Although He died as man, and His holy soul was separated from His unstained body, yet His Godhead remained inseparate from either body or soul. Yet was not the one Person divided into two; for as both body and soul had from the beginning an existence in the Person of the Word, so also had they in death. For neither soul nor body had ever a Person of their own, besides the Person of the Word.
