This paper discusses the role of religion in modern society. Religion no doubt in the perception of faithful is truly the opium of the masses, it cushions the effects of living in a problem-stricken world characterized by faithlessness and hopelessness. It is the task of religion, once the other-world of truth has vanished, to establish the truth of the world. It is the immediate task of philosophy, which is in the service of religion to unmask self-estrangement in its unholy forms once the holy form of human self-estrangement has been unmasked; religion provides a vent and creates a disconnect between man and hopelessness while reminding us of a life in the hereafter, it absorbs the heart of the pounds of suffering, and puts on man a garb of hope which will get to be shown off on the spiritual and mundane runway. The data used in the study are derived from three sources: a structured questionnaire, documentary sources, and direct observation. The findings revealed that religion as a tool for integration has played more divisive roles than integrating roles and that either in terms of its facilities, personnel, or programs, religion is not predisposed to performing the original function it set out to accomplish. After making short and long term recommendations, it was concluded that, in order for religion to effectively discharge its responsibilities, fundamental steps must be taken to control the socio-psychological basis of religion.
