Religion is an interesting scam. Before facebook or Truth Social, prehistoric people had to rely on popular rumor for direction in their lives, whoever controled the rumor controled the people. What happens when I die? Well you have this thing called a soul that you need to entrust to a proper authority (definitely not the devil) along with financial support or you burn in hell for eternity. Always trust the official rumor. By the way, it's entirely true that preparation of Holy water requires inclusion of a grain of salt.
