More and more I wonder why we have acted as though Christianity supercedes Judaism, even though Jesus never relinquished his Jewish faith, nor did the apostle Paul. Not long ago Anne Coulter blithely told a Jewish interviewer that Christians are "perfected Jews." Coulter is a truly arrogant women, but we have often shared and expressed that arrogance in a more polite fashion.
I just bought a book of essays called The Ways that Never Parted about the relationship between Jews and Christians in the Middle Ages. I'm sure it will be helpful and the title encourages me.
