"In Service of Two Masters contributes a nuanced narrative of the Franciscan evangelization political strategies and failure through a case study that exposes the defining role of imperial, viceregal, and local ecclesiastical politics in the spiritual conquest of the Spanish borderlands....a fine addition to the comprehension of the Spanish empire's mission frontiers, transatlantic studies of church-state relations, and Franciscan history more broadly."—Alcira Dueñas, The Journal of Religion "In Service of Two Masters is a fine contribution to mission history that will also appeal to those interested in the local impact of the Bourbon reforms. Jones puts the voluminous Franciscan writings of the era to good use, as well as his extensive research in Peruvian and Spanish archives."—S. Elizabeth Penry, Hispanic American Historical Review
