The article delves into the analysis of philosophical reception of Kantian ideas by representatives of the onto-logical school of the Moscow Theological Academy F.A. Golubinsky and V.D. Kudryavtsev-Platonov. I. Kant’s critical philosophy aroused genuine interest among professors of theological academies, since Kantian tran-scendentalism was a method rather than a competing system of philosophical metaphysics, nevertheless, at-tempts to combine the achievements of Kantian thought and theistic attitudes revealed obvious contradictions between the constants of the two systems. The influence of Kant’s critical thought on the philosophical tradition of the Moscow Theological Academy is assessed by researchers in a mixed way: they note the doctrinal ap-proach in criticizing Kantian positions, as well as the eclectic nature of academic concepts, in which thinkers tried to strike a balance between the rigor of Kantian discourse and the postulates of Orthodox Christian theism. Meanwhile, the critical assessment of the ideas and concepts of Kantian philosophy, the reinterpretation of its terms did not lead academic thinkers beyond its basic principles. The author notes the systemic nature of the influence, which consists in the branching of the method and structure of I. Kant’s speculative thought in the philosophical constructions of the ontological school.
