Religious economies are a novel idea with potential application in a free market economy. They bring the idea of the existence of the supernatural and concern with ultimate meanings, so ubiquitous to religions, in touch with the multiplicity of paths available to us. In Islamic Sufism, there are as many paths to God as there are individuals. A situation in which people could compare and evaluate religions, regarding them as a matter of choice, can best described as a religious economy. Just as commercial economies consist of a market in which different firms compete, religious economies consist of a market (the aggregate demand for religion) and firms (different religious organizations) seeking to attract and hold clienteles. Just as commercial economies must deal with state regulations, religious economies' key issue is the degree to which they are regulated by the state. From Stark's viewpoint, the natural state of a religious economy is religious pluralism, wherein many religious “firms” exist because of their special appeal to certain segments of the market or the population. However, just as there is incentive for a commercial organization to monopolize the market to maximize its profit, it is always in the interest of any particular religious organization to secure a monopoly, maintain its followers, and expand into new interest groups. This can be achieved, (and even then to a very limited extent) only if the state forcibly excludes competing faiths (Stark, 2001). The building blocks of Stark's ideas are the assumption of a free market, a market economy, and the key issue of rational choice theory, hand in hand with American Pragmatism. As with the history of religions, which are not and have not been free from contest and cooperation, similarities, and differences, so religious economies have not been and are not easily shaped without considering forces from within and among different economies. Religious actions, reactions, and interactions in monotheism, diversity of textual interpretations, the growth of intellectualism or counter-intellectualism, human perception of transcendence and the sacred, as well as the realities of everyday life, all imply that the idea of religious economies needs more exploration. Christianity and Islam, one dominating the West and the other the East and Africa, offer the instances of two massive markets. Each religion has more than a billion adherents and a history of sharing the monotheistic market. Both religions, in spite of Islamophobia in the West, have formed and will participate in the decline, incline, or stability of the market. This subject is timely in light of the political movements in the Middle East and monolithic misconception of Islam.
