How is a Jew that disdains Jesus Christ and refuses to acknowledge His Messiahship, "Chosen" exactly?
I believe that the Jews are still God's Covenant people. Scripture tells us that He used the Jews to bring the Messiah to the Gentiles. I've read nothing in the Scripture that holds that their collective rejection of Christ means that they're no longer God's Covenant people. And, as I said earlier, my reading of Romans leads me to the conclusion that God wants them to accept Christ.
You sectarians have such a quaint, diffuse "theology" concerning this. All the more humorous because two generations ago, Jews were "Christ-killers" as far as you were concerned.
Well, I can't speak for all "sectarians"; I'm a Protestant, and a Baptist. And, "two generations ago" I wasn't alive, so it would be hard for you to say anything "as far as [I was] concerned."
I think until Vatican II, it was an article of Catholic faith that "the Jews killed Christ." That's their deal, not mine. I've never held to that perverted belief, though I've known some Catholics who have.
Here's the bottom line: My sin killed Christ.
