You simply cannot get around this fundamental point, though - sticking the boot in to the poor and needy may, in Republican minds, be a sensible economic policy, but in their wildest, most fevered dreams, can they seriously believe that it's what Jesus would have done?
From the conservative viewpoint, the justification is quite simple. Jesus' words about giving away wealth and helping the poor are an exhortation to personal charity, but don't justify using the power of the state to enforce such behaviour.
