Five years ago today, Pope Benedict XVI delivered a talk titled “Faith, Reason and the University” at the University of Regensburg in Germany. The lecture set off a firestorm of controversy concerning Christian-Muslim relations. On National Review Online, Acton Research Director Samuel Gregg reflects, noting that calling it “one of this century’s pivotal speeches is probably an understatement.”

Gregg says that the reaction to the pope’s speech “underscored most Western intellectuals’ sheer ineptness when writing about religion.” More seriously:

… Regensburg shattered the inconsequential niceties that had hitherto typified most Catholic-Muslim discussions. Instead of producing more happy-talk, Benedict indicated that such conversations could no longer avoid more substantial, more difficult questions: most notably, how Christianity and Islam understand God’s nature. Regensburg reminded us that it matters whether God is essentially Logos (Divine Reason) or Voluntas (Pure Will). The first understanding facilitates civilizational development, true freedom, and plete understanding of reason. The second sows the seeds of decline, oppression, and unreason.

But perhaps above all, Regensburg asked the West to look itself in the mirror and consider whether some of its inner demons reflected the fact that it, like the Islamic world, was undergoing an inner crisis: one which was reducing Christian faith to subjective opinion, natural reason to the merely measurable, and love to sentimental humanitarianism. The West, Benedict suggested, was in the process of a closing of its own mind.
