CCC 626

Since the "Author of life" who was killed is the same "living one [who has] risen", The divine person of the Son of God necessarily continued to possess his human soul and body, separated from each other by death: By the fact that at Chnst's death his soul was separated from his flesh, his one person is not itself divided into two persons; for the human body and soul of Christ have existed in the same way from the beginning of his earthly existence, in the divine person of the Word; and in death, although separated from each other, both remained with one and the same person of the Word. "You will not let your Holy One see corruption"
