Whether words are required for the signification of the sacraments?
Objection 1: It seems that words are not required for the signification of the sacraments. For Augustine says (Contra Faust. xix): "What else is a corporeal sacrament but a kind of visible word?" Wherefore to add words to the sensible things in the sacraments seems to be the same as to add words to words. But this is superfluous. Therefore words are not required besides the sensible things in the sacraments .
Objection 2: Further, a sacrament is some one thing, but it does not seem possible to make one thing of those that belong to different genera. Since, therefore, sensible things and words are of different genera, for sensible things are the product of nature, but words, of reason; it seems that in the sacraments, words are not required besides sensible things.
Objection 3: Further, the sacraments of the New Law succeed those of the Old Law: since "the former were instituted when the latter were abolished," as Augustine says (Contra Faust. xix). But no form of words was required in the sacraments of the Old Law. Therefore neither is it required in those of the New Law.
On the contrary, The Apostle says (Eph. 5:25,26): "Christ loved the Church, and delivered Himself up for it; that He might sanctify it, cleansing it by the laver of water in the word of life." And Augustine says (Tract. xxx in Joan.): "The word is added to the element, and this becomes a sacrament."
I answer that, The sacraments, as stated above (AA 2,3), are employed as signs for man's sanctification. Consequently they can be considered in three ways: and in each way it is fitting for words to be added to the sensible signs. For in the first place they can be considered in regard to the cause of sanctification, which is the Word incarnate: to Whom the sacraments have a certain conformity, in that the word is joined to the sensible sign, just as in the mystery of the Incarnation the Word of God is united to sensible flesh.
Secondly, sacraments may be considered on the part of man who is sanctified, and who is composed of soul and body: to whom the sacramental remedy is adjusted, since it touches the body through the sensible element, and the soul through faith in the words. Hence Augustine says (Tract. lxxx in Joan.) on Jn. 15:3, "Now you are clean by reason of the word," etc.: "Whence hath water this so great virtue, to touch the body and wash the heart, but by the word doing it, not because it is spoken, but because it is believed?"
Thirdly, a sacrament may be considered on the part of the sacramental signification. Now Augustine says (De Doctr. Christ. ii) that "words are the principal signs used by men"; because words can be formed in various ways for the purpose of signifying various mental concepts, so that we are able to express our thoughts with greater distinctness by means of words. And therefore in order to insure the perfection of sacramental signification it was necessary to determine the signification of the sensible things by means of certain words. For water may signify both a cleansing by reason of its humidity, and refreshment by reason of its being cool: but when we say, "I baptize thee," it is clear that we use water in baptism in order to signify a spiritual cleansing.
Reply to Objection 1: The sensible elements of the sacraments are called words by way of a certain likeness, in so far as they partake of a certain significative power, which resides principally in the very words, as stated above. Consequently it is not a superfluous repetition to add words to the visible element in the sacraments; because one determines the other, as stated above.
Reply to Objection 2: Although words and other sensible things are not in the same genus, considered in their natures, yet have they something in common as to the thing signified by them: which is more perfectly done in words than in other things. Wherefore in the sacraments, words and things, like form and matter, combine in the formation of one thing, in so far as the signification of things is completed by means of words, as above stated. And under words are comprised also sensible actions, such as cleansing and anointing and such like: because they have a like signification with the things.
Reply to Objection 3: As Augustine says (Contra Faust. xix), the sacraments of things present should be different from sacraments of things to come. Now the sacraments of the Old Law foretold the coming of Christ. Consequently they did not signify Christ so clearly as the sacraments of the New Law, which flow from Christ Himself, and have a certain likeness to Him, as stated above. Nevertheless in the Old Law, certain words were used in things pertaining to the worship of God, both by the priests, who were the ministers of those sacraments, according to Num. 6:23,24: "Thus shall you bless the children of Israel, and you shall say to them: The Lord bless thee," etc.; and by those who made use of those sacraments, according to Dt. 26:3: "I profess this day before the Lord thy God," etc.
III · Q. 60, Art. 7: Whether determinate words are required in the sacraments?
Whether determinate words are required in the sacraments?
Objection 1: It seems that determinate words are not required in the sacraments. For as the Philosopher says (Peri Herm. i), "words are not the same for all." But salvation, which is sought through the sacraments, is the same for all. Therefore determinate words are not required in the sacraments.
Objection 2: Further, words are required in the sacraments forasmuch as they are the principal means of signification, as stated above (A 6). But it happens that various words mean the same. Therefore determinate words are not required in the sacraments.
Objection 3: Further, corruption of anything changes its species. But some corrupt the pronunciation of words, and yet it is not credible that the sacramental effect is hindered thereby; else unlettered men and stammerers, in conferring sacraments, would frequently do so invalidly. Therefore it seems that determinate words are not required in the sacraments.
On the contrary, our Lord used determinate words in consecrating the sacrament of the Eucharist, when He said (Mat. 26:26): "This is My Body." Likewise He commanded His disciples to baptize under a form of determinate words, saying (Mat. 28:19): "Go ye and teach all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Ghost."
I answer that, As stated above (A 6, ad 2), in the sacraments the words are as the form, and sensible things are as the matter. Now in all things composed of matter and form, the determining principle is on the part of the form, which is as it were the end and terminus of the matter. Consequently for the being of a thing the need of a determinate form is prior to the need of determinate matter: for determinate matter is needed that it may be adapted to the determinate form. Since, therefore, in the sacraments determinate sensible things are required, which are as the sacramental matter, much more is there need in them of a determinate form of words.
Reply to Objection 1: As Augustine says (Tract. lxxx super Joan.), the word operates in the sacraments "not because it is spoken," i.e. not by the outward sound of the voice, "but because it is believed" in accordance with the sense of the words which is held by faith. And this sense is indeed the same for all, though the same words as to their sound be not used by all. Consequently no matter in what language this sense is expressed, the sacrament is complete.
Reply to Objection 2: Although it happens in every language that various words signify the same thing, yet one of those words is that which those who speak that language use principally and more commonly to signify that particular thing: and this is the word which should be used for the sacramental signification. So also among sensible things, that one is used for the sacramental signification which is most commonly employed for the action by which the sacramental effect is signified: thus water is most commonly used by men for bodily cleansing, by which the spiritual cleansing is signified: and therefore water is employed as the matter of baptism.
Reply to Objection 3: If he who corrupts the pronunciation of the sacramental words---does so on purpose, he does not seem to intend to do what the Church intends: and thus the sacrament seems to be defective. But if he do this through error or a slip of the tongue, and if he so far mispronounce the words as to deprive them of sense, the sacrament seems to be defective. This would be the case especially if the mispronunciation be in the beginning of a word, for instance, if one were to say "in nomine matris" instead of "in nomine Patris." If, however, the sense of the words be not entirely lost by this mispronunciation, the sacrament is complete. This would be the case principally if the end of a word be mispronounced; for instance, if one were to say "patrias et filias." For although the words thus mispronounced have no appointed meaning, yet we allow them an accommodated meaning corresponding to the usual forms of speech. And so, although the sensible sound is changed, yet the sense remains the same.
What has been said about the various mispronunciations of words, either at the beginning or at the end, holds forasmuch as with us a change at the beginning of a word changes the meaning, whereas a change at the end generally speaking does not effect such a change: whereas with the Greeks the sense is changed also in the beginning of words in the conjugation of verbs.
Nevertheless the principle point to observe is the extent of the corruption entailed by mispronunciation: for in either case it may be so little that it does not alter the sense of the words; or so great that it destroys it. But it is easier for the one to happen on the part of the beginning of the words, and the other at the end.
