The spiritual quest of Klychkov and Klyuev have significant differences in 1920–1930, but we see a common philosophical, religious, ethical priorities in their works. In their theology the evident question is about the spiritual and the carnal nature of God the Father and God the Son. Actual question is the abandonment by God. There was expressed gnostic version of the creation of the world with the participation of the Prince of peace. Also there was actualized the question about the Prince of peace in human life as apocatastasis of Origen of Alexandria. The theme of evil in their works is solved as apostasia. Both describe the powerlessness of man before the carnal and sectarian temptations. The magnitude of evil in the novels of Klychkov and poetry Klyuev correlate with the words of the apostle John “the whole world lieth in wickedness”. They see the causes of person’s damage not only in social scrapping of Russian life of the 19 c., but in the original nature of the man. Among the manifestations of apostasy – unbelief, ecological disaster. Their theodicy is correlated with the views of S. Bulgakov, N. Lossky, E. Trubetskoy. There was a question about the atonement through the blood that correlates with biblical motifs. Klychkov and Kliuev – cosmists, their views on the world are similar to the ideas of G. Lotze, J. Boehme and the Russian philosophers-cosmists. They developed the concept of integrity and identity of the upper and lower worlds.
