This volume concludes and synthesizes the extensive interdisciplinary exploration of vulnerability as a foundational category for Christian ethics. Building on the operational definition developed in the first volume—understanding vulnerability as openness to oneself, others, and God—this final section in the second volume integrates the insights from psychology, sociology, philosophy, bioethics, and theological sources. It gathers the presented trajectory of the presence of vulnerability in Sacred Scripture, Tradition, and Magisterium, highlighting its ethical and anthropological significance. The whole study further presents an ethics of vulnerability as a dynamic and generative framework for moral theology, emphasizing its potential to shape Christian ethics through compassion, relationality, and justice. It highlights the ethical and anthropological relevance of vulnerability and presents an ethics of vulnerability as a dynamic and generative framework for moral theology.
