Augustine of Hippo

Should anyone say that the cause of vices and evil habits lies in the flesh because when the soul is influenced by the flesh it lives in such a manner, he cannot have sufficiently considered human nature as a whole.… But notice that the apostle who, in discussing the corruptible body, had used the words "even though our outer man is decaying," goes on, a little further, to declare: "For we know that if the earthly house in which we dwell be destroyed, we have a building from God, a house not made by human hands, eternal in the heavens." … On the one hand, our corruptible body may be a burden on our soul; on the other hand, the cause of this encumbrance is not in the nature and substance of the body. Therefore, aware as we are of its corruption, we do not desire to be divested of the body but rather to be clothed with its immortality. In immortal life we shall have a body, but it will no longer be a burden since it will no longer be corruptible.
