On the occasion of Ratzingers's seventy-fifth birthday, his former students selected essays, lectures, letters, and conferences that Ratzinger has written in recent years-- writing that they feel best represents his position on issues of theology, the modern world, secularism, non-Christian religious, and other key topics of the Catholic Church. This book, characterized by Ratzinger's concisely reasoned style, is an invaluable resource to those who wish to understand the modern Church and the thinking of Pope Benedict XVI, as well as a treasured volume for those who are students of Ratzinger's theology.
