Jesus Christ was a rejected jew. The jews had their own beliefs. After Jesus
died and went to heaven his followers were just 11. But they had to swim
against the current. They called themselves believers. Till 64 AD when Nero was
the emperor he persecuted the christian community. He even set fire .
Christians were put to death. There was no christianity in Rome. Nero wanted
that people should adore him and burn incenses before him. Polycarp was one of
them who was put to death. Many told him to save his life by burning incessence
before Nero. Till 312 AD the christians lived a very hopless life. Then one day
Constantine King had a vision and show Christ and he won the war and from 312
AD christianity was supported by him. So actually Christianity in Rome was born
in 312 AD and I do not think Simon Peter would have lived that long to become
the first pope.
