Introduction to Christianity

Why It Still Matters

Introduction to Christianity grew out of lectures Joseph Ratzinger gave before the student body of the University of Tübingen. The book’s publication in 1968, not long after the close of the Second Vatican Council, marks a milestone in the Church’s engagement with the modern world and in the career of the Church’s preeminent theologian in the public sphere. The Introduction, as an articulation of the abiding significance and urgency of the Christian mysteries, models a form of Catholic apologetic ever more necessary in a world that is increasingly post-Christian.
