“And the fact that it was not said of the seventh day equally with the other days, “And there was evening, and there was morning,” is a distinct indication of the consummation which is to take place in it before it is finished, as the fathers declare, especially St. Clement, and Irenaeus, and Justin the Martyr,”Justin Martyr
Other Fragments Ch. XV, Vol. 1

How have we been beguiled by the deceiver! how have we been joined to him! how have we been caught in his toils! how have we been taken in his abominable net! how have we heard the Scriptures, and understood them not! For truly those who are engrossed with the affairs of life, and with the lust of this world, will be easily brought over to the accuser then, and sealed by him. But many who are hearers of the divine Scriptures, and have them in their hand, and keep them in mind with understanding, will escape his imposture. For they will see clearly through his insidious appearance and his deceitful imposture, and will flee from his hands, and betake themselves to the mountains, and hide themselves in the caves of the earth; and they will seek after the Friend of man with tears and a contrite heart; and He will deliver them out of his toils, and with His right hand He will save those from his snares who in a worthy and righteous manner make their supplication to Him.Hippolytus
Appendix Pt. 1 Vol. 5

"Now it is sufficient very briefly to signify it: that virtue can neither be discerned, unless it has vices opposed to it; nor be perfect, unless it is exercised by adversity. For God designed that there should be this distinction between good and evil things, that we may know from that which is evil the quality of the good, and also the quality of the evil from the good; nor can the nature of the one be understood if the other is taken away. God therefore did not exclude evil, that the nature of virtue might be evident. For how could patient endurance retain its meaning and name if there were nothing which we were compelled to endure? How could faith devoted to its God deserve praise, unless there were some one who wished to turn us away from God? For on this account He permitted the unjust to be more powerful, that they might be able to compel to evil; and on this account to be more numerous, that virtue might be precious, because it is rare."Lactantius

"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 a 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:” (Joh_14:2)"Papias (Disciple of Apostle John)
Fragments of Papias Ch. V, Vol. 1

"Now we have understood that the expression used among these words, ‘According to the days of the tree [of life] shall be the days of my people; the works of their toil shall abound’ obscurely predicts a thousand years. For as Adam was told that in the day he ate of the tree he would die, we know that he did not complete a thousand years. We have perceived, moreover, that the expression, ‘The day of the Lord is as a thousand years,’ (Psa_90:4; 2Pe_3:8) is connected with this subject. And further, there was a certain man with us, whose name was John, one of the apostles of Christ, who prophesied, by a revelation that was made to him, that those who believed in our Christ would dwell a thousand years in Jerusalem; and that thereafter the general, and, in short, the eternal resurrection and judgment of all men would likewise take place. Just as our Lord also said, ‘They shall neither marry nor be given in marriage, but shall be equal to the angels, the children of the God of the resurrection.’ (Luk_20:35)"Justin Martyr
Dialogue with Trypho Vol. 1

"But God, as a most indulgent parent, when the last time approached, sent a messenger to bring back that old age, and justice which had been put to flight, that the human race might not be agitated by very great and perpetual errors. Therefore, the appearance of that golden time returned, and justice was restored to the earth, but was assigned to a few; and this justice is nothing else than the pious and religious worship of the one God."Lactantius

"The last enemy that shall be destroyed is death.” (1Co_15:25, 1Co_15:26) For in the times of the kingdom the just man who is on the earth shall forget to die."Papias (Disciple of Apostle John)
Fragments of Papias Ch. V, Vol. 1

so also, in [the times of] the end, the Word of the Father and the Spirit of God, having become united with the ancient substance of Adam’s formation, rendered man living and perfect, receptive of the perfect Father, in order that as in the natural [Adam] we all were dead, so in the spiritual we may all be made alive. (1Co_15:22) For never at any time did Adam escape the hands of God, to whom the Father speaking, said, “Let Us make man in our image, after our likeness.” And for this reason in the last times (fine), not by the will of the flesh, nor by the will of man, but by the good pleasure of the Father, (Joh_1:13) His hands formed a living man, in order that Adam might be created [again] after the image and likeness of God.Irenaeus
Against Heresies Book V Ch. I Vol.I

"Now the expression, “In the image of God created He him,” without any mention of the word “likeness,” conveys no other meaning than this, that man received the dignity of God’s image at his first creation; but that the perfection of his likeness has been reserved for the consummation, - namely, that he might acquire it for himself by the exercise of his own diligence in the imitation of God, the possibility of attaining to perfection being granted him at the beginning through the dignity of the divine image, and the perfect realization of the divine likeness being reached in the end by the fulfilment of the (necessary) works."Origen

"We take earnest heed in these last days; for the whole [past] time of your faith will profit you nothing, unless now in this wicked time we also withstand coming sources of danger, as become the sons of God. That the Black One may find no means of entrance, let us flee from every vanity, let us utterly hate the works of the way of wickedness. Do not, by retiring apart, live a solitary life, as if you were already [fully] justified; but coming together in one place, make common inquiry concerning what tends to your general welfare. For the Scripture said, “Woe to them who are wise to themselves, and prudent in their own sight!” (Isa_5:21)"Barnabas
Epistle Part 1 Ch. IV, Vol. 1

"So then, when the end has been restored to the beginning, and the termination of things compared with their commencement, that condition of things will be re-established in which rational nature was placed, when it had no need to eat of the tree of the knowledge of good and evil; so that when all feeling of wickedness has been removed, and the individual has been purified and cleansed, He who alone is the one good God becomes to him “all,” and that not in the case of a few individuals, or of a considerable number, but He Himself is “all in all.” And when death shall no longer anywhere exist, nor the sting of death, nor any evil at all, then verily God will be “all in all.”"Origen
De Principiis Bk. 3 Ch. VI, Vol. 4

When prophesying of these times, therefore, Isaiah says: “The wolf also shall feed with the lamb, and the leopard shall take his rest with the kid; the calf also, and the bull, and the lion shall eat together; and a little boy shall lead them. The ox and the bear shall feed together, and their young ones shall agree together; and the lion shall eat straw as well as the ox. And the infant boy shall thrust his hand into the asp’s den, into the nest also of the adder’s brood; and they shall do no harm, nor have power to hurt anything in my holy mountain.” And again he says, in recapitulation, “Wolves and lambs shall then browse together, and the lion shall eat straw like the ox, and the serpent earth as if it were bread; and they shall neither hurt nor annoy anything in my holy mountain, saith the Lord.” (Isa 40:6, etc.) I am quite aware that some persons endeavor to refer these words to the case of savage men, both of different nations and various habits, who come to believe, and when they have believed, act in harmony with the righteous. But although this is [true] now with regard to some men coming from various nations to the harmony of the faith, nevertheless in the resurrection of the just [the words shall also apply] to those animals mentioned. For God is non in all things. And it is right that when the creation is restored, all the animals should obey and be in subjection to man, and revert to the food originally given by God (for they had been originally subjected in obedience to Adam), that is, the productions of the earth. But some other occasion, and not the present, is [to be sought] for showing that the lion shall [then] feed on straw. And this indicates the large size and rich quality of the fruits. For if that animal, the lion, feeds upon straw [at that period], of what a quality must the wheat itself be whose straw shall serve as suitable food for lions?Irenaeus
