The antichrist has been around since the time of Paul.
You say -- "The antichrist has been around since the time of Paul."
It's actually the spirit of antichrist who has been around since then. that's what the Bible tells us.
HOWEVER, the one as described in Revelation 13 (up above in an earlier quote) is one and only one. He is the one who will be cast into the Lake of Fire, as described (further forward), in the book of Revelation. With that person -- who is cast into the Lake of Fire -- there is *ONE* and *ONLY ONE*.
There is a person who is coming who is the ANTICHRIST.
