Epistle of Barnabus
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 becomes the sons of God. That the Black One may find no means of entrance.
The Sabbath is mentioned at the beginning of the creation [thus]: “And God made in six days the works of His hands, and made an end on the seventh day, and rested on it, and sanctified it.” Attend, my children, to the meaning of this expression, “He finished in six days.” This implies that the Lord will finish all things in six thousand years, for a day is with Him a thousand years. And He Himself testifies, saying, “Behold, to-day will be as a thousand years.” Therefore, my children, in six days, that is, in six thousand years, all things will be finished. “And He rested on the seventh day.” This means: when His Son, coming [again], shall destroy the time of the wicked man, and judge the ungodly, and change the-sun, and the moon, and the stars, then shall He truly rest on the seventh day. – ibid
Watch for your life’s sake. Let not your lamps be quenched, nor your loins unloosed; but be ready, for you know not the hour in which our Lord will come. But come together often, seeking the things which are befitting to your souls: for the whole time of your faith will not profit you, if you are not made perfect in the last time. For in the last days false prophets and corrupters shall be multiplied, and the sheep shall be turned into wolves, and love shall be turned into hate; for when lawlessness increases, they shall hate and persecute and betray one another, and then shall appear the world-deceiver as Son of God, and shall do signs and wonders, and the earth shall be delivered into his hands, and he shall do iniquitous things which have never yet come to pass since the beginning. Then shall the creation of men come into the fire of trial, and many shall be made to stumble and shall perish; but those who endure in their faith shall be saved from under the curse itself. And then shall appear the signs of the truth: first, the sign of an outspreading in heaven, then the sign of the sound of the trumpet. And third, the resurrection of the dead – yet not of all, but as it is said: “The Lord shall come and all His saints with Him.” Then shall the world see the Lord coming upon the clouds of heaven.
These are the last times. Henceforth let us have reverence; let us fear the long-suffering of God, lest it turn into a judgment against us. For either let us fear the wrath which is to come or let us love the grace which now is – the one or the other; provided only that we be found in Christ Jesus unto true life.
Shepherd of Hermas
The fire and blood color shows that this world must perish by blood and fire; and the golden part are you that has escaped from this world. For as the gold is tested by the fire and is made useful, so you also [that dwell in it] are being tested in yourselves. You then that abide and pass through the fire will be purified by it.
And therefore, when in the end the Church shall be suddenly caught up from this, it is said, “There shall be tribulation such as has not been since the beginning, neither shall be.” For this is the last contest of the righteous, in which, when they overcome they are crowned with incorruption.
Nay, even in terms, and most clearly, the Scripture says, “Pray for kings, and rulers, and powers, that all may be peace with you.” For when there is disturbance in the empire, if the commotion is felt by its other members, surely we too, though we are not thought to be given to disorder, are to be found in some place or other which the calamity affects…There is also another and a greater necessity for our offering prayer in behalf of the emperors, nay, for the complete stability of the empire, and for Roman interests in general. For we know that a mighty shock impending over the whole earth – in fact, the very end of all things threatening dreadful woes – is only retarded by the continued existence of the Roman empire. We have no desire, then, to be overtaken by these dire events; and in praying that their coming may be delayed, we are lending our aid to Rome’s duration.
Who has yet beheld Jesus descending from heaven in like manner as the apostles saw Him ascend, according to the appointment of the two angels? Up to the present moment they have not, tribe by tribe, smitten their breasts, looking on Him whom they pierced. No one has as yet fallen in with Elias; no one has as yet escaped from Antichrist; no one has as yet had to bewail the downfall of Babylon. And is there now anybody who has risen again. – ibid
Perhaps some one may now ask when these things of which we have spoken are about to come to pass? …The subject itself declares that the fall and ruin of the world will shortly take place; except that while the city of Rome remains it appears that nothing of this kind is to be feared. But when that capital of the world shall have fallen, and shall have begun to be a street, which the Sibyls say shall come to pass, who can doubt that the end has now arrived to the affairs of men and the whole world? It is that city, that only, which still sustains all things; and the God of heaven is to be entreated by us and implored – if, indeed, His arrangements and decrees can be delayed – lest, sooner than we think for, that detestable tyrant should come who will undertake so great a deed, and dig out that eye, by the destruction of which the world itself is about to fall.
Then the last anger of God shall come upon the nations, and shall utterly destroy them; and first He shall shake the earth most violently, and by its motion the mountains of Syria shall be rent, and the hills shall sink down precipitously, and the walls of all cities shall fall, and God shall cause the sun to stand, so that he set not for three days, and shall set it on fire; and excessive heat and great burning shall descend upon the hostile and impious people, and showers of brimstone, and hailstones, and drops of fire; and their spirits shall melt through the heat, and their bodies shall be bruised by the hail, and they shall smite one another with the sword. The mountains shall be filled with carcasses, and the plains shall be covered with bones; but the people of God during those three days shall be concealed under caves of the earth, until the anger of God against the nations and the last judgment shall be ended. – ibid
