Secularization is a process of partioning and diversifying a social order that once happened to be an integral whole and from whose core the sacred radiated. In the process of secularization, that whole dissolves into discrete spheres of inner and outer, private and public, holy and profane. In this process, the divine sovereign is transformed into wordly procedures; multiple separate powers replace the absolute integrity of the sacred in meanings as well as in function.
