This study presents a theological analysis of the hermeneutic and ethical challenges of truth-telling in the pursuit of justice within the context of transitional justice in South Africa. The main research objective of the study is to deepen understanding of the exchange between theological perspectives on truth-telling for justice, and the enacted mandates of transitional justice. This exchange is drawn from the Truth and Reconciliation Commission (TRC) and is shown to have implications for the public theology of the Dutch Reformed Church in South Africa. The first chapter introduces and frames the systematic, theological rationale and methodology of the study and the chosen hermeneutical contours concerned with historical theology, Christian ethics, and public theology. A porous division is introduced between ascribing truth and constituting truthfulness, in order to test the theological argument for the embodiment of truth-telling. Naming this division is a descriptive attempt that contributes to contouring the challenges of avowing truth while embodying justice. Based on a public theological rationale and methodology, these challenges are addressed as theological problems with consequences for Christian public witness. Chapter Two and Four explore these challenges of truth and truthfulness as enacted in both the Truth and Reconciliation Commission (TRC) (Chapter Two) and in Reformed public theologies in South Africa (Chapter Four). In Chapters Three and Five, two conversation partners are chosen to aid the analysis of the challenges of truth-telling; Michel Foucault, primarily in conversation with the TRC, and Dietrich Bonhoeffer in conversation with Reformed public theologies in South Africa. The historical philosophy of Foucault on regimes of truth is taken from his Louvain lecture series Wrong-Doing, Truth-Telling: The Function of Avowal in Justice (Chapter Three). As a long-standing conversation partner in the formation of public theologies in South Africa, Dietrich Bonhoeffer’s thought on truth-telling ...
