Since the concept of"secularization"emerged,its connotations have experienced continuous evolution with the development of the West. After the 19 th century,the socio-religious circles of the West have adopted three narrative approaches to the secularization theories and related problems,linear secularization,periodic/circular secularization and multidimensional secularization,and focused their heated debates on four major problems,secularization and de-secularization,differentiation and de-differentiation,pluralism and the exceptionalism of the United States and Europe. At present,religious beliefs and practices in the West are undergoing profound changes,and a mode of religious belief between secularization and de-secularization has gradually emerged.
