I agree with Prof. Dawkins expressions of religious tolerance but take issue with how he describes Einstein’s religion. Dawkins in this clip and in his book the God Delusion, claims that Albert Einstein was a Pantheist, to substantiate his own position of being an atheist. But, the fact of the matter is that Einstein, like the Founding Fathers of USA, was a Deist. This should become apparently clear, by reading of my article about Albert Einstein and definition of Deist and Pantheist. After all Einstein did believe in Spinoza’s God. Of course, as a Deist, he did not believe in a Personal God!
The word Piper should make one think of Deism and not Pantheism 
So, if Einstein said, “Everything is determined, the beginning as well as the end, by forces over which we have no control. It is determined for the insect, as well as for the star. Human beings, vegetables, or cosmic dust, we all dance to a mysterious tune, intoned in the distance by an invisible piper,” does it sound like Pantheism or Deism to you?
He also said on another occasion the words embedded in the following picture:
There is no denying that Einstein denied Personal God on more than one occasion, but, his life, his pursuit of science, his commitment to Judaism and Israel, his writings and quotes about nature, science and religion can be comprehended only if he is understood to be a Deist, someone who believes in a Creator God, who does not answer prayers. Prof. Dawkins defines the terms of theism, deism, pantheism and atheism, in the first chapter of his book, the God Delusion and at one point also writes, “Pantheism is sexed up atheism. Deism is watered down theism.” But, as the Pope of atheism, Prof. Dawkins issues his Papal Fatwa that Einstein was a Pantheist more than once in this very first chapter of his book, but, as is the case of many of his contemporary Mullahs, he offers no arguments and reasons for his Fatwa! You be the judge! Read his book, my article about Albert Einstein linked in this post and the comments below and see for yourself, is Dawkins correct in claiming him to be a Pantheist or this humble one in calling Einstein a Deist?
