Writing the history of the Society of Jesus would be a daunting task for any historian. Luckily, John O'Malley has some advantages. First and foremost, Father O'Malley is himself a Jesuit. Because of his membership in the order, he wrote this book with access to the Monumenta Historica Societatis Iesu, the one hundred and twenty-five volume collection of letters and manuscripts associated with the history of the Society. In addition to the use of this and other excellent primary sources, O'Malley wisely sets strict limits on the scope of his project. His book focuses only on the first twenty-five years of the Jesuits, from its foundation in 1540 to 1565, an end date that the author admits is rather arbitrary but allows him to draw an organic and complete picture of the early goals, achievements, and frustrations of the Jesuits. The presence behind the entire work is Ignatius, the first general of the order and, to O'Malley's mind, the single causative element of the Society's foundation and success. It was Ignatius who not only developed the vision of the Society, but dictated their "way of proceeding," the uniquely Jesuit modus operandi. O'Malley's main argument, stated succinctly in both his introduction and conclusion, is that without Ignatius there would have been no Society of Jesus.
The book's logical structure helps O'Malley support his thesis. A fusion of narrative and thematic exploration, the first half of the book examines how the Jesuits pursued the responsibilities they assigned to themselves as their consueta ministeria, or "customary ministries." These were the tasks the first group of confreres set down for themselves as the very reason for being for the Society of Jesus - they included public preaching, education of children and adults in the Word of God, and a myriad of other charitable works. O'Malley devotes chapters to Jesuit work with orphanages, hospitals, street preaching, and the schools. The last half of the book deals with less corporeal topics, and discusses the place of the Jesuits within the Catholic Church, their expressions of piety, relation to the Protestant Reformation, and calcification of the rules of the Society. O'Malley studies all of these themes through three motifs: the writings of the Jesuits, especially Ignatius's Spiritual Exercises; the Jesuit sense of their mission being "to help souls"; and the ultimate expression of the many threads of their existence in the foundation and promulgation of their colleges. Ignatius was the source of most of the early prescriptive documents of the Society, and it was his vision and zeal that imprinted the sense of mission on his confreres. Finally, as the man responsible for the creation and administration of the early educational system set up by the Jesuits, Ignatius is justified as being the primus inter pares of O'Malley argument.
Besides constructing a thoughtful and accessible history, O'Malley also succeeds by making his book an example of fine craftsmanship. Using primary sources in Latin, Spanish, and other languages, his writing has copious support and documentation. This accomplished scholarship should be no surprise, since O'Malley received his doctorate from Harvard, has taught there as well as Fordham and Oxford, and has served as the president of both the Catholic Historical Society and the Renaissance Society of America. He does mention that some of his sources, especially the correspondence of Ignatius, may be clouded due to the customary use of secretaries - the example here is that the preponderance of Ignatius's letters were written only once he had appointed Polanco to act as his secretary, and so Polanco doubtless served as a filter for the general's expression. Despite these minor quibbles (and perhaps because of the academic integrity displayed by mentioning them), O'Malley's book is eminently useful as a cultural history of the Society of Jesus and the role it assumed in the sixteenth century Church.
