On the other hand, if this same professor one day accepted Jesus as his Savior and became a new-born holy roller Christian, that would become his primary cultural identity. People who went on a blind date with him would be hearing about the word of God, and not about whatever it is that City College professors talk about. In other words, if he wanted to advertise in the personals and give someone a sense of who he was, his strongest cultural signifier would be "Christian" regardless of what Mordechai of Lvov thought about it all. I don't think he would call himself a Jew anymore in any context. Of course if he went on to win a Nobel Prize, the Jews would be winking at eachother, but that is a different story.
That was an unwarranted, unappreciated jab at my faith. Watch it. It's not "new-born." It's "born again."
Have I disrespected the Jewish faith? I think not. Nor will I under any circumstance. I ask for the same respect.
Also, there is no such thing as a Christian culture.
Lastly, I haven't seen anything yet that disproves me, but, either you are ethnically Jewish or you are not. It's like being "a little bit pregnant." You either are or are not. And if you wish to deny the Jewishness of a Jew who professes faith in Jesus, how is that not blatant bigotry?
