If Nero would not have led such strong persecutions against the original followers of Jesus, there would be no Christianity as you know it to day.  Christianity would have remained a small sect in Judaism, and would have eventually died out just like the other messianic movements of the day.  If it wasn't for the fiddle playing arsonist there would be no Easter, and there would be no Christmas. 

Nero laid the ground work for what later became modern day Christianity by killing off the original followers of Jesus and their message, but without Paul the Greek Scribe, Titus and his heavenly father Vespasian, and later Constantine, there would certainly be no Christian Church today.  Imagine how different the world would be today if there never was such a thing Christianity.  These are the very men we have to thank for the Crusades, the Inquisition, and the Holocaust. 

Christianity as we know it today got its start two thousand years ago when Paul came from his homeland in Greece to Jerusalem.  Paul converted to Judaism, and later tried to become a Pharisee, but he failed miserably.  This caused him to become very Anti-Semitic and take his frustrations out on an entire race of people. 

Paul created Christianity for two reasons, the first was to get back at his former boss, which was none other than the High Priest himself.  The second reason was to achieve the success and fame he never had when he was working for the corrupt Roman controlled High Priest.

The quote listed above is from the Ebionites, aka  the original followers of Jesus.  Paul wanting to marry the daughter of the priest is symbolic for Paul wanting to become a Pharisee, and as this quote says, Paul failed, this caused him to become very angry and write against the Torah.
