Finding similarities and differences in interfaith dialogue

This week I encountered a new term, "Judeo-Islamic tradition." It occurs in an interview with Mark Cohen in the latest issue of the Princeton Alumni Weekly. He states:

The term “Judeo-Christian tradition” only became popular after World War I and especially after the rise of Nazism in Europe. In fact, Judaism is much closer to Islam in its belief system and practice than it is to Christianity. My emeritus colleague Bernard Lewis coined the term “Judeo-Islamic tradition” to describe it.

I think this illustrates a profoundly important difference. Islam and Judaism are based on law. Christianity is based on grace.
