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.

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.

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.

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.

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.

Syncretism can be disturbing to people. They have often been taught, "You have to have solid faith and must be sure of your religion," and so on. They fear that they might be threatened by these new developments and mergings. So you get a backlash against it.

I often say that I'm a Buddhist-Episcopalian. I say that partly to annoy people.I like to annoy people who think that a religion can contain the whole truth. No religion, it seems to me, contains the whole truth. I think it's mad to think that there is nothing to learn from other traditions and civilizations. If you accept that other religions have something to offer and you learn from them, that is what you become: a Buddhist-Episcopalian or a Hindu-Muslim or whatever.
