FIRST ARTICLE: WHETHER IT IS FITTING FOR A DIVINE PERSON TO ASSUME

Cajetan says the purport of this title is to show that the question of this article concerns the divine person as such, so far as we introduce a mental distinction between person and the divine nature.[659]

State of the question. It is apparent from the first two difficulties presented at the beginning of the article, namely, that there is no possibility of any addition to a divine person because this person is in Himself infinitely perfect. Also incommunicability belongs to the concept of person.

Conclusion. To assume a nature is most properly befitting to a person.

Authoritative proof. St. Augustine, who is quoting St. Fulgentius, says: "This God, that is, the Only-begotten One, took the form, that is, the nature of a servant to His own person."

Proof from reason. It may be expressed in syllogistic form as follows: The word "assume," which practically means to take to oneself, is both the principle and the term of an act. But only a person can be both the principle and term of an act. Therefore only a person can assume.

The other articles of this question will bring out more clearly the meaning of the adverb "most properly."

Proof of minor. It belongs to a person to act, for actions are attributed to supposita, and a person is that which by itself separately exists and acts. Moreover a person is the term of this assumption, because the union took place in the person and not in the nature.

Assumption is properly an action by which the human nature is drawn into the subsistence of the Son, so that it may subsist by this subsistence. Hence this action not only produces in the human nature of Christ a relation of dependence on the Word, but communicates to it the personality of the Word.

Reply to first objection. No addition is made to the divine person, who is infinite. But what is divine is united to man. Hence not God, but man is perfected.

Reply to second objection. "A divine person is said to be incommunicable inasmuch as it cannot be predicated of several supposita, but nothing prevents several things being predicated of the person.... But this is proper to a divine person, on account of its infinity, that there should be a concourse of natures in it, in subsistence."[660]

Doubt. Does the termination of another nature belong exclusively to a divine person, so that it would be repugnant to every created or creatable personality? Can an angel, for example, or a devil assume the human nature? Some thought that St. John the Baptist was an angel incarnate, and that Antichrist will be a devil incarnate.

Reply. It is the common teaching among theologians that no created person can assume a nature into union with its suppositum. So say Cajetan, Soto, Alvarez, Medina, Suarez, Vasquez, Billuart. The reason is that finite personality derives its limitation and species from the nature whose complement and term it is. Although subsistence is the mode and term of the nature, it does not specify the nature, but is specified by it. Thus we speak of the human personality, or of the angelic personality; hence it implies a contradiction for the same personality of one nature to terminate another. On the contrary, the divine personality because of its infinity, as St. Thomas says,[661] is above both genus and species and contains formally and eminently the power of all possible personalities.
