One of Cardinal Ratzinger's most important and widely read books, this volume is a revised second edition with an improved translation and an in-depth preface by the Cardinal. As he states in the preface, since this book was first published over 30 years ago, many changes and significant events have occurred in the world, and in the Church. But even so, he says he is firmly convinced that his fundamental approach in this book is still very timely and crucial for the spiritual needs of modern man.

Considered by Joseph Ratzinger devotees as his greatest work on the liturgy, this profound and beautifully written treatment of the "great prayer of the Church" will help listeners to deepen their understanding of the rites of the Church. The cardinal discusses fundamental misunderstandings of the Second Vatican Council's intentions for liturgical renewal, especially about the priest's orientation of prayer to the Father, the placement of the tabernacle in churches, and the posture of kneeling.

Once in a generation, a historian will redefine his field, producing a book that demands to be read or heard - a product of electrifying scholarship conveyed with commanding skill. Diarmaid MacCulloch's Christianity is such a book. Breathtaking in ambition, it ranges back to the origins of the Hebrew Bible and covers the world, following the three main strands of the Christian faith.

It took nearly two millennia for the enemies of the Catholic Church to realize they could not successfully attack the Church from the outside. Indeed, countless nemeses from Nero to Napoleon succeeded only in creating sympathy and martyrs for our Catholic Faith. That all changed in the mid-19th century, when clandestine societies populated by Modernists and Marxists hatched a plan to subvert the Catholic Church from within. Their goal: to change Her doctrine, Her liturgy, and Her mission.

The Dogma of Hell explores the basic Catholic doctrine on hell, purposefully awakening in the listener a profound realization of its reality and eternity of horrors. Eminent French theologian Fr.

The Diary is an amazing narrative that chronicles the experiences of a simple, uneducated Polish nun who received a special call shortly before the outbreak of World War II.

The message of the Divine Mercy is that God loves us all of us. And He wants us to recognize that his mercy is greater than our sins, so that we will call upon him with trust, receive his mercy, and let it flow through us to others.
