Socialism?

So, it seems pretty clear that Paul instructed the members of the early church to share their belongings with each other, right? I’m pretty sure Jesus preached the same thing. Isn’t this pretty much “socialism”?  (I know it’s not actual socialism, but this is just going with the assumption that Obama’s administration is trying to turn America into a socialist country, which is of course completely false.)  And why make such a stink about the separation of church and state if both organizations (church and government) want the same thing? I don’t understand what the big deal is. Jesus told us to share our belongings with those less fortunate, and the early church seems to have been something of a commune (where they pooled their resources and helped each other out), but the “Christians” I’m hearing about in the news and whatnot are so dead-set against the government making them do this. Why, if Jesus told them to be doing it in the first place? It seems to me like they ought to be rejoicing that the government is finally in agreement with them! Please, if anyone has an explanation other than what I suspect (i.e. they’re all selfish and want to keep every cent), I’d really like to hear a legitimate, thought-out response. I’m not posting on Facebook because I don’t want to offend. I’d really like to understand.
