“David Schultenover, S.J.’s monumental study of the Jesuit superior general Luis Martín (1846–1906) leaves all students of modern Jesuit, Catholic, and Spanish history in his debt. […] This archival and editorial triumph will inform the work of the next generation of historians of Spanish Catholicism, at a minimum, but should influence scholars of the modern Catholic world more generally.” John T. McGreevy, University of Notre Dame. In: Journal of Jesuit Studies, Vol. 9, No. 2 (2022), pp. 299–302.“By any measure, this work is monumental. […] It is an invaluable resource for historians of nineteenth-century Spain, modernization and laicism, church-state conflict, religion and religious life, mentalities and emotions.” Stephen Schloesser, Loyola University Chicago. In: Church History, 2022.
