The article is devoted to the Polish period in the life of N.S. Arsenyev, an outstanding representative of Russian philosophy. The central idea is to interpret Arsenyev's heritage of 1920s and 1930s, i.e. the time he spent teaching at the Warsaw University. The goal is to examine Arsenyev's opinions of the world, his contribution to all the related forms and expressions of Christianity, and his aspiration to bring together periods, nations, confessions, and cultures, which he considered to be useful variations.
