Depends on the area, but I live in the Southeast where churches are plentiful and my local church (which I don't attend since I'm agnostic) has a drive up food pantry staffed by the neighborhood. I contribute to it as well. They also provide housing for people on hard times and like to come together whenever anyone is widowed and made an orphan. They've even raised money for cars for people who are struggling to make a living. They frequently raise money whenever someone needs healthcare and often times the needs of the community are met just by local experts donating their time. Many folks are blue collar and may come together to repair a house/driveway/roof. etc

Churches can be pillars of a community if done correctly.
