Another critical issue is to determine what the teaching, text, story or myth is doing for the religion and how it is functioning. Religion gives an individual a sense of purpose and security. The belief in a divine power provides comfort to believers whether the religion is an established doctrine or a mythical story that has been passed down orally through generations. What a religion says usually functions in a couple of common ways; they define the group as a community and bring a sense of unity to the group. Religions has two majors believes or theory. The first is that they explain how the world and the universe were created. For example, in the Shinto religion of Japan, the origins of the Japanese islands are explained by the divine couple Izanagi and Izanami stirring up the ocean floor with a trident from the heavens, and the drippings became the Japanese islands. The Japanese people are also the descendants of these semi-divine beings. So the second theory explains the polemical topic of human origin. In many religions, some basic traditions exist. For instance, many religions believe that only one God exists, rather than multiple gods. This idea is evident not only in Christianity, but also in Judaism and Islam as well. In these religions, the common factor is that God s the origin and source of all existence.
