As I said before, the focus of the Early Church Fathers was not about speculating on the character of the Millennium, nor on the fate of the wicked. Our hope was to be placed squarely on the destiny of the righteous, which is a reward for our faithfulness at the present time.
Focusing on the destiny of the righteous is not a valid argument against the state of the world during the Millennium. That would be an argument from silence.
Perhaps the Chiliasts simply didn't know how to describe it, or felt they didn't have enough information to discuss it? At any rate, too much speculation could draw readers away from the more important points that would direct men to live in righteousness and to pursue a new earth as a reward for obedience.
Irenaeus:
It is necessary to tell them respecting those things, that it behoves the righteous first to receive the promise of the inheritance which God promised to the fathers, and to reign in it, when they rise again to behold God in this creation which is renovated, and that the judgment should take place afterwards. For it is just that in that very creation in which they toiled or were afflicted, being proved in every way by suffering, they should receive the reward of their suffering; and that in the creation in which they were slain because of their love to God, in that they should be revived again; and that in the creation in which they endured servitude, in that they should reign. For God is rich in all things, and all things are His. It is fitting, therefore, that the creation itself, being restored to its primeval condition, should without restraint be under the dominion of the righteous; and the apostle has made this plain in the Epistle to the Romans, when he thus speaks: “For the expectation of the creature waiteth for the manifestation of the sons of God. For the creature has been subjected to vanity, not willingly, but by reason of him who hath subjected the same in hope; since the creature itself shall also be delivered from the bondage of corruption into the glorious liberty of the sons of God” (Against Heresies Book V, Chapter 32:1).
Irenaeus testifies to the curse being lifted in a future millennium. The earth, in his opinion, will be returned to its pre-fall state. This coincides with the glorification of the just. For him: “the pain of the stroke” … the Lord will heal when He raises us from the dead, and restores the inheritance of the fathers.” He contends: “the [earthly] kingdom … is the commencement of incorruption.” Speaking of the “the resurrection of the just” he submits: “they rise again to behold God in this creation which is renovated.” The earth, the writer anticipates, is only for the righteous. He affirms: “It is fitting, therefore, that the creation itself, being restored to its primeval condition, should without restraint be under the dominion of the righteous.” There is no allowance, as modern-day Premillennialism argues, for the curse, the wicked wickedness, or Satan to blight the new earth. This thousand-year era is depicted as the Sabbath reign of Christ and the righteous.
Irenaeus also advocated that it is fitting that the resurrected saints would reign in the same world where they had labored and suffered bodily. Where they once endured pain and bondage, they would enjoy freedom and authority. Man and creation are portrayed as being in perfect sync. The one notable aspect of early Chiliasm, which distinguishes it from modern Premillennialism, is its view of a future millennial earth. The early Chiliasts expected a perfect regenerated earth free of sin, sinners, Satan and the curse. Modern-day Premillennialism locates all of this on its future millennial earth.
This would be a it was only just that they be raised bodily and given rewards in the same world in which they had suffered. , on this A theme first expressed most explicitly and most forcefully by Irenaeus was that since the saints
Irenaeus states:
The Lord will come from heaven in the clouds, in the glory of the Father, sending this man (Antichrist ) and those who follow him into the lake of fire; but bringing in for the righteous the times of the kingdom, that is, the rest, the hallowed seventh day; and restoring to Abraham the promised inheritance, in which kingdom the Lord declared, that “many coming from the east and from the west should sit down with Abraham, Isaac, and Jacob” (Against Heresies Book V, Chapter 32:1).
The picture being portrayed here is that of a perfect environment consisting perfected beings being at total rest. This is a picture of millennial bliss.
Irenaeus adds:
These are [to take place] in the times of the kingdom, that is, upon the seventh day, which has been sanctified, in which God rested from all the works which He created, which is the true Sabbath of the righteous, which they shall not be engaged in any earthly occupation; but shall have a table at hand prepared for them by God, supplying them with all sorts of dishes. (Against Heresies Book V, Chapter 33:2).
The millennial earth is depicted as heaven on earth. It is devoid of any form of corruption or rebellion. There is no allowance made for the wicked. It is the abode of the righteous alone who are depicted as enjoying the bliss and rest of paradise before the fall.
Irenaeus elaborates on the early Chiliast expectation in a future millennium:
For as it is God truly who raises up man, so also does man truly rise from the dead, and not allegorically … and shall go forwards and flourish in the times of the kingdom, in order that he may be capable of receiving the glory of the Father (Against Heresies Book V, Chapter 35:2).
Tertullian:
Previous to Christ’s coming, our prayers are directed towards the end of this world, to the passing away thereof at the great day of the Lord— of His wrath and vengeance— the last day, which is hidden (from all), and known to none but the Father, although announced beforehand by signs and wonders, and the dissolution of the elements, and the conflicts of nations (On the Resurrection of the Flesh, Chapter XXII).
What a spectacle is that fast-approaching advent of our Lord, now owned by all, now highly exalted, now a triumphant One! What that exultation of the angelic hosts! What the glory of the rising saints! What the kingdom of the just thereafter! What the city New Jerusalem! Yes, and there are other sights: that last day of judgment, with its everlasting issues; that day unlooked for by the nations, the theme of their derision, when the world hoary with age, and all its many products, shall be consumed in one great flame! (De Spectaculis, Chapter XXX).
Tertullian locates the second coming at “the last day” – which is “the end of this world, to the passing away thereof at the great day of the Lord the day.” This is the day of Christ’s “wrath and vengeance.” It is an approaching day that “is hidden (from all), and known to none but the Father, although announced beforehand by signs and wonders, and the dissolution of the elements, and the conflicts of nations.”
Where exactly are the saints said to be during the Chiliast millennium? Tertullian locates them in the New Jerusalem in Against Marcion Book III, Chapter XXV. This is believed to descend upon the millennial earth:
We do confess that a kingdom is promised to us upon the earth, although before heaven, only in another state of existence; inasmuch as it will be after the resurrection for a thousand years in the divinely-built city of Jerusalem, let down from heaven … We say that this city has been provided by God for receiving the saints on their resurrection, and refreshing them with the abundance of all really spiritual blessings, as a recompense for those which in the world we have either despised or lost; since it is both just and God-worthy that His servants should have their joy in the place where they have also suffered affliction for His name’s sake.
Tertullian tells us that “the saints on their resurrection” will possess “the divinely-built city of Jerusalem” which is said to be “let down from heaven” unto “the earth” at Christ’s Coming, “only in another state of existence.” The writer then suggests that the redeemed that are alive when Jesus comes experience “a sudden change, to become qualified to join the rising saints.” Tertullian describes our current corrupt bodies as “the garment of the flesh” which must (of necessity) be “put off” at the Second Coming.
Like Irenaeus, Tertullian seems to see the return of man to this current earth in its perfected form in his new glorified body as a sign of ultimate victory over sin. The redeemed are therefore suitably rewarded for their sufferings in this life. Where they suffered loss, they now experience gain. Where they suffered “affliction” they now experience “joy.” This anticipated millennial earth is represented as a vindication of the saints.
Hippolytus briefly states:
The righteous shall obtain the incorruptible and unfading kingdom, who indeed are at present detained in Hades (Fragments of Hippolytus 1).
He does not seem to go into detail on the matter of discipline in a future millennial kingdom. Like his view on Hades for the dead in Christ, he seems to anticipate a state and an age that is full of rewards for the righteous and full of rest.
