40. When he says so that he sits in the temple of God, showing himself as if he were God, he gives the sign of this wrongdoing. For the Antichrist’s pride is greater than the pride of all who came before him. So as it is written of Gaius Caesar that he wanted to be worshiped while he was still alive, and put statues of himself in every temple, and as Ezekiel says of the king of Tyre, I have said that I am God (Ezek 28:2), so it is quite believable that the Antichrist will act as they did, saying that he is both God and man. And as a sign of this he will sit in the temple.

"statues" = statuam = likenesses = portraits

Bergoglio is the Antichrist. His teaching can be found here:

1. (Dignitas infinita) Every human person possesses an infinite dignity, inalienably grounded in his or her very being, which prevails in and beyond every circuмstance, state, or situation the person may ever encounter.

"inalienable" = cannot be lost
"grounded in his or her very being" = not grounded in God

So "original sin" and the "state of grace" are irrelevant and meaningless concepts under this new philosophical anthropology. 

From books on prophecy I've read over the years, the Antichrist is a political person and the false prophet (teacher) is an apostate bishop.

Bergoglio is "a political person." In this political role, he meets with and directs world leaders. He pushes those leaders to implement "climate change" mitigation policies, suicidal immigration policies, etc. This is his "Beast from the Sea" role (Apocalypse 13:1).

The Church Fathers explain that the Antichrist will be like the Roman emperors. Those emperors did not try to insert themselves into the day-to-day running of every part of the empire. The emperors used local leaders, like Herod, to give conquered peoples the impression that they were ruled by their own rulers. But those local leaders were just puppets of the Caesar.

So, similarly, the Antichrist allows other local/regional politicians to appear to control their nations, but it is he who is actually in control. Fɾҽҽmαsσɳɾყ has used this model for many years. The freemasons control both sides of the political spectrum in all the countries.

Bergoglio is also "the apostate bishop," the False Prophet, the "Beast from the Earth" (Apocalypse 13:11). In this role, he plays the role of the Roman Emperor as the Supreme Pontiff. The alternative name of the emperor was the "Pontifex Maximus." So, that phrase, now used by the Catholic Popes was originally a Roman imperial term referring to the emperor in his role as "the high priest" of the Roman Pantheon.

These two beasts in the Apocalypse are describing two "roles" played by the same person: the Antichrist, Jorge Mario Bergoglio.
