Reply to Objection 3: The purpose of this cleansing will be chiefly to remove all imperfection from the abode of the saints; and consequently in this cleansing all that is foul will be brought together to the place of the damned: so hell will not be cleansed, and the dregs of the whole earth will be brought thither, according to Ps. 74:9, "The dregs thereof are not emptied, all the sinners of the earth shall drink."
Reply to Objection 4: Although the sin of the first man was committed in the earthly paradise, this is not the place of sinners, as neither is the empyrean heaven: since from both places man and devil were expelled forthwith after their sin. Consequently that place needs no cleansing.
Whether the fire of the final conflagration is to follow the judgment?
Objection 1: It would seem that the fire of the final conflagration is to follow the judgment. For Augustine (De Civ. Dei xx, 30) gives the following order of the things to take place at the judgment, saying: "At this judgment we have learned that the following things will occur. Elias the Thesbite will appear, the Jews will believe, Antichrist will persecute, Christ will judge, the dead shall rise again, the good shall be separated from the wicked, the world shall be set on fire and shall be renewed." Therefore the burning will follow the judgment.
Objection 2: Further, Augustine says (De Civ. Dei xx, 16): "After the wicked have been judged, and cast into everlasting fire, the figure of this world will perish in the furnace of worldly flames." Therefore the same conclusion follows.
Objection 3: Further, when the Lord comes to judgment He will find some men living, as appears from the words of 1 Thess. 4:16, where the Apostle speaking in their person says: "Then we who are alive, who remain unto the coming of the Lord [*Vulg.: 'who are left, shall be taken . . . to meet Christ'---the words "who remain," etc., are from 1 Thess. 4:14 ]." But it would not be so, if the burning of the world were to come first, since they would be destroyed by the fire. Therefore this fire will follow the judgment.
Objection 4: Further, it is said that our Lord will come to judge the earth by fire, and consequently the final conflagration would seem to be the execution of the sentence of Divine judgment. Now execution follows judgment. Therefore that fire will follow the judgment.
On the contrary, It is written ( Ps. 96:3 ): "A fire shall go before Him."
Further, the resurrection will precede the judgment, else every eye would not see Christ judging. Now the burning of the world will precede the resurrection, for the saints who will rise again will have spiritual and impassible bodies, so that it will be impossible for the fire to cleanse them, and yet the text (Sent. iv, D, 47) quotes Augustine (De Civ. Dei xx, 18) as saying that "whatever needs cleansing in any way shall be cleansed by that fire." Therefore that fire will precede the judgment.
I answer that, The fire in question will in reality, as regards its beginning, precede the judgment. This can clearly be gathered from the fact that the resurrection of the dead will precede the judgment, since according to 1 Thess. 4:13-16 , those who have slept "shall be taken up . . . in the clouds . . . into the air . . . to meet Christ coming to judgment." Now the general resurrection and the glorification of the bodies of the saints will happen at the same time; for the saints in rising again will assume a glorified body, as evidenced by 1 Cor. 15:43, "It is sown in dishonor, it shall rise in glory": and at the same time as the saints' bodies shall be glorified, all creatures shall be renewed, each in its own way, as appears from the statement ( Rom. 8:21 ) that "the creature . . . itself shall be delivered from the servitude of corruption into the liberty of the glory of the children of God." Since then the burning of the world is a disposition to the aforesaid renewal, as stated above (AA[1],4); it can clearly be gathered that this burning, so far as it shall cleanse the world, will precede the judgment, but as regards a certain action thereof, whereby it will engulf the wicked, it will follow the judgment.
Reply to Objection 1: Augustine is speaking not as one who decides the point, but as expressing an opinion. This is clear from his continuing thus: "That all these things are to happen is a matter of faith, but how and in what order we shall learn more then by experience of the things themselves than now by seeking a definite conclusion by arguing about them. Methinks, however, they will occur in the order I have given." Hence it is clear that he is speaking as offering his opinion. The same answer applies to the Second Objection.
Reply to Objection 3: All men shall die and rise again: yet those are said to be found alive who will live in the body until the time of the conflagration.
Reply to Objection 4: That fire will not carry out the sentence of the judge except as regards the engulfing of the wicked: in this respect it will follow the judgment.
Whether that fire will have such an effect on men as is described?
Objection 1: It would seem that this fire will not have such an effect on men as is described in the text (Sent. iv, D, 47). For a thing is said to be consumed when it is reduced to naught. Now the bodies of the wicked will not be reduced to naught, but will be kept for eternity, that they may bear an eternal punishment. Therefore this fire will not consume the wicked, as stated in the text.
Objection 2: Further, if it be said that it will consume the bodies of the wicked by reducing them to ashes; on the contrary, as the bodies of the wicked, so will those of the good be brought to ashes: for it is the privilege of Christ alone that His flesh see not corruption. Therefore it will consume also the good who will then be found.
Objection 3: Further, the stain of sin is more abundant in the elements, as combining together to the formation of the human body wherein is the corruption of the fomes [*Cf. FS, Q[83], A[3]; FS, Q[91], A[6]] even in the good, than in the elements existing outside the human body. Now the elements existing outside the human body will be cleansed on account of the stain of sin. Much therefore will the elements in the human body whether of the good or of the wicked need to be cleansed, and consequently the bodies of both will need to be destroyed.
Objection 4: Further, as long as the state of the way lasts the elements act in like manner on the good and the wicked. Now the state of the way will still endure in that conflagration, since after this state of the way death will not be natural, and yet it will be caused by that fire. Therefore that fire will act equally on good and wicked; and consequently it does not seem that any distinction is made between them as to their being affected by that fire, as stated in the text.
Objection 5: Further, this fire will have done its work in a moment as it were. Yet there will be many among the living in whom there will be many things to be cleansed. Therefore that fire will not suffice for their cleansing.
I answer that, This fire of the final conflagration, in so far as it will precede the judgment, will act as the instrument of Divine justice as well as by the natural virtue of fire. Accordingly, as regards its natural virtue, it will act in like manner on the wicked and good who will be alive, by reducing the bodies of both to ashes. But in so far as it acts as the instrument of Divine justice, it will act differently on different people as regards the sense of pain. For the wicked will be tortured by the action of the fire; whereas the good in whom there will be nothing to cleanse will feel no pain at all from the fire, as neither did the children in the fiery furnace ( Dan. 3 ); although their bodies will not be kept whole, as were the bodies of the children: and it will be possible by God's power for their bodies to be destroyed without their suffering pain. But the good, in whom matter for cleansing will be found, will suffer pain from that fire, more or less according to their different merits.
On the other hand, as regards the action which this fire will have after the judgment, it will act on the damned alone, since the good will all have impassible bodies.
Reply to Objection 1: Consumption there signifies being brought, not to nothing, but to ashes.
Reply to Objection 2: Although the bodies of the good will be reduced to ashes by the fire, they will not suffer pain thereby, as neither did the children in the Babylonian furnace. In this respect a distinction is drawn between the good and the wicked.
Reply to Objection 3: The elements that are in human bodies, even in the bodies of the elect, will be cleansed by fire. But this will be done, by God's power, without their suffering pain.
Reply to Objection 4: This fire will act not only according to the natural power of the element, but also as the instrument of Divine justice.
