This week I speak with Peter Gavin-Griffin, a PhD Candidate in Theological Studies at Regis College, University of Toronto, about German Catholic theologian Romano Guardini.

Here are the primary sources on Guardini that Peter mentions:

Guardini, Romano. Freedom, Grace, and Destiny: Three Chapters in the Interpretation of Existence. Trans. John Murray. New York: Pantheon Books, 1961.

Guardini, Romano. The Virtues: On Forms of Moral Life. Trans. Stella Lange. Regnery Publishing, 1967. Reprinted as: Learning the Virtues That Lead You to God. Revised edition. Manchester, NH: Sophia Institute Press, 1998.

Secondary Sources:

Balthasar, Hans Urs von Balthasar. Romano Guardini: Reform From the Source. Trans. Albert K. Wimmer and D.C. Schindler. San Francisco: A Communio Book/Ignatius Press, 2010.

Krieg, Robert. Romano Guardini: A Precursor of Vatican II. Notre Dame, IN: University of Notre Dame Press, 1997.

Ratzinger, Joseph. “From Liturgy to Christology: Romano Guardini’s Basic Theological Approach and Its Significance.” In Fundamental Speeches from Five Decades, 231–258. San Francisco: Ignatius Press, 2012. 

I incorrectly said that Harnack wrote a book called The Essence of Christianity. The actual title is, What is Christianity?
