The paper constitutes an attempt to answer briefly the question how Russian religious philosophy (so called Russian Religious Renaissance) was influenced by the philosophy of Immanuel Kant. The author tries to sum up the Russian religious dialogue with Kant, describing its different levels and discordances, if not contradictions, among them. Kant became the inspiration for Russian moral thought, but in the Russian philosophy of history he was treated as a bête noir representing all vices of rational western civilization; for the metaphysics of all-unity he was an important polemical context, while he was, in fact, rather insignificant for the religious existentialism.
