"This publication is a first attempt to collect data and documents on social communication in the history of the Church beginning with the bible as the first book of communication. The collection is based on the understanding of communication as 1. communication theology and 2. social communication [...] This book is more a listing and outline of data and considerations on communication in Church history rather than a detailed presentation of historical facts. It includes, however, additional texts which are beyond the presentation of basic documents on social communication." (Preface)
