That we might find support in the faith and overcome the present temptation to apostasy, schism, and resignation, but at the same time not succumb to the danger of overestimating ourselves and relying on our own activity instead of on grace—that is the goal of the present book. –from the Introduction

"You shall know the truth," Jesus said, "and the truth will make you free" (Jn 8:32). Such is the liberating power of truth. In this book, Gerhard Cardinal Müller, former head of the Vatican's Congregation for the Doctrine of the Faith, unabashedly defends the truth of salvation taught by Christ and the Roman Catholic Church. He discusses how Catholic teaching addresses present-day crises in the Church and in the world.

This book also includes the cardinal's recently released Manifesto of Faith. Relying heavily on The Catechism of the Catholic Church, it clarifies certain Church doctrines that have lately seemed to be in doubt.
