This article puts Schleiermacher and Tillich in confrontation. It argues that the similarity between them is superficial, for they in fact lead to two opposite directions in their approaching Christology. The resistance to transformation within a conceptual Christology, as displayed by the Scholastics, is indeed the primary concern in Schleiermacher's discussions. And he insists that only Christ's redemption which imparts the God-consciousness to us is able to lead to breaking up the resistance. In contrast, by emphasizing the role of reason in theological discussions, Tillich bases his understanding of incarnation upon certain concepts, which logically self-assume absoluteness and block criticisms. The negative attitude to reason by Schleiermacher allows the further development of reason, while Tillich's affirmative attitude indeed tends to close the door.
