ImmortalityImmortality is the concept of eternal life. Some modern species may possess biological immortality. Some scientists, futurists, and philosophers have theorized about the immortality of the human body, with some suggesting that human immortality may be achievable in the first few decades of the 21st century with the help of certain technologies such as mind uploading (digital immortality). Other advocates believe that life extension is a more achievable goal in the short term, with immortality awaiting further research breakthroughs.
Last JudgmentThe Last Judgment, Final Judgment, Day of Reckoning, Day of Judgment, Judgment Day, Doomsday, Day of Resurrection or The Day of the Lord (יום הדין; یوم القيامة or یوم الدین) is part of the Abrahamic religions and the Frashokereti of Zoroastrianism. Christianity considers the Second Coming of Jesus Christ to entail the final judgment by God of all people who have ever lived, resulting in the approval of some and the penalizing of most. The concept is found in all the canonical gospels, particularly in the Gospel of Matthew.
ResurrectionResurrection or anastasis is the concept of coming back to life after death. In a number of religions, a dying-and-rising god is a deity which dies and is resurrected. Reincarnation is a similar process hypothesized by other religions, which involves the same person or deity coming back to a body, rather than the different one. Disappearance of a body is another similar, but distinct, belief in some religions. With the advent of written records, the earliest known recurrent theme of resurrection was in Egyptian and Canaanite religions, which had cults of dying-and-rising gods such as Osiris and Baal.
EschatologyEschatology (ˌɛskəˈtɒlədʒi; ) concerns expectations of the end of the present age, human history, or the world itself. The end of the world or end times is predicted by several world religions (both Abrahamic and non-Abrahamic), which teach that negative world events will reach a climax. Belief that the end of the world is imminent is known as apocalypticism, and over time has been held both by members of mainstream religions and by doomsday cults.
PurgatoryPurgatory ( purgatorium, borrowed into English via Anglo-Norman and Old French) is, according to the belief of some Christian denominations and Islam, an intermediate state after physical death for expiatory purification. The process of purgatory is the final purification of the elect, which is entirely different from the punishment of the damned. Tradition, by reference to certain texts of scripture, sees the process as involving a cleansing fire. Some forms of Western Christianity, particularly within Protestantism, deny its existence.
SupernaturalSupernatural refers to phenomena or entities that are beyond the laws of nature. The term is derived from Medieval Latin supernaturalis, from Latin super- (above, beyond, or outside of) + natura (nature). Though the corollary term "nature", has had multiple meanings since the ancient world, the term "supernatural" emerged in the Middle Ages and did not exist in the ancient world. The supernatural is featured in folklore and religious contexts, but can also feature as an explanation in more secular contexts, as in the cases of superstitions or belief in the paranormal.
LimboIn Catholic theology, Limbo (limbus, or , referring to the edge of Hell) is the afterlife condition of those who die in original sin without being assigned to the Hell of the Damned. Medieval theologians of Western Europe described the underworld ("hell", "hades", "infernum") as divided into three distinct parts: Hell of the Damned, Limbo of the Fathers or Patriarchs, and Limbo of the Infants. The Limbo of the Fathers is an official doctrine of the Catholic Church, but the Limbo of the Infants is not.
JahannamIn Islam, Jahannam is the place of punishment for unbelievers and other evildoers in the afterlife, or hell. This notion is an "integral part of Islamic theology", and has "occupied an important place in the Muslim belief". It is often called by the proper name Jahannam. Simultaneously, jahannam is a term specifically for the uppermost layer of hell. The importance of Hell in Islamic doctrine is that it is an essential element of the Day of Judgment, which is one of the six articles of faith (belief in God, angels, books, prophets, the Day of Resurrection and providence) "by which the Muslim faith is traditionally defined.
Intermediate state (Christianity)In some forms of Christianity the intermediate state or interim state is a person's existence between death and the universal resurrection. In addition, there are beliefs in a particular judgment right after death and a general judgment or last judgment after the resurrection. Early Christians looked for an imminent end of the world and many of them had little interest in an interim state between death and resurrection.
Spirit world (Spiritualism)The spirit world, according to Spiritualism, is the world or realm inhabited by spirits, both good or evil of various spiritual manifestations. This spirit world is regarded as an external environment for spirits. The Spiritualism religious movement in the nineteenth century espoused a belief in an afterlife where individual's awareness persists beyond death. Although independent from one another, both the spirit world and the physical world are in constant interaction.
