Few books in theology have faced the twentieth century with all its horrors and yet convincingly revoiced the redemptive Christian antidote that compels us to reawaken to our true identity as beloved children of God. Joseph Ratzinger's 1968 masterpiece, Introduction to Christianity, is one of those rare books. On the fiftieth anniversary of this classic book's publication, English-speaking scholars from around the globe gathered at the University of Notre Dame to celebrate Ratzinger's lasting influence on the world of Christian theology. Bishops, priests, and lay men and women set their hands to "the trowel of tribute," honoring the theological legacy of Joseph Ratzinger and the pivotal role he has played in the recent history of the Catholic Church, from his early days as a parish priest and university professor, all the way to his election to the Chair of Saint Peter as Pope Benedict XVI. Readers of this collection, Gift to the Church and World, will enjoy the beautiful variety of essays penned by notable scholars that decorate the timeless insights of Ratzinger's theological genius. Thematic topics include an overview and context of Ratzinger's work, fundamental theology, philosophical theology, dogmatic theology, spiritual theology, and pedagogy. Altogether, readers will deepen their appreciation and understanding of the theological contributions of Joseph Ratzinger to the mission field of the New Evangelization today.
