From this review of Bonzo's and Stevens' guide to Berry, this quote:
The authors begin with the claim, "If we were asked to name one person to whom contemporary Christians need to listen, it would be this unlikely source, a man with no important connections to ecclesial or political corporate power." I would say this applies for all Americans today: Berry is the great prophet of our time and place.
And I doubt Messrs. Bonzo and Stevens would mind if I recommend that those new to Berry begin with his own books. Get a copy of his collected essays, or the poetry volume A Timbered Choir, or his sweeping novel Jayber Crow. Go someplace quiet and settle in. Prepare to have your worldview—whatever it is—upset. That's what prophets do.
