Marvel not at this: for the hour is coming, in the which all that are in the graves shall hear his voice, and shall come forth; they that have done good, unto the resurrection of life; and they that have done evil, unto the resurrection of damnation. John 5:28-29

And, behold, I come quickly; and my reward is with me, to give every man according as his work shall be. Revelation 22:12

But I will forewarn ye whom you shall fear: Fear him, which after he hath killed hath power to cast into hell; yea, I say unto you, fear him. Luke 12:5

[As the elders who saw John the disciple of the Lord remembered that they had heard from him how the Lord taught in regard to those times, and said]: The days will come in which vines shall grow, having each ten thousand branches, and in each branch ten thousand twigs, and in each true twig ten thousand shoots, and in every one of the shoots ten thousand clusters, and on every one of the clusters ten thousand grapes, and every grape when pressed will give five-and-twenty metretes of wine. And when any one of the saints shall lay hold of a cluster, another shall cry out, ‘I am a better cluster, take me; bless the Lord through me.’ In like manner, [He said] that a grain of wheat would produce ten thousand ears, and that every ear would have ten thousand grains, and every grain would yield ten pounds of clear, pure, fine flour; and that apples, and seeds, and grass would produce in similar proportions; and that all animals, feeding then only on the productions of the earth, would become peaceable and harmonious, and be in perfect subjection to man. Papias (A.D. 60-130) fragment IV

As the presbyters say, then those who are deemed worthy of an abode in heaven shall go there, others shall enjoy the delights of Paradise, and others shall possess the splendor of the city; for everywhere the Savior will be seen, according as they shall be worthy who see Him. But that there is this distinction between the habitation of those who produce an hundredfold, and that of those who produce sixty-fold, and that of those who produce thirty-fold; for the first will be taken up into the heavens, the second class will dwell in Paradise, and the last will inhabit the city; and that on this account the Lord said, “In my Father’s house are many mansions:” for all things belong to God, who supplies all with a suitable dwelling-place, even as His word says, that a share is given to all by the Father, according as each one is or shall be worthy. And this is the couch in which they shall recline who feast, being invited to the wedding. The presbyters, the disciples of the apostles, say that this is the gradation and arrangement of those who are saved, and that they advance through steps of this nature; and that, moreover, they ascend through the Spirit to the Son, and through the Son to the Father; and that in due time the Son will yield up His work to the Father…Papias (A.D. 60-130) fragment V

And Their worm shall not die, and their fire shall not be quenched, and they shall be for a spectacle unto all flesh. He speaks of that day of judgment, when men shall see those among us that lived ungodly lives and dealt falsely with the commandments of Jesus Christ. But the righteous, having done good and endured torments and hated the pleasures of the soul, when they shall behold them that have done amiss and denied Jesus by their words or by their deeds, how that they are punished with grievous torments in unquenchable fire, shall give glory to God, saying, There will be hope for him that has served God with his whole heart. Second Clement (A.D. 100) ch.17

No righteous man has reaped fruit quickly, but waits for it. For if God had paid the recompense of the righteous speedily, then straightway we should have been training ourselves in merchandise, and not in godliness; for we should seem to be righteous, though we were pursuing not that which is godly, but that which is gainful. And for this cause Divine judgment overtakes a spirit that is not just, and loads it with chains. Second Clement (A.D. 100) ch.20

And, looking to the grace of Christ, they despised all the torments of this world, redeeming themselves from eternal punishment by [the suffering of] a single hour. For this reason the fire of their savage executioners appeared cool to them. For they kept before their view escape from that fire which is eternal and never shall be quenched, and looked forward with the eyes of their heart to those good things which are laid up for such as endure; things “which ear has not heard, nor eye seen, neither have entered into the heart of man,” but were revealed by the Lord to them. Martyrdom of Polycarp (A.D. 156) ch. 2

But again the proconsul said to him, “I will cause you to be consumed by fire, seeing you despise the wild beasts, if you will not repent.” But Polycarp said, “You threaten me with fire which burns for an hour, and after a little is extinguished, but are ignorant of the fire of the coming judgment and of eternal punishment, reserved for the ungodly. But why do you wait? Bring forth what you will.” Martyrdom of Polycarp (A.D. 156) ch.11

You shall behold that God lives in heaven; then shall you begin to declare the mysteries of God; then shall you both love and admire those that are punished because they will not deny God; then shall you condemn the deceit and error of the world; when you shall perceive the true life which is in heaven, when you shall despise the apparent death which is here on earth, when you shall fear the real death, which is reserved for those that shall be condemned to the eternal fire that shall punish those delivered over to it unto the end. Then shall you admire those who endure for righteousness’ sake the fire that is for a season, and shall count them blessed when you perceive that fire … Letter to Diognetus (A.D. 125-200) ch.10

“He that knows not God,” said he, “and commits wickedness, has a certain punishment for his wickedness; but he that knows God fully ought not any longer to commit wickedness, but to do good. If then he that ought to do good commits wickedness, does he not seem to do greater wickedness than the man that knows not God? Therefore they that have not known God, and commit wickedness, are condemned to death; but they that have known God and seen His mighty works, and yet commit wickedness, shall receive a double punishment, and shall die eternally. In this way therefore shall the Church of God be purified. Hermas (A.D. 150) Ante-Nicene Fathers vol.2 pg.50

Each man goes to everlasting punishment or salvation according to the value of his actions. For if all men knew this, no one would choose wickedness even for a little, knowing that he goes to the everlasting punishment of fire; but would by all means restrain himself, and adorn himself with virtue, that he might obtain the good gifts of God, and escape the punishments. Justin Martyr (A.D. 160) Ante-Nicene Fathers vol.1 pg.166

For reflect upon the end of each of the preceding kings, how they died the death common to all, which, if it issued in insensibility, would be a godsend to all the wicked. But since sensation remains to all who have ever lived, and eternal punishment is laid up (i.e., for the wicked), see that you neglect not to be convinced, and to hold as your belief, that these things are true. For let even necromancy, and the divinations you practice by immaculate children, and the evoking of departed human souls, and those who are called among the magi, Dream-senders and Assistant-spirits (Familiars), and all that is done by those who are skilled in such matters – let these persuade you that even after death souls are in a state of sensation. Justin Martyr (A.D. 160) Ante-Nicene Fathers vol.1 pg.169

And we have learned that those only are deified who have lived near to God in holiness and virtue; and we believe that those who live wickedly and do not repent are punished in everlasting fire.Justin Martyr (A.D. 160) Ante-Nicene Fathers vol.1 pg.170

We have learned from the prophets, and we hold it to be true, that punishments, and chastisements, and good rewards, are rendered according to the merit of each man’s actions. Justin Martyr (A.D. 160) Ante-Nicene Fathers vol.1 pg.177

For as, in the New Testament, that faith of men [to be placed] in God has been increased, receiving in addition [to what was already revealed] the Son of God, that man too might be a partaker of God. Thus also the punishment of those who do not believe the Word of God, and despise His advent, and are turned away backwards, is increased; being not merely temporal, but rendered also eternal. For to whomsoever the Lord shall say, “Depart from me, you cursed, into everlasting fire,” these shall be damned for ever; and to whomsoever He shall say, “Come, you blessed of my Father, inherit the kingdom prepared for you for eternity,” these do receive the kingdom for ever, and make constant advance in it.Irenaeus (A.D. 180) Ante-Nicene Fathers vol.1 pg.501

Conformably, therefore, there are various abodes, according to the worth of those who have believed. To the point Solomon says, “For there shall be given to him the choice grace of faith, and a more pleasant lot in the temple of the Lord.” For the comparative shows that there are lower parts in the temple of God, which is the whole Church. And the superlative remains to be conceived, where the Lord is. These chosen abodes, which are three, are indicated by the numbers in the Gospel — the thirty, the sixty, the hundred. And the perfect inheritance belongs to those who attain to “a perfect man,” according to the image of the Lord… But “it is enough for the disciple to become as the Master,” said the Master. To the likeness of God, then, he that is introduced into adoption and the friendship of God. Clement of Alexandria (A.D. 195) Ante-Nicene Fathers vol.2 pg.506

All souls are immortal, even those of the wicked, for whom it were better that they were not deathless. For, punished with the endless vengeance of quenchless fire, and not dying, it is impossible for them to have a period put to their misery. Clement of Alexandria (A.D. 195) Ante-Nicene Fathers vol.2 pg.581

Accordingly, we get ourselves laughed at for proclaiming that God will one day judge the world. For, like us, the poets and philosophers set up a judgment-seat in the realms below. And if we threaten Gehenna, which is a reservoir of secret fire under the earth for purposes of punishment, we have in the same way derision heaped on us. Tertullian (A.D. 198) Ante-Nicene Fathers vol.3 pg.52
