There is, as yet, little scholarly work on Spain’s small protestant minority, and this first full-length study of British missionaries is therefore to be welcomed. . . .The book provides many insights. There is a welcome acknowledgement of Protestantism’s association with the working class and the poor in Spain, which the author associates with limiting the missions’ impact, given the failure to penetrate the elites. There are also illuminating discussions of the women who were involved in mission work. . . .One of the most attractive, if unconventional, features of the book is a sense of dialogue between the author and his sources, which reflects his insider position. He takes his protagonists seriously, treats their thoughts and feelings with respect, and fully recognizes the extent of their pastoral task. . . .This is, in short, an interesting and thoughtful…contribution to the understudied field of Spanish Protestantism.
