The results indicated that Tillich comprehends religion as the state of being grasped by an ultimate concern which contain the answers to the questions of the meaning of life. Besides, the outcomes showed that religion is dialectically and intimately related to theology, culture and philosophy. Furthermore, the paper stipulated that religion encompasses other disciplines of religions which include and not limited to Christianity, Islam, Judaism, African, Comparative, Oriental and Contemporary. Consequently, all these religions contain a theology and a philosophy which unites or separates them.

This paper established that every religion in this biosphere communicates to the world through the lenses of philosophy and theology. Subsequently, these outcomes will be useful as a resource and reference material in the teaching of Universities both at graduate, post graduate and undergraduate levels especially in courses such as; New Testament in the modern scholarships, contemporary theologians, contemporary theology and contemporary religious thought.
