There are some who say he is a false pope and Peter of Rome will the next pope after Benedict. Part of the reasoning is that popes cannot resign, as Benedict did. The real pope, Peter of Rome, will lead the church through Tribulation, according to some.
A friend thinks Francis may be Peter of Rome because it fits the idea of Alpha and Omega, the first and the last both being Peter (one called Peter by Jesus and the other called Peter by Malachy).
