Whether the Son of God ought to have assumed human nature in all individuals?

Objections

Objection 1 : It would seem that the Son of God ought to have assumed human nature in all individuals. For what is assumed first and by itself is human nature. But what belongs essentially to a nature belongs to all who exist in the nature. Therefore it was fitting that human nature should be assumed by the Word of God in all its supposita.
Objection 2 : Further, the Divine Incarnation proceeded from Divine Love; hence it is written (Jn. 3:16): "God so loved the world as to give His only-begotten Son." But love makes us give ourselves to our friends as much as we can, and it was possible for the Son of God to assume several human natures, as was said above (Question [3], Article [7]), and with equal reason all. Hence it was fitting for the Son of God to assume human nature in all its supposita.
Objection 3 : Further, a skilful workman completes his work in the shortest manner possible. But it would have been a shorter way if all men had been assumed to the natural sonship than for one natural Son to lead many to the adoption of sons, as is written Gal. 4:5 (cf. Heb. 2:10). Therefore human nature ought to have been assumed by God in all its supposita.
