Who is one of the personalities in the tribulation?

Airline pilot Rayford Steele, his daughter Chloe, their pastor Bruce Barnes and young journalist Cameron "Buck" Williams are all characters in the Left Behind series that features the 'Tribulation'. There is a fictional pope, John XXIV, who is 'raptured' to heaven, to be replaced by his successor, Peter II, the anti-Christ and Catholic pope during the period of the Tribulation. The Left Behindseries is actually based on a theology invented by John Nelson Darby, a British evangelical preacher and founder of the Plymouth Brethren, in 1830.

The belief that Jesus will come again was not new, and Christians have always taught that Jesus will return to earth and that believers should live in anticipation of his second coming. Darby's new teaching was that Christ would return twice. The first return would be in secret, to "Rapture" his church out of the world and up to heaven. Jesus would return a second time after seven years of global tribulation for non-believers, to establish a Jerusalem-based kingdom on earth.
