CCC 677 The Church will enter the glory of the kingdom only through this final Passover, when she will follow her Lord in his death and Resurrection.1 The kingdom will be fulfilled, then, not by a historic triumph of the Church through a progressive ascendancy, but only by God’s victory over the final unleashing of evil, which will cause his Bride to come down from heaven.2 God’s triumph over the revolt of evil will take the form of the Last Judgment after the final cosmic upheaval of this passing world.3
