Public justice is the guiding principle for government’s work and is comprised of two interdependent parts.
The principle of public justice recognizes that much of what contributes to human flourishing is not government’s task. This limits the scope of government’s work to promoting policies and practices that uphold the ability of other institutions and associations to make their full contributions to human flourishing.
The principle of public justice also recognizes that much of what contributes to human flourishing is government’s task. Government is authorized by God to promote what is good for human flourishing. This is often referred to as securing the common good –promoting the well-being of an entire society in right relationship with the larger world that God made. As part of this, government is also the institution authorized to restrain sin through law and provide lawful retribution for injustice.
