Early Christian Views on 666 and the Beast
Early Christians read 666 as the beast’s number in Revelation and linked it to the coming Antichrist. Irenaeus, Hippolytus, and later writers like Cyprian treated the beast as a real end-time threat tied to worship and the mark. They agreed on the number, but they did not all agree on the hidden name behind it. Some passages are direct, while others are only background or broader end-times teaching.

What did early Christians believe about six Hundred Sixty-Six and the Beast?
Early Christian writers treated 666 as the beast’s number from Revelation and linked it to the Antichrist. Irenaeus in the second century says the number is six hundred and sixty-six and warns that some copies had altered readings, while Hippolytus in the third century also quotes the beast passage and explains the number as the beast’s hidden name. Later writers such as Cyprian and Victorinus keep reading the beast as a real end-time power tied to worship, the mark, and persecution.
The main evidence is broad and consistent on the number and the beast, but the exact name behind 666 is mixed, with Irenaeus offering possible names without certainty.

Irenaeus, Against Heresies: Book V Direct teaching
In this beast, when he arrives, all kinds of iniquity and every deceit are gathered, so that all apostate power, flowing into and confined within him, may be cast into the furnace of fire. Therefore, it is fitting that his name bears the number six hundred and sixty-six, since he embodies all the wickedness that occurred before the flood due to the apostasy of the angels. Noah was six hundred years old when the flood came upon the earth, sweeping away the rebellious world because of that infamous generation in Noah's time. The Antichrist also embodies every error of false idols since the flood, along with the killing of the prophets and the destruction of the just. The image set up by Nebuchadnezzar was sixty cubits tall and six cubits wide; Ananias, Azarias, and Mishaell, who refused to worship it, were thrown into a furnace of fire, prophetically indicating the wrath against the righteous that will arise towards the end times. That image, in its entirety, prefigured this man’s arrival, decreeing that he alone should be worshipped by all men. Thus, the six hundred years of Noah, during which the flood occurred because of apostasy, and the dimensions of the image for which these ju

Hippolytus, Treatise on Christ and Antichrist Direct teaching
... has also pointed to his name in a hidden way by means of a number, we will go on to explain more clearly what relates to him. John speaks in this way: "And I saw another beast coming up out of the earth. He had two horns like a lamb, and he spoke like a dragon. He used all the power of the first beast in his presence. He made the earth and those who dwell in it worship the first beast, whose deadly wound was healed. And he did great wonders, so that he even makes fire come down from heaven to the earth in the sight of men. And he deceives those who dwell on the earth by the miracles that he had power to do in the sight of the beast. He tells those who dwell on the earth to make an image to the beast that had the wound by a sword and yet lived. And he had power to give life to the image of the beast, so that the image of the beast would both speak and cause all who would not worship the image of the beast to be killed. And he caused all people, small and great, rich and poor, free and slave, to receive a mark on their right hand or on their forehead. And no one could buy or sell except the one who had the mark, the name of the beast, or the number of his name. Here is wisdom. Le
How did early Christians understand the beast’s mark?
They read the mark as part of the beast’s demand for worship and loyalty. Hippolytus says it keeps saints from buying or selling without first sacrificing, and Cyprian quotes the warning that those who worship the beast and receive its mark face God’s wrath.

Hippolytus, Treatise on Christ and Antichrist Direct teaching
...r he says, "And he will cause all, both small and great, rich and poor, free and bond, to receive a mark in their right hand or in their forehead, that no man might buy or sell, except he that had the mark, the name of the beast, or the number of his name." For, being full of guile, and lifting himself up against the servants of God, with the desire to afflict them and persecute them out of the world because they do not give glory to him, he will order incense-pans to be set up by all everywhere. This will be so that no man among the saints may be able to buy or sell without first sacrificing. For this is what is meant by the mark received upon the right hand. And the words, "in their forehead," indicate that all are crowned and made to wear a crown of fire, and not of life, but of death. For in this way too Antiochus Epiphanes, the king of Syria, the descendant of Alexander of Macedon, devised measures against the Jews. He too, in the exaltation of his heart, issued a decree in those times that all should set up shrines before their doors, and sacrifice, and that they should march in procession in honor of Dionysus, waving ivy garlands. And those who refused obedience should be
