SECOND ARTICLE [III, Q. 74, Art. 2]

Whether a Determinate Quantity of Bread and Wine Is Required for the

Matter of This Sacrament?

Objection 1: It seems that a determinate quantity of bread and wine

is required for the matter of this sacrament. Because the effects of

grace are no less set in order than those of nature. But, "there is a

limit set by nature upon all existing things, and a reckoning of size

and development" (De Anima ii). Consequently, in this sacrament,

which is called "Eucharist," that is, "a good grace," a determinate

quantity of the bread and wine is required.

Obj. 2: Further, Christ gave no power to the ministers of the Church

regarding matters which involve derision of the faith and of His

sacraments, according to 2 Cor. 10:8: "Of our power which the Lord

hath given us unto edification, and not for your destruction." But it

would lead to mockery of this sacrament if the priest were to wish to

consecrate all the bread which is sold in the market and all the wine

in the cellar. Therefore he cannot do this.

Obj. 3: Further, if anyone be baptized in the sea, the entire

sea-water is not sanctified by the form of baptism, but only the

water wherewith the body of the baptized is cleansed. Therefore,

neither in this sacrament can a superfluous quantity of bread be

consecrated.

_On the contrary,_ Much is opposed to little, and great to small. But

there is no quantity, however small, of the bread and wine which

cannot be consecrated. Therefore, neither is there any quantity,

however great, which cannot be consecrated.

_I answer that,_ Some have maintained that the priest could not

consecrate an immense quantity of bread and wine, for instance, all

the bread in the market or all the wine in a cask. But this does not

appear to be true, because in all things containing matter, the

reason for the determination of the matter is drawn from its

disposition to an end, just as the matter of a saw is iron, so as to

adapt it for cutting. But the end of this sacrament is the use of the

faithful. Consequently, the quantity of the matter of this sacrament

must be determined by comparison with the use of the faithful. But

this cannot be determined by comparison with the use of the faithful

who are actually present; otherwise the parish priest having few

parishioners could not consecrate many hosts. It remains, then, for

the matter of this sacrament to be determined in reference to the

number of the faithful absolutely. But the number of the faithful is

not a determinate one. Hence it cannot be said that the quantity of

the matter of this sacrament is restricted.

Reply Obj. 1: The matter of every natural object has its determinate

quantity by comparison with its determinate form. But the number of

the faithful, for whose use this sacrament is ordained, is not a

determinate one. Consequently there is no comparison.

Reply Obj. 2: The power of the Church's ministers is ordained for two

purposes: first for the proper effect, and secondly for the end of

the effect. But the second does not take away the first. Hence, if

the priest intends to consecrate the body of Christ for an evil

purpose, for instance, to make mockery of it, or to administer poison

through it, he commits sin by his evil intention, nevertheless, on

account of the power committed to him, he accomplishes the sacrament.

Reply Obj. 3: The sacrament of Baptism is perfected in the use of the

matter: and therefore no more of the water is hallowed than what is

used. But this sacrament is wrought in the consecration of the

matter. Consequently there is no parallel.
