Analysis of Relationship between Man and God In Zoroastrianism on the base of the Phenomenological approach

One of the most important subjects in the study of religions is discussion about the nature and quality of the relation between human being and God especially because in many religions, the final happiness has founded on this relationship. In this context, Zoroastrianism with his unique approach to God, order of World, ontological status of human and morality, has prepared an obscurant view in this matter and its different aspects. This article has been founded in direction to study and analysis of Zoroastrian view and books about the nature of relation between human and Ahura-Mazda. So this study uses the descriptive-analytic method. We have proved that in Zoroastrian doctrines, the most important relation between God and Human is the ontological one. In this context human must found epistemological relation with God and in this context, he should worship God and make ordered his deeds in ground of orthodox orders, and by this he can construct the best relation with God. This kind of connection has some profits that include supporting Aŝa (divine and ethical order of the world), decay of Ahriman (evil and devil) and final happiness in hereafter. Thus, we can say that in Zoroastrian doctrines as appeared in Avestan and Pahlavi works, the juridical and soteriological relationship between God and man have their roots in ontological one.
