This article provides an exposition of restorative justice ethics, briefly explaining how and why its relational constitution enables it to comprise a theory of justice. I then describe how that relational constitution permits it to overlap, and work in tandem, with a wide range of religious and philosophical traditions. Numerous writings in religion and peacebuilding explore the roles that restorative justice has played in transitional justice contexts (Tutu 2000, Abu-Nimer 2001, de Gruchy 2002, Biggar 2003, Walker 2004, Villa-Vicencio 2009). Less (...) examined are cases in which restorative justice aims to provide a sustainable alternative to justice institutions and systems that generate substantial systemic injustices—what peace studies scholars describe as the inter-lacing of structural, cultural, and direct forms of violence (Springs 2015). In part two, then, I make the case that intervening in, and countering, structural and cultural violence, and systemic injustices, is conceptually intrinsic to restorative justice. Moreover, this opens possibilities for restorative justice to present sustainable alternatives to—and work to transform— structural violence occurring in retributive justice systems. Restorative justice can uniquely intervene in these ways, I argue, because of the form of moral and spiritual association its relational constitution engenders. As a test case, I briefly examine its capacity to intervene in the justice system that perhaps leads the world in the levels of structural and cultural violence—the United States. (shrink)
