1. True: (A) Being human (having human nature) entails being a person, i.e., all persons that are human beings must have a human nature. This is what Dr. Michael Liccione says.
Christ Is A Human Person → Nestorianism
2. Christ is not a human person, because if Christ as man is a person, then we have the Nestorian blasphemy of two persons: God the Word and the man Jesus of Nazareth [Summa Theologica III, q. 16, art. 12, corp.]. Instead we confess that Jesus of Nazareth is an uncreated divine person with a human nature, and so He is a human being. For the divine “person subsisting in His human nature is” eternal and “not caused by the principles of the human nature” [ad 1].
4. (B) is false because then positing two natures in Christ (Dyophysitism) would entail two persons in Christ (Nestorianism). The ordo theologiae of the Nestorians is two natures → two persons, while the ordo theologiae of the Monophysites is one person → one nature.
