Hello
The beasts of Daniel. 7:2 are the four winds of heaven, i.e. spirits, i.e. angels that have rebelled against God.
The "beasts" rising up out of the sea, i.e. humanity, are people groups, kingdoms and empires, that manifest the domain characteristics of the respective beasts.
The Little Horn, exercises dominion over the four beasts.
In Daniel. 7:7-8 the little Horn is associated with the fourth beast and this beast is manifested in the people groups that follow the Islamic religion.
In Daniel. 8 the little Horn is associated with the Third Beast, which has 4 heads, during the 2,300 years of the Gentiles trampling the Sanctuary of God and His earthly hosts.
At the end of this age, God has prophesied that the Heavenly hosts in heaven and the kings of the earth will be judged and both the Heavenly Hosts and the Kings of the earth will be imprisoned in the (Bottomless) pit for many days to await the time of their punishment at the end of this present age. We are also told that the Bottomless pit will be unlocked for a little while when they will attempt once more to upsurge God before they are again captured and dispatched into the Lake of fire just before the end of the Millennium Age.
To claim that the Papacy is the first beast came into being when the German princes tried to demonise the Papacy and the Roman Catholic Church to assist them to remove the Papacy's power over them during the time of the reformation.
Sadly this desire to demonise the RCC and the Papacy still persists in some Christian denominations today.
Shalom
