The One Who Comes In His Own Name (John 5:43)
First of all, the only definition we have in the entire Bible of who the antichrist is, comes from John. Read it:
18 Children, it is the last hour; and just as you heard that antichrist is coming, even now many antichrists have appeared; from this we know that it is the last hour. 1 John 2:18 (NASB)
22 Who is the liar but the one who denies that Jesus is the Christ? This is the antichrist, the one who denies the Father and the Son. 1 John 2:22 (NASB)
3 and every spirit that does not confess Jesus is not from God; this is the spirit of the antichrist, of which you have heard that it is coming, and now it is already in the world. 1 John 4:3 (NASB)
7 For many deceivers have gone out into the world, those who do not acknowledge Jesus Christ as coming in the flesh. This is the deceiver and the antichrist. 2 John 1:7 (NASB)
The antichrist is anyone who does not recognize the incarnation and deity of Christ!
So with that definition in mind, you can eliminate all but a few of the OT passages above (how can any of them be antichrist when He hadn't come to earth yet?).
Those that remain either point to Nero (Daniel 7), Titus (Daniel 9) or are fulfilled in those who sought to crucify Christ Himself (John 8:44).
Of the NT passages, all either refer to Nero (the "beast") or do not point to a single individual at all! ("The one who comes in his own name" can refer to anyone then or now! It refers to false prophets!)
And the rider on the white horse in Revelation 6 (not 5!) is a spirit, not a person! (See Zechariah 6:1-8!)
But more to the point: every one of the verses the author of this list cites has been ripped completely out of context. As such, this is nothing more than a list of names the author points to as being one person who has yet to appear, even though the context of these passages and histories of these people show them either to be historical figures, or groups of people that oppose Christ (John 8:44).
In short, this list is nothing more than the result of twisting scripture out of context and contorting it to fit a doctrine that could not otherwise be supported without such silly semantic tricks.
For what it's worth.
