SEPARATION FROM THE SYNOGOGUE IN ROME

The first Christians of Rome were Jews or Sebomenoi (Godfearers),who were gentiles attached to the synogogue but not total converts. To become a convert, or a proselyte, would be to adopt the Law of Moses with all its prohibitions. They believed that by faith in Jesus a new covenant was established with Him, one that offered the free gift of salvation by His death on the cross. No longer were they under the bondage of  adhering strictly to the Law of Moses, but walked in freedom from works by faith in Jesus.

Because of this, the synogogue in Rome began to divide into two distinct groups: Judaism and Christianity. The synogogue could not support or tolerate such a division in belief.

HOW DID CHRISTIANITY REACH ROME FROM JERUSALEM?

Christianity spread along the routes that Judaism had already passed through. Because Puteoli, south of Rome and just north of Naples, hosted the only pre-Christian Jewish settlements in Italy known, it would follow that Christianity emerged from out of the Jewish Synogogues. The stretch from Puteoli to Rome in the first half of the first century was the main trade route between the east and the city of Rome. This is typically how the eastern traditions were introduced to Rome, the worlds capital city of its time.
