Whether the union of the Incarnate Word took place in the Person?

❌ Objection 1 : It would seem that the union of the Incarnate Word did not take place in the person. For the Person of God is not distinct from His Nature, as we said (FP, Question [39], Article [1]). If, therefore, the union did not take place in the nature, it follows that it did not take place in the person.

❌ Objection 2 : Further, Christ's human nature has no less dignity than ours. But personality belongs to dignity, as was stated above (FP, Question [29], Article [3], ad 2). Hence, since our human nature has its proper personality, much more reason was there that Christ's should have its proper personality.

❌ Objection 3 : Further, as Boethius says (De Duab. Nat.), a person is an individual substance of rational nature. But the Word of God assumed an individual human nature, for "universal human nature does not exist of itself, but is the object of pure thought," as Damascene says (De Fide Orth. iii, 11). Therefore the human nature of Christ has its personality. Hence it does not seem that the union took place in the person.
