Shame-Less Lives, Grace-Full Congregations." If her book's anything like her lecture, it's worth reading.
That said, one could have walked away from her lecture (and perhaps after putting down her book) with the impression that the church is actually less psychologically healthy (i.e., more shame-based) than the world at large. Such an impression would be mistaken, however. As I've noted previously ("How Religion Benefits Everyone, Even Nonbelievers"), people of faith, on average, enjoy better mental and physical health than people with no faith. That is, they are more likely to happy, healthy, and live longer lives. Thus, churches (and synagogues, temples, and so on) must be doing something right.
