In Christian End of Days theology, the Antichrist, or anti-Christ (Greek: "against the Messiah"), is a person prophesied by the Bible to oppose Christ and substitute himself in Christ's place before the Second Coming. The term (including one plural form) is found five times in the New Testament, solely in the First and Second Epistle of John. The Antichrist is announced as the one "who denies the Father and the Son."
The similar term pseudokhristos or "false Christ" is found in the Gospels. In Matthew chapter 24 and Mark chapter 13, Jesus alerts his disciples not to be deceived by the false prophets, who will claim to be Christ, performing "great signs and wonders". Some other images often associated with the Antichrist are the "little horn" in Daniel's final vision, the "man of sin" in Paul's Second Epistle to the Thessalonians, and the "beast from the sea" in the Book of Revelation chapter 13. This last is possibly the definitive image of the Antichrist in popular culture, spread by literary works of which the Left Behind Series is arguably the best known. Yet none of the Greek words translatable as Antichrist appear in any of these sections of Scripture.
Antichrist in Alpha and Omega
As events around the world heralded the End of Days, conflicting evidence pointed to Judaism, Christianity, and Islam as being the one true religion. Many people suspected that the Antichrist was on Earth, and was the author of all this confusion.
