Life is very difficult and we owe it to our fellow human beings to be as cheerful as we can.

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.

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

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.

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.
