You get the holidays and culture, nice set of shared stories and a shared common sense. Thinking any of it is factually accurate or that god is a thing or being that actually exists is almost considered weird.
In Slovenia (where I’m from), for example, about 70% of the population identifies as Catholic, but only 25% say there might be a god. Another 30% say there’s probably some sort of greater spirit, but not necessarily god.
The American version always seemed odd to me. Believing that stuff in the Bible is factually true, not just fables with lessons ... that’s weird.
