Is Hell Eternal? What Judaism, Christianity, and Islam Teach

Judaism's answer to whether hell is eternal is, frankly, complicated—and that complexity is a feature, not a bug, of Jewish theological reasoning. The Hebrew Bible uses the term Sheol (שְׁאוֹל), a shadowy underworld to which all the dead descend, without strong moral differentiation. Isaiah 5:14 describes Sheol enlarging itself to swallow the proud and the multitudes Isaiah 5:14, but this is poetic imagery of death's appetite, not a doctrine of eternal punishment.

The later rabbinic concept of Gehenna (derived from the Valley of Hinnom outside Jerusalem) is far more relevant to the hell question. The Talmud, particularly tractate Rosh Hashanah (17a), teaches that most souls spend no more than twelve months in Gehenna undergoing purification before ascending to Olam Ha-Ba (the World to Come). This is a fundamentally purgatorial model, not an eternal one. Rabbi Joseph Karo's 16th-century legal code, the Shulchan Aruch, reflects this consensus.

There are minority voices. Some medieval authorities, influenced by Maimonides (1138–1204), argued that the wicked are simply annihilated—their souls cease to exist—rather than tormented forever. A small number of texts do suggest that the most egregious sinners (e.g., heretics, informers) face a more permanent fate, but this is not the dominant view. The overwhelming rabbinic consensus is that Gehenna is temporary and remedial, not eternal and punitive.

It's worth noting that Judaism never developed the same systematic, creedal doctrine of hell that Christianity did. Eschatology is relatively underemphasized compared to law and ethics in Jewish thought.

Christianity is arguably the tradition most internally divided on this question, and the debate has intensified in recent decades. Three main positions compete for theological space.

Eternal Conscious Torment (ECT) is the traditional view, held by Augustine (354–430), Thomas Aquinas (1225–1274), and affirmed in the Westminster Confession (1646). Matthew 25:46 is the cornerstone text: 'And these shall go away into everlasting punishment: but the righteous into life eternal.' The symmetry of 'everlasting punishment' and 'eternal life' in the same verse is taken as decisive proof that hell's duration mirrors heaven's.

Annihilationism (or conditional immortality) argues that the unsaved are ultimately destroyed rather than tormented forever. Scholars like John Stott (1921–2011) and Edward Fudge (1944–2017) championed this view, arguing that 'eternal punishment' refers to an eternal result—permanent death—not an eternal process. The soul isn't inherently immortal; immortality is a gift to the redeemed.

Christian Universalism holds that all souls are eventually reconciled to God. Origen of Alexandria (c. 184–253) was its earliest major proponent, and modern theologians like David Bentley Hart have revived it. This view reads 'eternal' (Greek: aionios) as 'age-long' rather than strictly endless.

The retrieved passages don't include a direct New Testament citation on this, so the specific textual debate around Matthew 25:46 or Revelation 20:10 can't be fully quoted here. What's clear is that Christianity has no single, universally binding answer—denominations and theologians genuinely disagree.

Islam's scriptural witness on hell's eternity is among the most explicit of the three traditions. The Qur'an states directly: 'Indeed, the criminals will be in the punishment of Hell, abiding eternally' Quran 43:74. The Arabic word used is khālidīn (خَالِدِينَ), meaning 'dwelling permanently' or 'abiding forever'—a term repeated dozens of times across the Qur'an in reference to both paradise and hell.

Qur'an 20:74 adds a striking dimension: in hell, the guilty soul 'will neither die nor live' Quran 20:74—a state of perpetual, unresolved torment that is neither the mercy of death nor the joy of life. Hell itself is described as lying in wait, ready and prepared Quran 78:21, suggesting its permanence is built into the cosmic order.

That said, classical Islamic scholarship does contain a significant minority debate. Ibn Taymiyya (1263–1328) and his student Ibn al-Qayyim (1292–1350) argued—controversially—that hell may eventually be extinguished for Muslims who sinned but were not polytheists, and some extended this to all souls. This position (fanāʾ al-nār, the 'annihilation of the Fire') was considered heterodox by the majority of Sunni scholars, including the Ash'ari and Maturidi schools, who affirm hell's eternal duration for unbelievers.

The mainstream Sunni position, reflected in creeds like the Tahawiyya (c. 900 CE), is that hell is eternal for disbelievers (kuffār), while sinful Muslims may eventually be removed after a period of punishment. So even within the tradition that most clearly affirms eternal hell, there's nuance about who stays forever.

Isaiah depicts judgment with stark imagery: “hell has enlarged herself … and [the proud] shall descend into it,” which shows divine judgment but does not specify the duration of punishment for the wicked Isaiah 5:14.

Foundational passages emphasize that God is everlasting and sovereign—an eternal judge—without directly defining the temporality of hell’s punishments in these texts alone Jeremiah 10:10Isaiah 40:28. Taken together, the cited verses affirm judgment and God’s eternity but do not themselves declare hell to be eternal or temporary Isaiah 5:14Jeremiah 10:10Isaiah 40:28.

In the Christian Old Testament (shared with Judaism), Isaiah’s line about the proud descending when “hell has enlarged herself” presents judgment but, by itself, does not state whether the punishment is everlasting Isaiah 5:14.

These same Scriptures stress that God is eternal—“the everlasting Sovereign” who “never grows faint or weary”—yet these affirmations of God’s eternity do not, on their own, settle the question of hell’s duration in the cited passages Jeremiah 10:10Isaiah 40:28. Thus, from these texts alone, the eternality of hell is not made explicit Isaiah 5:14Jeremiah 10:10Isaiah 40:28.

The Qur’an speaks directly: “the criminals will be in the punishment of Hell, abiding eternally,” which indicates everlasting punishment for at least some denizens of Hell Quran 43:74. It also says of the guilty there: “He will neither die nor live,” pointing to an ongoing, inescapable state Quran 20:74. Another verse declares that Hell has been “lying in wait,” underscoring its assured reality in the divine plan Quran 78:21.

On this textual basis, the Qur’an explicitly presents Hell as eternal for some, with no prospect of death or relief in that state Quran 43:74Quran 20:74Quran 78:21.
