John Paul II could not accept open debate and discussion in the church. Loyalty was more important than intelligence or pastoral skill. As a result, the quality of bishops appointed under him declined, as did the competence of people working in the Vatican.
This is not to downplay John Paul's important role in world affairs. He was much more important to the peaceful fall of Communism than Ronald Reagan. He also did more to improve Catholic relations with Jews than any pope in history.
But the sad truth is that while he was good for the world, he was bad for the church. His suppression of theological discussion and debate, his insensitivity to women's issues, and his appointments kept the church from responding pastorally and intelligently not only to the sexual abuse crisis but to other issues facing the church.
I have no doubt that John Paul is in heaven, but the effort to canonize him should be put on hold
