Joseph Ratzinger’s Greatest Symphony: Introduction to Christianity (Course Fee)

Joseph Ratzinger has been called the “Mozart of Theology.” In this course we will read one of his early books, Introduction to Christianity, which elucidates the Apostles’ Creed in light of challenges posed by Modernity.

Introduction to Christianity launched Father Joseph Ratzinger as an international theological star. It was quickly translated into multiple languages, and earned praise from Pope Paul VI and Cardinal Karol Wojtyla, the future Pope John Paul II. It is not hard to see why. Ratzinger speaks not only to our heads, but also our hearts as he explores, first, what it means to say, “I believe,” in a world where man has replaced God with himself as ruler of the cosmos,. Then, following the Apostles’ Creed, Ratzinger explores the mysteries of God, the Incarnation, and the Church in order to lift us from our superficial modern culture  into a deeper relationship with the Lord.

Some things have changed since this book was published in 1968, but the truths it presents have not. Introduction to Christianity is as relevant today as ever, not least because in it we see themes that recurred in Ratzinger’s later theology and in his papacy. This book presents the theology of the Logos, which is a main thread for the whole of his entire theological work.

Course book: All students should buy a copy of Introduction to Christianity, Joseph Ratzinger. Ignatius Press, 2004. Available on Amazon or from Ignatius Press.
