A Man for Others: Pedro Arrupe s trinitarian mystic and its impact on the twentieth and twenty-first century ecclesial renewal proposes the resignification of mystic for today s world based on his life and mission. The Jesuit priest Arrupe, as many other contemporary mystics, such as Simone Weil, Etty Hillusum, Thomas Merton and Christian de Chergé – left their mark on the last century and, even today, bear real witness to the possibilities of the establishment of God’s Reign in history. Those contemporary mystics, among others, fed by a deep experience of the ineffable, were sources of light and hope for the world, even in conditions of extreme suffering. Pedro Arrupe lived through a troubled moment in history, marked by World War I and World War II and by the Cold War. During his lifetime, even the Church faced periods of internal tension trying to adapt itself to the aggiornamento changes brought about by the Second Vatican Council. While serving as the Superior General of the Society of Jesus, supported by his own deep and private mystic, he took upon himself the task to collaborate with the Second Vatican Council proposal to open the Church to the world. His life was an example of commitment to working for those in need, and, among many of the battle fronts he had to face, we can mention the promotion of faith with justice and the dialog with other cultures and religions, with special emphasis on the plight of refugees and migrants. Arrupe is considered by many as a prophet ahead of his time, and, as such, often misunderstood. However, the seeds he planted did bear fruit and found fertile soil in many people that knew him and those who were touched by him. Pope Francis is a good example. He is also a Jesuit who shares the same spirituality, and tries to implement, based on the same Biblical basis, the guidelines that were dear to his former Superior General.
