To say that the Mystery of Golgotha ought not be placed as a unique event in the evolution of humanity because other religions would not be able to acknowledge this fact shows complete misunderstanding. Let us consider the following. Today we have the sacred religious books of India and a modern Western world-conception. Today in the West we teach the Copernican system, and no one would suggest that we ought not to teach the Copernican theory because it is not contained in the sacred books of India! For the same reason no one can object to the teaching of the Mystery of Golgotha because it is not to be found in the religious writings of the ancient Hindus.
