Rudolf Bultmann?s name has a direct connotation with Heidegger. In this paper we will tackle the Bultmannian theology in harmony with Heideggerian existential hermeneutics. It is well known that after E.Husserl, Heidegger transformed phenomenology into a sort of existential hermeneutics, which has the characteristics of theology. In his lifelong endeavor to understand and expose the hidden meanings of Bible Bultmann, suggested that it was necessary to use Heideggerian existential rhetoric and terminology in order that a hermeneutical explanation of it could be grasped. So the Heideggerian terminology gets a full blown theological color in Bultmann. The following papers tries to evaluate the link between revelation, existential interpretation of the text and the demythologizing effort of Bultmann.
