If you've had the opportunity to read any of Pope Benedict XVI's writings, you've probably come to the same conclusion that I have: it would be tough to win a philosophical or theological debate with this man.
Aside from his dozens of books, his theological writings are astounding in their depth and number. A reader kindly directed me to "Current Situation of Faith and Theology" from 1996. After reading it, all I can say is "Wow!" He's not an easy read, but it's well worth the intellectual, and spiritual, journey.
The former Cardinal Ratzinger admired "Democracy in America" by Alexis de Tocqueville. Freedom is the central theme of his writings. The beginning of creation is a "creative freedom which creates further freedoms." He describes Christianity as "a philosophy of freedom."
It's uplifting, very profound material. In starting to read the written works of Pope Benedict XVI, I've begun some truly higher education.
