Everything has to evolve, even religion; but in the area of religion, more than in any other, human beings tend to believe that precepts and rites instituted centuries ago are valid for all eternity. No, it is a mistake to think so.
Everything evolves, everything advances. Look how fast modern science is evolving! Yes, science evolves but religion does not.
Why are scientists always making new discoveries? Because they do not believe; they doubt, and it seems that their doubts spur them on to further progress. Whereas the religious believe, but faith – when it is not alive – makes humans stagnate.
Moreover, we can no longer even call this faith; it is superstition or fanaticism.
