On the Resurrection, and the Judgment, the Fire of Hell, and Punishments
3 We now turn our attention to some of our own (believers), who, either from feebleness of intellect or want of proper instruction, adopt a very low and abject view of the resurrection of the body. We ask these persons in what manner they understand that an animal body is to be changed by the grace of the resurrection, and to become a spiritual one; and how that which is sown in weakness will arise in power; how that which is planted in dishonour will arise in glory; and that which was sown in corruption, will be changed to a state of incorruption. Because if they believe the apostle, that a body which arises in glory, and power, and incorruptibility, has already become spiritual, it appears absurd and contrary to his meaning to say that it can again be entangled with the passions of flesh and blood, seeing the apostle manifestly declares that “flesh and blood shall not inherit the kingdom of God, nor shall corruption inherit incorruption.” But how do they understand the declaration of the apostle, “We shall all be changed?” This transformation certainly is to be looked for, according to the order which we have taught above; and in it, undoubtedly, it becomes us to hope for something worthy of divine grace; and this we believe will take place in the order in which the apostle describes the sowing in the ground of a “bare grain of grain, or of any other fruit,” to which “God gives a body as it pleases Him,” as soon as the grain of grain is dead. For in the same way also our bodies are to be supposed to fall into the earth like a grain; and (that germ being implanted in them which contains the bodily substance) although the bodies die, and become corrupted, and are scattered abroad, yet by the word of God, that very germ which is always safe in the substance of the body, raises them from the earth, and restores and repairs them, as the power which is in the grain of wheat, after its corruption and death, repairs and restores the grain into a body having stalk and ear. And so also to those who shall deserve to obtain an inheritance in the kingdom of heaven, that germ of the body's restoration, which we have before mentioned, by God's command restores out of the earthly and animal body a spiritual one, capable of inhabiting the heavens; while to each one of those who may be of inferior merit, or of more abject condition, or even the lowest in the scale, and altogether thrust aside, there is yet given, in proportion to the dignity of his life and soul, a glory and dignity of body—nevertheless in such a way, that even the body which rises again of those who are to be destined to everlasting fire or to severe punishments, is by the very change of the resurrection so incorruptible, that it cannot be corrupted and dissolved even by severe punishments. If, then, such be the qualities of that body which will arise from the dead, let us now see what is the meaning of the threatening of eternal fire.
4. We find in the prophet Isaiah, that the fire with which each one is punished is described as his own; for he says, “Walk in the light of your own fire, and in the flame which you have kindled.” By these words it seems to be indicated that every sinner kindles for himself the flame of his own fire, and is not plunged into some fire which has been already kindled by another, or was in existence before himself. Of this fire the fuel and food are our sins, which are called by the Apostle Paul “wood, and hay, and stubble.” And I think that, as abundance of food, and provisions of a contrary kind and amount, breed fevers in the body, and fevers, too, of different sorts and duration, according to the proportion in which the collected poison supplies material and fuel for disease (the quality of this material, gathered together from different poisons, proving the causes either of a more acute or more lingering disease); so, when the soul has gathered together a multitude of evil works, and an abundance of sins against itself, at a suitable time all that assembly of evils boils up to punishment, and is set on fire to chastisements; when the mind itself, or conscience, receiving by divine power into the memory all those things of which it had stamped on itself certain signs and forms at the moment of sinning, will see a kind of history, as it were, of all the foul, and shameful, and unholy deeds which it has done, exposed before its eyes: then is the conscience itself harassed, and, pierced by its own goads, becomes an accuser and a witness against itself. And this, I think, was the opinion of the Apostle Paul himself, when he said, “Their thoughts mutually accusing or excusing them in the day when God will judge the secrets of men by Jesus Christ, according to my Gospel.” From which it is understood that around the substance of the soul certain tortures are produced by the hurtful affections of sins themselves.
5. And that the understanding of this matter may not appear very difficult, we may draw some considerations from the evil effects of those passions which are wont to befall some souls, as when a soul is consumed by the fire of love, or wasted away by zeal or envy, or when the passion of anger is kindled, or one is consumed by the greatness of his madness or his sorrow; on which occasions some, finding the excess of these evils unbearable, have deemed it more tolerable to submit to death than to endure perpetually torture of such a kind. You will ask indeed whether, in the case of those who have been entangled in the evils arising from those vices above enumerated, and who, while existing in this life, have been unable to procure any amelioration for themselves, and have in this condition departed from the world, it be sufficient in the way of punishment that they be tortured by the remaining in them of these hurtful affections, i.e., of the anger, or of the fury, or of the madness, or of the sorrow, whose fatal poison was in this life lessened by no healing medicine; or whether, these affections being changed, they will be subjected to the pains of a general punishment. Now I am of opinion that another species of punishment may be understood to exist; because, as we feel that when the limbs of the body are loosened and torn away from their mutual supports, there is produced pain of a most excruciating kind, so, when the soul shall be found to be beyond the order, and connection, and harmony in which it was created by God for the purposes of good and useful action and observation, and not to harmonize with itself in the connection of its rational movements, it must be deemed to bear the chastisement and torture of its own dissension, and to feel the punishments of its own disordered condition. And when this dissolution and rending asunder of soul shall have been tested by the application of fire, a solidification undoubtedly into a firmer structure will take place, and a restoration be effected.
