He’s an idiot. I skipped a little forward here and there and started listening to sections of his presentation. He doesn’t know as much as he thinks he knows.
He’s not wrong, at least entirely. His understanding is incomplete. It’s based on the idea that God would not abandon His promise He made to Israel.
As I read the New Testament, Christ did come to correct the flaws that had entered Judaism since their return from exile. He didn’t come to change the Jewish faith, but to save it from itself. However, Christ did teach, in principle through the parables, that their promise from God, would be taken from them and given to those who would receive Him.
That is what the Rabbi is missing here. When Christ told the parable of the landowner, and asked what should happen to those who killed his son, it was a warning and the Jewish leaders pronounced their doom.
When I say this, I am not saying God has abandoned Israel, but it’s no longer promises made exclusively to the Jews.
