Lactantius — Divine Institutes 7.24

Now I will subjoin the rest. Therefore the Son of the most high and mighty God shall come to judge the quick and the dead, as the Sibyl testifies and says:— For then there shall be confusion of mortals throughout the whole earth, when the Almighty Himself shall come on His judgment-seat to judge the souls of the quick and dead, and all the world. But He, when He shall have destroyed unrighteousness, and executed His great judgment, and shall have recalled to life the righteous, who have lived from the beginning, will be engaged among men a thousand years , and will rule them with most just command. Which the Sibyl proclaims in another place, as she utters her inspired predictions:— Hear me, you mortals; an everlasting King reigns.

Then they who shall be alive in their bodies shall not die, but during those thousand years shall produce an infinite multitude, and their offspring shall be holy , and beloved by God ; but they who shall be raised from the dead shall preside over the living as judges. But the nations shall not be entirely extinguished, but some shall be left as a victory for God , that they may be the occasion of triumph to the righteous, and may be subjected to perpetual slavery. About the same time also the prince of the devils, who is the contriver of all evils , shall be bound with chains, and shall be imprisoned during the thousand years of the heavenly rule in which righteousness shall reign in the world, so that he may contrive no evil against the people of God .

After His coming the righteous shall be collected from all the earth, and the judgment being completed, the sacred city shall be planted in the middle of the earth, in which God Himself the builder may dwell together with the righteous, bearing rule in it. And the Sibyl marks out this city when she says:— And the city which God made, this He made more brilliant than the stars, and sun, and moon.

Then that darkness will be taken away from the world with which the heaven will be overspread and darkened, and the moon will receive the brightness of the sun, nor will it be further diminished: but the sun will become seven times brighter than it now is; and the earth will open its fruitfulness, and bring forth most abundant fruits of its own accord; the rocky mountains shall drop with honey; streams of wine shall run down, and rivers flow with milk: in short, the world itself shall rejoice , and all nature exult, being rescued and set free from the dominion of evil and impiety, and guilt and error . Throughout this time beasts shall not be nourished by blood, nor birds by prey; but all things shall be peaceful and tranquil.
