At the beginning of the millennium there will be a resurrection of the just, or the First Resurrection, and these will be "caught up" to meet the Savior. All others will have to wait until the end of the millennium to be raised, and that will comprise the Second Resurrection. I think the former is what your PB is talking about. The First Resurrection began with the Savior taking up His life again, and will end after the Resurrection of the Just during the millennium.
