Our common belonging to Christ through baptism creates a bond that transcends the historic and theological differences among the churches; and the mutual recognition of baptism has emerged as a cornerstone of the modern ecumenical movement. Yet significant differences--some threatening the search for the unity of the Church--remain. This book explores the significance of baptism for the churches, and the ecumenical movement, today. Descriptive articles explain the understanding and practice of baptism within a wide range of Christian churches and confessions; these are complemented by baptismal liturgies from many churches, examples of mutual recognition agreements, and reflections on topics such as the role of baptism in increasingly secularized societies. The volume is enhanced by survey articles by prominent liturgists, reviewing the current opportunities--and challenges--facing the churches in the area of baptism. This book will be an important resource for all who wish to explore the understanding and practice of baptism, and its role in the life of the churches and of the ecumenical movement today.
