Certainly the description of the church in Acts 2 sounds communistic. I think one of the potential benefits of a more collective interpretation of Christianity is that virtues reside not just in individuals but also in interactions and in the community itself. E.g., does the local church or cell or whatever operate collectively in a way that prefigures the way the society will be after the apocalypse/revolution?
Max Weber famously argued that capitalism emerged from Christianity, so I suppose the knife cuts both ways. Capitalism valorizes individual virtues, arguing that anyone with diligence and thrift and trustworthiness (and, more recently, creativity) will succeed regardless of social circumstances. In its strong form capitlism denies even the possibility of interactive or communal virtues, though clearly it is also premised on cooperating with some and competing against others. Capitalism as prefigurative praxis is I think pointing toward the future of the individual rather than that of the society; i.e., I will live now as I expect to live once I become a multimillioinaire. That’s perhaps why so many of the rich capitalists keep at it even after they’ve made their pile: it’s a way of life, not just a future utopia.
