Bad dreams and ominous prophecies, fear of breaking commandments and church dogmas, hatred and cruelty towards heretics, temptations and possession by demons, obsessive visions, horror of curses and damage - why the religion of love has made some believers the light of the world and the salt of the earth, and turned others into neurotics and cruel persecutors of their own kind, zealots of pure faith, afraid of the dark principle? How to increase the number of the former and help the latter get rid of destructive fear? “Christianity and Fear” is the fundamental work of the Swiss psychoanalyst, student of Sigmund Freud, teacher and pastor Oskar Pfister (1873–1956), written in 1944 and published for the first time in Russian.
