I've seen this come up twice recently - the idea that if an issue is one of 'justice' then automatically it's an issue where the government should intervene.
I disagree, of course. I think the government can reasonably be involved in some issues of justice, sure - but I think what's going on here is that people want to get to the 'and now the government should get involved!' part of the discussion as soon as humanly possible, spending as little time as they must on ever discussing (or justifying) such intervention. So we're starting to see 'Justice means the men with guns need to be in on this!'
Respectfully, no. It does not. Human beings can and should handle some issues of 'justice' without the government doing a damn thing. Again, this seems pretty central to the Christian view as Christ communicated it.
