In Christianity, heaven is traditionally the location of the throne of God as well as the holy angels. In traditional Christianity, it is considered to be a physical place in the afterlife. In most forms of Christianity, Heaven is also understood as the abode for the righteous dead in the afterlife, usually a temporary stage before the resurrection of the dead and the saints' return to the New Earth.
In the Book of Acts, the resurrected Jesus ascends to heaven where, as the Nicene Creed states, he now sits at the right hand of God and will return to Earth in the Second Coming. Various people have been said to have entered heaven while still alive, including Enoch, Elijah and Jesus himself, after his resurrection. According to Catholic, Eastern Orthodox, and Oriental Orthodox teaching, Mary, the mother of Jesus, is also said to have been assumed into heaven and is titled the Queen of Heaven.
In the Christian Bible, concepts about the future "Kingdom of Heaven" are professed in several scriptural prophecies of the new (or renewed) Earth said to follow the resurrection of the dead—particularly the books of Isaiah and Revelation and other sources of Christian eschatology.
The 1st century early Jewish-Christians, from whom Christianity developed as a Gentile religion, believed that the Kingdom of God was coming to Earth within their own lifetimes, and looked forward to a divine future on Earth. According to Bart Ehrman, when the Kingdom of God did not arrive, Christians beliefs gradually changed into the expectation of an immediate reward in heaven after death, rather than to a future divine kingdom on Earth, despite the churches' continuing to use the major creeds' statements of belief in a coming resurrection day and world to come.
The earliest of the Apostolic Fathers, Clement of Rome, does not mention entry into Heaven after death but instead expresses belief in the resurrection of the dead after a period of "slumber" at the Second Coming.
A fragment from the early 2nd century of one of the lost volumes of Papias, a Christian bishop, expounds that "heaven" was separated into three distinct layers. He referred to the first as just "heaven", the second as "paradise", and the third as "the city". Papias taught that "there is this distinction between the habitation of those who produce a hundredfold, and that of those who produce sixty-fold, and that of those who produce thirty-fold".
Eastern Orthodox cosmology

Eastern Orthodox cosmology perceives heaven as having different levels (John 14:2), the lowest of which is Paradise. At the time of creation, paradise touched the earth at the Garden of Eden. After the Fall of man, paradise was separated from the earth, and mankind forbidden entry, lest he partake of the Tree of Life and live eternally in a state of sinfulness (Genesis 3:22-24). At his death on the Cross, the Orthodox believe Jesus opened the door to Paradise to mankind again (Luke 23:43), and the Good Thief was the first to enter.
Various saints have had visions of heaven (2 Corinthians 12:2-4). The Orthodox concept of life in heaven is described in one of the prayers for the dead: "…a place of light, a place of green pasture, a place of repose, from whence all sickness, sorrow and sighing are fled away".
However, in the Eastern Orthodox and Oriental Orthodox, it is only God who has the final say on who enters heaven. In the Eastern Orthodox Church, heaven is part and parcel of deification (Theosis), the eternal sharing of the divine qualities through communion with the Triune God (reunion of Father and Son through love).

The Catholic Church teaches that "heaven is the ultimate end and fulfillment of the deepest human longings, the state of supreme, definitive happiness". In heaven one experiences the beatific vision. The church holds that,
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... Heaven is the blessed community of all who are perfectly incorporated into Christ.
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' (Rev 22:5).
The 'heaven' or 'happiness' in which we will find ourselves is neither an abstraction nor a physical place in the clouds, but a living, personal relationship with the Holy Trinity. It is our meeting with the Father which takes place in the risen Christ through the communion of the Holy Spirit.
Pope Benedict XVI gave this explanation of what is meant by heaven:
We all experience that when people die they continue to exist, in a certain way, in the memory and heart of those who knew and loved them. We might say that a part of the person lives on in them but it resembles a "shadow" because this survival in the heart of their loved ones is destined to end. God, on the contrary, never passes away and we all exist by virtue of his love. We exist because he loves us, because he conceived of us and called us to life. We exist in God's thoughts and in God's love. We exist in the whole of our reality, not only in our "shadow". Our serenity, our hope and our peace are based precisely on this: in God, in his thoughts and in his love, it is not merely a "shadow" of ourselves that survives but rather we are preserved and ushered into eternity with the whole of our being in him, in his creator love. It is his Love that triumphs over death and gives us eternity and it is this love that we call "Heaven": God is so great that he also makes room for us. And Jesus the man, who at the same time is God, is the guarantee for us that the being-man and the being-God can exist and live, the one within the other, for eternity.
According to Pope John Paul II,
The New Testament amplifies the idea of heaven in relation to the mystery of Christ. To show that the Redeemer's sacrifice acquires perfect and definitive value, the Letter to the Hebrews says that Jesus "passed through the heavens" (Heb. 4:14), and "entered, not into a sanctuary made with hands, a copy of the true one, but into heaven itself" (ibid., 9:24). Since believers are loved in a special way by the Father, they are raised with Christ and made citizens of heaven... After the course of our earthly life, participation in complete intimacy with the Father thus comes through our insertion into Christ's paschal mystery..."
The Catechism of the Catholic Church indicates several images of heaven found in the Bible:
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'."
Some denominations teach that one enters heaven at the moment of death, while others teach that this occurs at a later time (the Last Judgment). Some Christians maintain that entry into Heaven awaits such time as "When the form of this world has passed away."
Two related and often confused concepts of heaven in Christianity are better described as the "resurrection of the body" as contrasted with "the immortality of the soul". In the first, the soul does not enter heaven until the last judgement or the "end of time" when it (along with the body) is resurrected and judged. In the second concept, the soul goes to a heaven on another plane immediately after death. These two concepts are generally combined in the doctrine of the double judgement where the soul is judged once at death and goes to a temporary heaven, while awaiting a second and final judgement at the end of the world.
Some teach that death itself is not a natural part of life, but was allowed to happen after Adam and Eve disobeyed God so that mankind would not live forever in a state of sin and thus a state of separation from God.
Not only will the believers spend eternity with God, they will also spend it with each other. Revelation describes a New Jerusalem which comes from Heaven to the New Earth, which is seen to be a symbolic reference to the people of God living in community with one another.
The Seventh-day Adventist understanding of heaven is:
- That heaven is a material place where God resides.
- That God sent his son, Jesus Christ to earth to live as a human being, but who "perfectly exemplified the righteousness and love of God. By His miracles He manifested God's power and was attested as God's promised Messiah. He suffered and died voluntarily on the cross for our sins and in our place, was raised from the dead, and ascended to minister in the heavenly sanctuary in our behalf."
- That Christ promises to return as saviour at which time he will resurrect the righteous dead and gather them along with the righteous living to heaven. The unrighteous will die at Christ's second coming.
- That after Christ's second coming there will exist a period of time known as the Millennium during which Christ and his righteous saints will reign and the unrighteous will be judged. At the close of the Millennium, Christ and his angels return to earth to resurrect the dead that remain, to issue the judgements and to forever rid the universe of sin and sinners.
- "On the new earth, in which righteousness dwells, God will provide an eternal home for the redeemed and a perfect environment for everlasting life, love, joy, and learning in His presence. For here God Himself will dwell with His people, and suffering and death will have passed away. The great controversy will be ended, and sin will be no more. All things, animate and inanimate, will declare that God is love; and He shall reign forever." It is at this point that heaven is established on the new earth.
Jehovah's Witnesses believe that heaven is the dwelling place of Jehovah and his spirit creatures. They believe that only 144,000 chosen faithful followers ("The Anointed") will be resurrected to heaven to rule with Christ over the majority of mankind who will live on Earth.
Latter Day Saint movement
The view of heaven according to the Latter Day Saint movement is based on section 76 of the Doctrine and Covenants as well as 1 Corinthians 15 in the King James Version of the Bible. The afterlife is divided first into two levels until the Last Judgement; afterwards it is divided into four levels, the upper three of which are referred to as "degrees of glory" that, for illustrative purposes, are compared to the brightness of heavenly bodies: the sun, moon, and stars.
Before the Last Judgment, spirits separated from their bodies at death go either to paradise or to spirit prison dependent on if they had been baptised and confirmed by the laying on of hands. Paradise is a place of rest while its inhabitants continue learning in preparation for the Last Judgement. Spirit Prison is a place of learning for the wicked and unrepentant and those who were not baptised; however, missionary efforts done by spirits from Paradise enable those in Spirit Prison to repent, accept the gospel and the atonement and receive baptism through the practice of baptism for the dead.
After the resurrection and Last Judgement, people are sent to one of four levels:
- The Celestial Kingdom is the highest level, with its power and glory comparable to the sun. Here, faithful and valiant disciples of Christ who accepted the fullness of his gospel and kept their covenants with Him through following the prophets of their dispensation are reunited with their families and with God the Father, Jesus Christ, and the Holy Spirit for all eternity. Those who would have accepted the gospel with all their hearts had they been given the opportunity in life (as judged by Christ and God the Father) are also saved in the Celestial Kingdom. Latter-Day Saint movements do not believe in the concept of original sin, but believe children to be innocent through the atonement. Therefore, all children who die before the age of accountability inherit this glory. Men and women who have entered into celestial marriage are eligible, under the tutelage of God the Father, to eventually become gods and goddesses as joint-heirs with Jesus Christ.
- The Terrestrial Kingdom's power and glory is comparable to that of the moon, and is reserved for those who understood and rejected the full gospel in life but lived good lives; those who did accept the gospel but failed to keep their covenants through continuing the process of faith, repentance, and service to others; those who "died without law" (D & C 76:72) but accepted the full gospel and repented after death due to the missionary efforts undertaken in Spirit Prison. God the Father does not come into the Terrestrial Kingdom, but Jesus Christ visits them and the Holy Spirit is given to them.
- The Telestial Kingdom is comparable to the glory of the stars. Those placed in the Telestial Kingdom suffered the pains of Hell after death because they were liars, murderers, adulterers, whoremongers, etc. They are eventually rescued from Hell by being redeemed through the power of the atonement at the end of the Millennium. Despite its far lesser condition in eternity, the Telestial Kingdom is described as being more comfortable than Earth in its current state. Suffering is a result of a full knowledge of the sins and choices which have permanently separated a person from the utter joy that comes from being in the presence of God and Jesus Christ, though they have the Holy Spirit to be with them.
- The Outer darkness is the lowest level and has no glory whatsoever. It is reserved for Satan, his angels, and those who have committed the unpardonable sin. This is the lowest state possible in the eternities, and one that very few people born in this world attain, since the unpardonable sin requires that a person know with a perfect knowledge that the gospel is true and then reject it and fight defiantly against God. The only known son of Perdition is Cain, but it is generally acknowledged that there are probably more scattered through the ages.
