Satanus, Orthodox eschatology holds the 1,000 year reign of Christ as a past event, therefore, the apostasy follows while Satan rules unrestricted. Suffering is expected. Unlike Evangelicals, which are basically Christian Jihadists fighting wars for fleshly Israel and very focused on money and material gain, the Orthodox, and Catholic, are focused on piety and charity. This will remain despite the lack of Christian hegemony.
Is it coincidence that the Kabbalah (Occultism) and the Reformation surged following approximately 1,000 years since Chist came to Earth? Christianity dominated the world from shortly after Christ's death to about the 12th century. Even thereafter, Christianity remained dominant, although corrupted and co-opted. But for those 1,000 years, things were pretty good. Doctrine was pure, the gospel was brought to the four corners of the Earth.
As far as the future is concerned, Satanus, I believe we are experiencing cultural decline at an ever increasing rate. Everything is become very bland, stale, and dark. But what would one expect when everything of value is being dispensed with in the name of progress? We are slowly inching towards a world totalitarian system, which we are unlikely to ever recover from. 1984 is here and will get worse.
