This may be a cultural thing, but inviting someone to go to church would be at least astonishing in France (and the rest of Europe). This is just not the place you go for a date.
There could be some circumstances where this is possible ("hey, my church has its annual fiesta, plenty of people dressed up in a traditional way - you know, the famous one! Wanna come see that?", or a marriage/baptem/other family / friends gathering) but this is not the first place which come to mind when thinking about dates.
In some countries that still plays very badly and it could change your relationship forever.
In the USA, which is an extraordinarily religious country versus other Western countries, the response is likely to be more nuanced, but there are sill the many matters of which religion, sect and so on to consider. Going to a (particular type) of church risks being seen as a political statement as well. Best to avoid.
Ah I see. I guess location context is important. It seems odd to me as I live in NZ a very secular country, with little to no political implications of church attendance.
If anything I'd expect to get ridiculed for believing in something science couldn't prove.
I live here in NZ too, and yes we have to be careful the other way - not to ridicule someone else's belief. There are a lot of religious people here, but religion is not something that people take to work.
I had a high school German teacher who said politics and religion were two taboos for polite American conversation, but Europeans can have more civilized discussion about these topics.
Politics yes, and I would not say that it is very civilized, so people avoid it not because of political correctness (so to speak) but rather because these discussions tend to get heated.
