The point of departure of this article is Martin Heidegger’s relation to two core problems of theology today: representation and transcendence. Concerning the first issue, it is known that Heidegger provided a thorough critique on representation as ontotheology. But as for the second problem, transcendence beyond representation, Heidegger remains ambiguous. His concept of Ereignis can be considered as both a transcendent and an immanent event. In the second part of this article, I try to ‘resolve’ this ambiguity in confronting it with Deleuze’s purely immanent ontology. What comes out is a redefinition of transcendence in Heidegger ánd Deleuze as a ‘transcendence within immanence’.
