Context

“And hence to be man is newly predicated of God without any change in Him, by a change in the human nature, which is assumed to a Divine Person. And hence, when it is said, "God was made man," we understand no change on the part of God, but only on the part of the human nature. Reply Obj. 3: Man stands not for the bare Person of the Son of God, but inasmuch as it subsists in human nature. Hence, although this is false, "God was made the Person of the Son of God," yet this is true: "God was made man" by being united to human nature. _______________________ SEVENTH ARTICLE [III, Q. 16, Art.” source
