Some christians seem to want a communalism like we read about in Acts, so why not socialism?
Socialism is the effort to create a communal economy. So, is there a workable application of communalism, as some Christian's like to imagine being possible?
Sure, it seems to be possible in 'small' groups, the 'family' being one. But just as our example in Acts shows, Judeo Christian theology also points out that 'all men are sinners' - and sure enough some will try to cheat and lie, as did Anninias and Sapphira.
Small communal groups such as the Jews, other tribes, and groups such as the Amish have to rely on extensive legalism to avoid mass cheating, or spoiling of the system.
Another problem is that Christian's weren't called to isolate ourselves from the rest of society. We shouldn't assume that we can impose our law's on the secular and non Christian, so without our communal Christian ''legalism' a community of both the secular and Christian wouldn't work for long.
Just the same; the secular forms of socialism wont work for the Christian because the secular laws don't care about Christian beliefs, they may even be antithetical to one another. This is why popular Communist manifestos eventually oppose or even outlaw Christian beliefs and even jail and persecute Christian's.
