Justice and beauty are central to God's new world and should be central to our work. Together they frame the good news of Jesus.
Made for spirituality, we wallow in introspection. Made for joy, we settle for pleasure. Made for justice, we clamor for vengeance.
Justice never means "treating everybody the same way", but "treating people appropriately".
The point of justice and mercy anyway is not ‘they deserve it’ but ‘this is the way God’s world should be’, and we are called to do those things that truly anticipate the way God’s world WILL be.
Art is love creating the new world and justice is love rolling up its sleeves to heal the old one.
All human governments are intended by God to do justice and mercy - to look after, in particular, the needs of the poor and disadvantaged.
Certainly Paul shares the view of the Old Testament prophets that God will one day flood the world with justice and joy - and that this has begun to be fulfilled in the resurrection of Jesus.
Paul's vision, though, is starting small, with actual communities in which reconciliation and justice has to be practiced - like the rich/poor distinction in the Corinthian church, for instance, or the projected reconciliation between Philemon and Onesimus. But he clearly believes (Ephesians 3) that communities like this send a signal to the wider world that Jesus is Lord - which is aimed at then the whole world coming into line.
Perhaps art can help us to look beyond the immediate beauty with all its puzzles, and to glimpse that new creation which makes sense not only of beauty but of the world as a whole, and ourselves within it ... The artist can then join forces with those who work for justice and those who struggle for redemptive relationships, and together encourage and sustain those who are reaching out for a genuine, redemptive spirituality.
If you don't have properly constituted civic authorities you will encourage vigilantism and solo efforts at retributive justice - which is anarchy, and God doesn't want his world to be anarchic.
