The article cites 1 John 2:18 "Little children, it is the last time: and as ye have heard that antichrist shall come, even now are there many antichrists; whereby we know that it is the last time." It claims interpretations including "there will be many small antichrists, false priests and so on, leading up to the final major antichrist." I don't know how much to trust the author's eschatology, though.
