Philosophers and theologians of the 20th and 21th centuries are facing with the question "How is it still possible to talk about God after the rise of the logical positivism and Heidegger's criticism of ontotheology?" This paper is devoted to a search for the possible answer of Levinas on this question. Levinas frequently has mentioned about God more and more in his later phase of his work and showed great interest in the possibility to talk about God. His position is pronounced mostly clearly in the class notes of his last lecture at Sorbonne in the years of 1975 and 1976, edited and annotated by Jacques Rolland and published in 1983, and a 1975 paper titled "God and Philosophy." Focussing on these two writings of Levinas, first of all, the continuity of Heideggerian critique of traditional metaphysics and Levinasian philosophy of God is discussed; second, the way how Levinas tried to go beyond Heidegger's "ontological difference" is traced; third, the close relationship between the idea of the infinite and the Other on the one hand and the problem of God, on the other, is disclosed. The ambiguity Levinasian idea of God implies is shown in terms of the question "Was Levinas an athesit?"
