Eschatology

What Is Eschatology?

Eschatology is the branch of religious thought concerned with the “last things,” from the Greek eschatos, meaning “last” or “final.” In its broadest sense, eschatology asks what ultimately happens to the individual human being, to humanity collectively, and sometimes to the universe itself. It therefore includes such subjects as death, the survival of the soul, resurrection, final judgment, heaven and hell, the coming of a messiah or savior, the defeat of evil, and the ultimate destiny of creation.

It is useful to distinguish individual eschatology from universal eschatology. Individual eschatology concerns what happens to a person after death. Universal or historical eschatology concerns the destiny of the human race and the world, whether history is moving toward a culminating event in which evil is defeated and a transformed order appears. A related term, apocalypticism, refers more specifically to revelations concerning dramatic events preceding that transformation, wars, disasters, supernatural signs, Antichrist-like figures, messianic appearances, and cosmic upheaval. Thus all apocalyptic thinking is eschatological, but eschatology need not be apocalyptic.

Judaism, Christianity, and Islam share a particularly important characteristic: history is fundamentally linear rather than endlessly cyclical. Creation has a beginning, human history has moral meaning, God ultimately judges humanity, and history moves toward some form of consummation. Yet the importance and details of that consummation differ substantially among the traditions.

Jewish Eschatology

The earliest books of the Hebrew Bible contain surprisingly little systematic teaching about the end of the world or the afterlife. Early biblical religion concentrates heavily on life in this world, the covenant between God and Israel, obedience to divine law, the preservation of the people, justice, fertility, land, descendants, and national survival. The dead are sometimes described as going to Sheol, but this is not yet the elaborate heaven-and-hell system familiar from later Judaism and Christianity.

More explicit eschatological ideas appear comparatively late in the Hebrew Bible and become increasingly important during the Second Temple period. Daniel 12, for example, anticipates the awakening of the dead, with some rising to everlasting life and others to disgrace. Daniel 12:2 Rabbinic Judaism subsequently developed beliefs in the Messiah, resurrection of the dead, divine judgment, and Olam Ha-Ba, the “World to Come.” Traditional Judaism eventually regarded resurrection as sufficiently important that Maimonides included it among his Thirteen Principles of Faith. Background on Jewish resurrection beliefs

Jewish messianism generally anticipates a human descendant of King David who restores Israel, establishes justice, gathers the dispersed Jewish people, and inaugurates an era of peace and knowledge of God. Unlike Christianity, traditional Judaism does not normally identify the Messiah with God himself. Maimonides presented an especially naturalistic interpretation, the Messiah would be an extraordinary human ruler rather than a divine being performing spectacular supernatural miracles. Other Jewish traditions contain considerably more supernatural expectations. Background on Jewish messianism

Jewish thought also contains considerable disagreement about exactly what Olam Ha-Ba means. It can refer to the spiritual existence of the righteous after death, to the messianic age, or to the perfected existence following resurrection. Maimonides emphasized an ultimately spiritual existence, whereas Nahmanides envisioned a more enduring resurrected existence. Background on the World to Come

Consequently, Judaism possesses a genuine eschatology but historically has tended to place less emphasis on a detailed timetable of the end than Christianity or Islam. Modern Jewish movements also differ considerably. Orthodox Judaism generally retains traditional expectations of Messiah and resurrection, while Reform and other liberal Jewish traditions have often interpreted messianism as humanity's gradual movement toward a just and peaceful “messianic age” rather than the appearance of a particular supernatural redeemer.

Christian Eschatology

Christianity emerged from Jewish apocalyptic and messianic expectations but transformed them around one decisive proposition: Jesus was the Messiah, was resurrected from the dead, and will return.

Christian eschatology therefore has an unusual “already but not yet” structure. Christians believe that the decisive act of salvation has already occurred in the death and resurrection of Christ, but that history has not yet reached its completion. The final fulfillment comes with the Second Coming, or Parousia, of Christ.

Across Catholic, Orthodox, and most Protestant Christianity, the broad outline is remarkably consistent: Christ will return, the dead will be raised, humanity will be judged, evil and death will ultimately be defeated, and the righteous will enter eternal life with God. The New Testament explicitly connects resurrection with judgment, developing themes already present in Daniel. Daniel 12:2 and John 5:28–29 The Catholic Catechism summarizes Christian eschatology as encompassing death, judgment, resurrection of the body, heaven, hell, and the coming of Christ on the last day. Catechism of the Catholic Church

Christian traditions disagree much more vigorously about how the events preceding the end should be understood. The book of Revelation describes extraordinary symbolic events involving beasts, persecution, divine judgments, Satan's defeat, resurrection, and the establishment of a “new heaven and a new earth.” Christians have interpreted these passages in radically different ways. Some regard them primarily as symbolic representations of the perennial conflict between good and evil. Others expect relatively literal future events.

Particularly among some Protestant traditions, elaborate doctrines have developed concerning the Antichrist, the Tribulation, Armageddon, the millennium, and sometimes the Rapture. Other Christians, especially many Catholics, Orthodox Christians, and mainline Protestants, are much less inclined to construct chronological predictions from these passages.

The central Christian proposition nevertheless remains clear: history culminates not merely in human progress but through an act of God centered upon the return of Christ, resurrection, judgment, and the final conquest of death and evil.

Sunni Islamic Eschatology

Eschatology is extraordinarily prominent in Islam. The Qur'an repeatedly invokes the Day of Resurrection, Yawm al-Qiyāmah, divine judgment, paradise, hell, and personal accountability. Indeed, an entire Qur'anic surah is entitled Al-Qiyāmah, “The Resurrection.” Qur'an, Surah 75 Belief in the Last Day is part of the basic Islamic framework of faith.

In mainstream Sunni belief, death is followed by an intermediate condition generally called barzakh. Eventually God brings the present order of creation to an end. The dead are bodily resurrected and gathered before God. Every person's deeds are exposed and weighed, divine justice is rendered, and humanity is assigned its ultimate destiny in Jannah, paradise, or Jahannam, hell. Islamic theologians have debated details concerning the nature and duration of punishment and the precise character of resurrection, but bodily resurrection and judgment belong to the classical doctrinal core.

Sunni traditions also developed an elaborate collection of signs preceding the Hour. These commonly include widespread disorder and moral corruption, the appearance of al-Dajjāl, a great deceiver sometimes compared loosely with the Christian Antichrist, the return of Jesus, ʿĪsā, Gog and Magog, and extraordinary disturbances in the natural world.

Many Sunni traditions also anticipate the appearance of the Mahdi, “the rightly guided one,” who restores justice before the end. But here an important distinction from Twelver Shiism appears. The Mahdi is not identified in mainstream Sunni doctrine as an imam presently living in supernatural concealment. He is generally expected to arise in the future as a righteous human leader. Moreover, the Mahdi is not mentioned explicitly in the Qur'an, and his doctrinal importance has varied considerably among Sunni theologians and communities. Scholarship therefore cautions against treating every detail of Sunni apocalyptic tradition as universally agreed doctrine. Cambridge Companion discussion of Islamic eschatology

Jesus occupies an especially interesting position. Islam rejects the Christian doctrine that Jesus is divine, yet Islamic eschatological traditions give Jesus an important role near the end of history. In widespread Sunni accounts he returns, defeats the Dajjāl, vindicates true religion, and participates in the establishment of justice before the final resurrection and judgment.

Sunni Islamic eschatology is therefore strongly judicial: earthly life is a moral examination whose ultimate significance is revealed at resurrection and judgment.

Twelver Shiite Eschatology

Twelver Shiism shares Islam's fundamental doctrines of resurrection, judgment, paradise, hell, and the final sovereignty of God. What distinguishes it is the extraordinary importance assigned to the Mahdi and the Hidden Imam.

Twelver Shiites believe that legitimate spiritual authority passed through a succession of twelve Imams descended from Ali and Fatimah. The twelfth, Muhammad ibn Hasan al-Askari, is believed to have entered concealment or Occultation, ghayba, after the death of his father in the ninth century. The Lesser Occultation, during which he was believed to communicate through representatives, was followed in 940–941 by the Major Occultation, which Twelver doctrine holds continues to the present. Encyclopaedia Iranica on Shiite eschatology

The Hidden Imam is the Mahdi, the divinely guided figure who will eventually reappear. His return is not a peripheral belief but one of the defining characteristics of Twelver Shiism. Encyclopaedia Iranica describes Twelver eschatology as being exceptionally dominated by the expected return of the Hidden Imam. Encyclopaedia Iranica

The Mahdi appears in a world characterized by oppression, injustice, deception, and disorder. His mission is to defeat the forces of injustice and restore the authentic divine order. The earth is ultimately to be filled with justice rather than tyranny. In some Twelver traditions, the Mahdi's appearance is accompanied by dramatic conflicts and supernatural signs. Some traditions also contain the doctrine of rajʿa, the return to earthly life of certain exemplary righteous and wicked figures before the universal resurrection, allowing unresolved struggles between justice and oppression to reach their conclusion.

The Mahdi's victory, however, is not itself the final resurrection. Rather, his appearance transforms the final stage of human history and prepares creation for the ultimate resurrection and Last Judgment. Encyclopaedia Iranica on the Mahdi in Twelver Shiism

This gives Twelver Shiism an especially powerful historical eschatology. The suffering of the Imams, above all the martyrdom of Husayn at Karbala, is situated within a larger cosmic struggle between justice and oppression. History contains injustice that has not yet been rectified, but the return of the Mahdi guarantees its eventual reversal.

Eschatology in Other Religions

Eschatological thinking is by no means confined to Judaism, Christianity, and Islam. Zoroastrianism contains one of the world's oldest and most highly developed systems of universal eschatology. It anticipates a final victory of good over evil, resurrection of the dead, judgment, the appearance of a future beneficent figure or Saoshyant, and the final renovation of creation known as Frashokereti. Encyclopaedia Iranica on Zoroastrian eschatology Scholars have long debated the extent to which Persian religious concepts influenced Jewish thought during and after the Persian period and thereby indirectly influenced Christianity and Islam. The similarities are substantial, although the precise lines of historical borrowing remain disputed.

Hinduism also contains end-time concepts, but its conception of history is generally cyclical rather than linear. The universe passes through enormous cycles of creation, degeneration, destruction, and renewal. In Vaishnava traditions, Kalki, the final avatar of Vishnu, appears at the conclusion of the morally corrupt Kali Yuga, destroys wickedness, restores dharma, and inaugurates another age. This is eschatological in one sense, but it is not a single irreversible end of history.

Buddhism likewise possesses future-oriented expectations, especially the coming of Maitreya, the future Buddha, after the teachings of the historical Buddha have disappeared. Yet Buddhism ordinarily places much greater emphasis on liberation from the repeating cycle of birth and death than upon a single cosmic Last Judgment. Karma rather than judgment by a creator God determines the individual's future condition.

Other traditions contain comparable motifs. Norse religion possessed the dramatic mythology of Ragnarök, in which gods and destructive forces engage in a final battle followed by a renewed world. Some forms of Sikh, Jain, Chinese, and indigenous religious thought contain teachings concerning cosmic cycles, judgment, decline, renewal, or future spiritual transformation, but these generally occupy a less structurally central place than eschatology does in Christianity and Islam.

The Essential Comparison

The distinction between Sunni and Twelver Shiite eschatology is especially important. Sunnis may expect a Mahdi, but he is generally a future righteous leader whose precise identity is unknown and whose role is secondary to the universal resurrection and judgment. For Twelver Shiites, the Mahdi is already known, he is the twelfth Imam, believed to be alive in occultation and destined to return. His eventual manifestation provides Twelver Shiism with one of the most specific and politically resonant messianic expectations among the world's major religious traditions.

In that sense, eschatology is fundamentally a doctrine of ultimate justice, the belief that evil, suffering, injustice, and death do not have the final word.
