Whether the soul was assumed before the flesh by the Son of God?

Objections

Objection 1 : It would seem that the soul of Christ was assumed before the flesh by the Word. For the Son of God assumed flesh through the medium of the soul, as was said above (Article [1]). Now the medium is reached before the end. Therefore the Son of God assumed the soul before the body.
Objection 2 : Further, the soul of Christ is nobler than the angels, according to Ps. 96:8: "Adore Him, all you His angels." But the angels were created in the beginning, as was said above (FP, Question [46], Article [3]). Therefore the soul of Christ also (was created in the beginning). But it was not created before it was assumed, for Damascene says (De Fide Orth. iii, 2,3,9), that "neither the soul nor the body of Christ ever had any hypostasis save the hypostasis of the Word." Therefore it would seem that the soul was assumed before the flesh, which was conceived in the womb of the Virgin.
Objection 3 : Further, it is written (Jn. 1:14): "We saw Him [Vulg.: 'His glory'] full of grace and truth," and it is added afterwards that "of His fulness we have all received" (Jn. 1:16), i.e. all the faithful of all time, as Chrysostom expounds it (Hom. xiii in Joan.). Now this could not have been unless the soul of Christ had all fulness of grace and truth before all the saints, who were from the beginning of the world, for the cause is not subsequent to the effect. Hence since the fulness of grace and truth was in the soul of Christ from union with the Word, according to what is written in the same place: "We saw His glory, the glory as it were of the Only-begotten of the Father, full of grace and truth," it would seem in consequence that from the beginning of the world the soul of Christ was assumed by the Word of God.
