Among the Catholics who grew to prominence in the twentieth century, few matched the public witness of Daniel Berrigan (1921-2016). This paper will develop the topic of Berrigan's use of the Spiritual Exercises of St. Ignatius as the backbone of his pacifism. This paper's approach will be threefold. First, it expands on the sparse scholarly work on Berrigan specifically as a Jesuit and a priest. Second, it examines Berrigan's own conversion alongside Ignatius's dramatic decision to lay down his weapons in Montserrat. Third, in light of this momentous development in Ignatius's life, the article will examine whether such pacifism ought to be mandatory for Jesuits today (beyond the prohibition on clerics from bearing arms in warfare), taking the particular case of Berrigan and his triumphs and trials into consideration as an example.
