When the Holy See gave general permission for Catholics to study again at Oxford and Cambridge, the stipulation was made that lectures be offered to provide support for their faith, as Catholics would be a minority in a rather hostile atmosphere. In the days when C. S. Lewis and J. R. R. Tolkien trod the greens of Oxford, those lectures were provided by the wise and witty Msgr. Ronald Knox, himself a convert to the Catholic Church. Erudite and profound, Monsignor Knox not only helped keep the Catholic students aflame with faith, but also led many lapsed Catholics and non-Catholics into the Church. His writings continue to provide inspiration and instruction to all those confronting questions of life and faith. Some of the best talks by Knox are gathered in this volume. "If God Exists", "The Unholiness of the Church" and "Unselfishness in Marriage" are but a few of the topics he deftly discussed in a manner as entertaining and pertinent now as when they were first given at Oxford in the 1920s and 30s.
