The emergence of the concept of the sacred
It was during the first quarter of the 20th century that the concept of the sacred became dominant in the comparative study of religions. Nathan Söderblom, an eminent Swedish churchman and historian of religions, asserted in 1913 that the central notion of religion was “holiness” and that the distinction between sacred and profane was basic to all “real” religious life. In 1917 Rudolf Otto’s Heilige (Eng. trans., The Idea of the Holy, 1923) appeared and exercised a great influence on the study of religion through its description of religious man’s experience of the “numinous” (a mysterious, majestic presence inspiring dread and fascination), which Otto, a German theologian and historian of religions, claimed, could not be derived from anything other than an a priori sacred reality. Other scholars who used the notion of sacred as an important interpretive term during this period included the sociologist Émile Durkheim in France, and the psychologist-philosopher Max Scheler in Germany. For Durkheim, sacredness referred to those things in society that were forbidden or set apart; and since these sacred things were set apart by society, the sacred force, he concluded, was society itself. In contrast to this understanding of the nature of the sacred, Scheler argued that the sacred (or infinite) was not limited to the experience of a finite object. While Scheler did not agree with Otto’s claim that the holy is experienced through a radically different kind of awareness, he did agree with Otto that the awareness of the sacred is not simply the result of conditioning social and psychological forces. Though he criticized Friedrich Schleiermacher, an early 19th-century Protestant theologian, for being too subjective in his definition of religion as “the consciousness of being absolutely dependent on God,” Otto was indebted to him in working out the idea of the holy. Söderblom recorded his dependence on the scholarship of the history of religions (Religionswissenschaft), which had been a growing discipline in European universities for about half a century; Durkheim had access to two decades of scholarship on nonliterate peoples, some of which was an account of actual fieldwork. Scheler combined the interests of an empirical scientist with a philosophical effort that followed in the tradition of 19th-century attempts to relate human experiences to the concept of a reality (essence) that underlies human thoughts and activities.
Since the first quarter of the 20th century many historians of religions have accepted the notion of the sacred and of sacred events, places, people, and acts as being central in religious life if not indeed the essential reality in religious life. For example, phenomenologists of religion such as Gerardus van der Leeuw and W. Brede Kristensen have considered the sacred (holy) as central and have organized the material in their systematic works around the (transcendent) object and (human) subject of sacred (cultic) activity, together with a consideration of the forms and symbols of the sacred. Such historians of religions as Friedrich Heiler and Gustav Mensching organized their material according to the nature of the sacred, its forms and structural types. Significant contributions to the analysis and elaboration of the sacred have been made by Roger Caillois, a sociologist, and by Mircea Eliade, an eminent historian of religions.
