Regarding Christians being just a Jewish sect foe hundreds of years.  Uh no.   Sorry.  Wrong.

Jesus was indeed born Jewish.  Some of what Jesus preached is very reminiscent of Hillels preaching no surprise, because they were members of the same tradition.  But at the time of his death, the most powerful groups and/or sects in Roman Judaea considered Jesus and his followers heretical.  This is one of the reasons Pilate didnt want to be involved it was an internal Jewish matter, as far as he was concerned.  Moreover, the protection given Christians as Jews didnt last all that long.  Jews who saw Christians as heretics pushed for the protections to be removed, and we have executions of Christians under Claudius and Nero.  Under emperors like Trajan, Christianity was only prosecuted as a crime in a dont ask, dont tell way but it was certainly considered a crime.  And from the very early stages, Christians didnt consider themselves Jews any longer.

SO, if Christians didnt consider themselves to be Jewish, proper Jews didnt consider them Jewish, and the Romans (who only began to define Christians as different *after* being told by the Sanhedrin et al. that Christians werent Jews) didnt think they were Jews, how could they have been Jewish for hundreds of years?  Just wondering ;-)

Absolutes can be awkward on the wikipedia unless you have facts to back them up and even then, if its historical, there will be other facts that might not back you and someone else is bound to know them.
