Well, your title to your OP is a little confusing. You use the word "Antichrists" plural, but capitalize the "A" as if you are hinting towards The Antichrist.
Anyone who denies Christ is anti-Christ. Plain and simple. And there is one way to fix that status which is to accept Christ.
On the other hand, there is a specific individual who is called "The Antichrist" and who is also referred to as The Assyrian. He will deceive all those who are anti-christ into believing that he is God and should be worshiped instead of God.
The site (usmb) arranges the lettering of titles as it sees fit, but there is no "the Antichrist" according to the Bible. THAT IS MADE UP DOCTRINE. The Bible plainly states that anyone who denies that Jesus is the Christ/Messiah is the antichrist and that is obviously VERY MANY PEOPLE.
IF only 144,000 of the Jews will be saved THEN ALL JEWS ARE NOT PEOPLE THAT NEED TO BE SPECIALLY REVERED. The rest of them (the rest other than the 144,000,) and anyone who denies that Jesus is the Christ/Messiah are antichrists.
Crikey; I went through those "numbers" years ago with a Preacher and then asked a local bloke what the f?? He then put me on to what "numbers" meant to those in the early church and it made a lot of sense; a point of information on which I and Fundis disagree. I like maths but Numerology is a world of its own.
