Dear Rabbi Zeilingold: As I told you over the telephone, I genuinely regret my inability to fly out to St. Paul to lecture to your congregation. However, I am pleased to be able to be of assistance to you in any other way. The question which you have been called upon to treat at the symposium in your community, "Is Judaism The Only True Religion?״ is a thorny one, and one which requires a good deal of preparation.

There are some Jewish thinkers today in Israel, as there were in Germany during the beginning of the Enlightenment, who maintain that Judaism is primarily a religion of law rather than of dogma or ideas.
