As he did to the princes of the church in his day, he has a lot to say to over-stuffed self-satisfied Americans, inclined to the Prosperity Gospel. He's our modern eco-saint, seeing himself as part of creation, not separate from him. And although a fanatic for sure, his fanaticism didn't lead to anyone getting burned. Instead of coercing others to follow his vision, he drew them to it by his joyful spirit. And his poetry is still deeply moving.
