Whether "Word" is the Son's proper name?

Objections

Objection 1 : It would seem that "Word" is not the proper name of the Son. For the Son is a subsisting person in God. But word does not signify a subsisting thing, as appears in ourselves. Therefore word cannot be the proper name of the person of the Son.
Objection 2 : Further, the word proceeds from the speaker by being uttered. Therefore if the Son is properly the word, He proceeds from the Father, by way only of utterance; which is the heresy of Valentine; as appears from Augustine (De Haeres. xi).
Objection 3 : Further, every proper name of a person signifies some property of that person. Therefore, if the Word is the Son's proper name, it signifies some property of His; and thus there will be several more properties in God than those above mentioned.
Objection 4 : Further, whoever understands conceives a word in the act of understanding. But the Son understands. Therefore some word belongs to the Son; and consequently to be Word is not proper to the Son.
Objection 5 : Further, it is said of the Son (Heb. 1:3): "Bearing all things by the word of His power;" whence Basil infers (Cont. Eunom. v, 11) that the Holy Ghost is the Son's Word. Therefore to be Word is not proper to the Son.
