Cardinal Avery Dulles, SJ, is the foremost American Catholic theologian of the post-Vatican II era. This book is a religious and intellectual biography that focuses on his contributions to the development of American Catholic theology and to the larger arena of American Catholic life. The book traces his life and thought from his childhood in a prominent American Presbyterian and political family to his days as a student at Harvard where he converted to Catholicism, to his World War II experience in the Navy, to his ordination as a Jesuit, and then to his career as a theologian in the post-Vatican II era. In the entire twentieth century, no other theologian, with the possible exception of John Courtney Murray, SJ, has had as important an impact upon American Catholic thought. Dulles, though, is unmatched in the twentieth century because of his prolific publications and the wide distribution and reading of his published theology. More bishops, priests, and religious, as well as large numbers of laity, have been influenced by his writings and by any other single American theologian. This book will put his contributions to theology within the wider context of his religious life and the cultural and religious transformations in the United States during the last half of the twentieth century. †
