Influence of Spiritism on Progress
798. Will Spiritism become a widespread belief, or will it continue to only be accepted by the minority?
“It will definitely become a widespread belief, and will mark a new era in the history of humankind because it belongs to nature and the time has come for it to be recognized and accepted by human knowledge. It will have to withstand fierce criticism prompted by selfish interests rather than by conviction, because there are individuals whose interests lie in tearing down this belief, some out of pride, others for material motives. Its opponents, however, will be forced to join the general consensus, or otherwise risk undermining their own efforts.”
Ideas are only transformed over the course of time, never suddenly. Flawed ideas are weakened over successive generations, and end up disappearing little by little along with those who professed them. They are replaced by other individuals with new ideas, as is the case in regard to political ideas and principles. Look at paganism: no one today professes the religious ideas of pagan times. Yet, they left traces that could only be erased by the complete rebirth of the human beings who supported these beliefs for several centuries after the dawn of Christianity. The same will happen with Spiritism. It has been making considerable progress, but healthy skepticism will persist for two or three generations that only time will be able to break down. Nevertheless, its progress will be faster than that of Christianity, because Christianity itself clears the way for it and serves as its basis and support. Christianity had to destroy prior beliefs; Spiritism only has to build up from there.
