Reply Obj. 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 princip[al] 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. _______________________

EIGHTH ARTICLE [III, Q. 60, Art. 8]

Whether It Is Lawful to Add Anything to the Words in Which the
Sacramental Form Consists?

Objection 1: It seems that it is not lawful to add anything to the words in which the sacramental form consists. For these sacramental words are not of less importance than are the words of Holy Scripture. But it is not lawful to add anything to, or to take anything from, the words of Holy Scripture: for it is written (Deut. 4:2): "You shall not add to the word that I speak to you, neither shall you take away from it"; and (Apoc. 22:18, 19): "I testify to everyone that heareth the words of the prophecy of this book: if any man shall add to these things, God shall add to him the plagues written in this book. And if any man shall take away . . . God shall take away his part out of the book of life." Therefore it seems that neither is it lawful to add anything to, or to take anything from, the sacramental forms.

Obj. 2: Further, in the sacraments words are by way of form, as stated above (A. 6, ad 2; A. 7). But any addition or subtraction in forms changes the species, as also in numbers (Metaph. viii). Therefore it seems that if anything be added to or subtracted from a sacramental form, it will not be the same sacrament.

Obj. 3: Further, just as the sacramental form demands a certain number of words, so does it require that these words should be pronounced in a certain order and without interruption. If therefore, the sacrament is not rendered invalid by addition or subtraction of words, in like manner it seems that neither is it, if the words be pronounced in a different order or with interruptions.

On the contrary, Certain words are inserted by some in the sacramental forms, which are not inserted by others: thus the Latins baptize under this form: "I baptize thee in the name of the Father, and of the Son, and of the Holy Ghost"; whereas the Greeks use the following form: "The servant of God, N . . . is baptized in the name of the Father," etc. Yet both confer the sacrament validly. Therefore it is lawful to add something to, or to take something from, the sacramental forms.

I answer that, With regard to all the variations that may occur in the sacramental forms, two points seem to call for our attention. One is on the part of the person who says the words, and whose intention is essential to the sacrament, as will be explained further on (Q. 64, A. 8). Wherefore if he intends by such addition or suppression to perform a rite other from that which is recognized by the Church, it seems that the sacrament is invalid: because he seems not to intend to do what the Church does.
