City of God, Book XIII
The truth is, that the Spirit of God taught His prophets so much of His will as He thought fit to reveal, but the philosophers, in their efforts to discover it, were deceived by human conjecture.
But they should not have been so led astray, I will not say by their ignorance, but by their obstinacy, as to contradict themselves so frequently; for they maintain, with all their vaunted might, that in order to the happiness of the soul, it must abandon not only its earthly body, but every kind of body. And yet they hold that the gods, whose souls are most blessed, are bound to everlasting bodies, the celestials to fiery bodies, and the soul of Jove himself (or this world, as they would have us believe) to all the physical elements which compose this entire mass reaching from earth to heaven. For this soul Plato believes to be extended and diffused by musical numbers, from the middle of the inside of the earth, which geometricians call the centre, outwards through all its parts to the utmost heights and extremities of the heavens; so that this world is a very great and blessed immortal animal, whose soul has both the perfect blessedness of wisdom, and never leaves its own body and whose body has life everlasting from the soul, and by no means clogs or hinders it, though itself be not a simple body, but compacted of so many and so huge materials. Since, therefore, they allow so much to their own conjectures, why do they refuse to believe that by the divine will and power immortality can be conferred on earthly bodies, in which the souls would be neither oppressed with the burden of them, nor separated from them by any death, but live eternally and blessedly? Do they not assert that their own gods so live in bodies of fire, and that Jove himself, their king, so lives in the physical elements? If, in order to its blessedness, the soul must quit every kind of body, let their gods flit from the starry spheres, and Jupiter from earth to sky; or, if they cannot do so, let them be pronounced miserable. But neither alternative will these men adopt. For, on the one hand, they dare not ascribe to their own gods a departure from the body, lest they should seem to worship mortals; on the other hand, they dare not deny their happiness, lest they should acknowledge wretches as gods. Therefore, to obtain blessedness, we need not quit every kind of body, but only the corruptible, cumbersome, painful, dying,—not such bodies as the goodness of God contrived for the first man, but such only as man’s sin entailed.
Chapter 18.—Of Earthly Bodies,
Which the Philosophers Affirm Cannot Be in Heavenly Places, Because Whatever is of Earth is by Its Natural Weight Attracted to Earth.
But it is necessary, they say, that the natural weight of earthly bodies either keeps them on earth or draws them to it; and therefore they cannot be in heaven. Our first parents were indeed on earth, in a well-wooded and fruitful spot, which has been named Paradise. But let our adversaries a little more carefully consider this subject of earthly weight, because it has important bearings, both on the ascension of the body of Christ, and also on the resurrection body of the saints. If human skill can by some contrivance fabricate vessels that float, out of metals which sink as soon as they are placed on the water, how much more credible is it that God, by some occult mode of operation, should even more certainly effect that these earthy masses be emancipated from the downward pressure of their weight? This cannot be impossible to that God by whose almighty will, according to Plato, neither things born perish, nor things composed dissolve, especially since it is much more wonderful that spiritual and bodily essences be conjoined than that bodies be adjusted to other material substances. Can we not also easily believe that souls, being made perfectly blessed, should be endowed with the power of moving their earthy but incorruptible bodies as they please, with almost spontaneous movement, and of placing them where they please with the readiest action? If the angels transport whatever terrestrial creatures they please from any place they please, and convey them whither they please, is it to be believed that they cannot do so without toil and the feeling of burden? Why, then, may we not believe that the spirits of the saints, made perfect and blessed by divine grace, can carry their own bodies where they please, and set them where they will? For, though we have been accustomed to notice, in bearing weights, that the larger the quantity the greater the weight of earthy bodies is, and that the greater the weight the more burdensome it is, yet the soul carries the members of its own flesh with less difficulty when they are massive with health, than in sickness when they are wasted. And though the hale and strong man feels heavier to other men carrying him than the lank and sickly, yet the man himself moves and carries his own body with less feeling of burden when he has the greater bulk of vigorous health, than when his frame is reduced to a minimum by hunger or disease. Of such consequence, in estimating the weight of earthly bodies, even while yet corruptible and mortal, is the consideration not of dead weight, but of the healthy equilibrium of the parts.
And what words can tell the difference between what we now call health and future immortality? Let not the philosophers, then, think to upset our faith with arguments from the weight of bodies; for I don’t care to inquire why they cannot believe an earthly body can be in heaven, while the whole earth is suspended on nothing. For perhaps the world keeps its central place by the same law that attracts to its centre all heavy bodies. But this I say, if the lesser gods, to whom Plato committed the creation of man and the other terrestrial creatures, were able, as he affirms, to withdraw from the fire its quality of burning, while they left it that of lighting, so that it should shine through the eyes; and if to the supreme God Plato also concedes the power of preserving from death things that have been born, and of preserving from dissolution things that are composed of parts so different as body and spirit;—are we to hesitate to concede to this same God the power to operate on the flesh of him whom He has endowed with immortality, so as to withdraw its corruption but leave its nature, remove its burdensome weight but retain its seemly form and members? But concerning our belief in the resurrection of the dead, and concerning their immortal bodies, we shall speak more at large, God willing, in the end of this work.
Chapter 19.—Against the Opinion of Those Who Do Not Believe that the Primitive Men Would Have Been Immortal If They Had Not Sinned.
At present let us go on, as we have begun, to give some explanation regarding the bodies of our first parents. I say then, that, except as the just consequence of sin, they would not have been subjected even to this death, which is good to the good,—this death, which is not exclusively known and believed in by a few, but is known to all, by which soul and body are separated, and by which the body of an animal which was but now visibly living is now visibly dead. For though there can be no manner of doubt that the souls of the just and holy dead live in peaceful rest, yet so much better would it be for them to be alive in healthy, well-conditioned bodies, that even those who hold the tenet that it is most blessed to be quit of every kind of body, condemn this opinion in spite of themselves. For no one will dare to set wise men, whether yet to die or already dead,—in other words, whether already quit of the body, or shortly to be so,—above the immortal gods, to whom the Supreme, in Plato, promises as a munificent gift life indissoluble, or in eternal union with their bodies. But this same Plato thinks that nothing better can happen to men than that they pass through life piously and justly, and, being separated from their bodies, be received into the bosom of the gods, who never abandon theirs; “that, oblivious of the past, they may revisit the upper air, and conceive the longing to return again to the body.” Virgil is applauded for borrowing this from the Platonic system. Assuredly Plato thinks that the souls of mortals cannot always be in their bodies, but must necessarily be dismissed by death; and, on the other hand, he thinks that without bodies they cannot endure for ever, but with ceaseless alternation pass from life to death, and from death to life. This difference, however, he sets between wise men and the rest, that they are carried after death to the stars, that each man may repose for a while in a star suitable for him, and may thence return to the labors and miseries of mortals when he has become oblivious of his former misery, and possessed with the desire of being embodied. Those, again, who have lived foolishly transmigrate into bodies fit for them, whether human or bestial. Thus he has appointed even the good and wise souls to a very hard lot indeed, since they do not receive such bodies as they might always and even immortally inhabit, but such only as they can neither permanently retain nor enjoy eternal purity without. Of this notion of Plato’s, we have in a former book already said that Porphyry was ashamed in the light of these Christian times, so that he not only emancipated human souls from a destiny in the bodies of beasts but also contended for the liberation of the souls of the wise from all bodily ties, so that, escaping from all flesh, they might, as bare and blessed souls, dwell with the Father time without end. And that he might not seem to be outbid by Christ’s promise of life everlasting to His saints, he also established purified souls in endless felicity, without return to their former woes; but, that he might contradict Christ, he denies the resurrection of incorruptible bodies, and maintains that these souls will live eternally, not only without earthly bodies, but without any bodies at all.
