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.

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.

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.

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

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.

I think the Buddhist ethic is clearer and more systematic in some ways. The Buddhist notion is that our chief problems are greed, hatred and delusion. Well, delusion is not much mentioned in the Christian tradition. In the West, we have underplayed the idea that our moral and spiritual troubles have to do with a lack of clarity or insight because original sin has dominated so much of our thinking. We tend to think that our troubles are caused by insufficient will power.

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.
