This article is a study of Hegel's distinction between religion and philosophy. The author concentrates on Hegel's publications of two periods which are Die Phanomenologie des Geistes and Vorlesungen uber die Philosophie der Religion. It is divided into three parts: In the first part, the author tries to explain, from Hegel's point of view, how does religion appear in consciousness. According to this explanation, the spirit comprehends religion because it requires an universal and static essence and tends to be unified with this essence. In the second part, the author analyzes Hegel's distinction between religion and philosophy. On the basis of this analysis, a relation of sameness and difference between religion and philosophy is acquired: when philosophy takes religious objects as its contents, it serves and criticizes religion; when religion intends to be orthodox, it tries to endorse itself with a rationalized metaphysics. In the third part, the author tries to use the distinction of Das Erkennen and Das Wissen explaining the reasoning of religious objects. In Das Erkennen, the religious object (the absolute) is doubted and in Das Wissen, rationality can acquire the knowledge of the absolute.
