In her book The history of God, Karen Armstrong, a former nun writes:
When I began to research this history of the idea and experience of God in the three related monotheistic faiths of Judaism, Christianity and Islam, I expected to find that God had simply been a projection of human needs and desires. I thought that ‘he’ would mirror the fears and yearnings of society at each stage of its development. My predictions were not entirely unjustified but I have been extremely surprised by some of my findings and I wish that I had learned all this thirty years ago, when I was starting out in the religious life. It would have saved me a great deal of anxiety to hear – from eminent monotheists in all three faiths – that instead of waiting for God to descend from on high, I should deliberately create a sense of him for myself. Other Rabbis, priests and Sufis would have taken me to task for assuming that God was – in any sense – a reality ‘out there’; they would have warned me not to expect to experience him as an objective fact that could be discovered by the ordinary rational process. They would have told me that in an important sense God was a product of the creative imagination, like the poetry and music that I found so inspiring. A few highly respected monotheists would have told me quietly and firmly that God did not really exist – and yet that ‘he’ was the most important reality in the world.
Professor Sir Lloyd Geering, noted New Zealand theologian and writer, would concur with the claim that “God did not really exist – and yet that ‘he’ was the most important reality in the world“. To him, God is the embodiment of our highest ideals, and not some supernatural being. Of course, Sir Lloyd would say that most Christians aren’t monotheists at all, but Trinitarianists, but that’s for another post (perhaps).
