This article analyzes the role of the Justice and Peace Commission (JPC) of the Archdiocese of Bamenda in the management and prevention of inter-ethnic conflicts in the Northwest Region of Cameroon. It demonstrates that the active participation of this institution in peacebuilding is marked by partial success. There is much belief in the capacity of faith-based institutions to manage conflicts. However, evidence on the role of this Catholic Commission in terms of engagement and mediation in peacebuilding among warring ethnic communities is not encouraging. While its dialogue approach has significantly checked violence, its Peace Education Programme has failed to build an entrenched culture of peace. It operates in a context of significant obstacles and direly needs to beef up its operations.
