The correct answer to this open question is the following.
The expulsion of the Jews from Rome in A.D. 49 by Emperor Claudius drastically changed the character of the church in Rome. What happened next is that the church became totally gentile.
It was precisely Emperor Claudius, the one who expelled Jewish people from Rome in 49 AD because he considered Jewish as rebellious people that causes too many disturbances in the city.
Indeed, rumors said that Jewish tried to convert Christians in some parts of Rome. When Emperor Claudius heard about this situation, he did not hesitate to expel them. The Holy Bible in the Act of Apostles makes reference to this event.
