6. We ask ourselves what advantage can be gained from the multitude of parables whose meaning remains impenetrable? It must be noted that Jesus only expressed Himself in parables in areas which were rather abstract in the doctrine. But having declared charity to one's neighbour and humility as the basic conditions for salvation, everything He said in this respect is completely clear, explicit and without any ambiguities. This is as it should be, this being a rule of conduct, a rule that everyone had to comprehend in order to be able to observe it. This was the essential point for the ignorant masses to whom He said only: "This is what you need to do in order to reach Heaven." On other matters He only disclosed His thoughts to His disciples. This was because they were more advanced, both morally and intellectually, so that Jesus could initiate them in the knowledge of more abstract truths. This is also why He said: to those who already have, even more shall be given (See chapter 18, item 15).
Nevertheless, even with the apostles He was not precise on many points, the complete understanding in these areas being reserved for later times. It was these parts which caused so many diverse interpretations until science on the one hand and Spiritism on the other hand revealed the new laws of Nature, so making the real meaning perceptible.
