The Dangerous Dinner
If you are a Jew as opposed to a Christian, your very self-identification tells me that you are announcing Judaism to be right, and Christianity to be wrong-- unless you are purposely following a doctrine you believe is wrong (I suppose some people might do that, but whatever for?).
I think if you're going to talk about Jews you're talking about the wrong people. I don't think Judaism works that way and if you asked Jews, last time I checked, they'd tell you they only claim a "particular relationship" with God. That isn't arrogance. That is saying they have a place in God's heart/kingdom/agenda but it doesn't exclude or disqualify anyone else from having a relationship with God.
