This article presents a rigorous examination of the imperative for the Catholic Church to activate its canonical mandate in the contexts of severe social strife, using the human rights emergency in Nigeria Southeast as a paradigmatic case study. It posits that Canon 747§2 of the 1983 Code of Canon Law, which charges the Church to announce moral principles and render judgement on human affairs to protect fundamental human rights and salvation of souls provides a non-negotiable juridical and theological framework for pastoral action. The analysis is made within the crisis separatist agitation, state militarization, and communal breakdown in Southeast Nigeria. Through detailed documentation of violations of human rights by both state and non-state actors, and a critical evaluation of the local churches’ response, the article argues that a robust application of canon 747§2 is essential for credible prophetic witness, pastoral resilience, and the defense of human dignity. It concludes with a comprehensive, actionable set of recommendations for integrating Canon 747§2 into Church governance, advocacy, and formation, offering a model for ecclesial engagement in conflict zones globally.
