Hell in the New Testament
In the New Testament, the notion of hell is more clearly expressed, but still not in a systematic way. In many cases, "death" and "destruction" are the only mentioned penalties for rejecting God (e.g., Matthew 7:13, John 3:16, Acts 4:12, Romans 6:23, 2 Thessalonians 1:9, James 1:15). Also, as noted in the section above, the same terminology is often used in the New Testament that in the Jewish context may have suggested nothing more than physical death and destruction of the soul.
New Testament passages that have suggested eternal torment to Christians include the following:
"Anyone who says, 'You fool!' will be in danger of the fire of hell." (Matthew 5:22, quoting Jesus)
"And if your right hand causes you to sin, cut it off and throw it away. It is better for you to lose one part of your body than for your whole body to go into hell." (Matthew 5:29, quoting Jesus; see parallel passage in Mark 9:44, which adds, "where the fire never goes out.")
"Do not be afriad of those who kill the body but cannot kill the soul. Rather, be afraid of the One who can destroy both soul and body in hell." (Matthew 10:28, quoting Jesus)
"As the weeds are pulled up and burned in the fire, so it will be at the end of the age. The Son of Man will send out his angels, and they will weed out of his kingdom everything that causes sin and all who do evil. They will throw them into the fiery furnace, where there will be weeping and gnashing of teeth." (Matthew 13:40-42, quoting Jesus)
"Throw that worthless servant outside, into the darkness, where there will be weeping and gnashing of teeth." (Parable of the Talents, Matthew 25:30)
"Then he [the King] will say to those on his left, 'Depart from me, you who are cursed, into the eternal fire prepared for the devil and his angels." (Parable of the Sheep and the Goats, Matthew 25:41)
"The tongue also is a fire, a world of evil among the parts of the body. It corrupts the whole person, sets the whole course of his life on fire, and is itself set on fire by hell." (James 3:6)
"The sea gave up the dead that were in it, and death and Hades gave up the dead that were in them, and each person was judged according to what he had done. Then death and Hades were thrown into the lake of fire. The lake of fire is the second death. If anyone's name was not found written in the book of life, he was thrown into the lake of fire." (Revelation 20:13-15)
"The cowardly, the unbelieving, the vile...the idolaters and all liars - their place will be in the fiery lake of burning sulpher. This is the second death." (Revelation 21:8)
The Doctrine of Hell in the Church Fathers
In the church fathers (post-New-Testament Christian leaders and theologians), the doctrine of hell quickly becomes more well-defined as a place of eternal torment, which is generally seen as physical in nature: {5}
"The way of darkness is crooked, and it is full of cursing. It is the way of eternal death with punishment." (Pseudo-Barnabas, c. 70-130 AD)
"You should fear what is truly death, which is reserved for those who will be condemned to the eternal fire. It will afflict those who are committed to it even to the end." (Letter to Diognetus, c. 125-200)
"[The martyrs] despised all the torments of this world, redeeming themselves from eternal punishment by the suffering of a single hour.... For they kept before their view escape from that fire which is eternal and will never be quenched." (Martyrdom of Polycarp, c. 135)
"Sinners will be consumed because they sinned and did not repent." (Shepherd of Hermas, c. 150)
"Those who have not known God and do evil are condemned to death. However, those who have known God and have seen his mighty works, but still continue in evil, will be chastised doubly, and will die forever." (Shepherd of Hermas, c. 150)
"We believe...that every man will suffer punishment in eternal fire according to the merits of his deed. ... Sensation remains to all who have ever lived, and eternal punishment is laid up." (Justin Martyr, c. 160)
"Hell [Gehenna] is a place where those who have lived wickedly are to be punished." (Justin Martyr, c. 160)
"Some are sent to be punished unceasingly into judgment and condemnation of fire." (Justin Martyr, c. 160)
"We who are now easily susceptible to death, will afterwards receive immortality with either enjoyment or with pain." (Tatian, c. 160)
"We are persuaded that when we are removed from the present life we will live another life, better than the present one...or, if they fall with the rest, they will endure a worse life, one in fire. For God has not made us as sheep or beasts of burden, who are mere by-products. For animals perish and are annihilated. On these grounds, it is not likely that we would wish to do evil." (Athenagoras, c. 175)
"To the unbelieving and despisers...there will be anger and wrath, tribulation and anguish. At the end, everlasting fire will possess such men." (Theophilus, c. 180)
"Eternal fire is prepared for sinners. The Lord has plainly declared this and the rest of the Scriptures demonstrate it." (Irenaeus, c. 180)
"All souls are immortal, even those of the wicked. Yet, it would be better for them if they were not deathless. For they are punished with the endless vengeance of quenchless fire. Since they do not die, it is impossible for them to have an end put to their misery." (Clement of Alexandria, c. 195; from a post-Nicene manuscript fragment)
"We [Christians] alone make a real effort to attain a blameless life. We do this under the influence of... the magnitude of the threatened torment. For it is not merely long-enduring; rather, it is everlasting." (Tertullian, c. 197)
"Gehenna... is a reservoir of secret fire under the earth for purposes of punishment." (Tertullian, c. 197)
"There is neither limit nor termination of these torments. There, the intelligent fire burns the limbs and restores them. It feeds on them and nourishes them. ... However, no one except a profane man hesitates to believe that those who do not know God are deservedly tormented." (Mark Minucius Felix, c. 200)
However, some early church fathers, such as Origen of Alexandria and Gregory of Nyssa, questioned the eternality of hell and the literal interpretation of it as a fiery place. {6}
Modern Christian Views of Hell
Modern Christian views of hell tend to emphasize its spiritual aspects over the notion of physical suffering or material fire. Hell is seen as a logical extension of the free will of mankind to reject God's gracious advances, even for eternity, and its punishment as a realization of one's mistake and the great remorse that would follow. Many modern Christians also question hell's eternality in favor of some form of universalism (all are saved in the end) or annihilationism (wicked souls are destroyed).
Following is a sampling of the positions of various Christian denominations on the issue of hell.
It is impossible to describe the glory and splendor of heaven and the terror and torment of hell. Whether taken literally or figuratively, the meaning is the same: Hell is a place where one will experience total separation from God; heaven enjoys the total presence of God. Knowing that this is the horrible end awaiting the wicked, the Assemblies of God is strongly motivated to win the lost before it is too late. (Assemblies of God)
To die in mortal sin without repenting and accepting God's merciful love means remaining separated from him for ever by our own free choice. This state of definitive self- exclusion from communion with God and the blessed is called "hell." (Catechism of the Catholic Church)
The statement of Christ in Matthew 25, and elsewhere, are taken at face value. It is believed that after death each man must come before God in judgment and that he will be judged according to the deeds done while he lived (Hebrews 9:27). After judgment is pronounced he will spend eternity either in heaven or hell. (Churches of Christ)
We believe that glorious and everlasting life is assured to all who savingly believe in, and obediently follow, Jesus Christ our Lord; and that the finally impenitent shall suffer eternally in hell. (Church of the Nazarene)
This hope for the final salvation of humanity and the eternal universal restitution of all things in heaven and on earth ... is drawn from the unlimited promise of the Gospel and the magnitude of God's grace made known to the world through Christ. (Evangelical Lutheran Church of America)
We believe in the bodily resurrection of the dead; of the believer to everlasting blessedness and joy with the Lord; of the unbeliever to judgment and everlasting conscious punishment. (Evangelical Free Church of America)
The moral progress of the soul, either for better or for worse, ends at the very moment of the separation of the body and soul; at that very moment the definite destiny of the soul in the everlasting life is decided. ... The Orthodox Church believes that at this moment the soul of the dead person begins to enjoy ... the life in Paradise or to undergo the life in Hell. There is no way of repentance, no way of escape, no reincarnation and no help from the outside world. (Greek Orthodox Archdiocese of America)
