>>What would you do if you discovered that you are the Antichrist
That Jesus himself is the Antichrist. That is, judging by the gospels that have survived to this day. A normal Christ would never advise selling all one's real estate and possessions and giving all of them to the paupers; only a villain could give such evil and foolish advice. And such charity never elevated the paupers to the level of the poor.
I believe that Christianity was artificially created by the Jews of Judaism in order to destroy the main religion of the Roman state, Hellenity, with the aim of separatism, with the aim of separating Judea from the Roman state and giving it the status of an independent country.
