Abstract
This article intends to point out that the questions about the language and the truth in Martin Heidegger’s Philosophy allow to reflect on the religious discourse. This link between philosophy and religion is made possible from the philosophy of the German thinker based on four premises: a) the philosophical concept for facilitating such reflexion is that of the onto-theology, b) this concept focus on the concept of ground, c) the structural nexus between ground and supreme being is the entry point for God into the philosophy, d) in this way the onto-theo-logy becomes the fundamental mode of the metaphysics, object of criticism by the philosopher of Messkirch.
