I am neither a German citizen nor do I believe in anything that can be described as a "Jewish faith." But I am a Jew and glad to belong to the Jewish people, though I do not regard it in any way as chosen.

Letter to Central Association of German Citizens of the Jewish Faith, 3 [5] April 1920, as quoted in Alice Calaprice, The Ultimate Quotable Einstein (2010), p. 195; citing Israelitisches Wochenblatt, 42 September 1920, The Collected Papers of Albert Einstein, Vol. 7, Doc. 37, and Vol. 9, Doc 368.
