I remember my New Testament professor in seminary thought that you couldn't make much of a case for socialism based on the practices of the Jerusalem Church, but he did think that 2 Cor 8:14 established material equality as a legitimate goal. (He was theologically conservative, but was a member of the British Labour party).
2 Corinthians 8:14 – “At the present time your plenty will supply what they need, so that in turn their plenty will supply what you need. Then there will be equality” (NIV)
In any event, just don't see "this is socialism" as grounds for condemning something. I think keeping some things on the free market, and some things within the government sphere of influence, is reasonable.
