Jon, I am not a scholar in Eschatology but Antichrist is going to reign before the Second Coming of Christ or The End of the World, not before the "first resurrection". There has to be only ONE resurrection of the dead, and it is going to be after Second Coming for the Judgement Day. Not sure where the thousand years fit here and as far as I remember milleniarism is actually not recognized by Catholic Church, even considered a heresy, but is popular among Protestants and Zoroastrians. Good and sound explanations with diagram: http://www.catholicapologetics.org/ap090000.htm In Catholic Church( and the same is in Orthodox) the teaching is that after Ascension Jesus Christ will come one time - for the Last Judgement. There is no space for thousand years of peace and millenial reiign so on. It is actually a very interesting question and I suspect the eschatological blurriness of the vision of the End Times from many apparitions are the reasons why many of them are not recognized.
