Gramsci talked a lot about how communists should try to emulate the Catholic churches structural reach - we should be doing what the church does for the working class - provide community, provide a 3rd space, charity and outreach work, mass events, teaching and reading and such.

I think we can learn a lot from how religion organizes.

Im personally agnostic and respect most moderates religious beliefs, although I remain spectical I wouldn’t shut someone out or refuse to work with anyone who was religious.
