The Christians tried to separate themselves from the Jewish crowd so they wouldn't be the recipients of the persecution of the Romans. And the way they did it was to say, the Jews killed our hero too. And so Christians began to define themselves over against the orthodox party of the Jews as a way of surviving against the Roman onslaught.
My dad's a history buff, and I spent a lot of time on Hadrian's Wall. I became fascinated by the idea of what was so terrifying up there that the Romans built a 60-mile long, 30-ft-high stone wall to keep it out.
