Maybe the jews dont rate being classified as a race. But I'm pretty sure they qualify as a nationality, or ethnic group, like German, Irish, polish, Italian, Jewish.
Do the Catholics qualify as an ethnic group? On the proselyte part, a lot of Jews can be proselytes under your definition because they aren't direct descendants of Abraham. The book of Chronicles (I believe?) has the list. Wasn't it kept to know the lineage of Jesus? Not every Jew is of the 12 tribes of Israel. Just Abraham's kids. Who was Keturah's (Abraham's concubine) sons? Are they considered proselytes?
The sacred story of Abraham traverses the geography of the most bitter political conflict in the modern world — beginning in what is now southern Iraq and ending in the West Bank city of Hebron. Yet Abraham is the common patriarch of Judaism, Islam, and Christianity. We explore the story of Abraham in several traditions and why he might be important for people in our time. The hour also includes readings from the Bible and the Qur'an as well as music from the likes of Bob Dylan and Benjamin Britten on the figure of Abraham. http://speakingoffaith.publicradio.org/programs/abraham/
