Not only are there many particular relationships among religions to be explored, but there are many types of relationships or categories of relationships to be considered. As examples of these types we might mention historical, metaphysical, epistemological, ethical, sociological, or theological relationships without in any way being exhaustive. The prominence of some of these concerns has limited the attention given to other actual or possible relationships. For example, there has been an understandable, even justifiable, prominence given to historical relationships for the sake of accurate fact, to theological relationships for the purpose of clarifying how to think of other religions from a received confessional norm, and to ethical relationships for the sake of judging practical accomplishments and superiorities.
