“For God does not want to be believed in, to be debated and defended by us, but simply to be realized through us.”
Martin Buber

Your question is the most difficult in the world. It is not a question I can answer simply with yes or no. I am not an Atheist. I do not know if I can define myself as a Pantheist. The problem involved is too vast for our limited minds. May I not reply with a parable? The human mind, no matter how highly trained, cannot grasp the universe. We are in the position of a little child, entering a huge library whose walls are covered to the ceiling with books in many different tongues. The child knows that someone must have written those books. It does not know who or how. It does not understand the languages in which they are written. The child notes a definite plan in the arrangement of the books, a mysterious order, which it does not comprehend, but only dimly suspects. That, it seems to me, is the attitude of the human mind, even the greatest and most cultured, toward God. We see a universe marvelously arranged, obeying certain laws, but we understand the laws only dimly. Our limited minds cannot grasp the mysterious force that sways the constellations. – Albert Einstein.

Albert Einstein was quoted in The New York Times, November 9, 1930, saying: “I assert that the cosmic religious experience is the strongest and noblest driving force behind scientific research.”

As recorded by Helen Dukas in Albert Einstein, The Human Side (Princeton University Press, 1981, p. 66), Einstein stated: “My religiosity consists in a humble admiration of the infinitely superior spirit that reveals itself in the little that we, with our weak and transitory understanding, can comprehend of reality. Morality is of the highest importance-but for us, not for God.”

Walter Isaacson quoted Einstein in the article “Einstein and Faith,” Time 169, April 5, 2007, 47): “The fanatical atheists…are like slaves who are still feeling the weight of their chains which they have thrown off after hard struggle. They are creatures who – in their grudge against the traditional ‘opium of the people’ – cannot bear the ‘music of the spheres’.”

According to Prince Hubertus (Ronald W. Clark, Einstein: The Life and Times, New York: World Publishing Company, 1971, p. 425), Einstein said: “In view of such harmony in the cosmos which I, with my limited human mind, am able to recognize, there are yet people who say there is no God. But what really makes me angry is that they quote me for the support of such views.”

Einstein wrote to M. Berkowitz, 1950, (William Hermanns, Einstein and the Poet. In Search of the Cosmic Man, Brookline Village MA: Branden Books, 1983, p. 60): “‘God’ is a mystery. But a comprehensible mystery. I have nothing but awe when I observe the laws of nature. There are not laws without a lawgiver, but how does this lawgiver look? Certainly not like a man magnified.”
