Where is the Catholic Church going? How will it face the challenges of the 21st century? Do the recent advances in modern technology pose a threat to the human soul? In this wide-ranging, candid conversation, Cardinal Péter Erdő, Archbishop of Budapest, Hungary, one of the most respected cardinals in the Catholic Church, speaks with Dr. Robert Moynihan, founder and editor of Inside the Vatican magazine, about the Catholic Church's place in an increasingly secularized world. As the two-time president of the Council of the Episcopal Conferences of Europe, Erdő is the leading bishop of Europe. And as Europe has descended into a deep secularism—more pronounced and rapid even than in the United States—Erdő is uniquely positioned and qualified to identify and tackle the issues that secularism presents. Here, for the first time in in one place, the cardinal speaks forthrightly about the need to “guard the flame” of the traditional Christian faith in the face of all temptations and obstacles. Guarding the Flame is a courageous call to remain faithful to the faith handed down from the Apostles, whatever the cost.
