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 from the perspective of the missions of earlier centuries. Between the missions of which Professor Addison writes 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 the Motives of Medieval Missionaries; Kings Missionaries; Missions Monasticism Influence of the Papacy; Missionary Message.
