So I overheard one person I know telling another person I know that "socialism and communism are evil and the church is very clear on that" (referring to the catholic church). And I'm trying to channel my burning frustration about it into asking what people know about communism and how it has interacted with religion more generally, but also catholicism especially, now or historically. I super hard doubt what this person said was even remotely correct, but I could believe that the catholic church takes a wishy washy fence-sitting stance because it tends to on a number of things.
At any rate, it's something I should know better because I do have catholic people in my life and so sometimes there may be a need to talk to them about these things through the framing of religion to get past the "communism is purely atheistic" type thinking.
Answers from your own knowledge or resources that go into it are both welcomed. I don't really know how to approach looking for it on my own in this instance because a lot of western religious material is probably influenced by colonizer thinking, or in the US, influenced by red scare nonsense.
Any religion is welcome. We cannot fight against religion, practice has showed us this. Religion is by definition under the influence of bourgeois control, it follows that there should be a political struggle in the religious camp as well. Liberation theology is one example of that. So if we accept people from different religious origins and beliefs in our party, it's an opportunity in following the party line on religious places of action, such as churches, mosques, sanctuaries, etc. Churches are already a place where people share an identity, it can perfectly become a place of political organization. This is well exploited by the extreme right-wing in Brazil, for instance.
