“I am looking forward to the rest of his series on St. Augustine.”
I am too, though perhaps for different reasons. So much of what underlies the theological differences between Orthodoxy and the Latin Church (and Western Christianity in general) are attributable, ultimately, to Blessed Augustine’s writings that it will be fascinating to read +BXVI’s take on that. Did you notice the Holy Father’s comment about +Augustine’s deficient Greek?
I don't know that he said it was "deficient." He said that while +Augustine mastered Latin, he didn't do as well with Greek. I found equally interesting Benedict's comment that +Augustine found the Latin translation of the bible to be "insufficient." In order to come to that conclusion, wouldn't +Augustine need a pretty good grasp of Greek (assuming he was comparing the Greek and Latin versions)?
A lot of scholars believe that Augustine's lack of Greek writing contributed heavily to misunderstanding over his works to begin with, and subsequently between the Latin and Greek Churches and their worlds.
Even the titles given him of "Saint" (and "Doctor") (West), and "Blessed" (East) reflect these differences.
