No it is not. It is brainwashing when you can't consider anything other than what someone else told you. The early Christian writings support an eternal punishment. They don't say anything about unjust torture that continues long after the suffered more than enough for their sins.
First you say "eternal punishment" then you say "unjust torture." If God imposes it then it is neither unjust nor torture. Here are some quotes from the early church on eternal punishment.
“The Epistle of Barnabas” (70-130AD)
The way of darkness is crooked, and it is full of cursing. It is the way of eternal death with punishment.
Ignatius of Antioch (110AD)
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 reaching 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 16:1-2)
From Clement of Rome (150AD)
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)
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!’ (“Second Clement” 17:7)
From “The Martyrdom of Polycarp” (155AD)
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)
From Tatian (160AD)
We who are now easily susceptible to death, will afterwards receive immortality with either enjoyment or with pain.
From Athenagoras of Athens (175AD)
Athenagoras was a philosopher and citizen of Athens who became a Christian (possibly from Platonism) and wrote two important apologetic works; “Apology” or “Embassy for the Christians”, and a “Treatise on the Resurrection”:
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. (“Apology”)
From Theophilus of Antioch (181AD)
Give studious attention to the prophetic writings [the Bible] and they will lead you on a clearer path to escape the eternal punishments and to obtain the eternal good things of God. . . . [God] will examine everything and will judge justly, granting recompense to each according to merit. To those who seek immortality by the patient exercise of good works, he will give everlasting life, joy, peace, rest, and all good things. . . . For the unbelievers and for the contemptuous, and for those who do not submit to the truth but assent to iniquity, when they have been involved in adulteries, and fornications, and homosexualities, and avarice, and in lawless idolatries, there will be wrath and indignation, tribulation and anguish; and in the end, such men as these will be detained in everlasting fire (“To Autolycus” 1:14)
From Irenaeus (189AD)
…Christ Jesus, our Lord, and God, and Saviour, and King, according to the will of the invisible Father, ‘every knee should bow, of things in heaven,, and things in earth, and things under the earth, and that every tongue should confess’ to Him, and that He should execute just judgment towards all; that He may send ‘spiritual wickednesses,’ and the angels who transgressed and became apostates, together with the ungodly, and unrighteous, and wicked, and profane among men, into everlasting fire; but may, in the exercise of His grace, confer immortality on the righteous, and holy, and those who have kept His commandments, and have persevered in His love, some from the beginning of their Christian course, and others from the date of their repentance, and may surround them with everlasting glory. (“Against Heresies” 1:10:10)
The penalty increases for those who do not believe the Word of God and despise his coming. . . . [I]t is not merely temporal, but eternal. To whomsoever the Lord shall say, ‘Depart from me, accursed ones, into the everlasting fire,’ they will be damned forever (“Against Heresies” 4:28:2)
From Clement of Alexandria (195AD)
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. (from a post-Nicene manuscript fragment)
From Tertullian (197AD)
These have further set before us the proofs He has given of His majesty in judgments by floods and fires, the rules appointed by Him for securing His favor, as well as the retribution in store for the ignoring, forsaking and keeping them, as being about at the end of all to adjudge His worshippers to everlasting life, and the wicked to the doom of fire at once without ending and without break, raising up again all the dead from the beginning, reforming and renewing them with the object of awarding either recompense. (“Apology” 18:3)
Then will the entire race of men be restored to receive its just deserts according to what it has merited in this period of good and evil, and thereafter to have these paid out in an immeasurable and unending eternity. Then there will be neither death again nor resurrection again, but we shall be always the same as we are now, without changing. The worshipers of God shall always be with God, clothed in the proper substance of eternity. But the godless and those who have not turned wholly to God will be punished in fire equally unending, and they shall have from the very nature of this fire, divine as it were, a supply of incorruptibility (“Apology” 44:12–13)
Therefore after this there is neither death nor repeated resurrections, but we shall be the same that we are now, and still unchanged–the servants of God, ever with God, clothed upon with the proper substance of eternity; but the profane, and all who are not true worshippers of God, in like manner shall be consigned to the punishment of everlasting fire–that fire which, from its very nature indeed, directly ministers to their incorruptibility. (“Apology” 48:12)
If, therefore, any one shall violently suppose that the destruction of the soul and the flesh in hell amounts to a final annihilation of the two substances, and not to their penal treatment (as if they were to be consumed, not punished), let him recollect that the fire of hell is eternal — expressly announced as an everlasting penalty; and let him admit that it is from this circumstance that this never-ending "killing" is more formidable than a merely human murder, which is only temporal. — On the Resurrection of the Flesh Chapter 35
From Hippolytus of Rome (212AD)
Standing before [Christ’s] judgment, all of them, men, angels, and demons, crying out in one voice, shall say: ‘Just is your judgment!’ And the righteousness of that cry will be apparent in the recompense made to each. To those who have done well, everlasting enjoyment shall be given; while to the lovers of evil shall be given eternal punishment. The unquenchable and unending fire awaits these latter, and a certain fiery worm which does not die and which does not waste the body but continually bursts forth from the body with unceasing pain. No sleep will give them rest; no night will soothe them; no death will deliver them from punishment; no appeal of interceding friends will profit them (“Against the Greeks 3”)
From Felix Minucius (226AD)
I am not ignorant of the fact that many, in the consciousness of what they deserve, would rather hope than actually believe that there is nothing for them after death. They would prefer to be annihilated rather than be restored for punishment… Nor is there either measure nor end to these torments. That clever fire burns the limbs and restores them, wears them away and yet sustains them, just as fiery thunderbolts strike bodies but do not consume them (“Octavius” 34:12–5:3)
From Cyprian of Carthage (252 AD)
An ever-burning Gehenna and the punishment of being devoured by living flames will consume the condemned; nor will there be any way in which the tormented can ever have respite or be at an end. Souls along with their bodies will be preserved for suffering in unlimited agonies. . . . The grief at punishment will then be without the fruit of repentance; weeping will be useless, and prayer ineffectual. Too late will they believe in eternal punishment, who would not believe in eternal life (“To Demetrian” 24)
Oh,what and how great will that day be at its coming, beloved brethren, when the Lord shall begin to count up His people, and to recognize the deservings of each one by the inspection of His divine knowledge, to send the guilty to Gehenna, and to set on fire our persecutors with the perpetual burning of a penal fire, but to pay to us the reward of our faith and devotion! (“To Thibaris” 55:10)
From Lactantius (307AD)
But, however, the sacred writings inform us in what manner the wicked are to undergo punishment. For because they have committed sins in their bodies, they will again be clothed with flesh, that they may make atonement in their bodies; and yet it will not be that flesh with which God clothed man, like this our earthly body, but indestructible, and abiding forever, that it may be able to hold out against tortures and everlasting fire…The same divine fire, therefore, with one and the same force and power, will both burn the wicked and will form them again, and will replace as much as it shall consume of their bodies, and will supply itself with eternal nourishment …Then they whose piety shall have been approved of will receive the reward of immortality; but they whose sins and crimes shall have been brought to light will not rise again, but will be hidden in the same darkness with the wicked, being destined to certain punishment. (“Divine Institutes” 7:21)
From Cyril of Jerusalem (350AD)
We shall be raised therefore, all with our bodies eternal, but not all with bodies alike: for if a man is righteous, he will receive a heavenly body, that he may be able worthily to hold converse with angels; but if a man is a sinner, he shall receive an eternal body, fitted to endure the penalties of sins, that he may burn eternally in fire, nor ever be consumed… (“Catechetical Lectures” 18:19)
The real and true life then is the Father, who through the Son in the Holy Spirit pours forth as from a fountain His heavenly gifts to all; and through His love to man, the blessings of the life eternal are promised without fail to us men also. We must not disbelieve the possibility of this, but having an eye not to our own weakness but to His power, we must believe; for with God all things are possible. And that this is possible, and that we may look for eternal life, Daniel declares, And of the many righteous shall they shine as the stars forever and ever. And Paul says, And so shall we be ever with the Lord: for the being forever with the lord implies the life eternal. But most plainly of all the Savior Himself says in the Gospel, And these shall go away into eternal punishment, but the righteous into life eternal. (“Catechetical Lectures” 18:28)
