The concept of FireAndBrimstoneHell comes from a distinction LostInTranslation. The word "Hell" is used as a translation for four words used in the initial writing of ''Literature/TheBible'' in its original languages: ''Sheol'', ''Hades'', ''Tartarus'', and ''Gehenna''. ''Sheol'' is a Hebrew word and ''Hades'' is Greek; both mean the same thing, the abode of the dead for all humans, whether good or bad, at least until the end of days, and used in conjunction with Ecclesiastes 9:5 would refer to CessationOfExistence. ''Hades'' is mentioned as a place of torment only once: in Luke 16:19-31, Jesus tells a story about a rich man who died and went there (however, this was a parable, so whether he meant it literally is up for debate). ''Tartarus'' is used only once:

-->God did not hold back from punishing the angels that sinned, but, by throwing them into Tartarus, delivered them to pits of dense darkness to be reserved for judgment. (2 Peter 2:4)

Note that this is in past tense, and the phrase "reserved for judgment" denotes that that this is not the final fate for the {{Fallen Angel}}s referred to. ''Gehenna'' is a Greek word that when translated means "Valley of Hinnom", which was a trash dump where garbage, filth, corpses of criminals, and the like were burned. Jesus re-purposed this word to refer to the future eventual end and KarmicDeath of the wicked. Unfortunately, the ''King James Version'' translated ALL FOUR words as "Hell", despite ''Hades'' and ''Gehenna'' having different meanings and thus causing some confusion, especially considering the KJV's long-standing use and popularity. Recent Bible translations have caught on to this error and make some attempts to correct it, but it's too little, too late to reverse the popular notion of "Hell".

The "fire and brimstone" part comes from a set of passages in chapters 14 and 19-21 of the Literature/BookOfRevelation, in which [[{{Satan}} the devil]] and the ungodly are cast into a lake of fire and sulfur, which is generally considered to be the same as ''Gehenna'':

-->And another angel, a third, followed them, saying in a loud voice: "If anyone worships the wild beast and its image, and receives a [[MarkOfTheBeast mark]] on his forehead or upon his hand, he will also drink of the wine of the anger of God that is poured out undiluted into the cup of his wrath, and he shall be tormented with fire and sulfur in the sight of the holy angels and in the sight of the Lamb. And the smoke of their torment ascends forever and ever, and day and night they have no rest, those who worship the wild beast and its image, and whoever receives the mark of its name." (Revelation 14:9-11)\\
And the wild beast was caught, and along with it the false prophet that performed in front of it the signs with which he misled those who received the mark of the wild beast and those who render worship to its image. While still alive, they both were hurled into the fiery lake that burns with sulfur. (Revelation 19:20)\\
And the Devil who was misleading them was hurled into the lake of fire and sulfur, where both the wild beast and the false prophet already were; and they will be tormented day and night forever and ever. (Revelation 20:10)\\
And death and Hades were hurled into the lake of fire. This means the second death, the lake of fire. Furthermore, whoever was not found written in the book of life was hurled into the lake of fire. (Revelation 20:14, 15)\\
"But as for the cowards and those without faith and those who are disgusting in their filth and murderers and fornicators and those practicing spiritism and idolaters and all the liars, their portion will be in the lake that burns with fire and sulfur. This means the second death." (Revelation 21:8)

Note that the first and third passages DO mention damned humans. However, none of these passages say anything about being underground or demons doing the tormenting. In addition, Revelation is generally viewed to take place in the FUTURE, which some interpret meaning there isn't a "lake of fire" NOW, or at least nobody is in it yet.

As for the third and fourth passages, does the "tormented day and night forever and ever" really refer to eternal torture? While the Devil is a living entity, the wild beast and false prophet are not. They are symbols, and symbols cannot be tortured. Neither is the "lake of fire" an actual place. Additionally, death itself is obviously not a living entity, but a state of being. How can you torture death? To say that the verse means that the Devil will be literally tortured would also mean that symbols and death itself can also be tortured. The word translated as "torture" is [[ basanizo]]; while that translation is probably more common now, in ''ancient'' Greek, the ''primary'' translation referred to "testing/proving (on a touchstone)" or "examine closely", which would refer to testing and God's and Satan's rival claims to sovereignty as set out in Eden as told in Genesis chapter 3 against each other and finally resolving the issue, also setting a precedent on the issue and the prevention of another issue like it from ever arising. Thus the Satan will have been 'proved wrong' "day and night, forever and ever."

The more popular notion of FireAndBrimstoneHell where demons torment the damned appears to have originated with Dante's ''[[Literature/TheDivineComedy Inferno]]'', so this is OlderThanPrint... more or less. Most of the layers of Hell in ''Inferno'' were more like the IronicHell. [[{{Flanderization}} Only about one or two layers were]] TRULY Fire and Brimstone (In fact, the lowest level, reserved for traitors, was [[EvilIsDeathlyCold completely frozen over]]).

For the curious, brimstone is another word for sulfur and means "burning stone". It burns quite hot with a blue flame and is more or less unquenchable. It produces sulfur dioxide, which is quite noxious. All in all, it's an unpleasant sort of fire, one that historically was used to purify homes of bad air. Thus its purpose in hell is twofold: it cleans as it burns.

It should perhaps also be noted that FireAndBrimstoneHell is not a uniquely Christian concept. For example, there are a number of passages in The Qur'an that affirms its existence just as vigorously as (and [[{{Gorn}} much more graphically than]]) any of the Bible bits quoted in this article. A couple of examples:

-->Lo! Those who disbelieve Our revelations, We shall expose them to the Fire. As often as their skins are consumed We shall exchange them for fresh skins that they may taste the torment. (Surah 4:56, "The Women")\\
But as for those who disbelieve, garments of fire will be cut out for them; boiling fluid will be poured down on their heads, Whereby that which is in their bellies, and their skins too, will be melted; And for them are hooked rods of iron. Whenever, in their anguish, they would go forth from thence they are driven back therein and (it is said unto them): Taste the doom of burning. (Surah 22:19-22, "The Pilgrimage")

There is also the question of how "literal" Revelation is supposed to be interpreted anyway. Annihilationists believe that eternal punishment would instantly mean that GodIsEvil. The "lake of fire and sulfur" is not literal, but instead [[WhatDoYouMeanItsNotSymbolic figurative or symbolic]]. It represents [[KilledOffForReal eternal destruction]] and those sent there are [[DeaderThanDead completely obliterated]]. The only thing that lasts for eternity is the fire itself, and humans are not inherently immortal. After all, [[WordOfGod God Himself said to Adam and his sons that sinners will be returned to dust or destroyed, not given the Fruit of Life.]] They also argued that this was the stance of the original Jews who used the metaphor of the real-life garbage incinerator "Gehenna" to signify a place where sinners are annihilated forever. The concept of Eternal Punishment originated from Tartarus in Myth/ClassicalMythology, but it was only reserved for the most vile of Complete Monsters.
