Theologians in all the great faiths have devised all kinds of myths to show that this type of kenosis, of self-emptying, is found in the life of God itself. They do not do this because it sounds edifying, but because this is the way that human nature seems to work. We are most creative and sense other possibilities that transcend our ordinary experience when we leave ourselves behind.

Religion is not about accepting twenty impossible propositions before breakfast, but about doing things that change you. It is a moral aesthetic, an ethical alchemy. If you behave in a certain way, you will be transformed. The myths and laws of religion are not true because they they conform to some metaphysical, scientific or historical reality but because they are life enhancing. They tell you how human nature functions, but you will not discover their truth unless you apply these myths and doctrines to your own life and put them into practice.

A science can diagnose a cancer and can even find a cure for it, but it can't, and a scientist will be the first to say, it's can't help you to deal with the stress and disappointment and terror that comes with a diagnosis, and nor can it help you to die well, like Socrates, kindly, not railing against faith, but in possession of your own death. For these imponderable questions people have turned to mythos.

I learned a lot from both, initially Jewish and Muslim theologians that had been missing, perhaps from my rather parochial Catholic upbringing.

God [is] not the exclusive property of any one tradition. The divine light [cannot] be confined to a single lamp, belonging to the East or the West, but enlightens all human beings.

It is people who are violent, rather than "religions"; and since we secularised our politics we have had two major world wars, the Holocaust, the Soviet Gulag, and the atomic attacks on Hiroshima and Nagasaki - none of which were inspired by religion. If we want to understand the dangers of our world, we can no longer accept the old received ideas.

Every single one of the major world faiths, whether we're talking about Hinduism, Buddhism, Confucianism, Darwinism, Judaism, Christianity and Islam, have all come to the conclusion that what holds us back from our better self is ego, selfishness, greed, unkindness, hatred. And it all springs from a sense of thwarted ego.
