This chapter explores the Church of England’s response to the Suez crisis, where Geoffrey Fisher, the Archbishop of Canterbury, found himself at odds with government policy and with many of the church’s own members. Aware of the collusion between Britain, France, and Israel, he asked awkward questions about the origins of the crisis, about the legality of Britain’s actions, and he suggested that this adventure would damage Britain’s international reputation. During this crisis he engaged in correspondence and meetings with several leading politicians, and increasingly questioned the judgement of Anthony Eden. At the same time, his interventions were questioned by those who still believed an established church’s primary role was as cheerleader for the government of the day, especially in times of war. In the decades following the crisis the church engaged in more sophisticated debates about ethics and the use of force, and the chapter ends with a brief discussion of contributions to this discussion made by Michael Ramsey, Fisher’s successor.
