This ecumenical collection of essays on Christian initiation from a number of liturgical scholars presents analyses of ancient sources and challenges to the traditional interpretations of those sources, an investigation of the development and meaning of "confirmation," descriptions and interpretations of contemporary initiation rites, and a discussion of the challenges and opportunities offered by infant initiation. Many of these essays have long been "required reading" for teachers and students of Christian initiation. They are conveniently collected together here for all who seek a solid foundation in initiatory theology and history leading to an informed pastoral practice in the churches today.
