I'm as atheist as it gets but there are a couple of village churches nearby I have visited occasionally - only when there is no service though. They are calm, tranquil and an escape from modernity.
I'll sit for maybe 15 or 20 minutes and then get on with my day. I am undoubtedly misusing the church but I don't mean any disrespect - I'm in the believers space after all.
Nothing will ever bring me back to faith but that doesn't mean I can't see value in these spaces which are still largely insulated from the rude clatter of life.
