The term "antichrist' was first used in the most recent books of the Bible, ( 1 John 2:18) " many antichrists have made their appearance." For the early Christians, all those working against the spirit of Jesus Christ were considered antichrists. As Jesus said ( Mat 12:30) "He that is not with me is against me."
At the same time, the early church believed that there would be one individual, a single man whose evil deeds would far exceed all the others; and that this individual would make his appearance just before the second coming of Jesus. Jesus called him ( Mark 13:14) "the abomination of desolation" Paul referred to him as the ( 2 thess 2:3) "man of sin" and "son of perdition". John in his letter and in his Revelation to the church called him "the beast" or "antichrist."
All reputable scholars today believe that the antichrist in the book of Revelation was Nero, emperor of Rome from 54 - 68 AD. Nero persecuted the church with a vengeance, blaming Christians for the burning of Rome, and torturing them to death in the Forum. They became the first Christian martyrs. After Nero was forced to commit suicide, it was widely believed that Nero was still alive in Parthia (the middle east), hiding out (much like Elvis), and that he would return to reclaim his throne. As late as the fifth century AD, Lactantius (240-320 A.D.), Jerome (340-420 A.D.) and St. Augustine (354-430 A.D.) all still believed that the Antichrist would turn out to be a resuscitated Nero. That is what is meant when ( Revelation 13:12) says "the beast, whose fatal (and suicidal) wound has been healed."
The life and career of George W Bush parallels that of Nero in many ways. They were both born into wealthy and politically powerful families . They have both led a very dissolute (#1 - lust, one of the seven deadly sins) and drunken life (#2 - gluttony, excessive consumption) . Both avoided military service. Both are extremely lazy, spending most of their time vacationing outside Rome/Washington DC (#3 - sloth). They both have bad tempers ( #4 - anger) and exhibit great cruelty, having many people executed. They are both arrogant and dictatorial (#5 - pride). Nero fiddled while Rome burned, Bush took the longest vacation in presidential history just before the 9-11 attack, and when he found out the World Trade Center was burning he fled to Nebraska to hide. They both portray themselves as "compassionate conservatives" - pretending to care for the poor in order to gain political favor, at the same time bankrupting the national treasury on behalf of themselves and their rich friends (#6 -greed). Nero liked to pretend he was a great artist, bush pretends he's a Texas country boy. They both came to power illegitimately, when their mother/brother helped them cheat the legitimate winner of the election -Gore, of their rightful office (#7 - envy, the last of the seven deadly sins).
