Now nature cannot be the principle of resurrection, although resurrection terminates in the life of nature. For nature is the principle of movement in the thing wherein nature is---either the active principle, as in the movement of heavy and light bodies and in the natural alterations of animals---or the passive principle, as in the generation of simple bodies. The passive principle of natural generation is the natural passive potentiality which always has an active principle corresponding to it in nature, according to Metaphysics viii, 1: nor as to this does it matter whether the active principle in nature correspond to the passive principle in respect of its ultimate perfection, namely the form; or in respect of a disposition in virtue of which it demands the ultimate form, as in the generation of a man according to the teaching of faith, or in all other generations according to the opinions of Plato and Avicenna. But in nature there is no active principle of the resurrection, neither as regards the union of the soul with the body, nor as regards the disposition which is the demand for that union: since such a disposition cannot be produced by nature, except in a definite way by the process of generation from seed. Wherefore even granted a passive potentiality on the part of the body, or any kind of inclination to its union with the soul, it is not such as to suffice for the conditions of natural movement. Therefore the resurrection, strictly speaking, is miraculous and not natural except in a restricted sense, as we have explained.
Reply to Objection 1: Damascene is speaking of those things that are found in all individuals and are caused by the principles of nature. For supposing by a divine operation all men to be made white, or to be gathered together in one place, as happened at the time of the deluge, it would not follow that whiteness or existence in some particular place is a natural property of man.
Reply to Objection 2: From natural things one does not come by a demonstration of reason to know non-natural things, but by the induction of reason one may know something above nature, since the natural bears a certain resemblance to the supernatural. Thus the union of soul and body resembles the union of the soul with God by the glory of fruition, as the Master says (Sent. ii, D, 1): and in like manner the examples, quoted by the Apostle and Gregory, are confirmatory evidences of our faith in the resurrection.
Reply to Objection 3: This argument regards an operation which terminates in something that is not natural but contrary to nature. Such is not the resurrection, and hence the argument is not to the point.
Reply to Objection 4: The entire operation of nature is subordinate to the Divine operation, just as the working of a lower art is subordinate to the working of a higher art. Hence just as all the work of a lower art has in view an end unattainable save by the operation of the higher art that produces the form, or makes use of what has been made by art: so the last end which the whole expectation of nature has in view is unattainable by the operation of nature, and for which reason the attaining thereto is not natural.
Reply to Objection 5: Although there can be no natural movement terminating in a violent rest, there can be a non-natural movement terminating in a natural rest, as explained above.
