Well, some Jews here can't stand my being too honest! That is my impression! As Orthodox Christian I believe Jews are not chosen people anymore since I believe in the New Testament as well! I will not talk about it anymore because I don't want to upset you!
This really is no place for theological debates but since you've brought up this subject I might as well inform you on the base differences between the two faiths. There is one main difference between Christianity and Judaism which most informed Jews understand while Christians do not and will never understand unless they step back and research from an impartial view of History and also Theology. Jesus was a Pharasee (Rabbinical) Jew from Judea (not "the West Bank" in "P-lestine"), thus would have followed Othodox Judaism or Torah Law. Further he would have logically known that the Torah was given to the Jewish people at Sinai and only applicable to Israel/Jews. Further, Jesus especially but John and the rest of the Apostles would have known that Jews are beholden to the Laws of Moses while the Gentile is accountable to the base laws of a moral society: 7 Laws of Noah, thus being no need for a "New" Testament. It is impossible to believe in both the Old and New Testaments as according to the "Old" Testament the specificities affords no base for a, or any, New Testament. This is easily understood when researching both Theology and History of both Judaism and Christianity especially since Constentine and the Council of Nicea 323.
The so-called "Chosen" people has only one basic meaning. G-d "chose" one Goy (Nation) to accept the Torah, not the Romans, Greeks, Trojans, Assyrians, Egyptians, Babylonians, Hittites, Mongols, Persians, Spartans, Phonesians etc. but Yacov: Israel.
So, according to G-d's word, as specified in the Torah, the Gentile is only abliged to follow the Laws of Noah: Noahide Laws:
