Those "historians" may be looking for work soon in the exiting field of fast food:
Ignatius of Antioch
"Corrupters of families will not inherit the kingdom of God. And if they who do these things according to the flesh suffer death, how much more if a man corrupt by evil teaching the faith of God for the sake of which Jesus Christ was crucified? A man become so foul will depart into unquenchable fire: and so will anyone who listens to him" (Letter to the Ephesians 16:12 [A.D. 110]).
Second Clement
"If we do the will of Christ, we shall obtain rest; but if not, if we neglect his commandments, nothing will rescue us from eternal punishment" (Second Clement 5:5 [A.D. 150]).
"But when they see how those who have sinned and who have denied Jesus by their words or by their deeds are punished with terrible torture in unquenchable fire, the righteous, who have done good, and who have endured tortures and have hated the luxuries of life, will give glory to their God saying, There shall be hope for him that has served God with all his heart!" (ibid., 17:7).
Justin Martyr
"No more is it possible for the evildoer, the avaricious, and the treacherous to hide from God than it is for the virtuous. Every man will receive the eternal punishment or reward which his actions deserve. Indeed, if all men recognized this, no one would choose evil even for a short time, knowing that he would incur the eternal sentence of fire. On the contrary, he would take every means to control himself and to adorn himself in virtue, so that he might obtain the good gifts of God and escape the punishments" (First Apology 12 [A.D. 151]).
"We have been taught that only they may aim at immortality who have lived a holy and virtuous life near to God. We believe that they who live wickedly and do not repent will be punished in everlasting fire" (ibid., 21).
"[Jesus] shall come from the heavens in glory with his angelic host, when he shall raise the bodies of all the men who ever lived. Then he will clothe the worthy in immortality; but the wicked, clothed in eternal sensibility, he will commit to the eternal fire, along with the evil demons" (ibid., 52).
The Martyrdom of Polycarp
"Fixing their minds on the grace of Christ, [the martyrs] despised worldly tortures and purchased eternal life with but a single hour. To them, the fire of their cruel torturers was cold. They kept before their eyes their escape from the eternal and unquenchable fire" (Martyrdom of Polycarp 2:3 [A.D. 155]).
