The early Christians were taught to look for the return of Jesus Christ and it is evident, even from the New Testament, that some of them expected a speedy return. The literal interpretation of Revelation 20:1-6 led some of the early Church Fathers to distinguish between a first and a second resurrection and to believe in an intervening millennial kingdom. Some of them dwelt very fondly on these millennial hopes and pictured the enjoyments of the future age in a crassly materialistic manner. This is true, especially, of Papias and Irenaeus. Others, such as Barnabas, Hermas, Justin, and Tertullian, while teaching the doctrine, avoided its extravagances. The millennial doctrine also found favor with Cerinthus, the Ebionites, and the Montanists. But, it is not correct to say, as Premillenarians do, that it was generally accepted in the first three centuries. The truth of the matter is that the adherents of this doctrine were a rather limited number. There is no trace of it in Clement of Rome, Ignatius, Polycarp, Tatian, Athenagoras, Theophilus, Clement of Alexandria, Origen, Dionysius, and other important Church Fathers.
The Millenarianism of the early Church was gradually overcome. When centuries rolled by without the return of Jesus Christ, when persecutions ceased, and when Christianity received a sure footing in the Roman Empire and even became the State religion, the passionate longing for the appearance of Jesus Christ very naturally gave way for an adaptation of the Church to its present task. The allegorical interpretation of Scripture, introduced by the Alexandrian school and sponsored, especially, by Origen, also had a chilling effect on all millennial hopes. In the West, the powerful influence of Augustine was instrumental in turning the thoughts of the Church from the future to the present by his identification of the Church and the Kingdom of God. He taught the people to look for the millennium in the present Christian dispensation.
During the Middle Ages, Millenarianism was, generally, regarded as heretical. There were, it is true, here and there, transient and sporadic buddings of the millennial hope in the sects, but these exercised no profound influence. In the tenth century, there was a widespread expectation of the approaching end of the world, but this was not accompanied with chiliastic hopes, though it was associated with the idea of the speedy coming of the Antichrist. Christian art often chose its themes from eschatology. The hymn Dies Irae sounded the terrors of the coming judgment, painters depicted the end of the world on the canvas, and Dante gave a vivid description of hell in his Divina Comoedia.
At the time of the Reformation, the doctrine of the millennium was rejected by the Protestant Churches but revived in some of the sects, such as that of the more fanatical Anabaptists and that of the Fifth Monarchy Men. Luther scornfully rejected “the dream” that there would be an earthly kingdom of Christ preceding the day of judgment. The Augsburg Confession condemns those “who now scatter Jewish opinions that, before the resurrection of the dead, the godly shall occupy the kingdom of the world, the wicked being everywhere suppressed” (Art. XVII). And the Second Helvetic Confession says: “Moreover, we condemn the Jewish dreams that, before the day of judgment, there shall be a golden age in the earth and the godly shall possess the kingdoms of the world, their wicked enemies being trodden under foot” (Chapter XI).
A certain form of Millenarianism made its appearance, however, in the seventeenth century. There were several Lutheran and Reformed theologians who, while rejecting the idea of a visible reign of Christ on earth for a thousand years, advocated a more spiritual conception of the millennium. Their view of the matter was that, before the end of the world and the return of Jesus Christ, there will be a period in which the spiritual presence of Christ in the Church will be experienced in an unusual measure and a universal religious awakening will ensue. The Kingdom of Jesus Christ will, then, stand out as a kingdom of peace and righteousness. This was the early form of Post-, as distinguished from Premillennialism.
During the eighteenth and nineteenth centuries, the doctrine of the millennium again met with great favor in some circles. It was advocated by the school of Bengel and, more recently, by that of Erlangen, and numbered among its adherents such men as Hofmann, Delitzsch, Auberlen, Rothe, Elliott, Cumming, Bickersteth, the Bonars, Alford, Zahn, and others. There is a great diversity of opinion among these Premillenarians as to the order of the final events and the actual condition of things during the millennium. Repeated attempts have been made to fix the time of Christ’s return, which is, with great assurance, declared to be imminent but, up to the present, all these calculations have failed. Though there is a widepread belief today, especially in our country, that the return of Christ will be followed by a temporary visible reign of Christ on earth, yet the weight of theological opinion is against it. In liberal circles, a new form of Postmillennialism has made its appearance. The expected kingdom will consist of a new social order “in which the law of Christ shall prevail, and in which its prevalence shall result in peace, justice, and a glorious blossoming of present spiritual forces.” This is what [Walter] Rauschenbusch has in mind when he says, “We need a restoration of the millennial hope” (A Theology for the Social Gospel, p. 224). Up to the present time, however, the doctrine of the millennium has never yet been embodied in a single Confession and, therefore, cannot be regarded as a dogma of the Church.
