Rabbi Byron L. Sherwin, once noted that many Jews seemed convinced that since traditional Judaism is focused on Halachah, i.e., the practical observance of the commandments, any discussion about theology is superfluous. Some go as far as to say that traditional Judaism does not have a theology. The problem, of course, is that any discussion about God, the Torah, and the people of Israel immediately raises fundamental questions such as which God are we discussing, how was the Torah revealed, who are the people of Israel, etc. All these questions are the domain of theology, the study of religious beliefs.
