In his most recent book entitled "To Sanctify the World: The Vital Legacy of Vatican II," George Weigel explains the necessity of the Second Vatican Council (1962-1965) and explores the continuing relevance of its teaching in a world seeking a deeper experience of freedom than personal willfulness. The Council’s texts are also a critical resource for the Catholic Church as it lives out its original, Christ-centered evangelical purpose. The lecture and accompanying discussion will further explore the meaning of Vatican II as the most important Catholic event in the past five hundred years.
