I have tried to avoid the popular “Judeo-Christian” formulation – except in quotations of others who used the term. Of course, I believe the two faiths share common roots, a fact reflected in their scriptures and in the person of Jesus Christ. But I find the phrase less respectful to both traditions than it is designed to be. That is especially true in relation to Judaism, since the formulation is often invoked by Christians as a euphemism when they are really referring to their own tradition.
