Vanderhovan: Cold Steel, What is the position of the LDS church on hell and torment?
It’s complicated, and it’s based on modern revelation rather than just what’s in the Bible (which isn’t much).
The term “Eternal” is esoteric. Just as Eternal Life doesn’t merely mean living forever, Eternal Torment doesn’t mean being tormented forever. Rather, the term “Eternal” is a term that refers to that which is meted out by God. In the Book of Mormon, a man by the name of Alma who, with his friends, were miscreants in their youth. Then they were confronted by an angel and severely rebuked after which they fell to the earth and remained as dead for three days.
Afterwards, Alma wrote that he “was racked with eternal torment, for my soul was harrowed up to the greatest degree and racked with all my sins.” He said he suffered “eternal torment” and yet it lasted but mere days (though I’m sure it seemed to last longer). He also described his experience I did remember all my sins and iniquities, for which I was tormented with the pains of hell; yea, I saw that I had rebelled against my God, and that I had not kept his holy commandments. Yea, and I had...led [many of God’s children] away unto destruction; yea, and in fine so great had been my iniquities, that the very thought of coming into the presence of my God did rack my soul with inexpressible horror.” (Alma 36)
In Mormon theology, those who have sinned against the Holy Spirit — that is, those who have received a sure knowledge of the power of God and then denied it — are called “sons of perdition.” They are those who are resurrected with no glory and cast into outer darkness with Satan and his angels.
Sidney Rigdon was one of the co-founders of the churches of Christ. But in the late 1820s he broke away from Alexander Campbell over the issue that they lacked the authority from God to baptize, ordain, confer the Holy Spirit by the laying on of hands. An astounding speaker and preacher, he met Joseph Smith and became convinced that the LDS faith had that authority. He also believed that Smith received the revelations and visions he said he had.
In 1832, he had an experience confirming those beliefs. Both he and Smith received a joint revelation known from that day forth as “The Vision.” Regarding the fate of the wicked, the two prophets were told that the atonement of Christ guaranteed each of God’s children an inheritance, and the scriptures state that the time would come when every knee shall bend and every tongue confess Christ. And though people will inherit varying degrees of glory, many will have to pass through hell to fully comprehend the pain and suffering they’ve caused others. The revelation states in part:

These are they which have willfully placed themselves beyond God’s power, and according to the revelation, no one knows their ultimate fate save those who are partakers of it:

The nature of this revelation caused many of the early latter-day saints problems because it went against everything they had been taught. In fact, it went against everything Rigdon and Smith had been taught. There were others present when this vision was given and though some could see glory, or light, emanating from Rigdon’s and Smith’s faces, only Rigdon and Smith actually saw the vision. One would say, “What do I see?” and then describe what he was seeing, and the other would say, “I see the same.” Then he would say what he saw, and it went back and forth and written in real time by a scribe. One LDS authority years later said: “What, then, is ‘the second death?’ ... It is eternal banishment from His presence. He is the source of light and truth and power and glory and happiness and joy and dominion and increase forever, of which they will all be deprived. Being shut right out from the light, these shall go away into outer darkness where no ray of light comes, spiritual or physical-no ray of light from sun or moon or twinkling star or even a comet; to be in outer darkness, and no wonder there is ‘weeping and wailing and gnashing of teeth,’ to use the scriptural expression.”
Some of our early authorities speculated that Satan, his angels and the sons of perdition would be reduced to their native elements and they used potter’s clay and defective vessels as examples. When pottery is defective, it will be broken down and returned to the clay, never to become that vessel again. Some LDS church members speculate that such spirits will be consigned to black holes, which seem to fit the term “outer darkness.” Since no one knows what happens once one passes through an event horizon — whether there are time dilations or whether it simply rips all matter to pieces, who knows. A black hole seems to the only thing in the universe completely devoid of light. But be that as it is, it, too, is merely speculation. Many think that spirits are not matter, but according to our scriptures, they are; just a more refined matter.
