Were the earliest followers of Jesus Jewish or Christian?

Were the early followers of Jesus Jews, not Christians? I have seen this question posed in a number of ways and I would like to suggest the question assumes a dichotomy which is largely false, or at least not so black and white as the question implies. For the truth is the bulk of the earliest followers of Jesus were BOTH Jewish AND Christian. And it is even more complicated than that, for by the time represented by the second diagram, which is when the bulk of the New Testament was written, the Jewish Christians included both Aramaic speakers and Greek speakers within their ranks. Indeed the evidence suggests that the bulk of the New Testament texts were written by multilingual Jewish Christians with mixed audiences in mind. They were servant-leaders who served as bridges between Pagan-born Christians (who’s numbers were increasing) and Jewish-born Christians (who understood the culture of Jesus from the inside). “But the Christian label didn’t come into existence till later!” I hear some say. True enough. Before we get too carried away though remember this: Christ and Messiah mean the same thing. So we could as easily speaking of people who acted as bridges between Messianic Jews and Messianic Pagans who both centred their hopes and way of life on the Messiah, Jesus.
