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.
_On the contrary,_ As long as a thing remains the same, it cannot at the same time be seen by the same eye under diverse species. But the glorified eye sees Christ always, as He is in His own species, according to Isa. 33:17: "(His eyes) shall see the king in his beauty." It seems, then, that it does not see Christ, as He is under the species of this sacrament.
_I answer that,_ The eye is of two kinds, namely, the bodily eye properly so-called, and the intellectual eye, so-called by similitude. But Christ's body as it is in this sacrament cannot be seen by any bodily eye. First of all, because a body which is visible brings about an alteration in the medium, through its accidents. Now the accidents of Christ's body are in this sacrament by means of the substance; so that the accidents of Christ's body have no immediate relationship either to this sacrament or to adjacent bodies; consequently they do not act on the medium so as to be seen by any corporeal eye. Secondly, because, as stated above (A. 1, ad 3; A. 3), Christ's body is substantially present in this sacrament. But substance, as such, is not visible to the bodily eye, nor does it come under any one of the senses, nor under the imagination, but solely under the intellect, whose object is "what a thing is" (De Anima iii). And therefore, properly speaking, Christ's body, according to the mode of being which it has in this sacrament, is perceptible neither by the sense nor by the imagination, but only by the intellect, which is called the spiritual eye.
Moreover it is perceived differently by different intellects. For since the way in which Christ is in this sacrament is entirely supernatural, it is visible in itself to a supernatural, i.e. the Divine, intellect, and consequently to a beatified intellect, of angel or of man, which, through the participated glory of the Divine intellect, sees all supernatural things in the vision of the Divine Essence. But it can be seen by a wayfarer through faith alone, like other supernatural things. And not even the angelic intellect of its own natural power is capable of beholding it; consequently the devils cannot by their intellect perceive Christ in this sacrament, except through faith, to which they do not pay willing assent; yet they are convinced of it from the evidence of signs, according to James 2:19: "The devils believe, and tremble."
Reply Obj. 1: Our bodily eye, on account of the sacramental species, is hindered from beholding the body of Christ underlying them, not merely as by way of veil (just as we are hindered from seeing what is covered with any corporeal veil), but also because Christ's body bears a relation to the medium surrounding this sacrament, not through its own accidents, but through the sacramental species.
Reply Obj. 2: Christ's own bodily eye sees Himself existing under the sacrament, yet it cannot see the way in which it exists under the sacrament, because that belongs to the intellect. But it is not the same with any other glorified eye, because Christ's eye is under this sacrament, in which no other glorified eye is conformed to it.
Reply Obj. 3: No angel, good or bad, can see anything with a bodily eye, but only with the mental eye. Hence there is no parallel reason, as is evident from what was said above.
EIGHTH ARTICLE [III, Q. 76, Art. 8] Whether Christ's Body Is Truly There When Flesh or a Child Appears Miraculously in This Sacrament?
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.
_On the contrary,_ When such apparition takes place, the same reverence is shown to it as was shown at first, which would not be done if Christ were not truly there, to Whom we show reverence of _latria._ Therefore, when such apparition occurs, Christ is under the sacrament.
_I answer that,_ Such apparition comes about in two ways, when occasionally in this sacrament flesh, or blood, or a child, is seen.
Sometimes it happens on the part of the beholders, whose eyes are so affected as if they outwardly saw flesh, or blood, or a child, while no change takes place in the sacrament. And this seems to happen when to one person it is seen under the species of flesh or of a child, while to others it is seen as before under the species of bread; or when to the same individual it appears for an hour under the appearance of flesh or a child, and afterwards under the appearance of bread. Nor is there any deception there, as occurs in the feats of magicians, because such species is divinely formed in the eye in order to represent some truth, namely, for the purpose of showing that Christ's body is truly under this sacrament; just as Christ without deception appeared to the disciples who were going to Emmaus.
For Augustine says (De Qq. Evang. ii) that "when our pretense is referred to some significance, it is not a lie, but a figure of the truth." And since in this way no change is made in the sacrament, it is manifest that, when such apparition occurs, Christ does not cease to be under this sacrament.
But it sometimes happens that such apparition comes about not merely by a change wrought in the beholders, but by an appearance which really exists outwardly. And this indeed is seen to happen when it is beheld by everyone under such an appearance, and it remains so not for an hour, but for a considerable time; and, in this case some think that it is the proper species of Christ's body. Nor does it matter that sometimes Christ's entire body is not seen there, but part of His flesh, or else that it is not seen in youthful guise, but in the semblance of a child, because it lies within the power of a glorified body for it to be seen by a non-glorified eye either entirely or in part, and under its own semblance or in strange guise, as will be said later (Suppl., Q. 85, AA. 2, 3).
But this seems unlikely. First of all, because Christ's body under its proper species can be seen only in one place, wherein it is definitively contained. Hence since it is seen in its proper species, and is adored in heaven, it is not seen under its proper species in this sacrament. Secondly, because a glorified body, which appears at will, disappears when it wills after the apparition; thus it is related (Luke 24:31) that our Lord "vanished out of sight" of the disciples. But that which appears under the likeness of flesh in this sacrament, continues for a long time; indeed, one reads of its being sometimes enclosed, and, by order of many bishops, preserved in a pyx, which it would be wicked to think of Christ under His proper semblance.
Consequently, it remains to be said, that, while the dimensions remain the same as before, there is a miraculous change wrought in the other accidents, such as shape, color, and the rest, so that flesh, or blood, or a child, is seen. And, as was said already, this is not deception, because it is done "to represent the truth," namely, to show by this miraculous apparition that Christ's body and blood are truly in this sacrament. And thus it is clear that as the dimensions remain, which are the foundation of the other accidents, as we shall see later on (Q. 77, A. 2), the body of Christ truly remains in this sacrament.
Reply Obj. 1: When such apparition takes place, the sacramental species sometimes continue entire in themselves; and sometimes only as to that which is principal, as was said above.
Reply Obj. 2: As stated above, during such apparitions Christ's proper semblance is not seen, but a species miraculously formed either in the eyes of the beholders, or in the sacramental dimensions themselves, as was said above.
Reply Obj. 3: The dimensions of the consecrated bread and wine continue, while a miraculous change is wrought in the other accidents, as stated above.
QUESTION 77 OF THE ACCIDENTS WHICH REMAIN IN THIS SACRAMENT (In Eight Articles) We must now consider the accidents which remain in this sacrament; under which head there are eight points of inquiry: (1) Whether the accidents which remain are without a subject?
(2) Whether dimensive quantity is the subject of the other accidents?
(3) Whether such accidents can affect an extrinsic body?
(4) Whether they can be corrupted?
(5) Whether anything can be generated from them?
(6) Whether they can nourish?
(7) Of the breaking of the consecrated bread?
(8) Whether anything can be mixed with the consecrated wine?
FIRST ARTICLE [III, Q. 77, Art. 1] Whether the Accidents Remain in This Sacrament Without a Subject?
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.
_On the contrary,_ Gregory says in an Easter Homily (Lanfranc, De Corp. et Sang. Dom. xx) that "the sacramental species are the names of those things which were there before, namely, of the bread and wine." Therefore since the substance of the bread and the wine does not remain, it seems that these species remain without a subject.
_I answer that,_ The species of the bread and wine, which are perceived by our senses to remain in this sacrament after consecration, are not subjected in the substance of the bread and wine, for that does not remain, as stated above (Q. 75, A. 2); nor in the substantial form, for that does not remain (Q. 75, A. 6), and if it did remain, "it could not be a subject," as Boethius declares (De Trin. i). Furthermore it is manifest that these accidents are not subjected in the substance of Christ's body and blood, because the substance of the human body cannot in any way be affected by such accidents; nor is it possible for Christ's glorious and impassible body to be altered so as to receive these qualities.
Now there are some who say that they are in the surrounding atmosphere as in a subject. But even this cannot be: in the first place, because atmosphere is not susceptive of such accidents.
Secondly, because these accidents are not where the atmosphere is, nay more, the atmosphere is displaced by the motion of these species.
Thirdly, because accidents do not pass from subject to subject, so that the same identical accident which was first in one subject be afterwards in another; because an accident is individuated by the subject; hence it cannot come to pass for an accident remaining identically the same to be at one time in one subject, and at another time in another. Fourthly, since the atmosphere is not deprived of its own accidents, it would have at the one time its own accidents and others foreign to it. Nor can it be maintained that this is done miraculously in virtue of the consecration, because the words of consecration do not signify this, and they effect only what they signify.
Therefore it follows that the accidents continue in this sacrament without a subject. This can be done by Divine power: for since an effect depends more upon the first cause than on the second, God Who is the first cause both of substance and accident, can by His unlimited power preserve an accident in existence when the substance is withdrawn whereby it was preserved in existence as by its proper cause, just as without natural causes He can produce other effects of natural causes, even as He formed a human body in the Virgin's womb, "without the seed of man" (Hymn for Christmas, First Vespers).
Reply Obj. 1: There is nothing to hinder the common law of nature from ordaining a thing, the contrary of which is nevertheless ordained by a special privilege of grace, as is evident in the raising of the dead, and in the restoring of sight to the blind: even thus in human affairs, to some individuals some things are granted by special privilege which are outside the common law. And so, even though it be according to the common law of nature for an accident to be in a subject, still for a special reason, according to the order of grace, the accidents exist in this sacrament without a subject, on account of the reasons given above (Q. 75, A. 5).
Reply Obj. 2: Since being is not a genus, then being cannot be of itself the essence of either substance or accident. Consequently, the definition of substance is not--"a being of itself without a subject," nor is the definition of accident--"a being in a subject"; but it belongs to the quiddity or essence of substance "to have existence not in a subject"; while it belongs to the quiddity or essence of accident "to have existence in a subject." But in this sacrament it is not in virtue of their essence that accidents are not in a subject, but through the Divine power sustaining them; and consequently they do not cease to be accidents, because neither is the definition of accident withdrawn from them, nor does the definition of substance apply to them.
Reply Obj. 3: These accidents acquired individual being in the substance of the bread and wine; and when this substance is changed into the body and blood of Christ, they remain in that individuated being which they possessed before, hence they are individual and sensible.
Reply Obj. 4: These accidents had no being of their own nor other accidents, so long as the substance of the bread and wine remained; but their subjects had _such_ being through them, just as snow is _white_ through whiteness. But after the consecration the accidents which remain have being; hence they are compounded of existence and essence, as was said of the angels, in the First Part (Q. 50, A. 2, ad 3); and besides they have composition of quantitative parts.
SECOND ARTICLE [III, Q. 77, Art. 2] Whether in This Sacrament the Dimensive Quantity of the Bread or Wine Is the Subject of the Other Accidents?
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.
_On the contrary,_ Qualities are divisible only accidentally, that is, by reason of the subject. But the qualities remaining in this sacrament are divided by the division of dimensive quantity, as is evident through our senses. Therefore, dimensive quantity is the subject of the accidents which remain in this sacrament.
_I answer that,_ It is necessary to say that the other accidents which remain in this sacrament are subjected in the dimensive quantity of the bread and wine that remains: first of all, because something having quantity and color and affected by other accidents is perceived by the senses; nor is sense deceived in such. Secondly, because the first disposition of matter is dimensive quantity, hence Plato also assigned "great" and "small" as the first differences of matter (Aristotle, _Metaph._ iv). And because the first subject is matter, the consequence is that all other accidents are related to their subject through the medium of dimensive quantity; just as the first subject of color is said to be the surface, on which account some have maintained that dimensions are the substances of bodies, as is said in _Metaph._ iii. And since, when the subject is withdrawn, the accidents remain according to the being which they had before, it follows that all accidents remain founded upon dimensive quantity.
Thirdly, because, since the subject is the principle of individuation of the accidents, it is necessary for what is admitted as the subject of some accidents to be somehow the principle of individuation: for it is of the very notion of an individual that it cannot be in several; and this happens in two ways. First, because it is not natural to it to be in any one; and in this way immaterial separated forms, subsisting of themselves, are also individuals of themselves.
Secondly, because a form, be it substantial or accidental, is naturally in someone indeed, not in several, as this whiteness, which is in this body. As to the first, matter is the principle of individuation of all inherent forms, because, since these forms, considered in themselves, are naturally in something as in a subject, from the very fact that one of them is received in matter, which is not in another, it follows that neither can the form itself thus existing be in another. As to the second, it must be maintained that the principle of individuation is dimensive quantity. For that something is naturally in another one solely, is due to the fact that that other is undivided in itself, and distinct from all others. But it is on account of quantity that substance can be divided, as is said in _Phys._ i. And therefore dimensive quantity itself is a particular principle of individuation in forms of this kind, namely, inasmuch as forms numerically distinct are in different parts of the matter. Hence also dimensive quantity has of itself a kind of individuation, so that we can imagine several lines of the same species, differing in position, which is included in the notion of this quantity; for it belongs to dimension for it to be "quantity having position" (Aristotle, Categor. iv), and therefore dimensive quantity can be the subject of the other accidents, rather than the other way about.
Reply Obj. 1: One accident cannot of itself be the subject of another, because it does not exist of itself. But inasmuch as an accident is received in another thing, one is said to be the subject of the other, inasmuch as one is received in a subject through another, as the surface is said to be the subject of color. Hence when God makes an accident to exist of itself, it can also be of itself the subject of another.
Reply Obj. 2: The other accidents, even as they were in the substance of the bread, were individuated by means of dimensive quantity, as stated above. And therefore dimensive quantity is the subject of the other accidents remaining in this sacrament, rather than conversely.
Reply Obj. 3: Rarity and density are particular qualities accompanying bodies, by reason of their having much or little matter under dimensions; just as all other accidents likewise follow from the principles of substance. And consequently, as the accidents are preserved by Divine power when the substance is withdrawn, so, when matter is withdrawn, the qualities which go with matter, such as rarity and density, are preserved by Divine power.
Reply Obj. 4: Mathematical quantity abstracts not from intelligible matter, but from sensible matter, as is said in _Metaph._ vii. But matter is termed sensible because it underlies sensible qualities.
And therefore it is manifest that the dimensive quantity, which remains in this sacrament without a subject, is not mathematical quantity.
THIRD ARTICLE [III, Q. 77, Art. 3] Whether the Species Remaining in This Sacrament Can Change External Objects?
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.
_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.
FOURTH ARTICLE [III, Q. 77, Art. 4] Whether the Sacramental Species Can Be Corrupted?
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.
_On the contrary,_ We perceive by our senses that the consecrated hosts become putrefied and corrupted.
_I answer that,_ Corruption is "movement from being into non-being" (Aristotle, _Phys._ v). Now it has been stated (A. 3) that the sacramental species retain the same being as they had before when the substance of the bread was present. Consequently, as the being of those accidents could be corrupted while the substance of the bread and wine was present, so likewise they can be corrupted now that the substance has passed away.
But such accidents could have been previously corrupted in two ways: in one way, of themselves; in another way, accidentally. They could be corrupted of themselves, as by alteration of the qualities, and increase or decrease of the quantity, not in the way in which increase or decrease is found only in animated bodies, such as the substances of the bread and wine are not, but by addition or division; for, as is said in _Metaph._ iii, one dimension is dissolved by division, and two dimensions result; while on the contrary, by addition, two dimensions become one. And in this way such accidents can be corrupted manifestly after consecration, because the dimensive quantity which remains can receive division and addition; and since it is the subject of sensible qualities, as stated above (A. 1), it can likewise be the subject of their alteration, for instance, if the color or the savor of the bread or wine be altered.
An accident can be corrupted in another way, through the corruption of its subject, and in this way also they can be corrupted after consecration; for although the subject does not remain, still the being which they had in the subject does remain, which being is proper, and suited to the subject. And therefore such being can be corrupted by a contrary agent, as the substance of the bread or wine was subject to corruption, and, moreover, was not corrupted except by a preceding alteration regarding the accidents.
Nevertheless, a distinction must be made between each of the aforesaid corruptions; because, when the body and the blood of Christ succeed in this sacrament to the substance of the bread and wine, if there be such change on the part of the accidents as would not have sufficed for the corruption of the bread and wine, then the body and blood of Christ do not cease to be under this sacrament on account of such change, whether the change be on the part of the quality, as for instance, when the color or the savor of the bread or wine is slightly modified; or on the part of the quantity, as when the bread or the wine is divided into such parts as to keep in them the nature of bread or of wine. But if the change be so great that the substance of the bread or wine would have been corrupted, then Christ's body and blood do not remain under this sacrament; and this either on the part of the qualities, as when the color, savor, and other qualities of the bread and wine are so altered as to be incompatible with the nature of bread or of wine; or else on the part of the quantity, as, for instance, if the bread be reduced to fine particles, or the wine divided into such tiny drops that the species of bread or wine no longer remain.
Reply Obj. 1: Since it belongs essentially to corruption to take away the being of a thing, in so far as the being of some form is in matter, it results that by corruption the form is separated from the matter. But if such being were not in matter, yet like such being as is in matter, it could be taken away by corruption, even where there is no matter; as takes place in this sacrament, as is evident from what was said above.
Reply Obj. 2: Although the sacramental species are forms not in matter, yet they have the being which they had in matter.
Reply Obj. 3: This corruption of species is not miraculous, but natural; nevertheless, it presupposes the miracle which is wrought in the consecration, namely, that those sacramental species retain without a subject, the same being as they had in a subject; just as a blind man, to whom sight is given miraculously, sees naturally.
FIFTH ARTICLE [III, Q. 77, Art. 5] Whether Anything Can Be Generated from the Sacramental Species?
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.
_On the contrary,_ The senses are witness that something is generated out of the sacramental species, either ashes, if they be burned, worms if they putrefy, or dust if they be crushed.
_I answer that,_ Since "the corruption of one thing is the generation of another" (De Gener. i), something must be generated necessarily from the sacramental species if they be corrupted, as stated above (A. 4); for they are not corrupted in such a way that they disappear altogether, as if reduced to nothing; on the contrary, something sensible manifestly succeeds to them.
Nevertheless, it is difficult to see how anything can be generated from them. For it is quite evident that nothing is generated out of the body and blood of Christ which are truly there, because these are incorruptible. But if the substance, or even the matter, of the bread and wine were to remain in this sacrament, then, as some have maintained, it would be easy to account for this sensible object which succeeds to them. But that supposition is false, as was stated Hence it is that others have said that the things generated have not sprung from the sacramental species, but from the surrounding atmosphere. But this can be shown in many ways to be impossible. In the first place, because when a thing is generated from another, the latter at first appears changed and corrupted; whereas no alteration or corruption appeared previously in the adjacent atmosphere; hence the worms or ashes are not generated therefrom. Secondly, because the nature of the atmosphere is not such as to permit of such things being generated by such alterations. Thirdly, because it is possible for many consecrated hosts to be burned or putrefied; nor would it be possible for an earthen body, large enough to be generated from the atmosphere, unless a great and, in fact, exceedingly sensible
