I'm reading this right now. Rich, dense, lucid, and powerful writing. I'll be discussing it later at my "Interior Dialogues" blogsite.

Pope Benedict XVI's discourse on human and divine love is turning out to be a publishing hit.
ANSA said the 72-page document, titled Deus Caritas Est (God Is Love) -- has been reprinted three times in German and three times in Spanish, and has sold almost 1.5 million copies in Italian.

The news service said it is one of the most commercially successful doctrinal tracts ever written by a pope.

The encyclical, the first major piece of writing by the new pope, said the true nature of love between men and women needs to be clarified. The pope said erotic love can lead to degradation unless it is united with a spiritual love, ANSA reported.
