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

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.

A central feature of the ceremonial associated with Mithras was the taurobolium, the ritual slaughter of a bull which commemorated and repeated Mithras' primeval act. The initiate was baptized in its blood, partaking of its life-giving properties. It may be noted that this part of the ceremonial closely resembled the ritual of the cult of Cybele, the Great Mother of Asia Minor, which had been brought to Rome three centuries before Christ.

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.

If you were going to be attracted to a mystical faith which involved the contemplative life, Buddhism would be quite reasonable. But then, not everybody is a budding mystic. In fact, it's pretty certain that very few people are. So another kind of religion, one that was perhaps more pragmatic and service-oriented, might appeal to those others. So I think you have to take your values into account.

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.
