Well, it's just a question, really.
I do think that Justin Martyr, Irenaeus and other Classical-era Christians really did, as they seemingly wrote, believe in a sexta-/septa-millennial interpretation of
Revelations.
Nero = Caesars = 666 = anti-Christian pagan imperial Lords of the 6th Biblical Day (to 500 AD)
Which 6th Biblical Day would end in the expected
Christian Millennium of the
7th Biblical Day (to 1500 AD).
That would make the present era the
8th Biblical Day... and Christians have been equating Jesus with
888 for two thousand years... I don't claim to know what it might mean or otherwise.. Just seems significant, being based on Scripture, and ancient Church Traditions.
Note that Hebrew "24 hour days" begin at dusk. Such that the latter half of the 6th Biblical Day (birth of Christ to 500 AD) would have figuratively been the "dawn to dusk" "daytime daylight hours" thereof. Likewise, if the 8th Biblical Day began in the 15th century AD, then 2000 AD --
cp. "Y2K" and "Maya 2012" -- was the "dawn" of the "daylight hours" thereof. That seems possibly significant, because many people apparently perceived powerful spiritual forces at work around the turn of the millennium. So the fact that it would have actually been coincident exactly with the "daybreak of dawn" on the 8th Biblical Day could possibly be actually Spiritually significant.
To truly understand what these early Christians believed, we need to examine the time at which they expected these things to take place. Barnabas said:
“The Sabbath is mentioned at the beginning of the creation [thus]: ‘And God made in six days the works of His hands, and made an end on the seventh day, and rested on it, and sanctified it.’Attend, my children, to the meaning of this expression, ‘He finished in six days.’ This implieth that the Lord will finish all things in six thousand years, for a day is with Him a thousand years. And He Himself testifieth, will be as a thousand years. Therefore, my children, in six days, that is, in six thousand years, all things will be finished. ‘And He rested on the seventh day.’ This meaneth: when His Son, coming [again], shall destroy the time of the wicked man, and judge the ungodly, and change the-sun, and the moon, and the stars, then shall He truly rest on the seventh day. Moreover, He says, ‘Thou shalt sanctify it with pure hands and a pure heart.’ If, therefore, any one can now sanctify the day which God hath sanctified, except he is pure in heart in all things, Behold, therefore: certainly then one properly resting sanctifies it, when we ourselves, having received the promise, wickedness no longer existing, and all things having been made new by the Lord, shall be able to work righteousness. Then we shall be able to sanctify it, having been first sanctified ourselves.” (Epistle of Barnabas, chapter XV)
In commenting on “the beast,” Irenaeus said,
“‘And he will cause a mark [to be put] in the forehead and in the right hand, that no one may be able to buy or sell, unless he who has the mark of the name of the beast or the number of his name; and the number is six hundred and sixty-six,’ that is, six times a hundred, six times ten, and six units. [He gives this] as a summing up of the whole of that apostasy which has taken place during six thousand years.
“For in as many days as this world was made, in so many thousand years shall it be concluded. And for this reason the Scripture says: ‘Thus the heaven and the earth were finished, and all their adornment. And God brought to a conclusion upon the sixth day the works that He had made; and God rested upon the seventh day from all His works.’This is an account of the things formerly created, as also it is a prophecy of what is to come. For the day of the Lord is as a thousand years; and in six days created things were completed: it is evident, therefore, that they will come to an end at the sixth thousand year.” (Against Heresies, by Irenaeus, book V, chapter XXVII, sections 2-3)
Irenaeus further said,
“And again He says, “Whosoever shall have left lands, or houses, or parents, or brethren, or children because of Me, he shall receive in this world an hundred-fold, and in that to come he shall inherit eternal life.” For what are the hundred-fold [rewards] in this word, the entertainments given to the poor, and the suppers for which a return is made? 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, by Irenaeus, book V, chapter XXXIII, section 2)
Both Barnabas and Irenaeus clearly taught that the time when God destroys the Antichrist will be at the end of the earth’s six thousandth year. Now if either of these writers was using the chronology of the Hebrew text of the Old Testament, they would have thought that all this would take place nearly two thousand years into their future. But at this time almost all Christians used the Septuagint translation of the Hebrew scriptures into Greek. This translation added significant numbers of years to many of the time periods given in the Old Testament, making the age of our present creation at the time of the birth of Jesus about five and a half thousand years, instead of the familiar four thousand years given in the Hebrew text. So they most likely thought that all this would take place only hundreds of years into their future, rather than thousands of years. But regardless of whether they thought these things would take place hundreds or thousands of years later, they placed them far into their own futures.
Although neither Barnabas nor Irenaeus explicitly said that this kingdom would last a thousand years, they both put it far into the future and both strongly implied it by saying that the six days of creation represented six thousand years, and that the seventh day of rest represented the time of the kingdom.
Justin said nothing about the six thousand years, but clearly stated that the kingdom would be in the future and would last a thousand years, saying,
“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.
“For Isaiah spake thus concerning this space of a thousand years: ‘For there shall be the new heaven and the new earth, and the former shall not be remembered, or come into their heart; but they shall find joy and gladness in it, which things I create. For, Behold, I make Jerusalem a rejoicing, and My people a joy; and I shall rejoice over Jerusalem, and be glad over My people. And the voice of weeping shall be no more heard in her, or the voice of crying. And there shall be no more there a person of immature years, or an old man who shall not fulfil his days. For the young man shall be an hundred years old; but the sinner who dies an hundred years old, he shall be accursed. And they shall build houses, and shall themselves inhabit them; and they shall plant vines, and shall themselves eat the produce of them, and drink the wine. They shall not build, and others inhabit; they shall not plant, and others eat. For according to the days of the tree of life shall be the days of my people; the works of their toil shall abound... Now we have understood that the expression used among these words, ‘According to the days of the tree shall be the days of my people; the works of their toil shall abound’ obscurely predicts a thousand years. We have perceived, moreover, that the expression, ‘The day of the Lord is as a thousand years, is connected with this subject. 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.” (Dialogue With Trypho, by Justin Martyr, chapters LXXX-LXXXI)
Eusebius reported that Papias also said the kingdom would be in the future and would last a thousand years, saying, “The same writer gives also other accounts which he says came to him through unwritten tradition, certain strange parables and teachings of the Saviour, and some other more mythical things. To these belong his statement that there will be a period of some thousand years after the resurrection of the dead, and that the kingdom of Christ will be set up in material form on this very earth.” (The Church History, by Eusebius, book III, chapter XXXIX, sections 12-13.)
Irenaeus further commented on the future character of this kingdom, saying,
“Then again, speaking of Jerusalem, and of Him reigning there, Isaiah declares, ‘Thus saith the Lord, Happy is he who hath seed in Zion, and servants in Jerusalem. Behold, a righteous king shall reign, and princes shall rule with judgment.’ And with regard to the foundation on which it shall be rebuilt, he says: ‘Behold, I will lay in order for thee a carbuncle stone, and sapphire for thy foundations; and I will lay thy ramparts with jasper, and thy gates with crystal, and thy wall with choice stones: and all thy children shall be taught of God, and great shall be the peace of thy children; and in righteousness shalt thou be built up.’ And yet again does he say the same thing: ‘Behold, I make Jerusalem a rejoicing, and my people [a joy]; for the voice of weeping shall be no more heard in her, nor the voice of crying. Also there shall not be there any immature [one], nor an old man who does not fulfil his time: for the youth shall be of a hundred years; and the sinner shall die a hundred years old, yet shall be accursed. And they shall build houses, and inhabit them themselves; and shall plant vineyards, and eat the fruit of them themselves, and shall drink wine. And they shall not build, and others inhabit; neither shall they prepare the vineyard, and others eat. For as the days of the tree of life shall be the days of the people in thee; for the works of their hands shall endure.’” (Against Heresies, by Irenaeus, book V, chapter XXIV, section 4)
“Now all these things being such as they are, cannot be understood in reference to super-celestial matters; ‘for God, it is said,’ ‘will show to the whole earth that is under heaven thy glory.’ But in the times of the kingdom, the earth has been called again by Christ [to its pristine condition], and Jerusalem rebuilt after the pattern of the Jerusalem above, of which the prophet Isaiah says, ‘Behold, I have depicted thy walls upon my hands, and thou art always in my sight.’” (Against Heresies, by Irenaeus, book V, chapter XXXV, section 2)
We have now seen that the millennium was described as a future kingdom by Papias, Barnabas, Justin, and Irenaeus. This is all the Christian commentators on prophecy that wrote before the third century and whose works were preserved. We have also seen that both Papias and Justin explicitly said that this period would last a thousand years, and that both of the other two strongly implied it.
