This is the first of a written debate between him and Kurt Aland. This book is primarily a book of history. Whatever theology is addressed is more an accident of the historical question. Jeremias, arguing for the continuous Christian practice of infant baptism, takes us on a journey through the historical evidence in favor of its early practice. He addresses the New Testament text and evidence, early church fathers, and tombstone inscriptions. I personally found the discussion of baptism's relation to circumcision and the early baptismal/sacramental use of “Let the children come to me” was of most interest. This is a short work, only 98 pages. It is insightful for anyone interested in Church History, Sacramental Theology, or baptism in general.
