The essay is devoted to comparison of the Christian spiritual doctrine and R.Steiner's doctrine. The author investigates the fundamental discrepancies of the two creeds. In the first place, it relates to the Gospel's religious essence as Steiner understood it. S.Bulgakov concludes that Steiner's doctrine has nothing in common with the «deepening of Christianity». In fact, Steiner's doctrine becomes the substitute for Christianity, the anthroposophic distortion of the traditional dogmatics. R.Steiner's cult based on ideas of non-Christian Oriental mysticism proves to be a «religious fake». Within Steiner's doctrine there is no place for any of the most sacred for Christianity «treasures of the faith». The peculiarity of the doctrine S.Bulgakov subjects to criticism consists of the fact that Steiner makes a system of the occultism. However, the appearance of scientific approach and understanding in this case conceals one of the most dangerous delusions, «the superstition of our days»
