I read this in NPR's report
on the book:
"whatever happens to the institutional churches, individual Christians can try to essentially be better Christians, and honor the complications and paradoxes and tensions of this ancient faith a little better, and not just go as quickly to the easy answer"
He raises a lot of good points, but this quote is a heresy unto itself. There is no Christian apart from the Church. This individualist heresy is what gives rise to all the others. So, while his critiques may turn back the clock to a more confessional type of Protestantism (which is better than nothing, I suppose), it does not fix the problem.
"We are saved together; we are damned alone." But it will be nigh impossible for people give up their radical individualism in their religious beliefs.
