Church attendance isn't about "unifying interest" or socioeconomic status? The unified interest is obvious: salvation through christ, and churches tend to serve a relatively small community which is likely to be of very similar socioeconomic status. That's not even to mention the abject racism that led to black christians having to set up their own churches (which white people often subsequently burnt down). The olden days where "everybody" went to church every week still had tons of social problems.
