The testimony and teachings of Joseph Ratzinger on the act of faith are particularly urgent for the Church today. Doctrinal confusion and other signs of crisis experienced by believers find their root in a crisis of faith. Understanding what it means to believe is more than an academic exercise; rather, it is a necessary step for authentic renewal in the Church.

In this book, Fr. Daniel Cardó outlines the different insights of Joseph Ratzinger on the act of faith - understood as a personal, integral, and ecclesial act. Cardó provides an organic view of the rich contribution made by the Pope Emeritus in his many theological works.

What Does it Mean to Believe? is also an invitation to appreciate the mind and the faith of one of the greatest theologians of our time.
