For the majority of these minor observances, almost no one showed up. Maybe you'd get a couple of old ladies but otherwise the church was completely empty. We'd be doing this elaborate stage show for no one.
It made me think of a history YouTube video I watched about some ancient religion. The priests had a complex daily ritual including setting out meals for the Gods, saying certain prayers including certain physical movements like bowing, prostrating, raising their hands. They would have to do certain cleaning rituals including incense and sweeping. Super elaborate stuff. But it was all in an inner chamber and no one would come and even watch them. They just did this ritual for no one.
I suppose I think it is interesting to see a parallel here. Like, us tech people are spiritual hermits, cargo-culting our own incantations. We're keeping a tradition alive that in only rare cases actually has an audience because we have a some faith in its utility.
