Augustine of Hippo

First comes in the natural body such as Adam was the first man to possess. Had he not sinned, he would never have died. Such a body we too possess, except that its nature as a result of sin has become so changed for the worse that it is now faced with inexorable death. Such a body Christ also deigned to assume for our sakes, not indeed by necessity but in virtue of his power. Afterward, however, comes the spiritual body such as that which Christ, our head, was the first to have been, but which we, his members, will have at the final resurrection of the dead.
