Revelation 20:4 Douay-Rheims

And I saw seats; and they sat upon them; and judgment was given unto them; and the souls of them that were beheaded for the testimony of Jesus, and for the word of God, and who had not adored the beast nor his image, nor received his character on their foreheads, or in their hands; and they lived and reigned with Christ a thousand years.

“And further, there was a certain man with us, whose name was John, one of the apostles of Christ, who prophesied, by a revelation that was made to him, that those who believed in our Christ would dwell a thousand years in Jerusalem; and that thereafter the general, and, in short, the eternal resurrection and judgment of all men would likewise take place.”

“But I and others, who are right-minded Christians on all points, are assured that there will be a resurrection of the dead, and a thousand years in Jerusalem, which will then be built, adorned, and enlarged, [as] the prophets Ezekiel and Isaiah and others declare.”

“What hope and reward remains for the righteous and for martyrs after the conflicts and sufferings of this present time, The Holy Spirit shows and predicts by Solomon, saying: "And although in the sight of men they suffered torments, yet their hope is full of immortality. And having been troubled in a few things, they shall be in many happily ordered, because God has tried them, and has found them worthy of Himself. As gold in the furnace, He hath tried them; and as whole burnt-offerings of sacrifice, He hath received them, and in its season there will be respect of them. They will shine and run about as sparks in a place set with reeds. They shall judge the nations, and have dominion over the peoples; and their Lord shall reign for ever." In the same also our vengeance is described, and the repentance of those who persecute and molest us is announced. "Then," saith he," shall the righteous stand in great constancy before such as have afflicted them, and who have taken away their labours; when they see it, they shall be troubled with a horrible fear: and they shall marvel at the suddenness of their unexpected salvation, saying among themselves, repenting and groaning for anguish of spirit, These are they whom we had sometime in derision and as a proverb of reproach. We fools counted their life madness, and their end to be without honour. How are they numbered among the children of God, and their lot is among the saints! Therefore have we erred from the way of truth, and the light of righteousness hath not shined unto us, and the sun hath not risen upon us. We have been wearied in the way of unrighteousness and perdition, and have walked through hard deserts, but have not known the way of the Lord. What hath pride profited us, or what hath the boasting of riches brought to us? All these things have passed away like a shadow." Likewise in the cxvth Psalm is shown the price and the reward of suffering: "Precious," it says, "in the sight of the Lord is the death of His saints. In the cxxvth Psalm also is expressed the sadness of the struggle, and the joy of the retribution: "They who sow," it says. "in tears, shall reap in joy. As they walked, they walked and wept, casting their seeds; but as they come again, they shall come in exultation, bearing their sheaves." And again, in the cxviiith Psalm: "Blessed are those that are undefiled in the way, who walk in the law of the Lord. Blessed are they who search His testimonies, and seek Him out with their whole heart." Moreover, the Lord in the Gospel, Himself the avenger of our persecution and the rewarder of our suffering, says: "Blessed are they who suffer persecution for righteousness' sake, for theirs is the kingdom of heaven." And again: "Blessed shall ye be when men shall hate you, and shall separate you, and shall expel you, and shall revile your name as evil, for the Son of man's sake. Rejoice ye in that day, and leap for joy; for, behold, your reward is great in heaven." And once more: "Whosoever shall lose his life for my sake, the same shall save it." Nor do the rewards of the divine promise attend those alone who are reproached and slain; but if the passion itself, be wanting to the faithful, while their faith has remained sound and unconquered, and having forsaken and contemned all his possessions, the Christian has shown that he is following Christ, even be also is honoured by Christ among the martyrs, as He Himself promises and says: "There is no man that leaveth house, or land, or parents, or brethren, or wife, or children, for the kingdom of God's sake, but shall receive seven times as much in this present time, and in the world to come eternal life." In the Apocalypse also He says the same thing: "And I saw," saith he, "the souls of them that were slain for the name of Jesus and the word of God." And when he had placed those who were slain in the first place, he added, saying: "And whosoever had not worshipped the image of the beast, neither had received his mark upon their forehead or in their hand; "all these he joins together, as seen by him at one time in the same place, and says, "And they lived and reigned with Christ." He says that all live and reign with Christ, not only who have been slain; but even whosoever, standing in firmness of the faith and in the fear of God, have not worshipped the image of the beast, and have not consented to his deadly and sacrilegious edicts.”

“"And I saw thrones, and them that sate upon them, and judgment was given unto them; and I saw the souls of them that were slain on account of the testimony of Jesus, and for the word of God, and which had not worshipped the beast nor his image, nor have received his writing on their forehead or in their hand; and they reigned with Christ for a thousand years: the rest of them lived not again until the thousand years were finished. This is the first resurrection." There are two resurrections. But the first resurrection is now of the souls that are by the faith, which does not permit men to pass over to the second death. Of this resurrection the apostle says: "If ye have risen with Christ, seek those things which are above."”

“Therefore they are not to be heard who assure themselves that there is to be an earthly reign of a thousand years; who think, that is to say, with the heretic Cerinthus. For the kingdom of Christ is now eternal in the saints, although the glory of the saints shall be manifested after the resurrection.”

Augustine of Hippo Patristic
A.D. 354–430
“During the "thousand years" when the devil is bound, the saints also reign for a "thousand years" and, doubtless, the two periods are identical and mean the span between Christ's first and second coming. For not only in that future kingdom to which Christ referred in the words, "Come, blessed of my Father, take possession of the kingdom prepared for you," but even now those saints reign with him in some authentic though vastly inferior fashion. To them he said, "Behold, I am with you all days, even to the consummation of the world." … This, to be sure, is the period in which the scribe instructed in the kingdom of heaven brings forth from his storeroom things new and old, as I mentioned above. So, too, the reapers are to gather up out of the church the weeds, which he allows to grow intermixed with the wheat up to the time of harvest.… This certainly cannot be the kingdom that is to be utterly without scandals. The kingdom from which scandals are gathered out, then, must be the church on earth.… The mixed kingdom must be the church, such as she exists in her temporal stage, while the unmixed kingdom is the church such as she will be when she is to contain no evildoer. Consequently the church, even in this world, here and now, is the kingdom of Christ and the kingdom of heaven. Here and now Christ's saints reign with him, although not in the way they are destined to reign hereafter; but the "weeds" do not reign with him, even now, though they grow along with the "wheat" in the church.… Those alone reign with Christ whose presence in his kingdom is such that they themselves are his kingdom.… Now it is of this militant stage of the kingdom, during which there is still war with our enemy, alternating victory over, and defeat before, our evil inclinations, that the Apocalypse speaks. The "thousand years" are to last until we come to that kingdom, free of the foe, where the saints reign in fullest peace.… After mentioning the devil's chaining for a thousand years and his brief interval of freedom to follow, John sums up the activity of and in the church during the "thousand years": "And I saw thrones, and men sat upon them and judgment was given to them." Now there is no question of the last judgment in this verse. The thrones and the enthroned people are the prelates who govern the church here and now. And the judgment is best interpreted as the one contained in the words, "Whatever you bind on earth shall be bound also in heaven, and whatever you loose on earth shall be loosed also in heaven." We are to understand as implied by the words that come further on that these souls of the martyrs "reigned with Christ a thousand years"—of course, not yet reunited with their bodies. For the souls of the faithful departed are not divorced from Christ's kingdom, which is the temporal church. If they were, we should not be mindful of them at God's altar in the communion of the body of Christ; nor would there be any point in hastening one's baptism in time of danger, lest one die unbaptized; nor in seeking reconciliation, when one has been cut off from Christ's body by a sinful conscience or by the church's penitential discipline. Why do we go to all this trouble if the faithful departed are not still Christ's members? We may be sure, then, that their souls reign with him, just as their bodies will in time to come, even while the thousand years are rolling on.… We conclude, therefore, that even now, in time, the church reigns with Christ both in its living and departed members. "For to this end Christ died," says Paul, "and rose again, that he might be Lord both of the dead and of the living." If John mentions only the souls of the martyrs, that is because they who have battled for the truth unto death reign in death with a special splendor. But as the part is here used for the whole, we know that the words apply to the remaining faithful who belong to the same church, which is Christ's kingdom. This verse should be applied to both the living and the dead.… As to the identity of the beast in question, there is need of very careful study. Nevertheless, consistently with sound faith, one may take it to be the godless city as opposed to the city of God, men and women without faith as opposed to those who believe. The beast's "image," I think, is his deception as found, for example, in such people as profess the faith yet live like pagans. For they pretend to be what, in fact, they are not, and are called Christians, not because of full faith but of false face. The beast possesses, in addition to the openly avowed enemies of Christ's name and of his glorious city, the "weeds" that are marked for uprooting from his kingdom, the church, at the end of the world. Those who do not follow the beast or his image are surely those who follow Paul's admonition: "Do not bear the yoke with unbelievers." Their not worshiping means their not agreeing with, their not becoming subjects to, unbelievers. Their not accepting his "mark" upon their "foreheads" and "hands" means that they refuse the stigma of false faith and bad morals. Such people, alive or dead, keep themselves aloof from such evils and so reign with Christ, even now, in a fashion befitting the passage of time, throughout this whole era indicated by the "thousand years."”

“I saw thrones - Christianity established in the earth, the kings and governors being all Christians. Reigned with Christ a thousand years - I am satisfied that this period should not be taken literally. It may signify that there shall be a long and undisturbed state of Christianity; and so universally shall the Gospel spirit prevail, that it will appear as if Christ reigned upon earth; which will in effect be the case, because his Spirit shall rule in the hearts of men; and in this time the martyrs are represented as living again; their testimony being revived, and the truth for which they died, and which was confirmed by their blood, being now everywhere prevalent. As to the term thousand years, it is a mystic number among the Jews. Midrash Tillin, in Psa 90:15, Make us glad according to the days wherein thou hast afflicted us, adds, "by Babylon, Greece, and the Romans; and in the days of the Messiah. How many are the days of the Messiah? Rab. Elieser, the son of R. Jose, of Galilee, said, The days of the Messiah are a thousand years." Sanhedrin, fol. 92, 1, cited by the Aruch, under the word אירק says: "There is a tradition in the house of Elias, that the righteous, whom the holy blessed God shall raise from the dead, shall not return again to the dust; but for the space of a thousand years, in which the holy blessed God shall renew the world, they shall have wings like the wings of eagles, and shall fly above the waters." It appears therefore that this phraseology is purely rabbinical. Both the Greeks and Latins have the same form of speech in speaking on the state of the righteous and wicked after death. There is something like this in the Republic of Plato, book x., p. 322, edit. Bip., where, speaking of Erus, the son of Armenius, who came to life after having been dead twelve days, and who described the states of departed souls, asserting "that some were obliged to make a long peregrination under the earth before they arose to a state of happiness, ειναι δε την πορειαν χιλιετη, for it was a journey of a thousand years," he adds, "that, as the life of man is rated at a hundred years, those who have been wicked suffer in the other world a ten-fold punishment, and therefore their punishment lasts a thousand years." A similar doctrine prevailed among the Romans; whether they borrowed it from the Greeks, or from the rabbinical Jews, we cannot tell. Thus Virgil, speaking of the punishment of the wicked in the infernal regions, says: - Has omnes, ubi Mille rotam volvere per annos, Lethaeum ad fluvium Deus evocat agmine magno: Scilicet immemores supera ut convexa revisant, Rursus et incipiant in corpora velle reverti. Aen., lib. vi., 748. "But when a thousand rolling years are past, So long their dreary punishment shall last, Whole droves of spirits, by the driving god, Are led to drink the deep Lethean flood In large, forgetful draughts, to sleep the cares Of their past labors and their irksome years; That, unremembering of its former pain, The soul may clothe itself with flesh again." How the apostle applies this general tradition, or in what sense he may use it, who can tell?”

“they sat--the twelve apostles, and the saints in general. judgment was given unto there--(See on Dan 7:22). The office of judging was given to them. Though in one sense having to stand before the judgment-seat of Christ, yet in another sense they "do not come into judgment (Greek), but have already passed from death unto life." souls--This term is made a plea for denying the literality of the first resurrection, as if the resurrection were the spiritual one of the souls of believers in this life; the life and reign being that of the soul raised in this life from the death of sin by vivifying faith. But "souls" expresses their disembodied state (compare Rev 6:9) as John saw them at first; "and they lived" implies their coming to life in the body again, so as to be visible, as the phrase, Rev 20:5, "this is the first resurrection," proves; for as surely as "the rest of the dead lived not (again) until," &c., refers to the bodily general resurrection, so must the first resurrection refer to the body. This also accords with Co1 15:23, "They that are Christ's at His coming." Compare Psa 49:11-15. From Rev 6:9, I infer that "souls" is here used in the strict sense of spirits disembodied when first seen by John; though doubtless "souls" is often used in general for persons, and even for dead bodies. beheaded--literally, "smitten with an axe"; a Roman punishment, though crucifixion, casting to beasts, and burning, were the more common modes of execution. The guillotine in revolutionary France was a revival of the mode of capital punishment of pagan imperial Rome. Paul was beheaded, and no doubt shall share the first resurrection, in accordance with his prayer that he "might attain unto the resurrection from out of the rest of the dead" (Greek, "exanastasis"). The above facts may account for the specification of this particular kind of punishment. for . . . for--Greek, "for the sake of"; on account of"; "because of." and which--Greek, "and the which." And prominent among this class (the beheaded), such as did not worship the beast. So Rev 1:7, Greek, "and the which," or "and such as," particularizes prominently among the general class those that follow in the description [TREGELLES]. The extent of the first resurrection is not spoken of here. In Co1 15:23, Co1 15:51; Th1 4:14 we find that all "in Christ" shall share in it. John himself was not "beheaded," yet who doubts but that he shall share in the first resurrection? The martyrs are put first, because most like Jesus in their sufferings and death, therefore nearest Him in their life and reign; for Christ indirectly affirms there are relative degrees and places of honor in His kingdom, the highest being for those who drink his cup of suffering. Next shall be those who have not bowed to the world power, but have looked to the things unseen and eternal. neither--"not yet." foreheads . . . hands--Greek, "forehead . . . hand." reigned with Christ--over the earth.”

“And see thrones. The devil being bound, I saw the faithful loosed, and the lesser ones ready to obey their prelates, and the prelates to judge their subjects. I saw in the time of the binding the Church so loosed for working well, and at this same time I saw those who die for Christ enter at once into glory, never descending to the lower regions, as Abraham and the rest of the prophets descended, although they were just. And the souls of the beheaded. And I saw likewise the souls of those who did not adore. And they lived. And I do not say that they shall live and reign in the time to come, but also in this present time, namely, that from the time they were slain they lived and reigned with Christ.”
