Drawing on the experiences and lessons of over forty years working in reconciliation, in Northern Ireland, Latin America, Africa and the Middle East, Peter B.

What is required of Christians today in the light of the increasing number of wars, insurgencies, holocausts and genocide, is a deeper understanding of what true peace making costs, and an answer to the question: 'Can Christianity continue to sanction war?'
