First Published in 1995. This book first appeared in 1937, and includes the Apostolic Tradition of St Hippolytus which is generally recognised as the single more illuminating single source of evidence on the inner life and religious polity of the early Christian Church. With a revised preface as well as the original first edition preface.
I am fascinated to see what early Christians thought and prayed, and this treatise does offer us the thinking and faith of an early 3rd Century believer.
