Type: supporting argument (off-timeline) · Assessment: sound — that Gehenna = the lake of fire = the post-judgment eternal state, and that this final state is distinct from intermediate Hades/Sheol, is the patristic and scholarly mainstream, stated outright by Irenaeus and grounded in Rev 20:14 (where Hades itself is thrown into the lake of fire); the Gehenna = lake-of-fire equation is an inference, but a well-grounded and unrefuted one

A two-stage geography of the dead: Hades / Sheol is the present holding-place of the departed (where the rich man lifts up his eyes "in torments," Luke 16:23) — but it is intermediate and temporary. Gehenna, which Scripture also calls the lake of fire and the second death, is the post-judgment, eternal state — "hell" proper — into which the wicked are sent body and soul after the resurrection, and into which Hades itself is finally cast and abolished (Rev 20:14). The two are not the same place: Hades empties at the last judgment, Gehenna is filled.
The reading turns on disentangling words that English collapses: the King James and much popular usage render both Hades and Gehenna as "hell," fusing the intermediate and the final state into one. The claim is that the underlying terms denote two distinct things.
This is not a single proponent's thesis but the broad mainstream of patristic eschatology and of modern lexical/biblical scholarship, which routinely distinguishes Hades (the intermediate abode) from Gehenna / the lake of fire (the final). It is voiced in the afterlife-arc exposition that seeded this doctrine, and it is the standard correction offered against the popular conflation of the two under the one English word "hell." Its strongest ancient statements are Irenaeus and Hippolytus.
The distinction is well-anchored in the texts and stated explicitly by the early Fathers:1
What holds. The distinction between an intermediate Hades and a final fiery state is as firm as anything in this doctrine. Rev 20:14 cannot be read any other way: Hades is emptied and then thrown into the lake of fire, so the two are not identical, and the lake is the later, terminal state. The early Fathers say so plainly — Hippolytus keeps the lake of fire empty until judgment-day while Hades already detains souls; Irenaeus, the oldest clear voice, equates the lake of fire, the second death, and Gehenna outright. That English "hell" translates both Hades and Gehenna, blurring them, is a real lexical fact, and untangling it is sound exegesis, not novelty.
What is overstated or imprecise.2
Sound. That the final state of punishment (Gehenna / the lake of fire / the second death) is distinct from the intermediate Hades is the mainstream of both the patristic tradition and modern scholarship, and it follows directly from Rev 20:14, where Hades is emptied and then cast into the lake of fire — they cannot be the same place. Hippolytus keeps the fiery final state unoccupied until judgment while Hades already holds the dead, and Irenaeus equates the lake of fire, the second death, and Gehenna in so many words. The one genuinely inferential step — that the Synoptics' Gehenna and the Apocalypse's lake of fire name the same thing — is well grounded (both are the post-judgment eternal fire) and unrefuted, though no verse states the identity outright. Two things to keep clear, neither of which undercuts the distinction: English "hell" renders both Hades and Gehenna and so hides it, and the separate question of the lake of fire's nature (eternal torment vs. annihilation) is contested in its own right.

On Gehenna (Valley of Hinnom) and the Synoptic + James usage vs. the Apocalypse's lake of fire, and the absence of a single verse identifying the two, see the Gehenna sayings (Matt 5:22, 29–30; 18:9; 23:33; Luke 12:5; Jas 3:6) alongside Rev 19:20; 20:10, 14–15; 21:8.
