Some 40 years ago, Rev. Brian E. Daley, S.J., Catherine F. Huisking Professor of Theology, then a doctoral student at Oxford, met Rev. Joseph A. Ratzinger, then a professor of theology at the University of Regensburg, at an academic conference in Germany.
In addition to giving a lecture on Christology, Ratzinger joined the participants for several meals and presided at Mass. The young Jesuit theologian was impressed by this Bavarian colleague and greatly enjoyed the time they spent together.
