We are burdened with this corruptible body; but knowing that the cause of this burdensomeness is not the nature and substance of the body, but its corruption, we do not desire to be deprived of the body, but to be clothed with its immortality… If Adam had not sinned, he would not have been divested of his body, but would have been clothed upon (superinvested) with immortality and incorruption, that his mortal (body) might have been absorbed by life; that is, that he might have passed from his natural body to the spiritual body.
Augustine
