Context

“But this is proper to a Divine Person, on account of its infinity, that there should be a concourse of natures in it, not accidentally, but in subsistence. Reply Obj. 3: As was said above (Q. 2, A. 1) , the human nature constitutes a Divine Person, not simply, but forasmuch as the Person is denominated from such a nature. For human nature does not make the Son of Man to be simply, since He was from eternity, but only to be man. It is by the Divine Nature that a Divine Person is constituted simply. Hence the Divine Person is not said to assume the Divine Nature, but to assume the human nature. _______________________ SECOND ARTICLE” source
