This response to Mark Sedgwick's article on "Sects in the Islamic World" focuses specifically on the word "denomination," both for those groups that Sedgwick so labels and for those that I consider might be so labeled. For the Sunni/Shi'i distinction, I do not find the word "denomination" appropriate. Depending on the context, I suggest "division," "establishment," or "religious minority." The label "denomination" can be useful for either tariqas (Sufi orders) or madhhabs (schools of jurisprudence) , particularly if we want to emphasize the fact of mutual acceptance by various tariqas or madhhabs and their relatively low tension with society. It fits least well if we are concerned with the internal organization of madhhabs or tariqas. Since the term tariqa is fairly well known, there seems little point in replacing it with "denomination." For cross-cultural studies, however, "denomination" well be appropriate for both tariqa and madhhab .
