5. Spiritism is the new science which has come to reveal to mankind, by means of irrefutable proofs, the existence and nature of the spiritual world and its relationship with the physical world. It appears not as something supernatural, but on the contrary, as one of the living and active forces of Nature, source of an immense number of phenomena which still today are not fully understood, and because of this they are relegated to the world of fantasy and miracles. Christ alluded to this situation on several occasions and it is the reason why much of what He said remained unintelligible or has been wrongly interpreted. Spiritism offers the key by which all can easily be explained.
