Buddhism and Christianity are incompatible because there is no God in Buddhism - particularly in Theravada Buddhism. But they are also allies because their values and practices are compatible and they can work together - indeed, they would benefit greatly from doing so.

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.

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.

I think the attractiveness of Buddhism is that it doesn't involve a belief in God. That appeals to a lot of people - intellectuals and well-educated people in particular.

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.

Children become more liberal partly as a reaction to their parents and partly through education. Education tends to make people a bit softer.

One of the effects of religions getting together is that they borrow from one another. An example is the growing number of Catholics who are practicing Yoga and meditation techniques borrowed from Buddhism and Hinduism. So there are these borrowings which I think fertilize the religions.
