FIFTH ARTICLE [III, Q. 75, Art. 5]

Whether the Accidents of the Bread and Wine Remain in This Sacrament

After the Change?

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.

_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.
