Recent dissatisfaction with individualism and the problems of religious pluralism make this an opportune time to reassess the way in which we define ourselves and conduct our relationships with others. The philosophical writings of John Macmurray are a useful resource for performing this examination, and recent interest in Macmurray's work has been growing steadily. A full-scale critical examination of Macmurray's religious philosophy has not been published and this work fills this gap, sharing his insistence that we define ourselves through action and through person-to-person relationships, while critiquing his account of the ensuing political and religious issues. The key themes in this work are the concept of the person and the ethics of personal relations.
