When Paul arrived in Rome under house arrest he invited the leading Jews there to hear him explain that he was not trying to destroy Judaism. He assumed the Jerusalem Jewish leaders had already warned them about him. But this was not so. Once again Luke the writer shows it was not the mainstream Jews who were the enemies. Now, not even their leadership was trying to destroy him.

The Jews in Jerusalem told Paul that their major conflict was with a "sect" (called by Ananias the "Nazarene Sect"). In fact the Emperor had expelled all Jews from Rome because of such conflict.
Neither Paul (nor James and the elders) identified with this "sect". But apparently the sect, to be found amongst the "tens of thousands of believing Jews who were also zealous for the law," identified with them. They had been trying to take control, not only of the early Church but, according to the Jews in Rome, of Judaism itself.

The extent to which this "sect" continued on and was responsible for the stand taken by Jews in 70AD which resulted in the destruction of Jerusalem is something for the historians to figure out. The overlap between the "Nazarene Sect" and the Essene Sect is a likely place to search.

In the meantime we find that Luke has set up the "stage" for the theology of the Gospel of John.

He has shown how authority is to be found in the wide range of people.
A "living voice or Word" is to be found amongst a wide range of people as well and this is linked with the
Divine "Word".
The "Way" of Christianity is to "raise the bar" of the three basic social commandments
c/f stealing, adultery and the destruction of others.
A major challenge for the Church into the future will be to confront its "enemy within".
