Argument: A word is not a person. Christ is the Word. Therefore Christ is not a person.
I prove the major premise, that a word and a person are different.
Response: This is a new expression, which was formerly unheard of in the world. Christ is not a mathematical or physical word, but a divine and uncreated word, which signifies a substance and a person, because the divine Word is the divinity. Christ is the divine Word. Therefore he is the divinity, that is, a substantial person [ipsa substantia et persona]. Philosophically, "word" means a sound or an utterance, but speaking theologically, "Word" signifies the Son of God. This, Aristotle would not admit, that "Word" signifies true God [plenum Deum].
