1024 This perfect life with the Most Holy Trinity – this communion of life and love with the Trinity, with the Virgin Mary, the angels and all the blessed – is called “heaven.” Heaven is the ultimate end and fulfillment of the deepest human longings, the state of supreme, definitive happiness.
1025 To live in heaven is “to be with Christ.” The elect live “in Christ,”600 but they retain, or rather find, their true identity, their own name.601For life is to be with Christ; where Christ is, there is life, there is the kingdom.602
1026 By his death and Resurrection, Jesus Christ has “opened” heaven to us. The life of the blessed consists in the full and perfect possession of the fruits of the redemption accomplished by Christ. He makes partners in his heavenly glorification those who have believed in him and remained faithful to his will. Heaven is the blessed community of all who are perfectly incorporated into Christ.
1027 This mystery of blessed communion with God and all who are in Christ is beyond all understanding and description. Scripture speaks of it in images: life, light, peace, wedding feast, wine of the kingdom, the Father’s house, the heavenly Jerusalem, paradise: “no eye has seen, nor ear heard, nor the heart of man conceived, what God has prepared for those who love him.”603
1028 Because of his transcendence, God cannot be seen as he is, unless he himself opens up his mystery to man’s immediate contemplation and gives him the capacity for it. The Church calls this contemplation of God in his heavenly glory “the beatific vision”: How great will your glory and happiness be, to be allowed to see God, to be honored with sharing the joy of salvation and eternal light with Christ your Lord and God, . . . to delight in the joy of immortality in the Kingdom of heaven with the righteous and God’s friends.604
1029 In the glory of heaven the blessed continue joyfully to fulfill God’s will in relation to other men and to all creation. Already they reign with Christ; with him “they shall reign for ever and ever.”605
The chapters in this little book come from several of Mother Angelica’s episodes on her show. It is beautifully put together, using her own words. It makes us desire heaven all the more. I think every Christian should read it.
670 Since the Ascension God’s plan has entered into its fulfillment. We are already at “the last hour”.554 “Already the final age of the world is with us, and the renewal of the world is irrevocably under way; it is even now anticipated in a certain real way, for the Church on earth is endowed already with a sanctity that is real but imperfect.”555 Christ’s kingdom already manifests its presence through the miraculous signs that attend its proclamation by the Church.556
. . .until all things are subjected to him
671 Though already present in his Church, Christ’s reign is nevertheless yet to be fulfilled “with power and great glory” by the King’s return to earth.557This reign is still under attack by the evil powers, even though they have been defeated definitively by Christ’s Passover.557 Until everything is subject to him, “until there be realized new heavens and a new earth in which justice dwells, the pilgrim Church, in her sacraments and institutions, which belong to this present age, carries the mark of this world which will pass, and she herself takes her place among the creatures which groan and travail yet and await the revelation of the sons of God.”559 That is why Christians pray, above all in the Eucharist, to hasten Christ’s return by saying to him:560 Marana tha! “Our Lord, come!”561
2816 In the New Testament, the word basileia can be translated by “kingship” (abstract noun), “kingdom” (concrete noun) or “reign” (action noun). The Kingdom of God lies ahead of us. It is brought near in the Word incarnate, it is proclaimed throughout the whole Gospel, and it has come in Christ’s death and Resurrection. The Kingdom of God has been coming since the Last Supper and, in the Eucharist, it is in our midst. The kingdom will come in glory when Christ hands it over to his Father: It may even be . . . that the Kingdom of God means Christ himself, whom we daily desire to come, and whose coming we wish to be manifested quickly to us. For as he is our resurrection, since in him we rise, so he can also be understood as the Kingdom of God, for in him we shall reign.86
2817 This petition is “Marana tha,” the cry of the Spirit and the Bride: “Come, Lord Jesus.” Even if it had not been prescribed to pray for the coming of the kingdom, we would willingly have brought forth this speech, eager to embrace our hope. In indignation the souls of the martyrs under the altar cry out to the Lord: “O Sovereign Lord, holy and true, how long before you judge and avenge our blood on those who dwell upon the earth?” For their retribution is ordained for the end of the world. Indeed as soon as possible, Lord, may your kingdom come!87
2818 In the Lord’s Prayer, “thy kingdom come” refers primarily to the final coming of the reign of God through Christ’s return.88 But, far from distracting the Church from her mission in this present world, this desire commits her to it all the more strongly. Since Pentecost, the coming of that Reign is the work of the Spirit of the Lord who “complete[s] his work on earth and brings us the fullness of grace.”89
2819 “The kingdom of God [is] righteousness and peace and joy in the Holy Spirit.”90 The end-time in which we live is the age of the outpouring of the Spirit. Ever since Pentecost, a decisive battle has been joined between “the flesh” and the Spirit.91Only a pure soul can boldly say: “Thy kingdom come.” One who has heard Paul say, “Let not sin therefore reign in your mortal bodies,” and has purified himself in action, thought and word will say to God: “Thy kingdom come!”92
