Impact of Ethnic, Political, and Religious Violence on Northern Nigeria, and a Theological Reflection on Its Healing [PDF ebook] 

This publication seeks to challenge established thinking about the causes of violence in Northern Nigeria. It explores immediate and long-term effects of that violence through reflection, study, and survey of previous research. The fundamental argument within is that ethnic, political and religious violence has affected Christian perspectives and core values and thus has hampered efforts towards just peacemaking.
