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.

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.

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.

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.

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.

I would like to see an agreement that recognizes that we live on the same planet and that some interests, such as human rights, must be universal and that all religions must be respected.

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.
