"Sometimes the complaint is heard that no one preaches about hell any longer. The subject of hell, if not attractive, is at least fascinating, as any reader of Dante’s Inferno or Milton’s Paradise Lost can testify. Equally fascinating, and decidedly more pressing, is the question of how many of us may be expected to go there when we die.
As we know from the Gospels, Jesus spoke many times about hell. Throughout his preaching, he holds forth two and only two final possibilities for human existence: the one being everlasting happiness in the presence of God, the other everlasting torment in the absence of God. He describes the fate of the damned under a great variety of metaphors: everlasting fire, outer darkness, tormenting thirst, a gnawing worm, and weeping and gnashing of teeth."
"...The New Testament does not tell us in so many words that any particular person is in hell. But several statements about Judas can hardly be interpreted otherwise. Jesus says that he has kept all those whom the Father has given him except the son of perdition (John 17:12). At another point Jesus calls Judas a devil (John 6:70), and yet again says of him: “It would be better for that man if he had never been born” (Matthew 26:24; Mark 14:21). If Judas were among the saved, these statements could hardly be true. Many saints and doctors of the Church, including St. Augustine and St. Thomas Aquinas, have taken it as a revealed truth that Judas was reprobated. Some of the Fathers place the name of Nero in the same select company, but they do not give long lists of names, as Dante would do."
