I have long wondered why the Jews didn't accept Jesus -- I'm reading a book about Edith Stein and her Jewish family were very upset when she became a Catholic and more upset when she went into the Carmelite order. Of course, the first Catholics were Jews -- Peter, Paul, etc., etc. -- just wondered.
The following link should help answer your question about the Jews. If you have any further questions, please contact Catholic Answers directly.
What is the Jewish defense of not accepting Jesus as Messiah?
