In the first century A.D., still confining ourselves to specifically Jewish Apocalyptic literature we find various changes taking place. The eternal Messianic kingdom passes largely out. The temporary Messianic kingdom becomes an eternal national one. The interest of the individual Jew comes to center on his own lot in the future life.[4] We have to pass a number of writers; Assumption of Moses, Philo, etc., before we come to the specific statement of Chiliasm proper, i.e., the duration of the Messianic kingdom for 1000 years. In the Book of The Secrets of Enoch commonly known as II Enoch (1-50 A.D.) we find for the first time the doctrine which was taken over to make the Christian Millennium. The writer of II Enoch was an Egyptian Jew. He says that as the world was made in six days, its course will run for six thousand years. The 6000 years will be followed by a Messianic kingdom of rest and blessedness lasting 1000 years. After that follows the final judgment, "The great day of the Lord." Passing now to the New Testament, it is only necessary for our purpose to enumerate three different concepts of the Messianic kingdom that are found therein. In these concepts contemporaneous Jewish ideas are taken with more or less transformation. The first conception perhaps holds the idea of a present world kingdom but puts emphasis on the futurity of the kingdom. Its ultimate consumation is not by gradual, natural development, but by the catastrophic reappearance of Christ. This Second Advent is to be preceded by tremendous portents of the most terrible sort. The second conception is that the kingdom is already present in Christ's appearance as the Messiah. It is to grow by the natural laws of spiritual development to its full realization. A considerable length of time is conceived as necessary for the attainment of mature growth. The consumation of the kingdom in the Second Advent is to be unexpected and sudden and none but the Father knows when it will take place. The third conception, that of Chiliasm, is that the Second Advent of Christ is close at hand. Anti Christ and his confederates are to be destroyed at Megiddo. Satan is to be bound for 1000 years during which is the Millennium, when the martyrs are raised in the first resurrection and reign with Christ at Jerusalem. This conception is found in the Revelation and perhaps I Cor. XV, 24-27. All the essential elements of it are to be found in pre-existing sources, e.g., the 1000 years in II Enoch, the reign of the saints in Testaments of the XII Patriarchs, etc.
