I always understood traditional catholic/orthodox/lutheran(?) theology to say that jews were once choosen, but they killed christ, so the blood of christ "is upon them and their children" and the choosen people or the people of God are not by circumisation anymore but by faith in Christ "in christ we are one, be it woman or man or slave or free or jew or greek" i think the choosen is the church now. But I think even the catholic church made adjustments, giving again more credit to christian zionism and such, that jews are still choosen people. I think the first pope say that was pope john paul the second, he apologised to jews as first pope and declared jews are still choosen people, i think the catholic church didnt fully broke with their traditional doctrine, but this where they made compromises.
