Commentary: Who Are the Judeo Christians? Just who are the Judeo-Christians? Commentator Steven Waldman wonders about that frequently used phrase.

Judaism and Christianity share a great deal, but they exist as separate religions because of a theological rivalry. Steven Waldman is the editor in chief of Beliefnet.
