I guess we’ll know for sure if Obamassiah is the anti-christ if he unveals a brilliant economic plan to solve the current global financial meltdown and introduces a new one-world currency (tongue only slightly in cheek).
The Antichrist will be extremely intelligent, charismatic, and everything else. “all the world [wonders] after the Beast” (Rev 13:3-4). It is not Obama. I do not believe that the Antichrist has revealed himself yet.
Regarding the false prophet, it is interesting that St. Hildegard (d. 1179) wrote that when the new Pope is elected immediately before the Antichrist, a cardinal will kill the Pope before he is crowned through jealousy, he wishing to be Pope himself. Then when the other cardinals elect the next Pope this cardinal will proclaim himself (anti) Pope, and two-thirds of the Christians will go with him. She notes that this Antipope as well as the Antichrist are descended from the tribe of Dan. If this private revelation of St. Hildegard turns out to be true, is it possible that this Antipope might be the False Prophet predicted in the book of Revelation (Rev 16:13; 19:20; 20:10; ch. 13 etc.) who will work hand in hand with the first “beast”, the antichrist, to subdue the world? This possibility is also clearly indicated by Margaret of Jesus (http://www.margheritadigesu.it/pagine/microchip.html; http://markbeast.blogspot.com).
Time will tell!
