THIRD ARTICLE [III, Q. 66, Art. 3]

Whether Water Is the Proper Matter of Baptism?

Objection 1: It seems that water is not the proper matter of Baptism.

For Baptism, according to Dionysius (Eccl. Hier. v) and Damascene (De

Fide Orth. iv), has a power of enlightening. But enlightenment is a

special characteristic of fire. Therefore Baptism should be conferred

with fire rather than with water: and all the more since John the

Baptist said when foretelling Christ's Baptism (Matt. 3:11): "He

shall baptize you in the Holy Ghost and fire."

Obj. 2: Further, the washing away of sins is signified in Baptism.

But many other things besides water are employed in washing, such as

wine, oil, and such like. Therefore Baptism can be conferred with

these also; and consequently water is not the proper matter of

Baptism.

Obj. 3: Further, the sacraments of the Church flowed from the side of

Christ hanging on the cross, as stated above (Q. 62, A. 5). But not

only water flowed therefrom, but also blood. Therefore it seems that

Baptism can also be conferred with blood. And this seems to be more

in keeping with the effect of Baptism, because it is written (Apoc.

1:5): "(Who) washed us from our sins in His own blood."

Obj. 4: Further, as Augustine (cf. Master of the Sentences, iv, 3)

and Bede (Exposit. in Luc. iii, 21) say, Christ, by "the touch of His

most pure flesh, endowed the waters with a regenerating and cleansing

virtue." But all waters are not connected with the waters of the

Jordan which Christ touched with His flesh. Consequently it seems

that Baptism cannot be conferred with any water; and therefore water,

as such, is not the proper matter of Baptism.

Obj. 5: Further, if water, as such, were the proper matter of

Baptism, there would be no need to do anything to the water before

using it for Baptism. But in solemn Baptism the water which is used

for baptizing, is exorcized and blessed. Therefore it seems that

water, as such, is not the proper matter of Baptism.

_On the contrary,_ our Lord said (John 3:5): "Unless a man be born

again of water and the Holy Ghost, he cannot enter into the kingdom

of God."

_I answer that,_ By Divine institution water is the proper matter of

Baptism; and with reason. First, by reason of the very nature of

Baptism, which is a regeneration unto spiritual life. And this

answers to the nature of water in a special degree; wherefore seeds,

from which all living things, viz. plants and animals are generated,

are moist and akin to water. For this reason certain philosophers

held that water is the first principle of all things.

Secondly, in regard to the effects of Baptism, to which the

properties of water correspond. For by reason of its moistness it

cleanses; and hence it fittingly signifies and causes the cleansing

from sins. By reason of its coolness it tempers superfluous heat:

wherefore it fittingly mitigates the concupiscence of the fomes. By

reason of its transparency, it is susceptive of light; hence its

adaptability to Baptism as the "sacrament of Faith."

Thirdly, because it is suitable for the signification of the

mysteries of Christ, by which we are justified. For, as Chrysostom

says (Hom. xxv in Joan.) on John 3:5, "Unless a man be born again,"

etc., "When we dip our heads under the water as in a kind of tomb our

old man is buried, and being submerged is hidden below, and thence he

rises again renewed."

Fourthly, because by being so universal and abundant, it is a matter

suitable to our need of this sacrament: for it can easily be obtained

everywhere.

Reply Obj. 1: Fire enlightens actively. But he who is baptized does

not become an enlightener, but is enlightened by faith, which "cometh

by hearing" (Rom. 10:17). Consequently water is more suitable, than

fire, for Baptism.

But when we find it said: "He shall baptize you in the Holy Ghost and

fire," we may understand fire, as Jerome says (In Matth. ii), to mean

the Holy Ghost, Who appeared above the disciples under the form of

fiery tongues (Acts 2:3). Or we may understand it to mean

tribulation, as Chrysostom says (Hom. iii in Matth.): because

tribulation washes away sin, and tempers concupiscence. Or again, as

Hilary says (Super Matth. ii) that "when we have been baptized in the

Holy Ghost," we still have to be "perfected by the fire of the

judgment."

Reply Obj. 2: Wine and oil are not so commonly used for washing, as

water. Neither do they wash so efficiently: for whatever is washed

with them, contracts a certain smell therefrom; which is not the case

if water be used. Moreover, they are not so universal or so abundant

as water.

Reply Obj. 3: Water flowed from Christ's side to wash us; blood, to

redeem us. Wherefore blood belongs to the sacrament of the Eucharist,

while water belongs to the sacrament of Baptism. Yet this latter

sacrament derives its cleansing virtue from the power of Christ's

blood.

Reply Obj. 4: Christ's power flowed into all waters, by reason of,

not connection of place, but likeness of species, as Augustine says

in a sermon on the Epiphany (Append. Serm. cxxxv): "The blessing that

flowed from the Saviour's Baptism, like a mystic river, swelled the

course of every stream, and filled the channels of every spring."

Reply Obj. 5: The blessing of the water is not essential to Baptism,

but belongs to a certain solemnity, whereby the devotion of the

faithful is aroused, and the cunning of the devil hindered from

impeding the baptismal effect.
