This week I continue my exploration of the life, career, and work of our new Pope, Joseph Ratzinger. In the years after the council, a split occured in the ranks of the Conciliar progressives, some calling for deeper and broader reform and others calling for a more careful appropriation of Vatican II. Joseph Ratzinger, along with Henri de Lubac, Hans Urs von Balthasar, and Karol Wojtyla, belonged to this latter group. The commonality between Ratzinger and Wojtyla led to John Paul II's choice of Ratzinger as his Prefect for the Congregation of the Doctrine of the Faith.
