Whether the grace of union was natural to the man Christ?

❌ Objection 1 : It would seem that the grace of union was not natural to the man Christ. For the union of the Incarnation did not take place in the nature, but in the Person, as was said above (Article [2]). Now a thing is denominated from its terminus. Therefore this grace ought rather to be called personal than natural.

❌ Objection 2 : Further, grace is divided against nature, even as gratuitous things, which are from God, are distinguished from natural things, which are from an intrinsic principle. But if things are divided in opposition to one another, one is not denominated by the other. Therefore the grace of Christ was not natural to Him.

❌ Objection 3 : Further, natural is that which is according to nature. But the grace of union is not natural to Christ in regard to the Divine Nature, otherwise it would belong to the other Persons; nor is it natural to Him according to the human nature, otherwise it would belong to all men, since they are of the same nature as He. Therefore it would seem that the grace of union is nowise natural to Christ.
