Whether the union of the two natures in Christ is the greatest of all unions?

Objections

Objection 1 : It would seem that the union of the two natures in Christ is not the greatest of all unions. For what is united falls short of the unity of what is one, since what is united is by participation, but one is by essence. Now in created things there are some that are simply one, as is shown especially in unity itself, which is the principle of number. Therefore the union of which we are speaking does not imply the greatest of all unions.
Objection 2 : Further, the greater the distance between things united, the less the union. Now, the things united by this union are most distant---namely, the Divine and human natures; for they are infinitely apart. Therefore their union is the least of all.
Objection 3 : Further, from union there results one. But from the union of soul and body in us there arises what is one in person and nature; whereas from the union of the Divine and human nature there results what is one in person only. Therefore the union of soul and body is greater than that of the Divine and human natures; and hence the union of which we speak does not imply the greatest unity.
