Proslogium and Monologium/Monologium/Chapter30

Chapter XXX
This expression does not consist of more words than one, but is one Word.

Why, then, should I have any further doubt regarding that question which I dismissed above as doubtful, namely, whether this expression consists of more words than one, or of one? For, if it is so consubstantial with the supreme Nature that they are not two spirits, but one; assuredly, just as the latter is supremely simple, so is the former. It therefore does not consist of more words than one, but is one Word, through which all things were created.
