To put it a little crudely, these days nobody is afraid of excommunication. If they decide they don't want to be Catholic anymore and want to become Episcopalians or Hindus, they just do it. The churches no longer have the disciplinary powers to keep their followers in check. That means that they have to accept much more feeding up from below than they had to in the past.

People now have their own particular religion - a denomination of one. I suppose it's a part of the new age phenomenon, but it's much wider than that. On the whole, I would say that is healthy. But I think it was always there, secretly.

I think the Buddhist ethic is clearer and more systematic in some ways. The Buddhist notion is that our chief problems are greed, hatred and delusion. Well, delusion is not much mentioned in the Christian tradition. In the West, we have underplayed the idea that our moral and spiritual troubles have to do with a lack of clarity or insight because original sin has dominated so much of our thinking. We tend to think that our troubles are caused by insufficient will power.

The fact of the matter is that Buddhism has changed a lot. When St. Francis of Xavier arrived in Japan, he wrote back to the Vatican and made a joke. "It is unfortunate," he said, "that the Lutherans were here before me." By this he meant that Pure Land Buddhism was so much like Lutheranism.

I've often admired the way many Catholics who have left the priesthood, for example, have nevertheless remained sincere Catholics. They voted with their feet.

Tolerance has been a very important feature of Christianity from its very roots, despite all the other things that have gone on since. And that, I think, must be the global perspective. Tolerance implies more than saying, "Well, let the Muslims go on with what they are doing." It also means trying to learn something from them and adding that to your own tradition. That is the attitude I think needs to inform the global citizen of the future.
