As an atheist, I don't get to many church services. However, some time ago two of my cousins got married just a fortnight apart, both with church services.
The cousin on my father's side got married in a dark and dingy CofE church, with a very traditional service, with the hymns sung (tunelessly) at a pace better suited to a funeral than to a wedding. I couldn't identify anything remotely joyous in the whole ceremony.
The cousin on my mother's side got married in a light and airy Baptist church hall though, where the first thing everyone noticed upon entering was the massive mixing desk for the sound engineer to do his work. However the children's choir who belted out 'Lord of the Dance' at full volume didn't really need any amplification; they were loving every minute of it, as were all of the congregation. The whole thing was totally joyous from start to finish.
Irrespective of whether one believes in God or not, it seems odd to me that the members of some branches of the Christian faith seem intent on 'celebrating' important events in a way which appears to be anything but 'celebratory'. The second service made sense to me; the first one most definitely did not!
