This volume takes its cue from the theme of the International Eucharistic Congress to be held in Dublin in June 2012, ‘Communion with Christ and with one another’. In almost eighty short articles, a host of leading scholars from the worlds of history, liturgy, theology, philosophy, art history and Celtic Studies reflect upon aspects of the history of the Christian tradition in Ireland from the fifth to the twenty-first century, with a special emphasis on the relationship between the Irish people and the Eucharist. This is a wide-ranging illustrated collection which draws from the major Christian denominations in Ireland and includes entries on significant people, texts, images and events that have shaped the Irish Christian experience.
