Ok I see where you're coming from.
No, I'm not saying the beast is Catholicism. I'm saying the office of the Roman Papacy; Papal Rome is the beast; the man of sin. If I had to label Catholicism, it would be the great harlot (as a congregation of people) just like the Almighty's people are his faithful bride. The great harlot rides the beast.

Revelation 17:8 & 10-11
8 The beast that thou sawest was, and is not; and shall ascend out of the bottomless pit, and go into perdition: and they that dwell on the earth shall wonder, whose names were not written in the book of life from the foundation of the world, when they behold the beast that was, and is not, and yet is.
10 There are also seven kings. Five have fallen, one is, and the other has not yet come; but when he does come, he must remain for only a little while
11 The beast that was, and now is not, is an eighth king, who belongs to the other seven and is going into destruction.
So this beast was, but then wasn't and yet will be. So we have a morphing of sorts that happens to this beast.
Letting the scriptures define the scriptures, we learn from the explanation given to Daniel that beasts represent kingdoms/empires, confirmed by the angel in verse 11. So at a basic level, we have a kingdom/empire that came to exist, where:
- Five previous world-ruling kingdoms are gone.
- The 6th world-ruling kingdom is contemporary with John...we know this was The Roman Empire. It was definitely the head/king that IS in John's time.
- The next ruling kingdom after Rome hadn't appeared in John's time, but when it appears it will have a short rule comparatively.
- Then the 8th kingdom will come from the previous and is the particular kingdom that will go into "perdition" (i.e. be destroyed by the Messiah per 2 Thessalonians 2).

Ok, so with the Roman Empire as our marker, let's compare scripture with history to prove why I believe "the man of sin" is the Papacy:
- We know The Roman Empire is the 6th kingdom
- In 395 AD The Roman Empire split into world-ruling empires: (Eastern) Byzantium & (Western) Roman Empire. So the 6th kingdom birth the 7th.
- In 476 AD The Roman Empire (western) is sacked and falls.
- In 538 AD The Papacy ascends in powers within the remaining Byzantine Empire, installed by the emperor and acquires land (i.e. the papal states) and an army. It's literally considered a sovereign kingdom, even today. 8th Kingdom of the seven.
- In 1453 Byzantium falls, but Papacy remains as a kingdom, gaining in authority, installing kings, and establishing papal bulls that sanction the persecution of 'heretics' of the faith as well as outlawing the possessing of the scriptures. He also speaks pompously blasphemous words like "Papa/Father", "Christ Vicariously", "Holds the place of God on earth"; changed times and laws, set new holy days, specifically persecuted the Jews and believing gentiles who protested their practices.
- In 1798 the papacy was ended by the French and was no longer a kingdom. But in 1929 Papal Rome was revived as a sovereign kingdom and has been with us since that time. Newspaper clippings even literally said, "wound healed".
Next, we have...
Revelation 17:12-13
12 The ten horns you saw are ten kings who have not yet received a kingdom, but will receive one hour of authority as kings, along with the beast.
13 These kings have one purpose: to yield their power and authority to the beast
So there would be 10 kingdoms that hadn't yet come to power in John's time but that would rise to power and rule for a short time as contemporaries with "the beast", yielding their authority to him.
Historically there were 10 germanic kingdoms that rose to power after the Roman empire and eventually submitted to Papal Rome (either willingly or by force), and they were:
Alemanni
Suevi
Visigoths
Vandals (extinct)
Franks
Anglo-Saxons
Heruli (extinct)
Ostrogoths (extinct)
Lombards
Burgundians
