I’m not sure how to answer this question without offending Catholics. There are a vast number of writings that attribute the system of Catholicism to the mystery of iniquity. Let’s look at what exactly Paul says.
2 Thessalonians 2: 7 For the mystery of lawlessness is already at work; only He who now restrains will do so until He is taken out of the way. 8 And then the lawless one will be revealed, whom the Lord will consume with the breath of His mouth and destroy with the brightness of His coming. 9 The coming of the lawless one is according to the working of Satan, with all power, signs, and lying wonders, 10 and with all unrighteous deception among those who perish, because they did not receive the love of the truth, that they might be saved.
Whether you are a Protestant or Catholic, both sides agree Paul’s writings are inspired. Paul physically wrote the epistle but it’s God who is giving the revelation.
Paul is given insight by God which matches exactly with Daniel in chapter 2
45 Inasmuch as you saw that the stone was cut out of the mountain without hands, and that it broke in pieces the iron, the bronze, the clay, the silver, and the gold—the great God has made known to the king what will come to pass after this. The dream is certain, and its interpretation is sure.”
In Daniel there is no doubt who the 4 beasts, and the 4 distinct parts of the statue are because 3 are told to us. The head of gold or 1st beast was Babylon. Daniel foretold who the next two beasts would be. Babylon was conquered by Medo-Persia. The 3rd beast was Greece who conquered Medo-Persia. Daniel doesn’t name the 4th beast but again we all know Rome conquered Greece.
Both Daniel and Paul tell us this 4th beast would last until Christ comes back to destroy it.
John in Revelation 19 sees this even in greater detail
20 Then the beast was captured, and with him the false prophet who worked signs in his presence, by which he deceived those who received the mark of the beast and those who worshiped his image. These two were cast alive into the lake of fire burning with brimstone.
We know for certain the 4th beast was Rome. There are no other beasts after Rome, so this power that was already working to gain a foothold in Paul’s time, (around 50AD when he wrote Thessalonians) would have to last until the return of Jesus. There’s no way around those facts. There’s no 5th beast, or 6th beast, or 7th beast etc… The 4th beast has to survive until the 2nd coming.
So the answer to the OP from a biblical point of view is the entire system of Catholicism was invented by Satan from the very beginnings of Christianity. The Son of Perdition is used only twice in all of scripture. Once to describe Judas and once to describe the ultimate AntiChrist. Wouldn’t this ultimate AntiChrist then share attributes of Judas? Did Judas lead a rebellion against Jesus and his followers? No he acted like one and betrayed Jesus with a kiss. Paul says the AntiChrist will come with all deceivableness of unrighteousness. Isn’t that what Judas tried to do?
