How can one set about describing a spiritual movement as it is perceived from the very varied viewpoints of the members of a whole organization such as the Church Missionary Society? The General Secretary of such an organization is likely to have shared the perceptions of a whole variety of its differing members and thus, perhaps, I have gained some kind of a common view. So it seems best to begin with my own overall impression of the East African Revival and then to set that in the perspectives of my two, unquestionably far greater, predecessors, Max Warren and John Taylor, each of whom recorded a view of the movement which the CMS had come to at two earlier stages in its history.
