Intermediate state (Christianity) in the context of "Soul death"

Eternal life traditionally refers to continued life after death, as outlined in Christian eschatology. The Apostles' Creed testifies: "I believe... the resurrection of the body, and life everlasting." In this view, eternal life commences after the Second Coming of Jesus Christ and the resurrection of the dead, although in the New Testament's Johannine literature there are references to eternal life commencing in the earthly life of the believer, possibly indicating an inaugurated eschatology.

According to mainstream Christian theology, after death but before the Second Coming, the saved live with God in an intermediate state, but after the Second Coming, experience the physical resurrection of the dead and the physical recreation of a New Earth. The Catechism of the Catholic Church states, "By death the soul is separated from the body, but in the resurrection God will give incorruptible life to our body, transformed by reunion with our soul. Just as Christ is risen and lives for ever, so all of us will rise at the last day." N.T. Wright argues that "God's plan is not to abandon this world... Rather, he intends to remake it. And when he does, he will raise all people to new bodily life to live in it. That is the promise of the Christian gospel."

Purgatory (Latin: purgatorium, borrowed into English via Anglo-Norman and Old French) is a belief in Catholic theology. It is a passing intermediate state after physical death for purifying or purging a soul before entering Heaven. A common analogy is dross being removed from gold in a furnace.

In Catholic doctrine, purgatory refers to the final cleansing of those who died in the State of Grace, and leaves in them only "the holiness necessary to enter the joy of heaven"; it is entirely different from the punishment of the damned and is not related to the forgiveness of sins for salvation. A forgiven person can be freed from his "unhealthy attachment to creatures" by fervent charity in this world, and otherwise by the non-vindictive "temporal (i.e. non-eternal) punishment" of purgatory.

Religions with the belief in a final judgment, a resurrection of the dead or an intermediate state (such as Hades or purgatory) often offer prayers on behalf of the dead to God.

Hades, according to various Christian denominations, is "the place or state of departed spirits", borrowing the name of Hades, the name of the underworld in Greek mythology. It is often associated with the Jewish concept of Sheol. In Christian theology, Hades is seen as an intermediate state between Heaven and Hell in which the dead enter and will remain until the Last Judgment.

Adventism is a branch of Protestant Christianity that believes in the imminent Second Coming (or the "Second Advent") of Jesus Christ. It originated in the 1830s in the United States during the Second Great Awakening when Baptist preacher William Miller first publicly shared his belief that the Second Coming would occur at some point between 1843 and 1844. His followers became known as Millerites. After Miller's prophecies failed, the Millerite movement split up and was continued by a number of groups that held different doctrines from one another, being Ellen G. White the best known leader and writer. These groups, stemming from a common Millerite ancestor, collectively became known as the Adventist movement.

Although the Adventist churches hold much in common with mainline Christianity, their theologies differ on whether the intermediate state of the dead is unconscious sleep or consciousness, whether the ultimate punishment of the wicked is annihilation or eternal torment, the nature of immortality, whether the wicked are resurrected after the millennium, and whether the sanctuary of Daniel 8 refers to the one in heaven or one on earth. Seventh-day Adventists and some smaller Adventist groups observe the seventh day Sabbath. The General Conference of Seventh-day Adventists has compiled that church's core beliefs in the 28 Fundamental Beliefs (1980 and 2005).

Barzakh (Arabic: برزخ) is an Arabic word meaning "obstacle", "hindrance", "separation", or "barrier". In Islamic eschatology, it denotes a barrier separating the world of humans (heaven, earth, underworld) from the world of spirits. It can also refer to a phase/"stage" between an individual's death and their resurrection in "the Hereafter". It is also considered as a place where souls rest until the day of judgement. It bears resemblance to the intermediate state in Christianity.

Some scholars believe that good Muslims will have a heavenly experience during this time, and sinners will experience suffering; while some Shia scholars believe the experience will not be like the physical pain or pleasure of the temporal world.
