FIFTH ARTICLE: WHETHER EACH OF THE DIVINE PERSONS COULD HAVE ASSUMED HUMAN NATURE

State of the question. The difficulty is, as stated in the second objection, that by the divine Incarnation, men acquired the adoption of sons, which is a participated likeness of natural sonship, which applies only to the Son. Therefore it seems that only the Son could be incarnate. Moreover, to be incarnate is to be sent, which cannot apply to the Father, who cannot be sent by any person, since the other two persons proceed from Him.

Reply. Nevertheless it is affirmed, that each of the persons could have assumed human nature. For to assume another nature is befitting to God because of His omnipotence, as the principle of the assumption, and because of His person, as the term of the assumption. But each of the divine persons is omnipotent and has His own personality. Therefore each of the divine persons could have assumed human nature.

Reply to first objection. It was fitting, if the Father became incarnate, for Him as man to have been the Son of man, for example, the son of David; for this would be according to difference of natures, and would not result in confusion of realities, but at most of names.

Reply to second objection. It contains a beautiful scriptural text concerning adoptive sonship, which is a certain participated likeness of natural sonship. But if the Father became incarnate, we would have received this adoptive sonship from Him, as coming from the principle of natural sonship;[674] but farther on in this question, it is shown that it was more fitting for the Son to have become incarnate.[675]

Reply to third objection. The Father, who is innascible as to eternal birth, could have been born temporally as man if He had become incarnate. In such case the Incarnation would not have been a mission. Thus the Father dwells in the just, as the Son and the Holy Ghost do, but He is not sent, and so He comes without being sent; whereas the other two persons are sent by Him. So the pope sends His legate, but he himself is not sent, but comes.
