The Millenarian Heresy

From Unveiling the Apocalypse:

The Divine Will Movement rejects the amillenialism of St Augustine in favour of a "spiritual" version of the Chiliasm held by some early Christians, and holds that the "period of peace" promised by Our Lady of Fatima is actually an "era" that is equated with the Millennium of Rev 20. During this future "era of peace", they hold that Satan will be fully chained and all evil on earth will cease to exist. This is because the freedom of choice necessitated by human free will is going to be removed, and every person on earth will live according to the "Divine Will", during the establishment of the Kingdom of God on earth as it is in heaven, in fulfillment of the Lord's Prayer that "thy will be done on earth as it is in heaven". This notion is essentially the same as Quietism, which condemned as a heresy by Pope Innocent XI in 1687 in the papal bull Coelestis Pastor.
In his papal encyclical Spe Salvi, Pope Benedict XVI categorically ruled out the idea that the "kingdom of the good" could be definitively established on earth because of the permanent reality of human free will and original sin:

Since man always remains free and since his freedom is always fragile, the kingdom of good will never be definitively established in this world. Anyone who promises the better world that is guaranteed to last for ever is making a false promise; he is overlooking human freedom. Freedom must constantly be won over for the cause of good. Free assent to the good never exists simply by itself. If there were structures which could irrevocably guarantee a determined—good—state of the world, man's freedom would be denied, and hence they would not be good structures at all. (para 24)

The Divine Will Movement teaches that the establishment of this terrestrial paradise will be inaugurated on earth during a "Middle Coming" of Christ to reign with the resurrected saints for the duration of the Millennium of Rev 20. They closely follow the dual-antichrist eschatology of Joachim de Fiore, and posit the arrival of two separate antichrist figures, one before and one after the Millennium. The first antichrist figure will be slain by Christ during the event of the "Middle Coming" to establish the millennial reign on earth, and the final "tail/Gog" antichrist rises up to make one last assault against the Church at the end of the Millennium, when the forces of Satan once again surround the camp of the saints before the "Final Coming" of Christ in glory. This contradicts the most authorative account on the Antichrist given by the Church Doctor St. Robert Bellarmine, who teaches that there is only one Antichrist who comes at the very end of time, and that the opinion of Lactantius...(Read more.)
