I hate to do this.
But it doesn't matter. You won't believe me anyway.
There is no "The Antichrist," at least not in the Bible. This concept is an American invention during the colonial period, and served as an external threat to compel congregations to toe the line better.
The Biblical meaning of antichrist is very simple. You know those few negative people we have in every church? The ones who form cliques, talk behind people's backs, find fault with everybody but themselves, make life miserable for every new pastor, etc.?
Well, they've been around forever, and not surprisingly Paul had trouble with them too. And he referred to them as antiChristian.
And that's all it means. There are no supernatural powers, there is no demon possession associated, there is no return, etc. There is no ONE antiChrist, there are just lots and lots of annoying Christians, as we'd expect.
