Is the beast of Revelation 13 the same as the beast of Daniel 7?
Put simply, one represents Rome and one represents Papal Rome, and that is why they are so similar.
The prophecies in Daniel, starting with Daniel 2, repeat the same four sequence of world kingdoms, starting with Babylon, then Greece, Medo-Perisa, and finally Rome (1). Rome is the kingdom that is depicted as continuing even unto today but is fragmented (represented by the statue's feet of iron and clay).
The prophecies in Revelation, contain the same imagery because it still refers to the same events. However, it starts from John's time, Rome, and then has a more detailed revealing of events that would follow.
Therefore, Daniel 7, the fourth beast with iron teeth, with a little horn power that emerges afterwards with its own mouth, speaking blasphemies for a time, times and half a time period (Dan 7:25) and persecuting saints, is none other than the depiction of Rome and then its new form of government during the middle ages when it existed as the Holy Roman Empire and other forms.
In comparison, Revelation 12-13, Rome is depicted in more detail as two beasts, Pagan Rome and Papal Rome.
Pagan Rome, found in Revelation 12, is the Red Dragon with seven heads and ten horn, persecuting Jesus as soon as he is born (Rev 12:3). Yes, it primarily symbolizes Satan, but the context show that it is depicting Satan's persecution through Pagan Rome.
Papal Rome, found in Revelation 13, is the beast that rises out of the sea, with elements of the kingdoms that rose before it (leopard, bear and lion forms and power given to it by the dragon - Pagan Rome). The details suggest similarity to the little horn.
- It persecutes for 42 months or a time, times and half a time (Rev 13:5), just like the little horn power in Daniel 7 (2)
- It speaks blasphemies (showing that it could be a religious entity), just like the mouth on the little horn in Daniel 7
- It persecutes saints, just like the little horn in Daniel 7
Therefore, the beast of Revelation 13 is not exactly the beast of Daniel 7, but the little horn of the beast of Daniel 7. It is the Papal Rome of the Roman Empire.
(1) Daniel 8 even names Greece and Medo-Persia by name as the kingdoms after Babylon, each represented as a separate animal.
(2) Using the day-year principal, where a day in prophecy is a year, we can see that 1260 days is not literal days, but the period of Papal power. The Pope received its power in 533, but did not have the three dissenting kingdom (three horns) destroyed until 538, and it ruled until when the French Revolution removed the Pope in 1798 (its deadly wound). Since then it currently only has religious power and not secular power.
