The question of whether Heidegger’s phenomenological contribution to the philosophy of being originates from his pre-philosophical attitude to theology or rather, it is the methodological question of phenomenology which influenced his thinking, is one of the most essential questions in Heidegger-research. Though, this has already been elaborated on in a broader sense, the publication of the Black Notes has opened new dimensions for discussion. It is not the aim of this paper to represent Heidegger’s concept of the history of being (...) in the light of the new debates, but rather to confirm the thesis, that, in spite of the ‘turn’; in Heidegger’s thinking, his phenomenological hermeneutics was inspired, above all, by his reflection on Christianity. Moreover, the paper will question whether the linearity of Heidegger’s thinking about the historical being remains on the horizon of the religious phenomenon, as it is thematized in his early papers and lectures. While Heidegger’s early phenomenological approaches to religion and theology have been sufficiently elaborated on by several authors, and the phenomenological–hermeneutical relevance has been proven in his thinking, the linkage between the early philosophical approaches to the problem of religiosity and of historical being arising newly in Heidegger’s thinking from the 1930s is missing. The present paper will not just refer to the thesis that Heidegger’s theological background contributed to his questioning of being, and that it was influenced in different ways, but makes an attempt to reveal the internal dynamics of Heidegger’s early thinking prior to the publication of Being and Time and the time of composing the Contributions to Philosophy of those of Heidegger’s lectures which remain in the parallel analysis of religiosity and historicity.
