Originally published in 1906, this book presents a study of 'the conceptions of the Christian Ecclesia as revealed in Christian history as a whole'. The period covered extends to the end of the second century, taking into account the development of various aspects of the Church and the ministry, and is defined by the text as the 'sub-apostolic age'. Careful attention is given to a number of documents from the period and their various points of view. Textual notes and a detailed index are also provided. This book will be of value to anyone with an interest in perspectives on the early history of Christianity.
