In this book, Paul O'Callaghan turns to the epistemological framework of witnessing. From a religious standpoint, witnessing is a foundation for belief in divine revelation. Pivotal in Biblical texts, especially in John's gospel, witnessing is similarly at the heart of Christian evangelization. Ideally, witnessing avoids the opposing extremes of fundamentalism and skepticism and, instead, points us towards divine truth. This book explores the idea of truth and the communication of truth through witnessing. O'Callaghan offers an overview of philosophical and theological epistemology, introduces the notion of witnessing within philosophy, and examines how Jesus Christ's death on the Cross and subsequent Resurrection provides witness to the truth. This dynamic of witnessing is then applied to the lives of contemporary Christians who give witness to the truth in a variety of ways. At its core, O'Callaghan brings together both theology and philosophy, considering how the rationality of the witnessing process leads to a person-centered anthropology.

Paul O'Callaghan is professor of theological anthropology at the Pontifical University of the Holy Cross (Rome).
