Thesis advisor: Howard J. Gray / Thesis advisor: Thomas D. Stegman / This thesis attempts, first of all, to explore and reflect upon the question of “What is Jesuit leadership?” through some developmental landmarks (the founding experiences, the Formula of the Institute, the Constitutions, and the GCs 31-35 documents) within the history of the Society of Jesus. Second, it strives to argue that Jesuit leadership is essentially companionship in the Lord Jesus Christ for his universal mission, which has its depth in “Christ,” its breadth in “companionship,” and its length in “his universal mission.” / Thesis (STL) — Boston College, 2011. / Submitted to: Boston College.
