Faced with the resurgence of wars and armed conflicts in the world, voices are being raised to propose solutions. Peace is the new paradigm that we propose in science, it should be studied like any other object and allow to pacify the diplomatic as well as social relations. The theology of peace is an effective model that thinks peace from the transcendent, peace being a gift of God, the divine peace thus founds and supports the social and political peace. It is to this problem that René Coste and Joseph Comblin have dedicated their efforts through a similar theme, even though they lived in two different times, at different moments and in different contexts. With them, we are a school and we have the privilege of extending their reflection in the African context and therefore in the Congolese context, a context dominated by violence and war. The aggression of the Democratic Republic of Congo by Rwanda through the M23 and other rebel groups illustrates this context well. This bookis an asset for countries at war and post-conflict countries.
