It sounds superficially fair. But it presupposes that that there is something in Christian theology to be ignorant about. The entire thrust of my position is that Christian theology is a non-subject. It is empty. Vacuous. Devoid of coherence or content. I imagine that McGrath would join me in expressing disbelief in fairies, astrology and Thor's hammer. How would he respond if a fairyologist, astrologer or Viking accused him of ignorance of their respective subjects?

Textbooks describe DNA as a blueprint for a body. It's better seen as a recipe for making a body, because it is irreversible. But today I want to present it as something different again, and even more intriguing. The DNA in you is a coded description of ancient worlds in which your ancestors lived. DNA is the wisdom out of the old days, and I mean very old days indeed.

Maybe somewhere in some other galaxy there is a super-intelligence so colossal that from our point of view it would be a god. But it cannot have been the sort of God that we need to explain the origin of the universe, because it cannot have been there that early.

There does seem to be a sense in which physics has gone beyond what human intuition can understand. We shouldn't be too surprised about that because we're evolved to understand things that move at a medium pace at a medium scale. We can't cope with the very tiny scale of quantum physics or the very large scale of relativity.

The idea that God could only forgive our sins by having his son tortured to death as a scapegoat is surely, from an objective point of view, a deeply unpleasant idea. If God wanted to forgive us our sins, why didn't he just forgive them? Why did he have to have his son tortured?

It is possible to enjoy the Mozart concerto without being able to play the clarinet. In fact, you can learn to be an expert connoisseur of music without being able to play a note on any instrument. Of course, music would come to a halt if nobody ever learned to play it. But if everybody grew up thinking that music was synonymous with playing it, think how relatively impoverished many lives would be. Couldn't we learn to think of science in the same way?

If there is something that appears to lie beyond the natural world as it is now imperfectly understood, we hope to eventually understand it and embrace it within the natural. As ever when we unweave a rainbow, it will not become less wonderful.
