The British Province of the Jesuits mourns the loss of Fr John ("Jack") Mahoney SJ, who passed away peacefully in the early hours of Wednesday, 23rd October 2024, at the age of 93. Fr Jack, as he was affectionately known, lived a remarkable 74 years as a Jesuit, leaving a legacy defined by scholarly contributions, pastoral service, and a deep commitment to theology and education.
Born in Coatbridge, Lanarkshire, on 14th January 1931, Jack was educated at Our Lady's High School in Motherwell before moving to St Aloysius College in Glasgow. He went on to earn an MA in English Literature and Latin from Glasgow University, after which he joined the Jesuit novitiate in Harlaxton in 1951. This marked the beginning of a journey that would see him devote his life to the Society of Jesus and to a rigorous academic and spiritual pursuit.
Fr Jack’s Jesuit formation included studies at Heythrop, philosophy and theology, and later, a tertianship in Auriesville, New York. His dedication to moral theology led him to the Pontifical Gregorian University in Rome, where he earned his licentiate before returning to teach at Heythrop. His academic achievements soon positioned him as Dean of Theology and eventually Principal at Heythrop College. He also served on the International Theological Commission from 1974 to 1980, reflecting his influence and respected insights within the Church.
Jack’s academic journey extended beyond Jesuit institutions, earning him the FD Maurice Chair of Moral and Social Theology at King’s College London, where he fostered an ecumenical approach to Christian doctrine. He later served as Professor of Business Ethics at the London Business School, bringing a theological lens to complex ethical challenges in business and society. His tenure also included a period at Georgetown University, underscoring the international reach of his work.
Fr Jack remained actively engaged in writing and research throughout his life. Known for his prolific and sometimes provocative writings, he authored at least nine books and numerous articles, always challenging readers to think more deeply about faith, ethics, and society.
Among his many accolades, he served as chaplain to his friend Sir Francis McWilliams during Sir Francis’s tenure as Lord Mayor of London in 1992. His presence in the golden coach, journeying from the Guildhall to the Royal Courts of Justice by way of St. Paul’s Cathedral, is fondly remembered as a testament to his stature and cherished role within the community.
Reflecting on Fr Jack’s life, Fr Peter Gallagher SJ, Provincial of the Jesuits in Britain, shared: “Jack was a Scot. Among his happiest years were in Edinburgh, where he was superior of the community and founded the Lauriston Jesuit Centre. Witty, warm, and wise, Jack made friends everywhere. His views were thoroughly progressive, but he was patient and broadminded. May he rest in peace.”
Fr Jack Mahoney SJ leaves behind a legacy of scholarship, humility, and friendship. He will be remembered by his fellow Jesuits, students, and friends for his progressive spirit and patient, thoughtful approach to both faith and life. May he rest in peace, assured of the profound impact he made in his journey as a Jesuit, educator, and servant of God.
The Requiem Mass for Fr. Jack Mahoney SJ will be held at the Corpus Christi Church in Boscombe (BH7 6AN) on Wednesday, 6th November at 12:30 pm, followed by burial in the Boscombe cemetery. All are welcome to join in celebrating his life and legacy.
