On the Beginning of the World, and Its Causes
1 The next subject of inquiry is, whether there was any other world before the one which now exists; and if so, whether it was such as the present, or somewhat different, or inferior; or whether there was no world at all, but something like that which we understand will be after the end of all things, when the kingdom shall be delivered up to God, even the Father; which nevertheless may have been the end of another world—of that, namely, after which this world took its beginning; and whether the various lapses of intellectual natures provoked God to produce this diverse and varying condition of the world. This point also, I think, must be investigated in a similar way, viz., whether after this world there will be any (system of) preservation and amendment, severe indeed, and attended with much pain to those who were unwilling to obey the word of God, but a process through which, by means of instruction and rational training, those may arrive at a fuller understanding of the truth who have devoted themselves in the present life to these pursuits, and who, after having had their minds purified, have advanced onwards so as to become capable of attaining divine wisdom; and after this the end of all things will immediately follow, and there will be again, for the correction and improvement of those who stand in need of it, another world, either resembling that which now exists, or better than it, or greatly inferior; and how long that world, whatever it be that is to come after this, shall continue; and if there will be a time when no world shall anywhere exist, or if there has been a time when there was no world at all; or if there have been, or will be several; or if it shall ever come to pass that there will be one resembling another, like it in every respect, and indistinguishable from it.
2. That it may appear more clearly, then, whether bodily matter can exist during intervals of time, and whether, as it did not exist before it was made, so it may again be resolved into non-existence, let us see, first of all, whether it is possible for any one to live without a body. For if one person can live without a body, all things also may dispense with them; seeing our former treatise has shown that all things tend towards one end. Now, if all things may exist without bodies, there will undoubtedly be no bodily substance, seeing there will be no use for it. But how shall we understand the words of the apostle in those passages, in which, discussing the resurrection of the dead, he says, “This corruptible must put on incorruption, and this mortal must put on immortality. When this corruptible shall have put on incorruption, and this mortal shall have put on immortality, then shall be brought to pass the saying which is written, Death is swallowed up in victory! Where, O death, is your victory? O death, your sting has been swallowed up: the sting of death is sin, and the strength of sin is the law.” Some such meaning, then, as this, seems to be suggested by the apostle. For can the expression which he employs, “this corruptible,” and “this mortal,” with the gesture, as it were, of one who touches or points out, apply to anything else than to bodily matter? This matter of the body, then, which is now corruptible shall put on incorruption when a perfect soul, and one furnished with the marks of incorruption, shall have begun to inhabit it. And do not be surprised if we speak of a perfect soul as the clothing of the body (which, on account of the Word of God and His wisdom, is now named incorruption), when Jesus Christ Himself, who is the Lord and Creator of the soul, is said to be the clothing of the saints, according to the language of the apostle, “Put on the Lord Jesus Christ.” As Christ, then, is the clothing of the soul, so for a kind of reason sufficiently intelligible is the soul said to be the clothing of the body, seeing it is an ornament to it, covering and concealing its mortal nature. The expression, then, “This corruptible must put on incorruption,” is as if the apostle had said, “This corruptible nature of the body must receive the clothing of incorruption— a soul possessing in itself incorruptibility,” because it has been clothed with Christ, who is the Wisdom and Word of God. But when this body, which at some future period we shall possess in a more glorious state, shall have become a partaker of life, it will then, in addition to being immortal, become also incorruptible. For whatever is mortal is necessarily also corruptible; but whatever is corruptible cannot also be said to be mortal. We say of a stone or a piece of wood that it is corruptible, but we do not say that it follows that it is also mortal. But as the body partakes of life, then because life may be, and is, separated from it, we consequently name it mortal, and according to another sense also we speak of it as corruptible. The holy apostle therefore, with remarkable insight, referring to the general first cause of bodily matter, of which (matter), whatever be the qualities with which it is endowed (now indeed carnal, but by and by more refined and pure, which are termed spiritual), the soul makes constant use, says, “This corruptible must put on incorruption.” And in the second place, looking to the special cause of the body, he says, “This mortal must put on immortality.” Now, what else will incorruption and immortality be, save the wisdom, and the word, and the righteousness of God, which mould, and clothe, and adorn the soul? And hence it happens that it is said, “The corruptible will put on incorruption, and the mortal immortality.” For although we may now make great proficiency, yet as we only know in part, and prophesy in part, and see through a glass, darkly, those very things which we seem to understand, this corruptible does not yet put on incorruption, nor is this mortal yet clothed with immorality; and as this training of ours in the body is protracted doubtless to a longer period, up to the time, viz., when those very bodies of ours with which we are enveloped may, on account of the word of God, and His wisdom and perfect righteousness, earn incorruptibility and immortality, therefore is it said, “This corruptible must put on incorruption, and this mortal must put on immortality.”
3. But, nevertheless, those who think that rational creatures can at any time lead an existence out of the body, may here raise such questions as the following. If it is true that this corruptible shall put on incorruption, and this mortal put on immortality, and that death is swallowed up at the end; this shows that nothing else than a material nature is to be destroyed, on which death could operate, while the mental acumen of those who are in the body seems to be blunted by the nature of corporeal matter. If, however, they are out of the body, then they will altogether escape the annoyance arising from a disturbance of that kind. But as they will not be able immediately to escape all bodily clothing, they are just to be considered as inhabiting more refined and purer bodies, which possess the property of being no longer overcome by death, or of being wounded by its sting; so that at last, by the gradual disappearance of the material nature, death is both swallowed up, and even at the end exterminated, and all its sting completely blunted by the divine grace which the soul has been rendered capable of receiving, and has thus deserved to obtain incorruptibility and immortality. And then it will be deservedly said by all, “O death, where is your victory? O death, where is your sting? The sting of death is sin.” If these conclusions, then, seem to hold good, it follows that we must believe our condition at some future time to be incorporeal; and if this is admitted, and all are said to be subjected to Christ, this (incorporeity) also must necessarily be bestowed on all to whom the subjection to Christ extends; since all who are subject to Christ will be in the end subject to God the Father, to whom Christ is said to deliver up the kingdom; and thus it appears that then also the need of bodies will cease. And if it ceases, bodily matter returns to nothing, as formerly also it did not exist.
