For twelve of the years during which he spent a semester lecturing as a visiting professor at the Gregorian University (Rome), Frederick Copleston enjoyed close contacts with Bernard Lonergan. He was one of the two ‘house’ censors of Insight. He also wrote a very positive review of the book for the Oxford-based Journal of Theological Studies, which was then co-edited by Henry Chadwick. The personal and professional contacts between Copleston and Lonergan have been widely neglected; they call for further study and evaluation.
