accident. Therefore, if any corporeal substance be generated from the sacramental species, then substance and accident would be generated from accident, namely, two things from one, which is impossible. Consequently, it is impossible for any corporeal substance to be generated out of the sacramental species.
Q: Whether the Sacramental Species Can Nourish?

A: On the contrary,
The Apostle speaking of this sacrament says (1 Cor. 11:21): "One, indeed, is hungry, and another is drunk": upon which the gloss observes that "he alludes to those who after the celebration of the sacred mystery, and after the consecration of the bread and wine, claimed their oblations, and not sharing them with others, took the whole, so as even to become intoxicated thereby." But this could not happen if the sacramental species did not nourish. Therefore the sacramental species do nourish.

I answer that,
This question presents no difficulty, now that we have solved the preceding question. Because, as stated in
De Anima
ii, food nourishes by being converted into the substance of the individual nourished. Now it has been stated (A. 5) that the sacramental species can be converted into a substance generated from them. And they can be converted into the human body for the same reason as they can into ashes or worms. Consequently, it is evident that they nourish.

But the senses witness to the untruth of what some maintain; viz. that the species do not nourish as though they were changed into the human body, but merely refresh and hearten by acting upon the senses (as a man is heartened by the odor of meat, and intoxicated by the fumes of wine). Because such refreshment does not suffice long for a man, whose body needs repair owing to constant waste: and yet a man could be supported for long if he were to take hosts and consecrated wine in great quantity.

In like manner the statement advanced by others cannot stand, who hold that the sacramental species nourish owing to the remaining substantial form of the bread and wine: both because the form does not remain, as stated above (Q. 75, A. 6): and because to nourish is the act not of a form but rather of matter, which takes the form of the one nourished, while the form of the nourishment passes away: hence it is said in
De Anima
ii that nourishment is at first unlike, but at the end is like.

Reply Obj. 1: After the consecration bread can be said to be in this sacrament in two ways. First, as to the species, which retain the name of the previous substance, as Gregory says in an Easter Homily (Lanfranc, De Corp. et Sang. Dom. xx). Secondly, Christ's very body can be called bread, since it is the mystical bread "coming down from heaven." Consequently, Ambrose uses the word "bread" in this second meaning, when he says that "this bread does not pass into the body," because, to wit, Christ's body is not changed into man's body, but nourishes his soul. But he is not speaking of bread taken in the first acceptation.

Reply Obj. 2: Although the sacramental species are not those things out of which the human body is made, yet they are changed into those things stated above.

Reply Obj. 3: Although the sacramental species are not a substance, still they have the virtue of a substance, as stated above.
Q: Objection 1: It seems that the sacramental species cannot nourish, because, as Ambrose says (De Sacram. v), "it is not this bread that enters into our body, but the bread of everlasting life, which supports the substance of our soul." But whatever nourishes enters into the body. Therefore this bread does not nourish: and the same reason holds good of the wine.

Obj. 2: Further, as is said in De Gener. ii, "We are nourished by the very things of which we are made." But the sacramental species are accidents, whereas man is not made of accidents, because accident is not a part of substance. Therefore it seems that the sacramental species cannot nourish.

Obj. 3: Further, the Philosopher says (De Anima ii) that "food nourishes according as it is a substance, but it gives increase by reason of its quantity." But the sacramental species are not a substance. Consequently they cannot nourish.
Q: Whether the Sacramental Species Are Broken in This Sacrament?

A: On the contrary,
Breaking arises from the division of that which has quantity. But nothing having quantity except the sacramental species is broken here, because neither Christ's body is broken, as being incorruptible, nor is the substance of the bread, because it no longer remains. Therefore the sacramental species are broken.

I answer that,
Many opinions prevailed of old on this matter. Some held that in this sacrament there was no breaking at all in reality, but merely in the eyes of the beholders. But this contention cannot stand, because in this sacrament of truth the sense is not deceived with regard to its proper object of judgment, and one of these objects is breaking, whereby from one thing arise many: and these are common sensibles, as is stated in
De Anima
ii.

Others accordingly have said that there was indeed a genuine breaking, but without any subject. But this again contradicts our senses; because a quantitative body is seen in this sacrament, which formerly was one, and is now divided into many, and this must be the subject of the breaking.

But it cannot be said that Christ's true body is broken. First of all, because it is incorruptible and impassible: secondly, because it is entire under every part, as was shown above (Q. 76, A. 3), which is contrary to the nature of a thing broken.

It remains, then, that the breaking is in the dimensive quantity of the bread, as in a subject, just as the other accidents. And as the sacramental species are the sacrament of Christ's true body, so is the breaking of these species the sacrament of our Lord's Passion, which was in Christ's true body.

Reply Obj. 1: As rarity and density remain under the sacramental species, as stated above (A. 2, ad 3), so likewise porousness remains, and in consequence breakableness.

Reply Obj. 2: Hardness results from density; therefore, as density remains under the sacramental species, hardness remains there too, and the capability of sound as a consequence.

Reply Obj. 3: What is eaten under its own species, is also broken and masticated under its own species; but Christ's body is eaten not under its proper, but under the sacramental species. Hence in explaining John 6:64, "The flesh profiteth nothing," Augustine (Tract. xxvii in Joan.) says that this is to be taken as referring to those who understood carnally: "for they understood the flesh, thus, as it is divided piecemeal, in a dead body, or as sold in the shambles." Consequently, Christ's very body is not broken, except according to its sacramental species. And the confession made by Berengarius is to be understood in this sense, that the breaking and the crushing with the teeth is to be referred to the sacramental species, under which the body of Christ truly is.
Q: Objection 1: It seems that the sacramental species are not broken in this sacrament, because the Philosopher says in Meteor. iv that bodies are breakable owing to a certain disposition of the pores; a thing which cannot be attributed to the sacramental species. Therefore the sacramental species cannot be broken.

Obj. 2: Further, breaking is followed by sound. But the sacramental species emit no sound: because the Philosopher says (De Anima ii), that what emits sound is a hard body, having a smooth surface. Therefore the sacramental species are not broken.

Obj. 3: Further, breaking and mastication are seemingly of the same object. But it is Christ's true body that is eaten, according to John 6:57: "He that eateth My flesh, and drinketh My blood." Therefore it is Christ's body that is broken and masticated: and hence it is said in the confession of Berengarius: "I agree with the Holy Catholic Church, and with heart and lips I profess, that the bread and wine which are placed on the altar, are the true body and blood of Christ after consecration, and are truly handled and broken by the priest's hands, broken and crushed by the teeth of believers." Consequently, the breaking ought not to be ascribed to the sacramental species.
Q: Objection 1: It seems that no liquid can be mingled with the consecrated wine, because everything mingled with another partakes of its quality. But no liquid can share in the quality of the sacramental species, because those accidents are without a subject, as stated above (A. 1). Therefore it seems that no liquid can be mingled with the sacramental species of the wine.

Obj. 2: Further, if any kind of liquid be mixed with those species, then some one thing must be the result. But no one thing can result from the liquid, which is a substance, and the sacramental species, which are accidents; nor from the liquid and Christ's blood, which owing to its incorruptibility suffers neither increase nor decrease. Therefore no liquid can be mixed with the consecrated wine.

Obj. 3: Further, if any liquid be mixed with the consecrated wine, then that also would appear to be consecrated; just as water added to holy-water becomes holy. But the consecrated wine is truly Christ's blood. Therefore the liquid added would likewise be Christ's blood otherwise than by consecration, which is unbecoming. Therefore no liquid can be mingled with the consecrated wine.

Obj. 4: Further, if one of two things be entirely corrupted, there is no mixture (De Gener. i). But if we mix any liquid, it seems that the entire species of the sacramental wine is corrupted, so that the blood of Christ ceases to be beneath it; both because great and little are difference of quantity, and alter it, as white and black cause a difference of color; and because the liquid mixed, as having no obstacle, seems to permeate the whole, and so Christ's blood ceases to be there, since it is not there with any other substance. Consequently, no liquid can be mixed with the consecrated wine.
Q: Objection 1: It seems that this is not the form of this sacrament: "This is My body," and, "This is the chalice of My blood." Because those words seem to belong to the form of this sacrament, wherewith Christ consecrated His body and blood. But Christ first blessed the bread which He took, and said afterwards: "Take ye and eat; this is My body" (Matt. 26:26). Therefore the whole of this seems to belong to the form of this sacrament: and the same reason holds good of the words which go with the consecration of the blood.

Obj. 2: Further, Eusebius Emissenus (Pseudo-Hieron: Ep. xxix; Pseudo-Isid.: Hom. iv) says: "The invisible Priest changes visible creatures into His own body, saying: 'Take ye and eat; this is My body.'" Therefore, the whole of this seems to belong to the form of this sacrament: and the same hold good of the works appertaining to the blood.

Obj. 3: Further, in the form of Baptism both the minister and his act are expressed, when it is said, "I baptize thee." But in the words set forth above there is no mention made either of the minister or of his act. Therefore the form of the sacrament is not a suitable one.

Obj. 4: Further, the form of the sacrament suffices for its perfection; hence the sacrament of Baptism can be performed sometimes by pronouncing the words of the form only, omitting all the others. Therefore, if the aforesaid words be the form of this sacrament, it would seem as if this sacrament could be performed sometimes by uttering those words alone, while leaving out all the others which are said in the mass; yet this seems to be false, because, were the other words to be passed over, the said words would be taken as spoken in the person of the priest saying them, whereas the bread and wine are not changed into his body and blood. Consequently, the aforesaid words are not the form of this sacrament.
