This is a portion from a much larger piece from Georgetown's website, author unkown. Arrupe is described as a "Second Founder", Is not St. Joseph Pignatelli, S.J., the real "Second Founder"?
Arrupe's mark on the Jesuits is still felt today. During Vatican II, when the Church strove to modernize itself to reach out to more people, Arrupe in 1965 became superior general of the Society of Jesus. He pressed fellow Jesuits to serve more marginalized people and fight for justice. Turmoil within some sects of the Jesuits marked Arrupe's time in the position because some dissenters believed he made too radical changes and politicized the order.
