Whether the whole human nature was assumed through the medium of the parts?

❌ Objection 1 : It would seem that the Son of God assumed the whole human nature through the medium of its parts. For Augustine says (De Agone Christ. xviii) that "the invisible and unchangeable Truth assumed the soul through the medium of the spirit, and the body through the medium of the soul, and in this way the whole man." But the spirit, soul, and body are parts of the whole man. Therefore He assumed all, through the medium of the parts.

❌ Objection 2 : Further, the Son of God assumed flesh through the medium of the soul because the soul is more like to God than the body. But the parts of human nature, since they are simpler than the body, would seem to be more like to God, Who is most simple, than the whole. Therefore He assumed the whole through the medium of the parts.

❌ Objection 3 : Further, the whole results from the union of parts. But the union is taken to be the term of the assumption, and the parts are presupposed to the assumption. Therefore He assumed the whole by the parts.
