I’m not sure if it’s the specific faith that matters. Much of the sense of community being discussed was provided in the West by Christian churches until recently.

Just requires a shared belief and value system of some sort compatible with building communities.

I think this atomization, as well as a lot of other things that are distinctive about the West, came about at least partly through Christianity. For example, consider the "unprecedented inner loneliness" that Weber found in Calvinism.
