Religious rituals are meant to connect with the divine. The idea being they are not inventions of ordinary people. Some created superstition just gives some order in someone's life and is just a shadow of a proper ritual.
You seems to be reasoning that rituals are _not_ inventions of ordinary people where as superstitions are, hence one should give more credence/weight to rituals. My point is rituals are creations of ordinary people, just that they are ceremonious doesn't make them any higher truth.
