Christianity
Christianity began as one of many Jewish apocalyptic and reform movements active in Palestine in the 1st century ce. These groups shared an intense conviction that the new heavens and new earth prophesied by Isaiah (Isaiah 65:17) were close at hand. They believed that history would soon find its consummation in a world perfected, when the nations would be judged, the elect redeemed, and Israel restored.
Jewish and Christian conceptions of heaven developed side by side, drawing from shared biblical and Greco-Roman sources. The liturgy of Temple, synagogue, and eucharistic service informed images of heaven, for in worship the community symbolically ascends to the heavenly Jerusalem, a realm of perpetual adoration and intercession for the needs of the world, where angels never cease to sing “Holy, holy, holy is the LORD of hosts” (Isaiah 6:3).
Christians believe that the estrangement between heaven and earth ended with the Incarnation, Passion, Resurrection, and Ascension of Christ: “in Christ God was reconciling the world to himself” (2 Corinthians 5:19). Sharing in Christ’s deathless divine life are the members of his mystical body, the church (Greek: ekklēsia), which is the communion of saints both living and dead. The Virgin Mary, regarded as Queen of Heaven, tirelessly intercedes for the faithful, including sinners who seek her protection.
Traditional Christian theology teaches that communion with God is the chief end for which human beings were made and that those who die in a state of grace are immediately (or after a period of purification) admitted to the bliss of heaven, where they become like God (1 John 3:2), see God face to face (1 Corinthians 13:12), and see all things in God. With the resurrection of the dead, beatitude will embrace the whole person—body, soul, and spirit. The social dimension of this beatitude is expressed in the last book of the New Testament, Revelation to John, with its vision of the blessed multitudes adoring God, who dwells in their midst, in a city of bejeweled splendour (21–22). Worship, fellowship, and creative pursuits all form part of the composite Christian picture of heaven, but the emphasis on domestic happiness and never-ending spiritual progress in heaven is largely a modern innovation.
