This work is No. II in the Studies in the World Mission of Christianity Series. Through this book we can see the modern missionary enterprise against the background and from the perspective of the missions of earlier centuries. Between the missions of which Professor Addison writes and those of the last century and a half many striking contrasts exist which inevitably raise questions concerning the infallibility of those which have been pursued in our age. Contents: Education and the Motives of Medieval Missionaries; Kings and Missionaries; Missions and Monasticism Influence of the Papacy; Missionary Message.
