How do we explain, then, that the first followers of Christ were mostly Jews?

The video seems to put all the blame on a venal religious establishment, ignoring that there were far more complex reasons why more Jews - many of whom certainly had minds that were just as independent as those of Jesus’ followers were - DIDN’T follow Him.

"How do we explain, then, that the first followers of Christ were mostly Jews?"

Because Jesus himself was a Jew, of course. A traditional, orthodox one in every sense except that he claimed to be the Messiah and the Son of God. And he said "Salvation is of the Jews". Not that salvation is given by them, but first available to them. They were first given the Word, and were intended to spread it to the rest of the world, not hide it as though only members of an exclusive club had privilege.
