The Western Protestant experience, which included church splits and the formation of new denominations on the basis of national, ethnic and class differences — as well as differences of doctrine, sacramental practice and biblical interpretation — had been exported to the mission fields, where many of these differences seemed to be of even less enduring significance than they were at home.
