Liberal Christian Beliefs
Liberal Christians recognize that the writers of the Bible held a variety of beliefs concerning Heaven and Hell. The earliest books of the Bible described an underground cavern where all people, good and bad, spent eternity after death. The later books described Hell as either a place of annihilation or of eternal punishment. Generally speaking, this system of beliefs looks upon Hell as a concept, not as a place of punishment. The idea that a person would suffer eternal punishment for a single oversight, error or sin during life is seen as unjust. Punishment of an individual because she/he had never heard the Gospel is also viewed as irrational and unjust. They feel that a loving God would be incapable of creating such a place.
Conservative
Protestant Beliefs
Generally speaking, conservative Protestants believe that everyone has
the gift of eternal life. The body dies, but the soul lives forever. The
big question is where each person will spend eternity. Heaven is a
glorious location where there is an absence of pain, disease, sex,
depression, etc. and where people live in new, spiritual bodies, in the
presence of Jesus Christ. Hell is a location where its inmates will be
punished without any hope of relief, for eternity. The level of
punishment will be the same for everyone. The Bible talks about fire and
(presumably flesh eating) worms.
The second major belief is that most humans will be sent to Hell after they die. Only those few who have been "saved" will go to heaven. Salvation requires repentance of sins and trusting Jesus as one's Lord and Savior. People who have been saved and make it to heaven will not all be treated equally. Believers who have done many good deeds will be rewarded more in heaven; believers who have led an evil life will be rewarded less.
Roman Catholic
Hell is a location where its inmates will be punished without any hope of
relief, for eternity. Among those punished will be Satan, the angels that
supported him, and persons who have died without having repented their
sins. Sincere confession of a mortal sin to an authorized priest and
making restitution if required, leads to absolution of the sin, and the
avoidance of Hell. The level of punishment will be meted out in
accordance with the seriousness of the individual's sin.
In Hell, punishment will be in the form of isolation from God, and some supernatural form of fire which causes endless pain but does not consume the body. The Church teaches that "the souls of those who have died in the state of grace suffer for a time a purging that prepares them to enter heaven." They spend time in Purgatory until fully cleansed of imperfections, venial (less serious) sins etc. Purgatory will be terminated at the time of the general judgement. The intensity and duration of the punishment can be reduced by friends and family, if they offer Masses, prayers "and other acts of piety and devotion." For babies who died unbaptized, they entered heaven after staying in limbo for a while.
Jehovah's Witnesses
Members of The Watchtower Bible & Tract Society (WTS) believe that Hell
does not exist. They interpret Hell symbolically as the "common grave of
mankind." Most people simply cease to exist at death; they are
annihilated. The Heavenly Kingdom was established in 1914 CE. A "little
flock" or "Anointed Class" of about 135,400 people are believed by this
group to currently inhabit Heaven. Another 8,600 are still alive and will
also spend eternity with God at a later date.
The battle of Armageddon will start soon. Jesus, under Jehovah's divine rage, will execute vengeance upon the rest of Christendom and followers of "Babylon the Great" (other religions). After the world is purified, a theocracy "God's Kingdom" will be established on earth for 1000 years. Those who survive Armageddon, the "other sheep," will live in peace in the newly created utopia. They will be joined by the worthy dead who have been resurrected. After 1000 years of God's Kingdom, Satan, his demon forces and all those rebellious ones who turn against God will be finally destroyed. In order to be saved, a person must accept the doctrines formulated by the WTS Governing Body, be baptized as a Jehovah's Witness, and follow the program of works as laid out by the Governing Body.

Mormons
Members of the Church of Jesus Christ of Latter-day Saints believe that
not one, but three heavens exist. The highest levels of the Celestial
Kingdom are reserved for Mormon couples who have been married in a Mormon
temple and thus have had their marriage sealed for eternity. The couples
can eventually become a God and Goddess; the husband will then be in
control of an entire universe. The Terrestrial Kingdom, is the
destination for most individuals. The Terrestrial Kingdom is for "liars,
and sorcerers, and adulterers, and whoremongers"
Hell exists, but very few people will stay there forever. Most will eventually "pass into the terrestrial kingdom; the balance, cursed as 'sons of perdition', will be consigned to partake of endless wo [sic] with the devil and his [fallen] angels." Sons of perdition have been defined as once devout Mormons who have become apostates and have left the church. Others define them as persons who have knowingly committed one of the most serious sins and have not repented and sought God's forgiveness. Among these almost unforgivable sins are murder and pre-marital sex. Learn more about Mormons >>
Seventh Day
Adventists
The Seventy-Day Adventists believe in the traditional concept of Heaven
and Hell. However, they do not believe that Hell is a place of eternal
punishment "with sinners screaming in agony without end." They view Hell
as a place where the unsaved will be burned up, reduced to ashes, and
annihilated. They cite Biblical verses to show that the "'everlasting' in
'everlasting hell' means 'as long as there is something to burn in hell.'
Our God is a loving God and to portray sinners as screaming in agony
forever and ever does not portray God in such light."
