Here is another quote from Michael Gorman's Reading Paul.
"Roman justice was a way of bringing order out of chaos, but it resulted in a system of more justice for some (the elite) and less for others. Furthermore, it required a system of punishment and deterrence that included the shame of public crucifixion for those who threatened the order that Roman justice created. In other words,... Roman justice required the exclusion and even the destruction of anyone perceived to be a threat to the peace/the social order/justice. The descendants of Roman justice, including certain contemporary versions of domestic as well as international justice, inevitably follow a similar pattern, culminating in the destruction of the enemy...The saving, restorative justice of God revealed in the gospel is an alternative way of setting people right with God and with one another. It takes place not by inflicting violence to the enemy, but by absorbing violence on behalf of the enemy. Its extreme modus operandi is not to crucify but to be crucified. It does not require the destruction of the enemy but the embrace of the enemy. The justice of God, therefore, is not the opposite of compassion but the very expression of compassion. It is at once the manifestation of God's faithfulness, because this is the way God is, and of God's grace, because it is not what humans deserve. Romans 3:21-26 and especially 5:6—8 demonstrate that Christ crucified displays this kind of divine justice, simultaneously revealing that "normal" forms of justice are in fact alien to the gospel:
For while we were still weak, at the right time Christ died for the ungodly. Indeed, rarely will anyone die for a righteous person - though perhaps for a good person someone might actually dare to die. But God proves his love for us in that while we still were sinners Christ died for us. (Rom 5:6-8)"
If Gorman is right, there is much for us to reflect on.
