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.

The attempt to study religion objectively (Religionswissenschaft) has been part of the academic scene in the West for a century. Such men as F. Max Mueller, Edward Tylor, W. Brede Kristenson, Raffaele Peettazzoni, and Joachim Wach worked to develop such a truly scientific study of religion. They held that a study of religious data could reveal what religious life means for people who participate in it if methods are used which prevent a superimposition of the investigator's personal value judgments. At the same time, there has been the recognition by some scholars, including some of the above, that there is something about religious life that cannot be investigated by normal empirical methods. This sense of the uniqueness of religion is symbolised in Rudolf Otto's book The Idea of the Holy, where he maintains that in order to understand religion in its innermost core, an investigator must recognise ‘a unique “numinous” category of value and of a definitely “numinous” state of mind’. Our concern here is to examine one problem arising from the claim that religious life must be studied in terms of its own intention, or category of value; and yet studied through an inductive method which allows for the distinctive character of different historical expressions of religion.

Genuine religion always involves the worship of what is genuinely ultimate. Religion, worship, and ultimate reality are thus indissolubly related. The task of reflective thought in this domain is to distinguish what is sound from what is spurious in religion; to characterise the meaning of religious devotion; and to attempt to articulate the nature of the ultimate reality to which men's worship is directed.

In discussing the intricate and somewhat complex relationship between Shiʻism and Sufism, both in principle and essence or in their metahistorical reality as well as in time and history, we need hardly concern ourselves with the too often repeated criticism made by certain orientalists who would doubt the Islamic and Quranic character of both Shiʻism and Sufism. Basing themselves on an a priori assumption that Islam is not a revelation and, even if a religion, is only a simple ‘religion of the sword’ for a simple desert people, such would-be critics brush aside as un-Islamic all that speaks of gnosis (ʻirfân) and esotericism, pointing to the lack of historical texts in the early period as proof of their thesis, as if the non-existent in itself could disprove the existence of something which may have existed without leaving a written trace for us to dissect and analyse today. The reality of Shiʻism and Sufism as integral aspects of the Islamic revelation is too blinding to be neglected or brushed aside by any would-be historical argument. The fruit is there to prove that the tree has its roots in a soil that nourishes it. And the spiritual fruit can only be borne by a tree whose roots are sunk in a revealed truth. To deny this most evident of truths would be as if we were to doubt the Christian sanctity of a St Francis of Assisi because the historical records of the first years of the Apostolic succession are not clear. What the presence of St Francis proves is in reality the opposite fact, namely, that the Apostolic succession must be real even if no historical records are at hand. The same holds true mutatis mutandis for Shiʻism and Sufism. In this paper in any case we will begin by taking for granted the Islamic character of Shiʻism and Sufism and upon this basis delve into their relationship. In fact Shiʻism and Sufism are both, in different ways and on different levels, intrinsic aspects of Islamic orthodoxy, this term being taken not only in its theological sense but in its universal sense as tradition and universal truth contained within a revealed form.

Of all the distinctive features of the Buddhist religion, one of the most neglected is the sangha. Scholars give much attention to the study of texts and commentaries, the analysis of doctrines and the classification of schools. But the core of the Buddhist religion is the sangha, the community of bhikkhus around whose corporate life the religion is moulded. It is the existence and structure of the sangha which has shaped the history of Buddhism, enabled it to take root in new countries, and given it the customs and rituals which have made it a religion rather than a small sect.

My aim is to examine Buber's language, especially in I and Thou, with a view to discovering how to interpret his extraordinary mode of expression; and by doing so, demonstrate that it can be at least partially explained, and related to language-forms with which we are more familiar.
