Since everyone is talking about different views of Hell, here's one that hasn't been posted. I don't believe that Hell is a place, but I do believe in an eternal Hell. So, to put all my cards up front, I'll state bluntly that God is Hell.
Basically, God is fire. He is described repeatedly as such in the Scriptures. Likewise, there is no reason to be absolutely literal in the Scriptures. I don't believe Satan is a great dragon flying in the heavens, that death is a person, nor do I believe that Hell is a Lake of Fire or a burning garbage dump.
When God warned Adam, He told Him that the day he sinned, he would die. We all know that Adam sinned, and that he lived past that day physically. The spiritual death he had, though, forced him to be driven from the Garden (and yes, there's lots of symbolism and allegory here). Why is this? So that he wouldn't eat from the Tree of Life and live forever.
This Tree of Life is one and the same as the True Vine. Had they "eaten" this (it is metaphorical), they would have lived forever, but without any option for the salvific effects of Christ's sacrifice. Everyone is resurrected, and Adam was not ready for that resurrection.
Man could no longer live with God, and God's name may be taken to mean "The One Who Is." God is what He is. When Adam changed His relationship with God, He changed it from Paradise to something terrible. For that reason, Adam feared God. He hid from God.
In Christ, God became man, and now we may become participants in the divine nature (II Peter 1.4). This reality is taught blatantly in St. John. Christ said that He was the True Vine. The Church is built upon that. From Her, individuals branch out and become extensions of Him.
Christian itself means "little christ." In John 10.34-35, Christ uses the very fact that we are to be little christs to defend His claim to divinity. He said: "Is it not written in your law, `I said ``You are gods?''' If He called them gods, to whom the word of God came (and the Scripture cannot be broken), do you say of Him whom the Father sanctified and sent into the world, `You are blaspheming,' because I said, `I am the Son of God?'"
The Roman Catholic theologian Thomas Acquinas taught that we are as iron. In the outside world, we are dull. However, when we are placed in the fire (God), we shine like the heavens. Taken out of the fire, the iron again becomes dull. So it is with us. We can never be as God is, but God can live in us and restore us. If we are separated, we again become dull.
In this way, we can understand the Lake of Fire. The Greek word for Sulphur is "theion." It also translates as "divine" or "divinity." The "Lake of Fire and Brimstone" could well be the "Lake of Fire and Divinity." God is Hell. God is Heaven. The very word, "parousia," used in Jesus' "Second Coming" could also be "appearance," so it could be Jesus' "Second Appearance" or "Manifestation." God is revealed in His fullness to the universe, and there is nowhere to hide.
So, I don't believe Hell is a place. It is the presence of God. God is not a sadistic monster that likes to throw people into a dungeon with varying levels to be poked, prodded, burnt, and other such things. God just is Who He is. What we made ourselves, though, is another matter.
