Catechism on “new heavens and a new earth”
1042 At the end of time, the Kingdom of God will come in its fullness. After the universal judgment, the righteous will reign for ever with Christ, glorified in body and soul. The universe itself will be renewed:
The Church . . . will receive her perfection only in the glory of heaven, when will come the time of the renewal of all things. At that time, together with the human race, the universe itself, which is so closely related to man and which attains its destiny through him, will be perfectly re-established in Christ. 631
1043 Sacred Scripture calls this mysterious renewal, which will transform humanity and the world, “new heavens and a new earth.” 632 It will be the definitive realization of God’s plan to bring under a single head “all things in [Christ], things in heaven and things on earth.” 633
1044 In this new universe, the heavenly Jerusalem, God will have his dwelling among men. 634 “He will wipe away every tear from their eyes, and death shall be no more, neither shall there be mourning nor crying nor pain any more, for the former things have passed away.” 635
