In The City of God (XIX, 23), Augustine explained where to find justice:

Justice is found where God, the one supreme God, rules an obedient City according to his grace, forbidding sacrifice to any being save himself alone; and where in consequence the soul rules the body in all people who belong to this City and obey God, and the reason faithfully rules the vices in a lawful system of subordination; so that just as the individual righteous person lives on the basis of faith which is active in love, so the association of righteous people lives on the same basis of faith, active in love, the love of with which a person loves God as God ought to be loved, and loves their neighbor as himself.

A few things to note. Justice is undermined and ultimately rendered impossible where:

• We worship/sacrifice to other gods (typical gods for us are: money, power, fame, pleasure, self)
•  The souls of people are not ruling over their bodies

Justice is present when we:

• Order our lives first around an active, personal relationship with the Divine, trusting in Grace, acting in Love in all things
• Order our lives second around active, personal relationships with everyone around us, trusting in Grace for each other, acting in Love towards all in all things
• An active, lived understanding that these two orderings are interrelated and inseparable

Reflect on the ideal Augustine describes versus the reality we see, and even the way average Amercian Christians have ordered their lives and the implicit ideal that implies, and I think you’ll see how far from Justice we are right now. May we find our way back. 

Todd Hunter in Bill Jackson’s The Quest for the Radical Middle, p.366-7:

One of the reasons we are increasingly without a voice in our culture is that we’ve “dumbed down” Christianity to a ludicrous level. Perhaps it’s time we help people begin to learn a new vocabulary, hear some new stories, and experiment with some distinctive practices. And perhaps it’s time that Christians live lives that are so intriguing, so interesting, so compelling, that people naturally want to understand what it is that causes us to live the way we do.

Is man seeking God or is God seeking man? Perhaps man is hiding, pretending to seek God, but is really looking for a safe and predictable “god.” And maybe as we dumb Christianity down, we play right into this scheme by becoming vendors of religious goods and services in order to meet people’s pretend needs.
