Argument: "Man" and "humanity" have the same meaning. Therefore it is rightly said that Christ is humanity.
Response: This is not conceded, but rather that Christ is man, because this is a concrete term with personal signification, whereas an abstract signifies the mode of nature, or naturally, so that therefore it is false that Christ is human nature, that is, humanity, or that Christ is humanity. Aristotle says that abstract terms refer to nature, and concrete terms to a person.
XII [a].
Argument: Whatever belongs [inest] to something, can be predicated of it. Humanity belongs to Christ. Therefore Christ is humanity.
Response: To "belong" is to inhere to a subject. Whiteness inheres to John. Therefore John is whiteness. But this does not follow in the abstract. But I concede it in the concrete: Whiteness inheres to John, therefore he is white. Humanity belongs to Christ, therefore he is a man.
