Some scholars count Christianity as one of the violent religions. Their evaluation is often based on the violent texts in the bible, the Crusades and the Inquisitions of the Medieval Age. Scholars of this option do not bother much about the wars some Islamic groups, like Boko Haram in Nigeria, wage on Christians. In Nigeria, many lives and properties have been lost due to these horrendous onslaughts. This article establishes that Christianity is a ‘pacific’ religion which preaches and practices  ‘love of enemies.’ The crusades and the Inquisitions were only a stage in the development of the true Christian doctrine on war and violence, which has been long overtaken bu the modern teaching. This paper will attempt to give some recommendations that could lead to a better rapprochement between Christians and Muslims in Nigeria and worldwide.
