A year before his death Einstein expressed in a hand written letter his views rejecting the existence of god as childish superstition. In the same letter he espoused that the Jewish people of whom he gladly belonged were nonetheless no more chosen nor special than any other. That letter is now up for auction on eBay. Per the article:

Einstein handwrote the letter in German to Jewish philosopher Eric B. Gutkind on Jan. 3, 1954, a year before Einstein's death. The letter was a response to Gutkind's book "Choose Life: The Biblical Call to Revolt" (1952, H. Schuman; 1st edition). In part of his letter, Einstein writes, "For me the Jewish religion like all other religions is an incarnation of the most childish superstitions. And the Jewish people to whom I gladly belong and with whose mentality I have a deep affinity have no different quality for me than all other people....In a March 24, 1954 letter, he is quoted as writing, "It was, of course, a lie what you read about my religious convictions, a lie which is being systematically repeated. I do not believe in a personal God and I have never denied this but have expressed it clearly. If something is in me which can be called religious then it is the unbounded admiration for the structure of the world so far as our science can reveal it." However, in the letter to Gutkind, Einstein wrote the word God was "nothing more than the expression and product of human weaknesses, the Bible a collection of honorable, but still primitive legends which are nevertheless pretty childish."
