With regard to the pomp and ceremony:
I can understand how, in pre-industrial times, the interior of the local church might be the most uplifting thing that the lower end of society ever set eyes on and would only ever be topped if they went on pilgrimage to some even larger church-owned building. So, a weekly highlight, a social get-together, a sing-song, a bit of drama from the pulpit: practically an entertainment event.
These days, the bling looks like an ostentatious display of wealth. Whilst, on the one hand it is an insult to the poor that church income was spent on baubles instead of providing practical help to the needy, on the other, the church would look spartan without it. A puritanical attitude to church assets also scares the crépe out of people because we all know what killjoys they were, back in the 17th c. Life becomes unliveable if you're in constant fear of infracting rules which they haven't told you about until after you've broken them.
What present-day entity does that remind me of?
