The article examines methodological principles of studying the Russian literary canon in the cultural context of Eastern Orthodoxy, as demonstrated in I. Esaulov’s book. While acknowledging the importance of the book’s method, the article reviews and criticizes the concepts used by the scholar (the Eastern archetype, the Christmas archetype, the categories of Law and Grace, etc.). In particular, the author challenges the statement that a writer populates his works with archetypes prevailing in his culture (so Eastern Orthodox ones in the case of Russian culture), often against his own religious principles. Also subjected to critical analysis is the thesis about the Easter archetype being more specific to Russian literature, with the Christmas archetype being more typical of Western literature. On the whole, the paper argues that the transhistorical approach declared by the scholar as opposed to the rigorously historical method (M. Gasparov and others) may often lead to strained hypotheses and mythologizing; all in all, it may result in an ahistorical perception of both Eastern Orthodoxy and the literary canon.
