“People are so self centered. The anti-Christ was a roman ruler. Any thought otherwise is absurd.”
And others are arrogant...
The Antichrist will be destroyed by Christ at his return.
(Hint: That didn’t happen during the Roman period.)
Scripture doesn't say that. You're assuming that the "beast" of Revelation 19 is the same as the antichrist of 1 & 2 John.
Maybe he is, and maybe he isn't. 1 John 2:18 says that "many antichrists have already come, by which we know it is the last hour".
